vtec, not vtech.

i was able to put a f22b1 into my 92 accord (f22a6). not sure how much extra work you'll need because car is OBD-I, but new motor is OBD-II.

straight swap

how different is the OBD-II motor from the OBD-I motor. extra sensors, etc?

not to steal thread,
but when i bought my jdm f22b (vtec), i couldnt figure out which OBD it was, but it runs fine, no CEL, so i kind of assumed that it didnt matter which OBD it was.

the 94 is obviously OBD-1 and the 97 is OBD-2, you will need to manually rewire it or buy a conversion harness to switch the engine from OBD2 to OBD1. Most likely the easiest way is going to pick up an OBD-2 engine harness and use it for the engine, then use that conversion harness right at the ECU. Meaning the ECU needs to be OBD1.

BOTH ARE VTEC

DUDE!!! you dont know $H&T......the new motor has extra sensor....and if he uses his old wiring and his old ecu and his old tranny or watever.....he will have his car running like before......the new motro has a crank position sensor that he can get rid of....and he can use his old dizzy....and about the EGR i dont remember....but worst case senario....use his old IM and period

tamadrummer1120

ok no reason to be talking like that. I am just telling the guy his new engine is OBD-2, because I do not want him to think that the engines are both the same wiring wise. There are some very minor differences, yes. I am just offering one route. Sure he can also go the route you offer.

i ment it in a good way....that why i put the #$%%^^^& signs.........im sorry for the comment....the buddy her need to post up pics and that way we can help better...i did couple of f22 cars....and some were f23 from 03 accords which they are obd2b so.....all i used out of the new motor was just block and head.......i learn something out of honda-tech and it is "make it simple on yourself".....there are many ways to with this.....but in this case the old ecu works perfect and the less sensor your ecu has....the better.....so all you need to do DARK BOLIN is buy yourself one of those gasket kits out of ebay(buy the OEM head gasket, dont use the one that comes with the kit) and change most of the gaskets on the new motor.....crank and camshaft gasket(make sure you get the viton ones.....those are like marron color ones) and for the old intake mani.....is the best manifold you can use......make sure you tide everything to the right torque and you be back on the road in no time....good luck

no they aren't





i hear that with the f22b1 motor, the f23 intake mani swap is the best choice available, unless you want to go the h23 route, but that involves some fabricating (cutting, grinding, etc).

tamadrummer1120

Oh ok hahaha.

All good.

accord3955

the guy wants to get his car running.....once thats done, than some other time he can do preformance tips

Dark_Bolin

thanks swaps was susesfull but now i have code 22 and 41 help again!!accord3955 thanks to you and everybody!

tamadrummer1120

Code 22 is VTEC system malfunction, check your connections to the VTEC solenoid.

Code 41 is HO2 Sensor. Test the oxygen sensor, possibly needs a replacement. These codes were found in the FAQ section, so if you have anymore arise, check there.

What difference is it going to make when we all get the point in VTEC. lol Everything from a 94 to 97 motor are the same; everything is mostly straight forward except that the new motor might have some extra connectors such as the crank angle sensor, etc.

JdmAtlcd5

whatever he just said

tamadrummer1120

I believe the OP was just saying he had CEL codes, and according to his codes, i just copied from the FAQ.

What's the problem with saying that?
