Is there much difference in the cam profile between a 20R & an 89 22RE as far as lift & duration?
The situation is this: a friend has an 89 IFS with a high mileage 22RE. Cam chain, guides & tensioner were replaced with cheap stuff 2 yrs ago. Chain is noisy again plus it takes a few minutes for the noise to lessen. I will be replacing the oil pump, timing set & lash adj screws with new Japanese OEM parts. And possibly the timing cover depending on the corrosion. He has little money left for a new cam & given the mileage of the engine, would rather replace the cam at engine overhaul.
Will a good condition 20R cam work well in the 22RE engine?
Provided its needed that is.
