Need some input on engine choice

And Jenkins you have taught me the fe3 is a better motor then I thought. But I still like the sr20 more lol. Viva la slant top! Lol

I am currently running the stock 2600i rear with my 350. I get 20 highway.
Soon I will be transplanting an LSD rear from an S10 with 3:23 gears.
I hope to get better than 25 mph at that point, but a 2:73 gear would be awesome.

Tell me about it I hated to sell it the motor was low mileage all I needed was the wiring harness, the problem though these newer engines are so f'en complicated to wire I would've basically need an entire 350z front clip and transplanted everything over into the B, plus you need access to a consult II. Too much hassle not worth spending all that money for a 280hp motor

If you're gentle, the std box and rear end will handle 300hp too
Though I hear you guys have a different diff over yonder?
Some have non-lsd? Or am i on the wrong path?
