my friend has a h23, and wants to put a h22 vtec head on it. He wouldnt have to change the pistons or anything correct?
Also, would he have to get an h22 vtec ecu?

 

Hey man,

I honestly think you should talk to Dave(GreaseMonkey) and Chris Stearns about that.

From what I've gather'd talking to them about it, it's like the LS/Vtec of the H world. The more you go into it, the better it'll run.

And also, from what I've gather'd, the motors don't last very long, due to the H23 being unbalanced, and it being turned really high rpms wise.

He'd be better off getting a H22 swap,(my two cents). But def. talk to the two people I listed.

(and I've yet to meet you )

 

lol, i was the thinking the h22 head and the h23 bottom end would be like ls/vtec.


p.s. i know lol..


p.s.s. Im gettin my motor soon!

 

Same thing here, but Ive been told that the whole thing including labor will cost about $1100 while a full H22 will cost about $2100 after labor, or you can Turbo for about $1200 and get more ponies then doing any of those 2

 

ste had a h22a prelude

greasemonkey helped put the motor in.

i would suggest talking to them before doing any work.

 

actually, it would be a good idea to ask for advice from me or grease monkey. i however, would not be the smart choice. grease monkey did the engine job for me.

 

That's incorrect, H23 cranks are balanced..

The most likely cause in H23 VtAk! setups is the fact that H23's have much tighter tolerances on the main and rod bearings compared to H22's.. naturally, because of each engines characteristics

It's no suprise when I hear of STOCK H23 vtec setups spinnin rod/mains lol..

 

here's a link on someone who did one in his prelude http://www.92lude.com/forum/index.php?showtopic=4017

 

The H23 bottom and H22 bottom is the same pritty much,use a h22 timing belt and h22 water pump and head gasket.
