I recently purchased a 1970 914 that was converted to a 3.8 Buick in 1982 but only completed to 90% finished. I am almost finished but the engine has to come out due to timing cover gasket leaking. I am considering changing it all out to a Subaru 6cyl and 5speed Subaru transmission. What donor car should I seek to complete this project? Can I use the engine cradle from the 3.8 Buick? Will it be modifiable? Thanks.

3.8 GM engine is a fine engine, I would go EFI and supercharged if you want to make something odd and interesting. Stock it is 240HP, a PCM and a pulley swap and you are getting closer to 270 if you think you need it.

240 is a pretty decent number in a 914

Engine is darn near bullet proof, except the latter ones that switched to a plastic water inlet manifold. But most of them have been fixed by now.

Do I need to change over the intake on these fwd 3800 SC engines? What I have read is you need the RWD Camaro upper and lower intake. Thanks. This would be much faster to build and more economical.
