hey it sounds like you know a lot more than i do about this f22b motor, i was wondering if it is possible to later down the road put a vtec head on it? the h22 head? excuse if asking an ignorant Q i was just thinkin and maybe you could help me out. i want to see how i can make this motor a bit quicker thanks

 

haha well you have me mistaken for someone with a clue about this engine. I've heard rumors of people putting H22A heads on the H23A1/F22B... For someone like me interested in FI, that prospect is not very appealing to me though. If I remember right people had to fill in oil gallerys and all sorts of funkyness like that.

theres a guy here named TeamElusive.. I'm not sure what his real knowledge level is on the F22B, but hes got one built up w/turbo.. might wanna check in with him. Anyone with a H23A1/F22B can help you since they are about the same.

Use the search next time. Some people really hate it when someone doesn't use the search option. Anyway here is a thread that covered this not too long ago. Also if you use the search you might find more on the subject, I only posted one.

F22B1 head on F22B2 is possible and feasable. H22 head on F22B2 is possible, but NOT feasable.

 

He's reffering to the JDM F22B .. not the USDM F22B1 or B2.

Ooohhhh. I would imagine the the DOHC F22B shares the basic block layout as the H22, but I doubt the work will be worth it. The only feasable frankenstien engines are LSVTEC and CRVTEC. Even doing the H23/H22 frank would be a biatch and cost a shitload.

 

What??? Are you talking about the F22B DOHC non-VTEC, then putting a H22 VTEC head on it?

 

Oops, quess so. Sorry, I misunderstood.

 

Dont worry, so did I.

 

Gennady, the SiVTEC has been done before rather easily.

 

From my research the H23A1/F22B share more in common with the F22A1-4-6 (maybe the B1/B2??? but i think they have different rod lengths.. dont know much about the F22B1/B2) Than the H22A*.

Obviously that doesnt include oil/water passageways, but far as rod/stroke/BEB etc the F22A1-6/H23A1 are pretty close. H23A1 has a .039 bigger bore than the F22A1-4-6.

One interesting thing is the F22B/H23A1/F22A1-4-6/H22A share the same deck height (i'd wager a guess the B1/B2 as well)

I'm actually working on a H and F series engine Excel spread sheet with every possible spec ... so if anyone has thoughts/corrections etc lemme know. I would use journal widths for all the F and H series engines if you have them

My F series motor guide is there to help you out.

 

I'm working on a spreadsheet for 90-97 (emphasis on the 5th gen) to break down all the specs (and differences). Let me know when you get that shiznat together.

 

unfortunatly its on my work pc (man i have a boring job), or i'd post the spreadsheet now... will paste a link to it tomorrow
