92' Corolla GT-S didn't come with TVI-S. It came with a small port non TVI-S head red top engine. The 88'-89' GT-S came with a red top TVI-S big port head engine. Either heads will fit but with the small port head you'll need the big port to small port intake manifold adaptor.gotdrift said:I was going to pull the head off a red top motor with tvis coming from a 92 corolla GTS and was wondering if it would fit onto my current motor, a blue top also with tvis. My car is a 86 corolla GTS.
any help would be appreciated.
Like hachi_slow said, that it will fit with no problems. The only difference between the two engines is the 88'-89' red top engine and the 85'-87' blue top is the bottom half. The red top is the 7 rib block compared to the blue top 3 rib block.hachi_slow said:^ maybe he was referring to AE92?
you mean Bluetop TVIS big port?Ninja7 said:The 88'-89' GT-S came with a red top TVI-S big port head engine.
actually, the 7 rib block came in the 86,87 too.... basically the 86,87,88,89 engine are the same... even tho it was marketed higher hp on the 88~89.Ninja7 said:88'-89' red top is the same as the blue top but the bottom half was different between the two engines. The blue top has the 3 rib block while the 88'-89' has the 7 rib block. Until 90'-91' the red top again changed with small port non-TVI-S and the 7 rib block came with oil squirters under the pistons and 10:3-1 compression pistons.
