Hi guys,i thought id take some time and take some photos and explain a bit about the conversion i've done.


The engine :
3.2 evo engine + 6 speed gearbox ,55k miles ,one not so carefull owner ! thats why i got it.
I had removed the engine and box from the e36 the day before.

Image


Old engine out :

Image


Dropped it in but didnt realise at the time id need a 5 series sump ! :mad:

Image

Sump hitting the crossmember :

Image

So new pump was needed as the evo one wont work with the 5 series sump.An m50 one was used.
the 5 series sump i recieved a week later from quarry :

Image

Had to remove this baffle thing to fit it,also the oil pump braket for the evo pump needed to be removed from number 5 main bearing cap. :

Image

Engine in !! :

Image

Image

Image

After that the radiator and pipe mods were done to pipe everything up like fuel pipes , heater and coolant etc

Now the electrics :

Ian Haynes supplied me with full wiring instructions and was very easy to follow.The EWS 2 is all wired in also :


Image

Lots of crimping and soldering later and all was done.

I also decided i didnt like the e36 wiring box so i fitted a e30 4 cylinder cover and crammed all the wiring into it. Looks nice and neat,and factory looking.

Image

The prop was shortened and had the e36 part welded on at reco prop,cost about £100.Also i made my own custom gearbox mount to hold it in there as there isnt one that can be used.

Then the next major and probably the hardest part of this conversion the plenum to servo clearance.Basically there is none ! the standard servo wont fit so i fitted an 1.3 MK2 golf servo but it was still hitting so i removed a 2" long by 1" wide piece out of the corner of the plenum.And it fit ! Only problem now i needed a master cylinder to fit,and be shorter than the e30 one as it would hit the intake boot on the plenum chamber so and audi one was found to fit.It fits straight to the golf servo with no mods.As i will be upgrading to bigger calipers on the front i have fitted a 25mm audi mastercylinder instead of the 23mm,which is same size as the stock e30 one.
Heres a pic :

Image

It fits but the brake lines needed remaking to reach,also note that the intake boot still looks very close and wont fit on. :banghead:

Image

So I decided to move the servo over on the bulkhead 0.5" to make some clearance.
Re drilled it all and made the servo fit ,half an inch over.Nice one i thought but then the lever on the inside wouldn't connect to the servo.
So i extended it and re-drilled it.

Image

This worked a treat.

I then seen a carbon fibre plenum on ebay! so i had to have it.
I thought it would fit as i had seen an s50 converted e30 on e30.de so i bought it.It didnt fit :cry: £500 wasted.But then i came up with the idea of shortening the trumpets and putting samco hose inbetween, so heres what it looked like :

Image

Image

Image

So nice one back on track i thought but i couldn't fit the MAF sensor in and i was unhappy with the quality of the trumpets so off it came again and i decided to TiG the old plenum up and fit that.
I may try and remake the trumpets in aluminium and ditch the maf sensor so that i can justify the £500 chunk of carbon fiber sat next to me now on my desk,but later .I want to get this on the road now !

I thought now would be a good idea to convert to an e36 steering rack instead of the crappy e30 one so i did this now before the exhaust manifolds are done.
Got a rack off ebay,pipes off Ian Haynes and made the column joint myslef.

Image

Image

Fuel pump needed changing for an evo one.

Image
Its a tight squeeze but it fits.I fitted rubber around it after i took the pic to make it sound quieter.

A couple of the inside of the car :

Image


Image

Heres a couple of pictures of where im up to now which is all done appart from the exhaust :

Image

Image

Image

Image

Image

Heres the clearance at the servo to plenum chamber :

Image

Image

Image

If it hits then i will just solid mount the engine,but i dont think it will.

The exhaust manifolds are being modded now by someone i know,then i will complete the rest of the exhaust system.I have bought an evo back box but its bloody heavy and a bit too big so will need modding to fit so i may not use it yet.

So to sum it up,theres the exhaust to do and then off for the MoT.
I will paint the cam cover the same as i have the plenunm in that wrinkle paint but im waiting until the exhaust manifolds are on so i dont chip the paint !
I also need to re route the oil cooler as its just cable tied to the bottom of the rad for now but i will move it to where iot needs to be when its on the road.

Many thanks to Ian Haynes and all the other people on here who have helped me.

