ls vtec

[bozos_civicsi]

I was thinking of putting an ls vtec in my 99 si but i have some questions!! i want to know if there is any difference between the 90-93 integra ls blocks and the 94-00 integra ls blocks?? would the 99 civic si head have any problems fitting on any of these blocks?? what hydro trannys would fit the 90-93 integra blocks?? I am thinking of using a 90-93 integra block because i can find those anywhere and they are the cheapest!!! would a b16a vtec head work with it?? would the internals in the 90-93 integra be able to hold up the high compression or would i have to do some changes in the internals??? All i have for my 99 si is the engine wiring harness.. no ecu, motor mounts, axels nothing!! Please help out!!!!

you can add either short block both will fit just fine. it is recommended to change the pistons and rods. that is pretty much what you will need in the internals. good luck with it, you'll definetely will be running much harder than just the b16.
