Hello, I'm new to the forums, but have been visiting the site for months now. I'm about to turbo charge my 97 Civic Ex, SOHC Vtec. I already have an IHI RHB5 turbo, HF manifold with the turbo flange adapter plate, Starion FMIC, Greddy Type-S BOV, Greddy Turbo Timer and Boost gauge, I will be running a OBD1 ECU from a 95 civic ex, chipped so redline goes to 8500rpm's and Vtec starts at 5000rpm's. I'm planning on boosting the car around 6-7 psi. For Fuel management what should I need?? Do I need better Injectors? Planning on getting an APEX SAFC or VAFC, to help get more fuel in there, better control. I do not want to blow my engine so I want to do it right the first time. Also any of you guys can think of anything else I need to complete the kit, or anything that would help. Anyy help will be greatly appreciated.
thanks
David

 

A FMU will work good for low boost like what you are doing, but I would go with the AFC hack.

id leave you vtec crossover at the stock setting.

On Adams Z6 the run we made with vtec at 4200rpms was the worst run he had... He had his vtec set at what? 2200? I belive on single cams its a bit differnt for the vtec cross over point.

OK, My car feels like the vtec kicks in @ 5500, and this chip will change it to 5100, so it might not be too bad. I will try it, it is an extra ECU, if it doesn't work too, i'll change it back.
thanks for the info
David
