i swapped civic 2000lx to d16a engine..mechanic who did the swap said it was a d16y8 engine..he didnt put the vtek wiring .so i hired a guy then he put a d16y8 ecu then everything messed up with check engine lights..ended changing o2 sensor..knock sensor.then changed intake manifold.we both thought it was a d16y8 .but it was a d16a..car works fine but im looking for a boost which is not there..it still runs like a no vtec engine..i wanna ask the honda experts here what shoul i do! thanks much!

 

Are you expecting it to be noticeably more powerful? The D16A isnt much different if at all then a Y8 from what I remember, the ECU should work fine, but its no screamer of an engine, I think they were rated at 130PS which is about 127hp IIRC

 

do u think i should tune the engine? like a dyno tune..and one more thing how about the transmission, the tranny before was from an engine without vtec.does it matter, cuz its shifting weird too like slipping and jerking

 

I wouldn't waste my time with a tune, I doubt its worth it. just make sure its running efficiently as intended. The trans shouldn't really matter. Slipping and jerking may be a whole other issue.

 

what do u think about the chips you can put on the obd port? like the Honda Civic - Performance Tuner Chip & Power Tuning Programmer, does it even work? thanks

 

Dont waste any time on that fuckery

 

What are the ECU codes you are getting? It sounds like the transmission is automatic, so did this supposed mechanic use an automatic ECU?

Trying to make an automatic Civic faster is silly. You want a good running stock setup though, which means using the right parts.

 

yes he used an automatic ecu

 

any suggestion or mods that i should do? thank you.much bro..

 

Same issue here. However here is my Set UP
BEFORE SWAP
1997 Honda Civic EX 1.6 D16Y8 Automatic Transmission P2P ECU
P2K Intake Manifold


AFTER SWAP
1997 Honda Civic EX 1.6 JDM D16A Automatic Transmission P2P ECU
P2K Intake Manifold


Everything was Stock Prior To Swap.

Engine is lacking power, No Check Engine Lights On, New Knock Sensor, New O2 Sensors Upper and Lower, Aftermarker Headers,
Called Local Honda Specialist and he told me that i need either a P05 or P06 ECU, Which he can convert to Run VTECH. Resolving my problem. I would have to install a OBD2 to OBD1 Adapter to P05 or P06 ECU.
