I got a 92 accord exr stock 2.2L non vtec, and need a new cylinder head. Just want to know if the heads from 90-93 are all the same? and would i need new head bolts or could i reuse the old ones? any help is appreciated. thanks

Not exactly the same. There are some differences between the 90-93 cylinder heads. With a 92 EX-R you would be looking for an A4 or A6 head. As for the head bolts it will be OK to reuse them as long as your not planning to boost the engine.

 

not the same, but interchangeable without modification correct?

 

Without engine modification they all bolt up. Yes.

Remember that they use a different ECU/tune, cam and a 4-2-1 tubular exhaust manifold setup. A4-A6 are the higher performing heads. Not sure how a stock cam & exhaust A1 head performs with a PT6 ECU.

 

completely interchangeable without any noticeable difference esp if just using head.

 

i do know that the PT6 ecu runs the butterflies for the A6 at about 4200rpm. (pt6 for sale, PM me)

i also hear that it is recommended you change the head bolts, but my dad has done a few head work and used the old head bolts, still running 220k strong, nissan just as durable as honda.

 

thanks for all the responses. so any head would bolt up, but if i don't get an A4 or A6 it wouldn't run properly because the ecu is tuned differently? i assume A4 and A6 cylinder heads are only found on EX-R?

 

what is this ex-r? is that a canadian version? The A4 n A6 is an EX option.

 

No, The Canadian EX-R is actually a type R equipped with a red top Euro-R H22A7.

lol Yes the EX-R is the Canadian equivalent to the US EX.

 

My eyes almost popped out of my head when I read that! A COOL CAR IN NORTH AMERICA! LOL

 

lol i wish i had a type R. I have an A6 Head
