Hey guys, I've been playing with turbos on my Sunfire, but as most of you know every car adapts to boost differerntly. Now I'm on my way to get a civic LX 95, I'm planning on turbocharging that car with arounf 4-5 psi. What do I need as in fuel mods like FMU or injectors?

How much boost can this engine take and how much gain as in hp and tq am I'm going to be looking at 4 psi?

Thanks man, I don't know much about a civic, so this is the start of my research.

 

4-5psi? Dang bro whats the point then? Hit that b7 up and boost around 10psi to get something worthwhile out of it.

 

well, I don't know about any civics, so I'm planning on keeping the boost low. But I would still like to know how many pounds can these LX from around 95s take.... Don't wanna blow it and no other upgrades except for exhaust and fuel on the turbo.

 

FMU is ok for 4/5 psi.
But don't forget it's the worst "fuel management".
You can boost at approx 10 psi with larger injectors and "real" engine management, like uberdata

 

ive got 390 cc injectors and everything you need to install them minus new seals. they would work PERFECT for the d15b7. thats what i planned on doing but then i got a great deal on some d16 blocks.
