im sort of new to forced induction as well as imports as well, but i recently bought a 1994 civic dx it has a meth injected custom turbo kit t3/4 garret turbo running 11psi. otherwise the car is stock. my question is what injector size would be good so the motor doesnt lean out? or what would i need to get the full potential out of this set up? another question about how much power do you think the car is making now? it has a 5spd manual. also sorry if this is the wrong section

 

Too many variables to guess HP/TQ numbers. Drop some coin and strap it on a Dyno for a couple pulls if you're that curious.

As for injectors, what is it running now?

You said "otherwise the car is stock." Does that mean you're pushing 11psi into a stock head/block? What kind of tune is it running?
