Looking to fit a F V8 into a BMW E30. I kneed to know if anyone has done an engine swap like this and what direction the engine turns. i was thinking a Getrag 265 geabox with a dogleg and 1:2 top gear. The car has a 4.3 rear end so should make it silly fast its currently a 2.0 in line 6, auto.
I really like the idea of a small V8 180 degree crank and compact light weight engine. There is a 348 motor floating around here in aus so may come together? Any thoughts and ideas would be great. in the end it may not go ahead, but the car is mint, but just does not have any go, and after running around in the TR I need more.
Now that I've had a little more time looking at the 348 powertrain I bought for my 308, I think I see some potential sticky areas.
While the Dino engine is smaller than the M/S62, it's still a DOHC V8 and the left cylinder head will still interfere with the brake booster and linkage.
The 348 engine has a dry sump system. This means that the sump is very shallow. While it is possible to fit the engine very low in the body, you won't be able to in the E30 due to the location of the front suspension crossmember.
Also because it is dry sumped, it will need a high capacity external oil cooler and external oil tank. This will take up a lot of space in the very small E30 engine bay.
The 348 did not have power steering, so there is no power steering pump. A V8 E30 without power steering will not be easy to steer. The Mondial T's have power steering... you *may* be able to source the bracket, accessory drive and PS pump from one of those, but you're probably better off just making it from scratch. If your car doesn't have A/C (or if you don't want it) you can probably mount the PS pump in place of the A/C compressor.
The 348 exhaust headers simply will not fit in the E30 engine bay. You'll have to fabricate headers from scratch. You will need to build long tube headers in order to preserve the 180 sound you want.
Because you'll have to build long tube headers anyway, use the BMW V8 and build "crossover" headers with 180 degree collectors. Two cylinders from each bank feed each collector in this arrangement. It gives the same exhaust sound as conventional headers with a 180 degree crankshaft, but without the 180 degree crankshaft. Youtube "180 degree headers" for some examples of sound clips. This layout was used on the original Ford GT40's and is common on GT40 replicas.
