Just a little update.
1) Engine is almost ready to be removed from the saab.
2) been speaking to the guys on www.uksaabs.co.uk , where my thread has been made a sticky
And a spec has been made for up for maxium performance for minimium cost.
1) Remove current turbo and send it to Universal turbos. Ask them to fit either an 18T or 19T compressor wheel. The 18T should scrape 350 on a very good day.... 19T guarantees and is more likely 370bhp
Ask them to take 10deg clip on the turbine wheel to get high rpm flow up. 18T is more point and squirt though and won't get caught off boost so easily.
This should cost £500 tops.
2) Source some green giant injectors 430cc (0280155968). Geniune Saab in the US have them for £175 for 4.
3) Get a 3bar map sensor (£40) This is a GM part - don't have number handy.
4) Ensure your exhaust and intake are nicely free flowing and your I/C is good.
ECU wise somebody has offered to flash there map (designed for the above spec) on to my ecu for £50 + mail me the bin file for the stage 3 map which is already on there.
They are very helpful and although the map won't be perfect it should be very close.
http://trionic.mobixs.eu/
using the above program the cu can be further modified.
With 350bhp and a 1000kg e30 she should be very likely.

Hi All, Just a little update of the progress i have made since last time i posted. Although it might not seem much, motivation has been low and with it being soooo cold staying outside allday is always a challenge.
Here goes
The first step was to remve the lump from the saab, i decided to do this with as much attached as possible to help when installing it into the e30


The next stage was to find the GM omega gearbox, I contacted Megavaux and £80 (including postage) later it arrived. This is the big worry on the build, as the GM gearbox is rated at 280nm and in tsandard form the saab b234r makes 325nm, with the current spec its getting on 400nm. I'm hoping theres a large safety factor in the GM figure. However I'm going to purchase a second box and have it cryogenically treated to allow for future turbo and boost upgrades.
Check out this link for the explanations
http://www.cryogenicsinternational.com/

Following this i stripped anything of value on the Saab and sent her to the race track in the sky(scrap value is now at its lowest so the £100 i thought i was going to get never materialised)

Gearbox and engine bolted together ready for the test fit

While the engine was out i measured up the mounting points on the block and made some dummy plates from 2mm aluminium for a test fit.


These were then measured and drawn on solidworks. the working drawings where then sent to be my former place of work and machined for free

With this done the engine counld now be positioned int the engine bay. It was decided that the engine was to be loctaed central to the car with anough room to get to the bellhousing bolts incase a gearbox change was required
, I think a little manipulating of the tunnel may be required for the shifter tho.

Bloks of wood/ axle stands and jacks were used to hold the engine in place until the mounts were welded

With the engine positioned I friend (with 20years of welding experience) came round to weld the mounts up.


Engine is now bolted in place
and ready for radiator +exhaust fabrication etc etc. Once this is done i will remove it all and give it a freshen up + new clutch etc etc



Mean while Iv Started work on the interior, The dash panel has been started and the door cards are finished. Iv also started countinued work on the loom and have decided to use CBS fuse box and simply cut what is needed from the bmw loom and wire straight to this.

Although it is not finished and needs tidying, the plan is to copy the old Group A M3 dash layout and then get all of the aluminium panels powder coated plack.
Currently i have no real pictures of loom work but just imagine a plate of spagetti and your half way there
Thats all for now

What an unusual project! My hat's off to you mate. Has anyone ever dropped a Saab engine into an E30 before?

It felt bloody quick on the way home. Your right tho the shell was a proper dog, when i removed the abbott rear suspension (to sell back to the guy i bought the car from) the rear macpherson struts were being held on with iron oxide
god knows how long it had left when being used hard on track.
Cheers for all the positive comments guys, its good to know i haven't got loads of purists saying
'how dare you put a saab engine into a BMW'
I guess its better than a pinto tho

Rosscoe: Its a 6 point omp cage, the rear brace was very straight forward,i simply measured the gap turned a lenght of 50mm bar down on a lathe to ensure flat faces, then cut the end platesand weled them to the bar.
The diff pick up reinforcement was alot trickier tho.
Malaise: My original aim was last summer, however i should have it done for my annual trip to the nurburgring this summer.
cheers

Liking the project so far
Do you have the details for the diff reinforment?
I'll have to do something similar in the near future and any info would help greatly

No, but you wouldnt be the first to think that... A most unfortunate clash of engine naming, it has to be said. The SAAB B234 was a hugely advance engine when it came out and is still a force to be reckoned with. High flowing heads, strong conrods, chain driven and the ECU (Trionic 5) is supposed to be the envy of Bosch etc.. From what I read when I had one, 400hp+ on stock internals is quite doable (but not necessarily cheap...).Aramil wrote:So is this the B234T engine as found in the Volvos?
Maptun have some 600hp + 9000s in sweden I believe?

