First i would like to say Hi to every one.

Ok now I have a couple questions concerning my ressent upgrade. I have a 91' Civic hb Si an i put it a Zc sohc in it an was wondering if i should upgrade my ecu, and if this would give me any more power for the money. an about how much would it cost to do this. Next I was planning on putting new injectors in it but am not entirely sure what size i should get or brand ( if that matters ) an was wondering what you guys would suggest i do.

i would like to increase my power, an lower my ET times with out having to spend alot on mods. any sugestions would be helpfull. thanks in advance.

ps. sorry if i missed a topic on this already.

 

I'm not sure about the ECU. But for increase power you should get the usual bolt ons such as Header,air intake and exhaust.

 

I have an intake exhaust. an gonna get the headers in a in a couple of days just gota wait for my pay check. Was wonderin also what other bolt ons can i put on.

 

head work, P&P, larger throttle body, tuning (fuel and timing) cam, cam gear.....don't both with the larger injectors your stock ecu will compensate just fine.

 

what size cam an cam gear should i get that wont be to over kill for a daily driver an were would i go about finding those.

 

crower comes to mind. I'm not a N/A guy so I'm not going to be much help in that area. It depends on your future goals and plans, figure that out and contact them with your plans.They can guide in the right direction

 

thanks a bunch

 

You still running the Si PM6? You could gain a little bit if you were to run a turboedit chipped PM6 and then you could adj for later mods.

 

the ecu is what ever was stock on a 91 civic si hb i believe it to be the pm6 ill have alook at it see.