Sorry about the maaaassssive post !
Comments,questions guys and girls,

cheers

Whats the pipe on the front of your rack here? And hows the fit inbetween the rack and sump mate?

Could do with something similar for mine 8)

Nice work Andy. Glad to see it's all coming together :thumb:

That's a standard 6 cylinder E36 return line (feeds fluid back to the reservoir). It's a bit deceptive in that picture, but most of the pipe sits more under the rack than between the rack and the sump. It is still close and you do need to 'tweak' it slightly to allow it to fit without touching the sump. It's just a case of squeezing it with your hands so it bends a little closer to the rack though.

Ian.

Hi guys,thanks for the great comments its been a tough job.A lot of credit should go to Ian for all the info he has given me on this im just the one who put it all together :D
There are many jobs that need doing on the conversion and sometimes a rethink is needed on how to get around the problems,now that I have nearly done the conversion i dont think i would do another but i think if i did it would be a lot easier second time round,also a garage would be nice to do it in as its the weather thats kept me from working ,especially over winter.

very impressive!!! this will be a rocket! you considered the alpha-n chip kits that people have been trying of late in order to run the CF plenum? other things that I've seen done include separating the MAF innards from the plastic casing and attaching it to the entry of the plenum/intake boot. like you say would be a shame not to use the CF plenum, it would prob make an awesome noise!

Tim,

Using Alpha N on the 3.2 Evo engine is a very expensive business as you need to fork out the best part of 4k for a Motec system to run the Vanos. It is possible to lock the Vanos in one position, but you end up loosing all the bottom end torque that the Vanos was designed for.

You can remove the MAF sensor from it's tube, but you need to be careful doing this as well. The MAF is calibrated to work in a specific sized tube with known flow characteristics. If you are not careful it will be giving incorrect values back to the ECU. I guess you could have a mapping session to correct for this, but it's something to watch for.

Cheers,

Ian.

agreed about the intake tube. in fact he could use an SMT or similar to deal with any difference in readings which would open up a load of doors while at it, using MAP or ability to run any MAF he likes (like a really narrow one!) for instance.
as for the MAFless stuff, didn't pay attention to whether it was a 3l or a 3.2 :oops: , and knowing that a lot of racers etc ditch the MAF on the 3.0s cars, and that people have had success with the plug-in chips on the motronic getting rid of the MAF I thought that might be an easy way out.
nonetheless, i've heard of people running MSS50 without the MAF. i know not that many places can do MSS50 tuning in the UK, but there are a few.

£4k for motec, ouch! don't other brands like autronic/siastuning/tec3 do full dual vanos control much much cheaper than £4k?

a bit (alright, massively!) offtopic and a bit of a long shot but ian you don't happen to know the length and full specs etc of the s50b30 and b32 intake valves do you? obv i'm aware of stem dia and head dia, but am interested in legth etc. i'm gonna have to try to get one of each 2nd hand i think, they're £50 or so each off BM.

i was thinking of alpha N but i didnt realise i would have to ditch the motronic.
I thought it was a piggyback ecu like a unichip.
I did think of putting the maf innerds into the carbon box,didnt realise that the tube effected the sensor.
If i just cut the 2 lugs off the MAF then i think it could be slid into the end of the carbon box.This would mean its in the box and therefore fit in the bay and also still in its tube.Only problem then would be i still cant get the filter on !

Heres a picture of the lack of space with it in place.Sorry its a bit blurry :

Even if i move the cruise control (infact i have now) theres still not enough room.


The ABS unit gets in the way also.

Hey Buster, got my car back on Friday, looking great with the rims and exhaust done. Started her up and OMG major bottom end banging!! :cry:

Having a look at your pics up in this thread you said you removed the baffle from the new sump. I don't think I did this so I'm hoping this is what's causing the noise. :roll: If not is something major! :cry:

I'm gonna try to get the sump off today or tomorrow but id doesnt look easy when its in the car.

Cheers Andy, I was just gonna ask whats the easiest way to do it.

Got all the bolts out but the sump aint coming out. I'll try to get it up on a ramp tomorrow night and do as you suggest.

I hope its the baffle too or it will be expensive! :cry:

sandy,i fitted my new sump with the engine in.I just jacked it up off the mounts , so no need to remove the crossmember.I hope it isnt anything bad !!
I had to remove that baffle for it to fit so surely when you put it on, it wouldnt have gone on so i hope its nothing bad.
