It's been a long time since I posted a thread about one of my cars, but I wanted to share my most recent purchase. The older members on here might remember the 1991 diamond black 318i Lux I bought back in 2005, and the 1990 dolphin grey 325i Sport I bought in 2007, and then restored - Beardymatt carried out the extensive bodywork repairs. I sold that car back in 2011, and bought a 1988 Macau blue E30 M3 EvoII, which I gave a nut on bolt re-build. I have also had a couple of other E30s since 2011, including a 1990 325i convertible for a couple of years. One car I always missed though, was the Tech II 325i Sport, and last year I decided to get another one, ideally in diamond black.
The majority of Sports for sale are scrap, even the ones claiming to be excellent examples. A lot of the supposedly nice ones are being sold by dealers who know nothing about them, not enthusiasts who know the individual car well. I eventually found a low mileage one in diamond black from a private seller, and we agreed a deal in July. The seller had never driven the car, despite it being MOTd and taxed, and it had sat in his garage for quite a while. The car was a long way from where I live, so I had it transported to me on a trailer rather than risk a long first drive. It's is a 1989 325i Sport and has covered just 44k miles, and since 1993 has only covered 4k miles. Aside from the usual Sport spec, it was also fitted from new with a 13 button OBC, rear head rests, and heated washer jets, mirrors and door lock. It has a fantastic service history, every MOT from new and even the original sales invoice, and although the car was MOTd almost every year, it covered very few miles. This has been excellent for preserving it, however also resulted in a few things which need attention. My plan is to give the car a thorough overhaul, keeping it entirely OEM (although adding a few factory optional extras, which could easily be removed again if wanted), and correcting the few small non-OEM parts on the car currently. Just prior to me buying the car, it was given an inspection II service, new cambelt, new tyres and new SI board. Not long ago the brakes were also fully rebuilt (callipers blasted, re-coated and rebuilt, and new discs and pads), so that was some items ticked off already.
Loaded for it's journey home:
Delivered! :
The MOT had recently expired, and so after a thorough look over the car, the first thing was to drive it to the MOT station. I noticed that the car was running a bit warm in traffic, and suspected the viscous clutch, given how long the car had sat for. This was the problem, and I fitted a new Behr clutch (the manufacturer of the OEM clutch). The car also passed the MOT.
The second time out in the car the fuel pump started to whine loudly, and I assumed the worst - that the fuel tank had rusted from the inside, due to sitting for so long with old fuel in it. When I got home I removed the pump, and not surprisingly the tank was lightly rusted inside, and the fuel was a brown colour. I'm surprised the car ran so well none the less. Perhaps the old fuel had been drained and swapped once already. I contacted BMW and ordered a new fuel system from the filler pipe through to the engine. The only part I decided not to buy from BMW was the tank itself, as they wanted almost £1k for one, and the ones I have bought from GSF before have been almost identical, and a similar weight/quality. So, I bought one from GSF (these are about £550 on their website, but still £260 on ebay, so grab a bargain before they sync their price lists!). The non-BMW tanks come finished in silver coating, not the BMW black finish, and so I finished my tank in satin black, per OEM. I replaced every fuel fitting along the way, although didn't take pictures I'm afraid.
Here is the tank while the finish is still drying, so it looks shiny:
It seems I can only upload 5 pictures in this post, so I'll split this accross a few posts...

