hey guys im new to the forums, i have a 96 prelude with a F22 in it. im looking for more power and have decided on the G22 build. i havent been able to find a DIY on doing the swap, if anyone has a link to one, or to a basic instructions that would be awesome thanks.



iv found swap info for a F22B2 w/ H22 head but i have a F22A1 which is non vtech

 

You mean H22 right?

 

F22 + H22 = G22. Welcome to Honda Math.

 

Let me Google that for you

 

haha how it does the search for u >>>> LEt me Google that for u nice job A+

 

Hey there everybody,
Im currently in the middle of my own G22 build and ive made some progress So heres some of what I do Know.

Im using an H22 head and an F22a1 Block. And on top of that Ive bored the block over 1mm to fit a set of K20 pistons, But thats besides the point. Heres what I Know as far as parts.

For an H22/F22a1 setup

-H22 HeadGasket
-H22 Water Pump Pulley (F22 water pump w/ the H pulley pressed on.. Can Simply be done with a Pulley puller and a press But remember aluminum pretty sensitive)
-H22 Crank Pulley
-F22/H23 Manual Timing Belt Tensioner

Ive learned what oil ports to block for this combination, Ill try to upload some pictures soon but ill try to exlplain it clearly.
-The H22 vtec head has 2 more oil return ports that the F22a1 block.
-The 2 H22 oil return ports are on the timing belt side of the Head.
-If you are looking at your F22a1 block"s (Timing belt side) of the deck you will notice 2 lone headbolt holes, where the 2 H22 oil return ports would run straight onto the deck if the Head's 2 Extra oil ports were not blocked.

Another thing I know is to add a VTEC head to any non VTEC F22A/B block you have to remove the oil control orifice. (In the middle, Intake side of the deck)

Ill try to add pix sooon

thx pc

 

when you do a visual check on the head and the block.. you will be able to tell which two ports of the HEAD that will need to be honda bond (or whatever method you want)

 

So In my case, there is 2 more oil ports in the H22 vtec head than the F22a1 block provides

 

oh oh oh also, can anybody explain whats up w/ the rear balance shaft in the f22?? You put a bolt thru it and hold it still? I confused

 

On an H23 head you use a little Hondabond, but on an H22 head the holes must be plugged with bolts or allen caps or whatever you can get to seal in there

 

Right on, I've also read and seen a picture on cb7 where a dude welded it, then smoothed it all out like it was resurfaced. I intend on getting some allen caps in there. Ill make somthin happin soon, ill provide some visuals

 

im in the process of doing a f22a t3/t4 turbo build n im not sure on what head to use? does the h23 bolt up the same as the h22? just plugs up diff(hondabond/allen screw)?

 

Headbolts will line right up, deppending on your head and block combonation and the headgasket your using. You'll have no problem determining any oil ports that might not line up. Hondabond and allen caps are comon practice for blocking these oil ports

Another thing I know is to add a VTEC head to any non VTEC F22A/B block you have to remove the oil control orifice.

 

Stay away from the auto tensioners they are known to fail. Keep the manual one off the f22. Many people including myself convert from auto to mechanical tensioners on the h22.

 

On my G23 build Im currently set up with h23 cam gears, h series manual tensioner, f22 water pump h23 crank pulley and my h23 timing belt is tooo short! Can anybody point out the flaw in my set up!?.

 

wut arp head stud do i use for h22a head on a f22b1 vtec block my head is blocked an ready for the block i even got a h23 head gasket im just not sure wut studs i can use cuz the f22b1 studs say u cant use a h22 only h23 so wut studs do i use pls someone let me know asap

 

The studs for which head you are using. H22a= h22a studs, h23=h23 studs.

 

i have a h22a1 head going on a f22b1 block but i dont think the head studs are long enough plus im going turbo so i need arps but im not sure wut ones i need i have a h23 head gasket i read on the forums that u need a h23 head gasket to make the g swap work right

 

When using all H components both the head studs and head gasket need to match the head that you are using, aka H22.

For sure any build using an H22 head will use the H22 head studs

If you look through some of the old G frankenstein build threads, if there is a need to use a different head gasket, aka F23 gasket, it should be mentioned there.

 

thanks for the info i have another question will h22 ARP head stud thread into the f22b1 block or will i have to tap the block

 

i to am doing a g22 build with same bottom f22a1 and an h22 head.. ive already done the f22a1 bottm with h23 head but friend gave me an awesome deal oh an h22 head ($80) plus my h23 head and along with the g22 im going to go boost also but that wont come till another month or so.... so when your done let me know how your build goes as will i.
this monday i should be puttin my head on so ill take some pix..

 

and yes your ARP's will work with f22 same as h22

 

Hey bro I have a 94 Prelude and my motor blew it's a h23a1 the head is still good I also have a 94 Accord motor with a bad head LOL I'm trying to do the G22 non VTEC can you please steer me in the right direction what I need to do thank you in advance

 

totally not worth the trouble

 

i may be 10 years late but i have a g22 turbo with the same block and head, you need to plug the 2 extra holes in the bottom of the head and get custom axles and mounts to make it fit into an eg civic like i did. As you have a prelude it will be 10 times easier for you lucky duck
