Dude, you cant make a sohc a dohc. your going to waste your money.. i looked in to all that. i also have a f23a1 motor. i just ended up buying a 95 jdm h22a..

 

don't think that's ever been done on f/h series engines because it is cheaper to swap in a h22 for your f22. sohc to dohc conversion is a waste of time and money

 

a guy over at honda-tech(iirc) got the full gude package for his f22 last year and it worked out to be about a 10hp increase at the wheels. a far cry from the claimed 50hp.

 

core charge is basically a deposit. you pay them $500 and when you get your new head and have it put on, you send them the old one and they refund your $500 core charge.

 

I completely 100% dont believe that, or anything until i see dynos....people always go around guessing about horse power, but they NEVER know unless its dynoed, period. So if that 'person you know' has a dyno, then ill shut my mouth. Cuz I know for certain that it will give my car a lot more power then that.


I emailed mmrusa for dynos of other cars, and my car...ill update this thread if they holla back with the dyno's.

 

whatever dude.. do the research and do a search here.. the gains aren't anywhere near as impressive as they claim

 

dude, at http://www.totaljdm.com you can get a complete H22 paclkage with tranny for like $2200...heck of alot more worth it than a frankenstein head swap....(it has been done though, if I find the link to the forum, I'll post it)

 

Nothing against you or anything...all im saying is that people come in with hear-say, and hear-say is almost ALWAYS bullshit, im just tired of bullshit, i want dyno numbers instead of hear-say. Seeing as the site claims something, then backs it up with an actual dyno, im going to believe them over you because they have FACTS not hear-say.

Thats true, a h22 is about 2200 bux, but i couldnt boost a h22 without either going very low on boost, or blow up the engine. Plus, this mod is almost a grand cheaper. I could use the difference to have the head package installed, and i'd be close to a h22's hp with it...

bubb out, woo woo

 

i know a non-vtec to vtec swap only ains 15hp.

 

Okay? whos talkin about vtec? anyways my car is already vtec....