As part of the job of changing a fuel tank, the exhaust and prop shaft have to be dropped down. It was a good time to fit new exhaust parts, and the associated heat shields. Note that 325i Sports had shadowline trim tips fitted to the rear box, not the chrome ones people often fit. Luckily the exhaust and all associated parts are still available from BMW.
Whilst under the car it was a good time to sort out a few more areas. In the driver side rear wheel arch you will find the fuel breather equipment, along with the fuel filler pipe. The whole lot forms a bit of a trap for mud, and this is one of the first places that E30s often rot from. Somebody had added some extra protection in this rear arch, presumably when the car was near new, by screwing a thick rubber mat to the existing small plastic mud shield, which prevented any mud getting chucked up into the arch. Given the car wont be driven in the wet any more, I removed all of this and bought new fittings for the arch. The car had been waxoyled in the past, but some muppet had sprayed this over the shell before cleaning it, so it was on top of mud etc! It was made even worse by the dealer who sold the car in 2016 spraying yet more waxoyl on top! I cleaned it all back thoroughly using white spirit, and luckily no rust had set in yet. Perhaps the cleanest E30 shell I have seen, let alone Tech II kitted car. I also removed the M-tech II kit from the car to be certain there was no rust, and thankfully found none at all, and no sign of the car ever being welded anywhere. The clips to fit the kit are still available from BMW, and best to replace after removing it as some of them are single use only.
Somebody had fitted an aftermarket aerial to the car, and so I replaced this with a new Hirschman electric aerial (the supplier for BMW cars in the 1980s), with the correct shadowline mast. This is all still available online from Hirschman, and is the same as the original E30 aerial (they were the supplier for BMW). One part which is no longer made is the shadowline cap and mounting nut for the aerial - you can only buy chrome ones. So, i bought a chrome one and will have it re-coated black. For now though, I fitted the rubber type fitting with ball top, which was also an option on E30s from new (but not fitted as standard to 325i Sports). For reference, the aerial masts are identical for both the nut and the ball type fittings, so they are interchangeable. Whilst in the boot and with the carpets out, I gave it a good wash and check for rust. This is the first sport I have seen with no rust whatsoever in the boot - the rust coloured marks in the pictures are in fact waxoyl, which has been sprayed in. I fitted some Z3 top mount reinforcement plates, and new top mounts and gaskets. The spare wheel is brand new, never used!
These are the part numbers of the Z3 plates if helpful for anybody:

During the early 1990s the owner had an aftermarket alarm fitted, which had long ago stopped working, and I didn’t even have the fob for it. I decided to remove it, and thankfully it was only spliced into the car loom in four places, despite all the wiring below. Some wires were not attached to anything at either end! I wrapped the splices and then wrapped the loom in cloth loom tape. The car will have my own security fitted, which wont involve splicing wires or messing things up.
Next up was the interior. When the car was almost new, the first owner had the parcel shelf speakers upgraded to larger ones, and cut the parcel shelf to fit them in. It was a fair job, but not original, and I wanted to put the car back to OEM. So I hunted for a parcel shelf in comparable un-faded condition, and managed to find one which had been in storage for many years, and had the optional extra rear blind and premium speaker upgrade. You can see side by side with the original shelf that the colour match and condition is pretty much identical. I also bought new clips and hooks (still available from BMW). The shelf itself is still available too, but on back order, and the one I bought from them a few years ago was not the same colour as the originals, so you're perhaps best off hunting for a good original one.

When they fitted the larger speakers in the rear shelf, the previous owner also chopped holes in the front door cards, ruining them. They left the original Blaupunkt head unit fitted though. Most door cards for sale have lifting vinyl or are damaged, and they went NLA a long time ago annoyingly. I haven't managed to find a good pair of cloth anthracite front cards yet, but I did already have a perfect set of black vinyl cards from a car with about 30k miles, so fitted these for now. I'll swap back to the correct anthracite door cards when I can find some, but I quite like the look with the black vinyl ones for now! I was going to re-waxoyl the rear aches, but they didn't need doing.

Given I had fitted the premium rear speakers, I also bought the tweeter speakers for the front which would be part of the optional upgrade when the car was new. They are now NLA, but I found some new old stock. Looking on Real OEM it looks like they might be available from the dealer again now though. I have not fitted them yet though.
I decided to fit the factory option of heated seats, starting with fitting the loom under the carpet. The looms are now NLA, but I found a new old stock loom in Germany. The rest of the kit is still available new from BMW, and so I bought new heating elements, switches and the fittings to mount the loom plugs under the seats. Easy to put back to standard spec for this specific car if wanted, as the loom simply plugs in behind the glove box, to a socket already there on all E30s.

Heated seat loom threaded in the correct 'loops' along with the main body loom:
To fit the heating elements, the front seats have to be taken apart into the base and back sections, and the backrest and base covers unclipped at the ends. No staples etc have to be disturbed, as I have found that using a flexible ruler the elements can simply be slotted into the correct place, as below.

