I've got an m90/euro 3.5 high compression engine in my 79/635.
I've just gotten a 81/745ia donor car for my next motor.I'd like to use the m90 bottom end as it is larger 3.5 vs 3.2, but I'm not sure if comp ratio is too high. the 3.2 is lame off the bottom, vs. my 3.5 will burn out nicely, also the 3.5 has great midrange torque for around town,so I'm thinking just a little turbo boost on topend would make the 3.5 very streetable & fast.anyone have experience with high comp ratio & turbo?
thanks
