update: well the d16z6 can fit in the si in the 5th gen so i think the only problems i am running into now are if i will need to get new brackets for mounting it, if it will bolt to the tranny, and im not gunna be able to look for an ECU until i know what the whole engine code is.
And another question would be, if i were to want vtec, could i swap my y8 head over? i just installed it last winter on my y7 and i really dont want to get rid of it.
Hopefully i can buily up my y7 while the new engine is in there. Not planning any major mods but i want a reliable engine with the y8 head on it again.
