somebody please do a search! the EJ22t is the 22b engine. i have been running same engine and heads for about 20k on 20psi. you just need the right fuel setup (555cc for me). you can only run about 10-12 psi with stock injectors. and xypher is running 30psi with bigger injectors than me (850cc). if its not a rebuilt motor to the average tuner these blocks are indistructible. my block has about 40k total on it, bought mine new from the dealer for the same price.
look for the thread where xypher tells all in this forum. it is very informative.
