BMW E30 SR20DET



Well, thought I would but a bit of a thread up about the new project considering some members seem interested/keep asking. Quite a number of you saw my previous car on here (http://www.cliosport.net/forum/show...Car-Project-Year-3-Engine-and-Chassis-Rebuild), at track days or elsewhere - Eventually got bored even though it was a very fun, quick and solid car. Got a fair whack of money back in parts and the shell went to good use (hill climb) so happy days.

Continuing on from that, I wanted to build something a bit more 'custom'. I've had a few E30's in the past, so knew the common places for rust/problems with them etc. I'd seen a few other people who had done DIY 325i Turbo conversions and got good results, but I didn't want a heavy BMW lump up front.

Spent some time looking for a solid shell without a sunroof, then heard of a LHD one local to me which was still french registered and had the M-Tec2 kit fitted. Went for a look at it and it was solid, no rust whatsoever and a sought after engine (318is). I had a good think and eventually decided to buy it even if it was LHD, something different and unique for a start.

Picked it up a couple of weeks ago and stripped it down to a shell the same weekend...

As mentioned earlier I didn't want to go with a BMW engine and a home brew turbo conversion. I knew the SR20DET had been done before but not much, nothing was really documented anywhere and only a few very vague project threads. The info wasn't really there but it didn't put me off as I wanted something that would need some thought putting into! I decided to look for an engine and picked one up that had been removed from a fresh import S15 on 30,000kms.

At the same time I picked up a GReddy Profec II Boost Controller, Remote Oil Filter Kit and a couple of other bits. I didn't want to run the S15 box as it is 6spd, not to mention it being a lot longer. I sourced an S14 box with quick shift and a few other bits. I will need to change the S15 flywheel for the thinner S14 item to allow me to run the box. In the meantime I had picked up a 3.73 BMW LSD to use with the 5spd Nissan box.

The priority was to get the engine sat in place and mounts made up so I could see how it sat. I had a couple of days of research to get an idea but got nowhere really. After a bit of reading I decided on using some Land Rover V8 rubbers for the bottom of the mounts - readily available, dirt cheap and very stiff.

20110924134203.jpg


These were bolted to the E30 chassis as so..

20110924133758.jpg


20110924134811.jpg


20110924134821.jpg


Removed the S15 flywheel before fitting the S14 box for trial fitting..

20110924132128.jpg


20110924133731.jpg


20110924132118.jpg


Then lifted the SR20 into place..

Before making the engine mounts I wanted to get the gearbox mount out of the way. It consists of a Nissan gearbox rubber and the standard E30 transmission mount.

20110924145037.jpg


Marked out the center of the transmission mount and drilled the holes for the rubber..

20110924145533.jpg


20110924150111.jpg


This was then fitted to the box so the back end was mounted and the jack could be used to get the engine in the correct position instead of the crane. After looking at the mount once fitted I decided the transmission needed raising to bring the prop shaft up level - and more importantly clear the ARB. Two pieces of 5mm plate were welded to the E30 transmission mount to give it 10mm more height...

20110925124305.jpg


20110925124508.jpg


Resulting in a much better height. A quick check inside confirmed the engine/box were as far back as I could get them without cutting the exhaust tunnel up..

20110925142807.jpg


20110925142842.jpg


20110925142834.jpg


Then the real work could begin making the engine mounts - The engine could physically go back another inch to an inch and half as that's how much room is available between the bulkhead, but then I would run into issues with the gear shifter hole and sump hitting the steering rack. I was happy with the position so carried on.

Started with the passenger side mount first. Began with four pieces of 60mm square 5mm plate and drilled them to 10mm...

20110925142724.jpg


20110925144408.jpg


Then bolted them to the chassis and rubber on both sides..

20110925145007.jpg


Had a quick measure of the engine in the bay and got it to the correct height, along with being bang in the middle of the engine bay...

