Alright first post here. I got a 92 coupe, 5 speed. i got about 70k miles on it so i dont wanna do a full swap. My friends tell me to do an h22ag1? head swap. so im thinking about doin that. But what are the differences of the blocks between an f22 and an h22 same gen? Could i bolt up an h22 header? and im also going to build the living crap out of the f22. thanks

 

Welcome, and heres a link to someone who did the h22a head swap onto his f22b2 block, it has more information than you could possibly need to decide whether or not you want to do this swap. if you do decide to do it, keep us posted!

dont bother

 

"Could i bolt up an h22 header? and im also going to build the living crap out of the f22."

to be honest, you need to do a ton of research before you attempt either project will save you a lot of heartaches and will be easier on the bank later on...

 

The search button is your friend.

 

to sum up his 20 some pages of text, its cool on paper but damn near impossible...and don't even try it if this is your only car

I give him major props for doing what everyone else said was impossible and overcoming all the obstacles, but its just not practical. I like knowing that if my belt splits I can get a new one, or if my hose splits I got one in the trunk. Not true with a hybrid monster, a lot of it you gotta make yourself.

and if your friend told you to jump off of a bridge would you do that too?...on the same note I say to kick your friend in the *****

 

and while we're on the issue and the picture an the link reminded me of this...

The F22 block DOES NOT have cylinder sleeves correct. So if you break a piston rod or something and crack the cylinder you have to get a new block, right? That's what it looks like to me but I've never had the head off on mine (keeping my fingers crossed). Anyone?

 

everyone has always referred to them as cast iron sleeves.... wish my block was here.... havn't looked at it really....

 

They are iron and the short blocks are so cheap you can blow one and buy another with just a couple hundred.

 

just buy an H22A it less trouble

If you wanted the flow qualities of the H22 head and the strength of the f22 bottom end then this is exactly what you want, and it would be less expensive then building an H block for boost.

 

well my friends done it before. twice. the f22 block with the h22 head puts out more torque than an h22. he said the only thing not to do is rev it past 7200. his **** still runs

 

Get an H22A4 (most have the 55mm main journals), sleeve it and bore to 89mm, Use the F22 crank and rods. It will give you 2.36 Liters (almost the same as the K24) and tons of torque. The sleeves allow you to run forged pistons and a larger bore for a turbo. We've built several of these for customers.

that sounds interesting. I have never heard of that setup. More details please.

 

yea I like that, none of the head mating (sp?) problems, teeth counting, and tensioning problems that he had. Same goes for all the custom made crap. What does the labor for boring it out, and parts run? Don't suppose you'd have any dyno info. for that do ya, not that I'm ever gonna have the time or cash?

I know on the Nissan Maxima engines guys have been swapping out the crank and rods from the Pathfinder, adding half a litre, and getting way better torque. By the way does Honda made a variable intake (yes intake, not VTEC) like the newer Maxima's or Mitsu's. Cuz there again on some applications you can swap intakes and grab some major horsepower. Not quite sure how these intakes work, I know its got butterfly valves on it that changes the length of the manifold, but the dynos speak for themselves [called a MEVI I think]!!!

 

There isn't a variable runner intake for the honda that I know of. The basic conversion is simply using F22 crank and rods in the H22 block and having 89 mm pistons made. The big thing is to find an H22 that has the larger 55mm bearing journals. There isn't a way to tell that I know of by the serial #, the only way is to disassemble and check it (we have both in stock). The H22A1/2 (I know the closed deck doesn't). We have align bored the H23 to accept the larger journals, but adds to the cost. If you have the block and crank, the cost to build isn't any more than a sleeve,piston,rod purchase to build a std H22. We close the deck on all of our blocks, so the H22A4 is as good as the H22A1/2 blocks. The custom JE pistons cost only a little more (depending on options) than shelf stock.We also can Deckplate the H22A4 blocks for longer rods. Since we only sell thru our dealers, I don't have the dyno sheets. You can contact tim @ TSR 1-410-760-5995, he has an H23 with the F23 crank we did. Frank @ 1-613-802-0385 has done some of the Deckplate motors.

The H22 IM has variable length runners.
