actually i never have rebuilt 22rs my experience is with vw motors, for sure well developed aftermarket cams are better performing, but there is the trade off of fuel milage. and longevity and the block was not bored .50 over, its actually .020 over the pistons have a marking of .50 which is next size overbore i think. i just found out the head is a china casting, the valve seats on the exhaust side was so pitted in only 20 k miles. I'm torn if i should do a mild port job or just slam it on my current block in the truck get it running and build up the other one with a Toyota head slowly.
does anyone here have a Chinese head that has lasted a good long time?
also the turd that rebuilt the motor last tightened #3 exhaust to .005 thou and it wrecked the cam and the rocker arm!!
lucky my bud has an extra 22re cam EM . ill go to pick-a-part on sat to find a used rocker.
bumbed out that i have a
aftermarket head.
