i just dot a 89 crx dx with the d15b2 and i was wondering if i could just put a vtec head and run the vtec wiring and oil lines. or if i have to do any thing else.so basically just wondering if a y8 or z6 head will bolt on and all i have to do is run the lines and wires i have experience working on hondas but i just need to know if it will need alterations to the block or head bolts locations.i read that you need a new water and oil pump but i dont know if i believe that any help will be appreciated

 

You don't need to replace the oil pump, but you can, you should do the water pump seeing how you'll have all that off to replace the timing belt. Your also going to need to swap from DPFI to MPFI, and then hookup VTEC.

 

why would i need to swap to mpfi for the fuel mapping?because im going to use an electronic injector controller to deal with that the (sds eic). i have the manifold and all the ---- from an ex to do a mpfi swap but ive been puttting it off because im not to good with the wiring harness. for the vtec im going to use an msd rpm window switch to activate my vtec and set it at 4krpm. and use the injector controller to kick in at 3750rpm right befor the vtec and once i turbo it i can tune it better

 

Wow, $350 for just the EIC, you could buy a conversion harness and chipped OBD-1 ECu for that price. Then you don't need the window switch and can adjust fuel and timeing directly from the ECU.

 

i know were to get the conversion harness i just wouldnt know were to get the chipped ecu and some times it just people scamming people so thats why i wanted to do it that way.but your suggestion sounds cool to. but i would not know how to tune a the mapping becuase i have no knowledge tuning ecus this would be my first time changeing the ecu out and converting the mpfi

OBD-1 VTEC ECU:

OBD-0 to OBD-1 conversion harness:

If your not interested in tuneing right away you can just use a stock P28 and have it chipped later if you need to.

 

ok thanks for helping me out with that all i need to know is will the head bolt up

 

It'll bolt right on, just pull the restrictor out of the block or VTEC may not engage.

 

You'll also need a timing belt for either the z6 or y8, depending on the head you use.
