i have a 94 ex with a motor that is done for(190k miles). any ways, i am opting for a jdm d15b and then i will be boosting that cuz i already have the turbo kit. what all should i be buying for this as a complete swap besides the motor? just the po8 ecu instead of the p28? any wiring harness's?

Direct bolt in. Use all your old ex stuff. You dont need the p08/ p28 will run the d15b just fine.

Yeah just use your P28 cause that P08 runs off a one wire o2 sensor so save yourself a headache and stick with which yah got.

Whats odd about po8's is I have used them in cars that came w/ 4 wire o2's and ran the 4 wire 02 and have never had any problems

I would think you would get a CEL for there not being a heater enabled.

ok, thats what i thought, just use my p28. but some of my friends told me to get the po8 because it will run better and something about the p28 is 4 pin or... i dunno. soo, what would be the difference between the po8 and p28 on this d15? and what about heater enabled on which ecu? annd, if i get the po8 what will i have to do with wires to the o2 sensor?

don't you have to use the driver side mount off the z6, or is that only in ef's?? and yes, use your p28 with the 4 wire o2 sensor that came in your car and all of your z6 accessories (distributor, starter, tranny, etc.) that should save you some money, all you'll need is the d15b longblock

ok, so i guess i wotn get the po8 ecu but i was thinkin, i was gonna have my ecu chipped with uberdata anywasy so it might as well be the po8 and then i can sell my p28.
