Ideas for swaps other than a V8.

Exhaust is on the front since they are all transverse mounted so in an FR it would be on the driver's side

That's what I thought. This is the only down fall I see with the SR20 as well.

The 4G's exhaust will end up on the passenger side, which would make it easier for steering rack clearence.

We built this 3sgte, http://www.cj-motorsports.com/galmr2.htm , This was a cool build. Funny thing is, before this motor was purchased by the MR2 owner, it was offered to me. My FD had a blown motor at the time

85rx-7gsl-se its cool you know about the 2.3l turbo motor.
P71 the heads are not that hard to find.me and my buddy are rebuilding a 1984 rs turbo capri. paid 220 tho my dads work, loaded head cam's ect.
finding the old after market ford big bore head is hard.the new ford racing heads are really made by esslinger. theres http://www.esslingeracing.com they make all most every thing for the motor and will mod there head to work for what you want.

we have 3 motors for the car right now. the stock 2.3 that came in the car. the 302 with a 4 speed(giving away for free) that the guy we got the car from was swapping in and gave up. also we got another 2.3 from a b2300 ill talk about this in a bit.

alot of people say a full 2.3 weighs the same as a 302. stock for stock i dont believe this is true. me and my friend where able to pic the motor and trans up, we couldnt do the same for the 302.

the stock motor we fully built up custom piston's , t3/t4 turbo fmic, gutted and knifed edge in take ect ect.
full cost of fixing the blown motor machine work and head was around 1.5k$ thats include clutch setup.

the second 2.3 that we got out of a b2300 where converting it to dohc.
theres a a bunch of mustangs that have done this. you need a volvo 16v head

.the hardiest part of this is welding a block of metal on the back side of the head and slotting a few oil holes in the head. then get the head fly cut so it sits flat other then that its basically a bolt on job. o yeah you need to run one external oil line.

on a na motor it adds 100 hp. so if you convert a na 2.3 to a dohc its all most making the same power of a stock turbo 2.3. also a na motor with this head swap make more power then the v8 from some years

.

am not making this up and will post links if you want to see how its done, i did leave out little minor things but its not that hard.
