I've been lurking for a few months here and could use some help/opinions. I've decided my next project will be a 914 with a extra HP, but can't decide on my route. This would just be a weekend car for twisty roads and occasional track days. I'd like it to be functional so I can still take my wife around in it.

I've had a 914 before (back in H.S.) so I know the car and have shadetree mechanic skills that have helped me maintain/DE my previous fun cars (e30M3, e36M3) so I plan on doing all of the work myself. That being said, I don'nt want to make this unneccesarily challenging (some of you guys are way more patient, skilled, and braver than I am). If I go with a Suby motor, I'll do the NA route. I'm considering either an EJ25 or EZ30.

So, the Suby engine is most likely going to have more reliability/last long the higher we get up in HP. It also seems to be the less expensive route. However, it is definitly the slower and more complicated route.

Does anyone with experience having tried both engines have opinions and advice on which is better or what the pro/cons are?

What about opinions on transmissions?

I'm in possesion of a 5-speed MT from a 2003 Forester. It only has 60,000K on it.

Is it a better transmission than the 904? Would it be worth using it just becuase it will bolt up to a Suby motor easier? Does it shift faster and easier???

Thanks for all the help.
