E30 Track Car Build

Hi, i thought i would start a new thread in the correct section to keep all the pictures and updates in one place for my track car build. As you know, last week i purchased this car...
Unfortunately having now realised the shell will not be up to the task, i set about finding a replacement shell. Some of the parts the 1st car came with will be put to good use, some sold, the rest scraped
Today, the new shell arrived which i have been very kindly donated for the project. A mighty fine manual 316
This now means my original plans have been hugely changed, as you can see i have a lot of work to do. Ther car will recieve a full strip down, paint and rebuild. My plans were to install the 325i lump from the 1st car, which may well still happen. However i have a real urge to install an M52 328i. With the lengths i will be going to, to get the car how i want, i really dont want to have to be redoing tasks later down the line so some carefull planning will be needed.
I know i will have a huge amount of questions along the way for you guys. The forum seems to be a wealth of information and i'll look forward to sharing this project with you. My profession is a car detailer by trade, so i will do my best to get involved within your detailing section and try to advise with any questions you have on keeping your E30 looking tip top.

Thanks mate, sorry to hear about the garage burning down!

Best of luck fella! The first shell a bit rusty?
Keep us posted, look at my car build - for top tips on how not to do things!

Hi mate, i knew it needed some welding and jad some rust, but i just wasnt happy with its structure once on the ramps. After some enquiring, this 2 door came up which seemed a much better alternative as a base shell.

Started gutting it today. Seats, door cards, roof lining, centre console, stereo, carpet, seat belts, loads of random bits here and there and all inside the boot. Dash will be next. Would have been quite a lot of weight out of it. Will get some pics up shortly.

I have been reading lots about suspension and handling setups for track use, planning what i will need when the time comes. The GAZ Gold kits, with the uprated top rear mounts seem a nice bit of kit. I have GAZ shocks, although not quite as good as what these seem on my TVR and they have been great, although they came with the car so i cannot compare them to anything else. I will also use front are rear strut braces and an uprated arb kit. I have seen these by Eibach and H&R. Are there any differences between the 2 arb kits?
How does this setup sound for track use? Bearing in mind i am not interested in any competion style of track days, just fun days out

Can you recommend any others that may suit if this sounds over kill?
Cheers

Isn't the picture I took at the top of the homepage this car before it had the wheels fitted and some tidying up?

Few more pics with todays progress...
Dash stripped out
Started stripping the rear end
Removed a load of parts in the engine bay and started disconnecting pipes from the old 1.6
Everything being labelled up and bagged along the way
Removed all the bits to get the rear quarter glass out, but am struggling to get them out. The guides say they should be very easy, does anyone have any tips to save me from damaging them?

Would be interesting to see how much that lot weighs, good effort
Re:

I havent weighed anything along the way but i will certainly weigh the car once its finished. If i can get it around 1000kg that would be great, if thats do-able?

Today i picked up a racing dynamics front strut brace, a rear eibach anti roll bar and a 3.64 diff.
There is a plaque on the diff that says 3.64, but it did not have an 'S' before it, i thought all the lsd's had the 'S'
It was sold as an lsd and i opened it up at work, and everyone agreed it was.
Does this sound correct? and will this be a suitable diff for the track?

Bit of a long ratio for an M20 engine, most favour the 4.10 ratio
But, its a good ratio for an M52 with the matching E36 box

So you think it will be an lsd, even though it doesnt have the s on the plaque?

Pics stolen from google here:
Open diff:

The cases are slightly different here as one is from an E21 however the internals are the important bit.

That's a slipper
I moved my car (pushed) yesterday and I was amazed even shunting it about how much better the E46 rack is

cheers mate, glad thats ok then. Will the 3.64 be ok for track for now? Even if i look to change it later down the line
Looking forward to fitting e 46 bits, not that i've ever driven this car lol but have owned a 325 sport before many years ago

Not many updates lately, but the e46 rack arrived this week as did DanThe's kit. Looks very well made and promptly shipped, cheers
Fairly soon i will transfer both cars to my work to get the mechanical work started, which is a fair bit
One question i have, the loom in the 316 shell (which is the one i will be using) compared to the loom in the 325 car (which is the engine i will be fitting) - are they different at all, should i fit the 325 loom?
Thanks,
Christian

I believe there's some info on the wiki about converting the 4pot chassis loom to work with the 6pot engine loom, Brianmoooooooooore will be able to point you in the right direction if there isn't. That said if you're starting from scratch then fitting the 325 chassis loom to the new car kind of eliminates the chance of anything being done wrong when adapting the looms if that makes sense. It will also give you a good chance to lighten the chassis loom and get rid of the bits that aren't needed.

You dont need to swap the looms, for what you need they are the same, you might need to change/adapt the rear plug in section for the fuel pumps/diff sensor depending on what you already have.
Just make sure you remove the earth wire from pin 20 of the C101 before connecting an engine loom

Cheers for the info on the looms guys.
I have another question regarding the gearbox. My 2.5 engine currently has a 1.8 gearbox fitted. With the 3.64 lsd i have purchased, will this setup work or should i really purchase a 325 gearbox. How will acceleration and top speeds be affected either way. I will be sticking with 15" wheels if this makes a difference.
Thanks

Anyone have any comments on the gearbox query?

Hi guys, couple of queries as i am planning to get the bulk of the engine swap completed over the xmas period. So i have to remove a 1.6 lump from the to be track car, remove the 2.5 from the donor car and refit to the track car.
Still wondering if the 1.8 gearbox which is currently fitted to the 2.5 will be good for me to use i should i purchase a 2.5 gearbox? Will be using a 3.64 lsd if that makes a difference.
Will i need to swap the subframes over front and rear, is there a difference? I know the shocks will be the smaller diameter type but as i will be fitting coilovers, will this matter?
Hope this makes sense, just want to know where i am before the day comes
Thanks

Tbh I'd be getting a 2.5 box it saves have problems with mixing and matching parts when it's not necessary.
Subframes are the same so chose the best and use them.
M20 will use 51mm front struts so use those.
