will the intake mani from the auto y8 work on the 5 speed y5 if that is what i end up doing? is there anything else that i could swap to maybe get a little more out of it cause im still not sure about keeping the y8.......im still up in the air with it
D16y5 vs D16y8?

why would you swap if you dont drive fast anymore? and only care about saving money?If I could go back and have a choice of a motor for a DD, I'd get a y5 for the gas mileage. I don't drive fast anymore so all I care about is saving money. But B-Series (particularly B18B) is more ideal for me since it has good power:torque ratio and still gets good MPG.
Intake will bolt up, but y5 vtec is different then y8's vtec. You'll have to run an hx ecu and hx wiring harness with a 5-wire primary o2 sensor to have it work right though, trust me I had to with this setup. Or you'll have to get a chipped ecu and get it tuned to engage vtec around 2800 rpm's. Go to Honda-Tech and do some searching to find out for sure at what rpm the vtec-e (y5 head) engages.
Use the ex wiring harness and o2 sensor, but you will need to get a tuned ecu (p28 I think) and tell the tuner that you have an hx head and vtec needs to kick in earlier. Remember another guy posted that the hx head only uses one valve until vtec kicks in, so if you use an ex ecu, you'll only be using 1 valve until 4800 rpms and it will run like crap after 2800.
The hx ecu needs a 5-wire o2 sensor and egr valve, so you'll get cel lights for those and the motor will go into limp mode to protect itself (thats what I've read antway).
You needed a chipped ecu to get around all these little differences between the ex and hx.
anyone else know what else i will need to do cause this is what i am gion to end up runnging i think......the hx motor cause its already together and stuff with the 5 speed tranny......im goin to swap the intake mani from my y8 and the headers with a 4 wire o2 sensor in it.....i will be using the wiring from the ex because i don't have any with the hx.......
The e stands for economy....slowest of the slow!
well this is where im at now........take out the y8 rebuild it a lil bit and then put the hx tranny on and get a ex ecu and call it a day.......or just put the hx motor tranny and ecu in and everything will be ok.....but idk any more ideas or opioins?
