Hi

I was given the following : A blue top twincam 16v head with T-VIS intake<big> with injectors + loom .i was also given the distrubutor ... still waiting twincam Computer box from a friend


planing on getting a second car

now the Question is i have a 4AF<corrolla>
i did some asking around and read and i am told that the block is the same that the head will fit
with out any problems...

but my concern is the pistons is it the same or does that need to be replaced or what more needs to be replaced




like i say this will be a project thing as i am planning on buying another car