The car's front seatbelt buckles had faded a bit, so I swapped them for a pair which were bought new not long ago, and barely used. The seat runners had also rusted as they often do, and after calling BMW and finding out that a new set is now just shy of £2k (yes, for 4 seat runners!), I found a pair of new old stock ones, and a pair of excellent 'as new' ones. It was also a good opportunity to clean and re-grease the seat mechanisms, which attract dirt over the years.
Looking at the car's service history, in 1989 the first owner bought a rear console with tape deck and fitted it. I decided to put the car back to original, and bought a new rear console without the tape deck, which is still available from BMW. Unlike the new dashboards which look nowhere near as nice as the original ones, the console finish is pretty much identical to the original. I cut holes in the new console for the heated seat switches - there are marks on the inside telling you where to cut. The car originally had the rubber boot around the handbrake gaiter which I think looks a bit rubbish, so I bought a new OEM BMW leather handbrake gaiter.
A few years ago this car passed through the hands of a dealer, (and I believe it was them!) who sprayed dashboard shine over all of the plastic items in the interior, because shiny is apparently good. I spent a long time removing all the trim and cleaning it gently with mild soapy water to get it back to the nice matt finish, and refitted it all.

I bought a new all in one gear knob and gaiter, the same as the original one, but the illuminated version. The illuminated knob has a small additional loom to provide the power, although the one I received from BMW would involve cutting into the car's loom which I didn't want to do. The original looms for these did not involve any cutting and simply plugged into the rear ashtray light bulb, so I used one of the original looms.

I also decided to fit a boot liner trim, which were standard on 325i SE cars, and an option on all other E30s, except M3s. Not original to this car, but easily unclipped. These are still available from BMW, and at about £180 are cheaper than some of the used ones sell for on ebay. The clips are available still too (you need 14 of them). I think this trim makes the boot look a bit more finished.
The car was fitted with modern M badges when I bought it, which came straight off! I bought some correct E30 ones from the dealers, but have not fitted them yet. I'm sure this will divide opinions though!
The few optional extras I've fitted could easily be removed and leave no mark, but I really like a nicely specced E30 and think it was worth adding them. One thing I've decided not to add is air-con, because it's quite involved (I've retrofitted it to 4 E30s) and would involve me messing around with this original car more than I want to. I am going to fit cruise control too, and have collected most of the parts ready for this, but than can be a project for a spare day in 2019.
Mechanically the car is excellent, and following the work carried out prior to me buying it, and the new complete fuel system I have fitted, it's been running perfectly. It did initially hunt on idle a bit, so I looked it over and couldn’t find an air leak, and the ICV looks recently replaced. I had a garage re-set the parameters, and it's been fine since.
That's where I am at now, and I plan to do a few more bits and pieces to the car, but predominantly just look after it and enjoy driving it now and then on sunny days!

Some the pictures above are not in the order I did the work, so it may not flow perfectly! There's lot of other things I have done and not mentioned, but I'll be posting updates of the next work over Christmas too.
When I did the rear top mounts I gave the boot a good clean out too:

Lovely car, well done.
Do you have the part numbers for the OEM exhaust you fitted, please.
I am struggling to find one where the rear pipes exit straight like yours (instead of diagonally).
Thanks
Ben

Hi mate - looks super - i love it that you keeping it oem as possible!
In regards to the fuel tank, i found the following on real oem:
https://www.realoem.com/bmw/enUS/showpa ... Id=16_0218
This says it 55 litres
When I checked on gsf, it says 63 litres?
https://www.gsfcarparts.com/293bm0020
Anyone know if the gsf one is correct?

Wonderful car! The E30 is truly my dream car, and I am currently saving up to buy one, (I’m 17). I am a bit worried about all the work that probably has to be done to it, because I have only recently started working on a Saab, but that is why this forum exists, to help others! Really nice work!

Thanks very much for the comments guys. I’ve done a few more things to the car over the last seven months - I can’t believe it was Christmas when I last posted on the thread! I plan to add a proper update next weekend.
BenHar - I’m afraid i don’t have the exhaust part number. The exhaust came with the car when I bought it, and was purchased by the previous owner and already had the stickers removed. They are still available though so hopefully the dealer can help (although you’ve no doubt already sorted it).
jojjo132 - Thanks, and you’ll find pretty much any answer you need on this forum. I bought my first E30 at about your age and learnt so much from the technical help section on here.

