Team English Racing FAQ:
Q. Timing belt?
A. Same as stock. Just reset the idler on the tensioner. requires minor trimming of the pump and cover to fit. Not big deal for the engines these are made for!
Q. How much does it drop oil pressure?
A. 1100rpm idle is 20psi, the pump doesn't exceed 90psi even with rolled bearings (deleted shaft). Cars that have a balance shaft delete but retain the shaft will be in the 80psi range which fits the old 10psi per 1000rpm rule even better.
Q. Why?
A. Reduced load on the oil pump will mean reduced failures of both pumps and engines.
