H-22 swap in a prelude
yo, im posting for a buddy at work.
hes thinking about swapping out the H-23 (non-vetec) in his prelude for an H-22 vetec jdm motor. im trying to convince him to slap a turbo on it.
he wants JE forged pistons, which i told him is a good start, but the rest im not sure about. i told him itd probably be a good idea to get a good forged rod, i recommed either an eagle or manley H-beam. i think an x-beam would probably be a little overkill.
also, what about the crank? ive heard that the honda cranks are pretty tough, i said he could probably get away with just having it gone over at the machine shop while the shortblock is being put together. any comments on the durablitly of the stock H-22 crank? is it forged?
now, hes saying because its a japanese spec motor, its gonna be a right hand side drive and hes gonna need the proper harness, ECU and tranny. he needs a shop to wire in the ECU and harness, i recommended millineum, but ive also heard positive things about next level performance. any opinions on either shop? let us know whats up so we can set him in the right direction.

Re: H-22 swap in a prelude
if hes going to boost something...tell him to rebuild the h23, and boost that....
if hes going to put those pistons in it, then hes going to need to get it sleeved....
call up tuners edge tho, theyve done many a one...
988-1911....

haha
a jdm h22 does not mean the car will be ride side drive....and he can keep the stock tranny from a h23 and it is vtec not vetec.....
If he is gonna be rebuilding it, stay h22 not h23....

Re: H-22 swap in a prelude
ok, so if he were to do the h-22 headswap onto the h-23, i was looking at JE's website, and it said that the h-23 combustion chamber cc was 50. but the h-22s combustion chamber is 53.8 cc.
so what yall are saying basically is that the h-22 is gonna drop the compression enough for him to run a decent amount of boost? i was looking at the chart, and it seems that if he got the pistons for his h-23 with the stock head (10:1 compression), if he did the headswap, then it would knock the cr down to around 8.8 or so?
what are the benefits exactly of the h-22 head over the h-23 head? lower compression/ more cylinder volume seem to be the obvious 2...are the valves bigger?
my advice to him was, to get the higher compression pistons (for use with the stock h-23 head) that way when he does the h-22 headswap, itll bring the cr back down to a safe level for a decent amount of boost.

The material on the H22's sleeves are extremely strong...forged pistons are made of material that is quite soft compared to the sleeves. The two just don't match.
Here is a pic of what happens when you try to use forged pistons in a FRM sleeve.