I thought I’d post an update for the last 8 months...
Something else I wanted to retrofit was cruise control. I bought a used kit for the ECU and actuator (these are on back order at BMW with no expected due date), bought a new old stock control stalk (these are now NLA), and most of the rest of the kit is still available new from BMW. I’ve included the part numbers in this pic for anybody else retrofitting this. The loom is now only available in RHD and I think few are left.
One part which is NLA and I couldn’t find anywhere is the little bracket which goes on top of the suspension turret to hold the cable. I eventually got one posted from a breaker in the US.
The actuator isn’t available new, but the cable and mounting bracket are. The cable simply unclips from the actuator so is easy to swap, although I took the actuator apart as well and checked and re-greased the gears.
I fitted the new loom in the correct loop holes inside the dashboard so it looks factory fitted.

Manual cars require a clutch switch so that the engine does not rev too highly when the clutch is depressed with the cruise switched on. Buy the bracket from BMW, but the switch itself is far cheaper to buy from suppliers other than BMW, and Febi make the OEM switches.
Cruise ECU mounted in the correct place above the glovebox
Installed in the engine bay. I also fitted a new fuse box lid as the original had the tab broken off. These are still available new, but are a bit hit and miss with how well they fit.

The front footwell speakers were missing due to the aftermarket ones somebody had fitted in the doors, and I decided not to fit the new tweeters I had bought and instead just keep the car stock with the original stereo loom. You can still buy the BMW premium sound system speakers which are used in conjunction with the tweeter pods new, but not any of the standard front speakers. So I opted for some Audison APX5 13cm speakers, after seeing good reviews. I’d recommend them too - great sound and perfect flush fit for the E30.
The headunit and associated wiring is the original dealer fit setup, and I tidied this up with heat-shrink on the joins and reconnected the electric aerial wires which had been unplugged when the aftermarket aerial had been fitted.
The under dash panel had a piece broken out of the top front, and so I bought a new one from BMW. These are now only available without the OBC gong hole, however there are marks on the inside of these showing you where to cut, and with some measuring from the old one too I replicated the hole.

Early Tech II sports like this one were fitted from new with a 385mm Tech I steering wheel. I personally think the Tech II looks far better and is more in keeping with a Tech II sport, so purchased a new 370mm OEM wheel. I tried the dealers but they are NLA, however for anybody interested there is still one dealer in the U.K. with one left on the shelf, although without the centre/horn push (i can pass on their details if wanted). I sourced mine from a seller in Germany, who was selling a couple of new old stock wheels. The original Tech I steering wheel is stashed with the few other parts I have swapped, so can be swapped back to stock if wanted to.
A nice little find was this storage tray for the boot, to sit on top of the battery cover, complete with warning triangle, wheel chock and first aid kit. Another part not for sale from BMW for years, but they crop up on eBay.
I fitted the OEM E30 M grill badge I bought, which I personally like, but left the boot one off.

Having fitted the new heating elements into the original sport cloth interior last Christmas, I was pulled two ways when Barry (bss325i) contacted me to say he had a set of black leather sport seats from a low miles late 325i Sport for sale. I decided to buy them and to carefully store the original seats from this sport along with the original steering wheel. Easy to swap back, but I prefer the leather...
So it was a case of another set of new heating elements from BMW, dismantling the seats and fitting them in the same way as with the cloth seats, keeping it all looking factory. Good job I enjoy fitting elements!

I gave the leather a thorough deep clean with leather cleaner whilst the seats were apart, and then used leather conditioner on them. Over time I’ve found the best method to look after leather is: hoover the seats, especially around stitching, clean with Gliptone leather cleaner and warm water, condition with Gliptone leather conditioner, leave for a few weeks and then clean again lightly with leather cleaner. This is because the conditioner can actually cause dirt to stick to the seats if not washed off the surface later as even after it has ‘soaked in’ as much as it can (which even on 1980s car seats isn’t a lot as the leather has coatings on it which stop it penetrating much, and on anything mid 1990s onwards leather conditioner doesn’t penetrate the PU finish at all!) it leaves a greasy residue.
The seats were near perfect, with the only imperfections being some splits in the plastic piping on the driver’s seat outer bolsters.
I hunted for some passenger seat inside bolsters (these are the same as driver seat outer bolsters) to swap these with, and ended up buying a complete passenger seat which somebody had stored in their house since the early 2000s, and was in excellent condition. The leather was a perfect match, and I copied the factory hog ring pattern when swapping them over so it’s indistinguishable from having being built in the factory. Bolsters should always be swapped with the foam inserts too, as they are all very slightly different after 30 years, especially the outer side ones which wear.
