I used the NISMO rear with a 4.36 gear. It does fine at Sebring and Moroso. It might be a little short on gear for Daytona or maybe even the front stretch at Roebling if you get out of nine(?) fast. Remember, this is NOT a vtec engine, it is a long stroke small bore engine. More torque, less rpm. have you reprogrammed the ecu?

Gauges...I have tach, O2, H2O temp, oil press., Oil temp. oil light 25psi and oil temp are in remote filter adapter. oil gauge is in stock location on the block. H2O sensor is in a pipe adapter in the radiator hose. All the gauges are Autometer except the O2 gauge. It is from summit.....

Send me your emails and I will copy everyone with my answers (FWIW) to any questions...
