Big ///M Motor...small car

[Raxe]

I basically ordered the biggest griffin radiator that would fit between the frame horns and cut to fit....and it works including a ac condenser and a 16in spal fan all under the stock valance and with the stock hood hinges

Interesting... not sure if the mechanical fan would clear that though.

His V8 is not as deep either, I know for a fact I'd have zero luck with a mechanical fan (or engine shift) with a radiator mounted in the stock location.

Nice choice of powerplant! Im currently doing the same thing, but in a tourer, and I`ve overcome the radiator and subframe problems with some other problems:D
For understanding the above, here`s a pic of my way of fiting the greatest engine in M history into the greatest body of all time:

More pics please! What mounts and how much firewall smashing? Can you still run the blower motor?

Helo from tacoma! i saw this parked on Jackson ave-Bridgeport over the summer on my way to chambers. Love the euro bumpers

I don't think you can run a standard heater core/box with the motor moved that far back. Don't get me wrong, for a dedicated track car with an S38, that's an amazing idea. Although, if you delete the center consoles and don't mind not having or completely re-engineering the heating system, it would be a great way to keep the weight a bit further back from the nose and give you plenty of clearance up front.

Then again, I'm not sure you need to have the engine quite that far back.

[EddyDevelopmenst]

OMG, this allmost looks like a thread hijac
To answer some questions:
-the weight of the mighty S38 is huge, so I`d rather position the engine where it has to be, and create a bunch of other fabricating problems. I love the E30, and I hope it drives really nice with this engine, Its gonna be a hard task to make everything neet and OE looking, but I`l do my best.

Motor mounts are custom, infact, everything is gonna be custom about this car, from the engine, oil pan, firewall, AC, the suspension and brakes and so on...
will open my own thread when I catch the time..

Sorry to get sidetracked.

Back to the OP. Looks great. Are you using E30de mounts or making your own? My engine looks about the same position as it is in your mocked up one. I also tried using the M5 boosted but it cannot fit beside the intake plenum. Did you have to mod the intake or did you move over the booster much?

Also, whats the diff you plan on running? I have a 3.73, 3.46 and a 3.25 but not sure what is going to work best for this engine. Although I am putting in a 265 instead of the 280 you are using (I am keeping a spare for my E34).

I'm running the 4.10 but will switch to 3.73 to better economy and longer first and second. I am using stock m3 265/5 tranny.

Can someone teach me what's excatly the difference between these two S38's? I mean in their stock / OEM form.:p

From a weak memory, the 3.6 makes about 25 less hp (310 vs 335). the 3.8 was never brought to the US. the 3.8 has slightly larger TBs, higher compression, more aggressive cams, but a heavier flywheel. Obviously .2L difference in displacement and torque is up 30 ft/lb over the 3.6's 266ft.lb. Performance in the e34 body was .4 seconds faster with the 3.8l. 3.8

3.8l is rumored to be a little more temperamental and the 3.6 is better to build up for a turbo. I only have experience with the 3.6 personally so can't give an opinion.

ZOMG S38.

As an owner of a car w/S38B38,, and a previous owner of an E34 M5 S38B36

i will say that the B36 is more .. agressive on idle,, that is , because of the single-mass flywheel .. the B38 is a lot more smooth ..

the torque in B38 is more in real life vs on paper,, in higher gear on low rev ,, the B36 is no competitor,,

If some one out-there is a S38B36 owner ,, i would recommend changing to single-mass flywheel ,, that include also the plate + pressure ..as there is a difference between SM and DM

When i need to change clutch .. i will go singlemass,, and we are talking about difference in accleration ,,,,,,,

I like my S38B38 A LOT

Is this swapped yet?