what sort of details are you after? I have all of the solidworks files for measurements etc and have pictures of every stage but basicly,
1) Removed the original hanger
2) Bolted the diff with e36 back plate to cross member and using measurements of differential angle from before positioned it with a jack
3)Bolted the fabricated brackets to the diff and tacked them in place
4) Cut small grooves either side of the pickup points through the floor and double skin inside the car
5)Tack the double skin floor in place
6) place the horse shoe bracets through the grooves and tack inside the car and on the pickup points
7)Weld every thing up
8 ) Weld rear strut brace in and cross braces onto diff pick up points.
To be honest it was a very involved process and deemed nesessary when i had a big power target with the m20 turbo but now it probably is n't really required. However with the current setup I'm happy in the knowledge that the rear end can pretty much take any increase in power/torque i plan in the future.

Hi All , its been a long time coming buts here is a small update.
First up was to fabricate the gear box mount and linkage.
I started by positioning the gearbox and engine assembly level with the chassis using a jack.
From here i fabbed a bracket using the BMW as a base.

By oldroyd, shot with

Once i was happy with the position , i made sum additional supports and had it welded up.


And added a coat of paint

Initally I used the Ireland engineering gearbox mounts to mock up the mount, however the omega box uses an M10 thread and the BMW ones are M8, as a result i ordered a bar of 'race' stiffness polyurethane and made a set with some M10 bar running through it.




Finished

Following this the aim was to get the gear linkage sitting in the centre of the tunnel and the original lever hole provided by BMW.
The standard position was approximately 20mm out so i started modifying all the components to suit.


The end of the bracket also required shortening.

The below pic is the standard linkage.

Cut line added

cut

Now sitting central to the bracket and tunnel.

The next stage was to get the gear lever mechanism sorted, this is the scary point and i was a bit pissed off when i realised i had to cut the transmission tunnel after I had just painted the interior.
Using omega gaitor as a template




Install, omega metal surround to add strength back into the tunnel.



Coat of paint and a test fit with the linkage.


Now, today I have taken the plunge to BIN the omega gearbox idea !! As a result all this hard work was a waste of time. I Have decided to go for a T5 cosworth gearbox and use a custom bellhousing, the reasoning being that I have no confidence in the strength of the omega box and following a chat with some of the guys on drift works decided this was the best option. I
Its no fun driving a car you think you are going to break when used hard.
As a result if any one wants an E30 - omega gearbox mount and linkage just send me a PM.
The new way is way more expensive but I'm sure the end result will be worth it!!
While this was going on I started building up the shell.
Added the dash , front roll cage, buckets seats, hydraulic hand break , harness mounting points, Lights and window rubbers.






Ive also been playing with an ali dash panel, where i plan to install a Stack (or similar (cheaper) ) digital dash.

Here are my custom lights.
I basiclly only want the outer lights but also want to be road legal. I'm making a wiring loom from scratch so the wiring wasn't an issue. I bought a pair of universal 5.75 inch headlamps, with side and dipped built and using the standard bmw bracket had a play.

The plan is to smoke them but currently this isn't at the top of the huge job list.
Harness points


Finally.
Ive also mocked up the sump in cardboard (Lap top broken so no more Solidworks) to get the required measurements for sump. Its now with Altiss engineering
http://www.altiss.com/
along with the inlet manifold fo get the required mods.
Left over of sump to clear the cross member.


Did a few calculations to achieve the correct volume and started my art attack.



Should be finished in a few weeks.
Currently I'm having a packaging nightmare with the turbo around the block, engine mounts and servo /mc. It looks like a custom exhaust manifold is required.
Heres a pic of the car when i was playing with the ride height. (I think it needs to go lower)


Thats all folks.
I'll update again when I've sorted the sump and turbo and deep into the second gearbox installation.

thats a cracking job. one of my favourite projects.that paintworks quality, as is the workmanship your puting into the whole project.almost makes me want to reconsider breaking mine up...but not quite.
co incidently i have a t5 box up for sale if your looking for one.

Fuzzy, I may well be interested.
What sort of price are we looking at ? and what sort of condition?
Also interested in your fuel pump.

Can't believe I've only just discovered this thread! Epic stuff.
Sounds like you were in Swansea at the same time as me - I'm guessing you could have been Automotive/Motorsport Engineering at the Institute bearing in mind your obvious skills? Small world, though as I was doing English I doubt our paths would have crossed all that readily.
