Want to know if I can keep y7 tranny and just change the block d15b vtec or am I better off to switch the whole thing. d16 is burning oil like crazy and found a d15 with low milage for dirt cheap? on a restricted budget so not intrested in bigger engines.

its fine. It's a straight up and down, so don't worry about it. Make sure you get the right ecu with the engine though.

wait a sec, you said d15b vtec in ur header but d15 in ur post? Which is it? Big differences...
d15b OBD1 has the word VTEC on the head, looks just like a 1992-1995 Ex/Si engine, and will not work in your car without some wiring issues aka going from OBD2 to OBD1.
d15b OBD2 has the word HONDA on it, looks just like a 1996-2000 Ex/Si engine, and that one is a direct drop in with your car, just need the right ecu.

If the motor is the OBD1, get a wire conversion harness and you'll have to do a few steps too, not sure exactaly. Best stay away, not worth it imo.
If its the OBD2, ffs get it. Lean burn mode? Holy fuck ya!

Hey man, I am doing a swap to D15B from a d16y7 in a 2000 civic ... I found out that the ECU code is P2J (is that right?) but I can only get ahold off of an auto ecu which will disable proper vtec engagement because it will think that it is always in PARK ... are there solutions?
Thanks

RoughKnight

hey man, first off

1) Get your own thread

2) Google it

3)...

4) Profit!!!

Since you're new, i'll give you a break. If you can only find the Auto, I suggest calling HondaMotorsOnline and other various sites and seeing if you can find the manual. Being it OBD2, you are REALLY limited for chipping/tuning for vtec and proper fuel maps. So the only solutions I can see are...

Get the manual ecu

Convert to OBD1, get the P08 ecu which is plug'n'play (but no lean burn mode) or chip and tune a p28 (what i'm gonna do).

Also, call phearbale.net and xenocron about possible vtec addition to your ecu. I dunno if you can play with a OBD2 ecu like that, but its worth a shot to see what they can do for you.
