Hello, I bought a dohc zc motor that has been rebuilt. It's on a fresh rebuild... around 3000 miles.... the head is ported and polished 3 angle valve job the springs are shimmed, new valve stem seals, new timing belt, new head gasket, new exhaust cam sensor seal, new rings and rod bearings, head was milled 15 tohguh to raise compression.... its about 175psi across the board... its also has a block guard, block and head are spot less. its got a brand new reman. dizzy... This is a complete motor with a Zc tranny.

Since going with si parts would be the best from what i heard..

How can i tell if the intake manifold is an si? same with the dizzy? and the resistor box? As far as the Si tranny and the Zc tranny... Does it make any difference? I'm driving a EF HF. Need to be sure before i put in the engine regretting it wasn't a si part. Thanks.

 

manifold from an si wont fit and neither will the distrubutor. as for the resistor box why does it matter as long as you got one. and for the tranny the zc has shorter gear ration...." im wasting way to much gas on the freeways "
