[WD40]

Thanks for the info California98Civic.
So now I need to look for a 88-91 CRX HF D15B6 5 speed transmission ...
I read that the 88 has different spline, so it would need a matching clutch.
Other years match the VX clutch.
The difference in gearing would make 5th gear at 1700 RPM doing close to 56 vs the current 1900 RPM at close to 56.
That should pay for itself pretty fast as I currently get approx. 80-95 MPG at 56.
I see a few on CL in the USA, but none in Canada yet, but I will be searching.
