thanks for the help, i had seen this before but wasent sure about it.thanks a lot man.

nicolas1320

yo one more question do the egr valve from the h22 fits this engine and is this an important sensor to have?

crx_91si

Important, i guess it is if you have to pass emissions testing....will it fit, it should. I know i swapped my EGR from my F22 to my H23A just because the connector faced a different direction and i didn't feel like lengthening the harness. Fit just fine so i imagine the H22 should work.

crx_91si

and a P73...you gotta ditch that **** real fast man, unless you got some sort of fuel controller to compensate.

Not to nitpick or anything but..... Euro R / UKDM Type R Accords don't have a H23A.... they run a H22A7. You might need an OBD2B Pinout as well seeing as the 2001 JDM Accords run OBD2B ECU's.

H23A VTEC = JDM CH9 Accord Sir Wagon

and if you need the OBD2b pinouts, here ya go




** for JDM, ECU"S, SWAP PIN A15 to A16

well sorry for replying so late guys,well when i bought the engine they said it came from a euro type r accord the block says h23a and is vtec,but if thats the case i know i have a jdm engine for sure. and is it better to put basemaps on a p28 or im better of getting a p13?

GlassJAw

I would run a P28 as you could always retune as you do upgrades..... what kind of chip are you planning on running in the P28 if you don't mind me asking?
I guess the guy who sold it to you wasn't completely wrong, the Euro R Sedan & CH9 Wagon Accords do look alike, so he may have been saying that to give you the idea of what vehicle it came out of.

nicolas1320

well about the chip i dont know yet im finding that out this week,but i here alot about chrome chip or the hondata 300 but i dont whant to go that deep i just want the engine to be safe.

nicolas1320

what chip would u recomend?

nicolas1320

most likely im thinking chrome......

GlassJAw

I'd suggest a chrome if you're a little on the tight side of money things, but a Hondata if you can stretch your budget that far. I'm contemplating reverting my Euro R back to OBD1 and tuning via Chrome as well, let us know how you get on with your tuning.

nicolas1320

ok cool i think ill jump on that offer,i was thinking on putting h22a basemaps on it,what u think?

nicolas1320

question did u change the intake manifold or u left the one it came with?

GlassJAw

I wouldn't gain anything from changing my intake manifold - my car is actually a JDM Euro R Accord (CL1 is the model code)
An H22A base map cleaned up would be "OK"..... but a tuned map would be better. (as I said all down to budget)



Also you may need to source a USDM H22A4 Power steering bracket as the CH9 Accords have EPS (Electronic Power Steering) and dont run a power steering pump.

There's two way you can go about it, one is to attach the bracket I mentioned and muscle your standard Power Steer pump onto the engine, or run the bracket and power steer pump off an USDM H22A4 and modify the pipes to fit.

crx 91si is the man..... have a look at this thread
https://honda-tech.com/forums/honda-accord-1990-2002-2/6th-gen-f23a1-f20b-swap-thread-2724062/
(F20B is a destroked H22A from the same family of Accords your H23A came from)
It should help you with the wiring of your ECU.....

nicolas1320

ok update on the ecu thing. today i took it to the shop,they put the prelude basemaps on the p28, the car runs a lot better but no vtec,im going tomorrow back to the shop,but the car even thoe it runs a little better it runs kind of funny,if i let go the gas it shuts of.im thinking on changing the hole manifold. can any body let me know about this thanks.
