I decided to go with a d15b vtec in lou of my stock d15b7 (non-vtec). Its my first swap so i have questions. I will have the p08 ecu. Car is a 92 civic dx sedan. 1st i need to know if it will bolt up to stock mounts and tranny. 2nd if ANYONE has done this swap please inform me what parts i may need. Im getting it from HMO and im hoping its all plug and play aside from VTEC wiring. Im tight on cash atm so i cant afford much more than the motor and ecu, so please let me know what to expect.

Thanks

 

Just to confirm you are getting the OBD1 D15B SOHC VTEC correct?

Yes it will bolt up to stock mounts and tranny.

The only parts you'll need will be if you want to do any maintenance (tune up, timing belt, clutch, etc).

Plug and play except for the VTEC. You'll need to wire up the VTEC solenoid and pressure switch (some JDM engines don't come with this so you'll have to see if it has the pressure switch when you get it).

The D15B will come with a one wire 02 but I'm pretty sure you can reuse your 4 wire as the white wire will still be the same signal wire.

 

yea im getting obd1 d15b sohc vtec and thats good to know. and what type wiring should i get for vtec and oil pressure switch? Thanks

 

You'll need to either buy or make a harness that goes from the solenoid and pressure switch to the ecu

 

wher would i buy one or where could i get the proper wires to make my own? And also would full exhaust transfer over or would i need a new header? 1.5 to 1.5 im guessing it will fit...
