I just purchased a car from a guy who did a 99 Civic Si Swap in the car. He did the instrument cluster, motor, and transmission and everything seems to be working well.

However, I noticed a few problems:

1) I noticed that when you are in 5th gear and cruising down the road, the cars RPMS are right at 3500 @ 60 MPH.

2) I have also noticed that according to the RPM gauge in the car, the VTEC doesn't come in until 6200 RPM.

I used to own a 99 Civic SI and know for a fact that VTEC comes on at around 5200 and cruising at 60 MPH in 5th gear the car is definately not turning 3500 RPMS.

Can someone tell me what may be the problem and where I need to look to try and fix it ?

Thanks,

Robert
