Wanna know why so many people think CRVTEC and LSVTEC setups are not reliable? That is why... So many people use the stock fuel system and ecu... and when their car eventually starts burning oil they think oh its just because these engines are not reliable. More displacement on a much better head than what was originally on the block means more air which means you need more fuel. Your stock ecu is not up to it and the lean condition would be even worse if you had higher compression pistons. Get a wideband and some way of getting more fuel in before you overheat a piston and it scuffs the cylinder wall.P0gKai said:... I think is running way lean
The other reason people think CRVTEC and LSVTEC engines are unreliable is because owners think they can rev beyond 8k on the stock rod bolts.
