My build is almost complete, lets take some guesstimates about dyno numbers before i get it dynoed.
My setup
B16 vtec head with retainers and dual springs. B20b block with JE 12:1 pistons. Si tranny. toda A cams, Walbro 255lph fuel pump, FPR and S100 to tune everything. My car is civic coupe with obd2-1 conversion and P28. that is the jist of it.
Also lately I have heard this sound coming form my vents in the car. It is only there when i accelerate and it gets louder dependeing on my rpms? It is a hissing sound. Any ideas?
thanks