20110925145302.jpg


Next, used a piece of scrap to tack both plates together in the correct position so I could make the mount off the car..

20110925151129.jpg


20110925153128.jpg


Made plates for either side, then the back..

20110925161144.jpg


20110925161748.jpg


and bolted it upto the engine..

20110925170016.jpg


20110925170023.jpg


Checked the position of the engine once again and cracked on with the drivers side. Same method, tacked some scrap in..

20110926174530.jpg


Then some of this, and that..

20110926181654.jpg


20110926181842.jpg


Resulted in getting somewhere near..

20110926194127.jpg


Then the finished piece..

20110926203815.jpg


20110926203824.jpg


Bolted both sides up solid and let it down off the jack for the first time. The weight difference between this and the 318is seems to be quite a bit, as the front of the car has lowering springs on and its now higher than standard would be! Had a quick check of the steering rack and ARB clearances..

20110926203744.jpg


20110926204016.jpg


Its pretty close to the standard ARB (which is going to be significantly larger), and clears the steering rack nicely. Its about as low as it will go without modifying anything else, especially with how much clearance there is on the ARB! Looks about right :)

Looks mint, great engine/car combo. looking forward to the updates, am hoping to eventually own an e30 myself in the future.
 
Few bits from the other day. E30 Prop (Front Section) vs S14 Prop (Front Section)..

20110927174136.jpg


Chopped them up so they could be sleeved, then adjusted to length under the car and bolted a new center bearing up to be sure of the length..

20110927182913.jpg


20110927182942.jpg


Tacked it under the car then removed it to put a bit more weld on to hold it at the correct length..

20110927183721.jpg


20110927185252.jpg


Dropped it off at a local prop shaft manufacturer a few days ago so I should have a nice new prop at the correct length next week :)

After that I decided to make up a couple of lower radiator brackets. I am using the S14/S15 radiator as it fits perfectly between the chassis legs on the E30 (with about 5mm to spare either side!).

The standard BMW radiator mounts look like so..

20110928181041.jpg


20110928181034.jpg


20110928181050.jpg


So those were promptly chopped off and the lower metal cleaned up..

20110928184030.jpg


Bent a couple of brackets to shape in the vice..

20110928185335.jpg


20110928185915.jpg


Drilled them to the size of the S14/S15 radiator rubber and rounded the edges..

20110928191703.jpg


20110928192045.jpg


20110928192021.jpg


20110928192137.jpg


They sit on the radiator like..

20110928192240.jpg


20110928192245.jpg


Which I was happy with. So after a bit of messing I managed to get them tacked in the right place and then fully welded them on..

20110928200510.jpg


20110928200703.jpg


Then sat the radiator in place..

20110928201043.jpg


20110928201026.jpg


20110928201113.jpg


The lower hose from the S14/S15 fits perfectly, although I'l need to find one for the upper..

20110928201215.jpg


20110928201127.jpg


Then finished by undersealing the brackets..

20110928203003.jpg


The whole bay will be properly sorted and painted once I've got the bigger jobs out of the way. Still got to make a pair of upper radiator brackets over the next few days but nothing major!

Sweet Jord, good to see some of the work you've been telling us about, shame the cars about 40mins from mine lol!

If you havn't found an upper hose yet i have Loads of spare hoses, including that 172 lower hose i got that could maybe have the correct bend init that'd suit you? also got a few other random hoses, could bring them out tmoz all the 40mm(?) hoses i have for you to try if you want...

Il have to have a look, not in any rush just yet. Its got to be an S and drop height wise

Trailiered, I wouldn't have bought this one if I wanted it on the road, as its got no V5 and never been registered in the UK :)
 
I didn't get one with the engine but I had a feeling one my fit with a bit of 'adjustment', let me know if you come across it..

Cracked the back casing on the LSD earlier removing the old bush to replace with a poly, so I need to source a new back plate now sigh.

Ooooo about time you played around with something else - I'm afraid I'm going to require regular updates ;)
