max rpm on boosted h22....
hi, ive got a jdm h22a and my set up for the time being is : t3 60 trim turbo, 3in dp, inline fuel pump, 12:1 fmu. for the time being i'm just gona run low boost like 5.6 or something like that jsut cause my fuel set up is shitty... l8ter i'm gona go with uberdata.. l8ter this winter.... i am just curious.. whats the most i should tack my engine with this fuel setup? i mean without boost i can tach it to somewhere near 8 grand... but... i just wnat to know what you guys think is safe...
(and i know i should be going stand alone from the start.. but i just cant ok!! haha
) ) Thanks in advance

I have a 92 SI with a JDM H22a. I put a custom turbo kit that I pieced together with a Garrett .63 57To4E and Ido not take it past 7600. First, what makes the most sense is to see where you power dies off. But then again, you will have to get it dynoed. But if you were making power past 8000 rpms, I still would not suggest to run an h22 that high since there is more crank vibration with more displacement. That's why they have the balance belt. The Hseries are just not a high revving motor like the B16 and the B18. I would say at the most, take it to around 7800. Play it a little safe.

yeah ive also heard never to hit 8k on a stock head. just like ITR said, i personally would save money for a dyno and see when your peak power is, cuz that gives you more of a reason to base your shift point/rev point to. no matter what i wouldnt go past 7.5k unless youve got money saved for a new engine

Depends on what you mean by "8 grand". The tach is notoriously wrong when it comes to RPM. If you have a VAFC, you can see it for yourself. Common consensus is that the tach is off by about 600 RPM at redline. So when the dash tach is showing 8k RPM, you are really at about 7400 RPM. Fuel cut on both the US and the JDM is at 7600.
Boost isn't a factor with turning revs. The only two factors are bottom end geometry and valvetrain. If you haven't modified either one of them, then your redline should stay exactly where it's at right now. Come to think of it, it doesn't sound like you have any device capable of modifying your redline, so why are you asking??

thanks for all the responses... what i was realy asking is if i should baby it (like not tach the **** out of it).. while using the cheap setup before i can go standalone... but from what i have seen... you guys say i should be ok with the stock revlimits? thanks again!
yeah definitely ditch the fmu and inline fuel pump. I had the inline fuel pump and vortech fmu on my gs-r when I first got my turbo kit, now I have a Walbro intank high pressure fuel pump. Dont risk leaning it out, get rid of that shitty fuel pump.

oh yeah, personally i think you should 'baby' it, id go no higher than like 6.5k, but i thought you wanted to see the limit it has and go to that. just like the guy said about the tach being off a bit, youve gotta keep that into consideration.
i guess it all boils down to how crazy you are and how much money you have. if you dont have money to replace it, then dont be going ANYTHING aove redline. like i said, id shift a little bit before redline. my reasoning for that is when you shift, your rpms will still creep for a split second, which may be cutting it too close.

Well thats actually f20b which is "supposed" to rev higher........
It took it to about 8k

really 8000 stock valvetrain. I have a built motor with a built valvetrain (crower) stock cams. I take mine to 8800 with no problems , but thats at the track and usually i have to readjust the valves after each event, so my advice is even with the valvetrain built, be safe and don't take it past 8500.

Well This is supposed to be a Better head than the Stock P13 stuff...
Its PCT I believe, Type S cams, Aggresive port work. The motor revs wellover 8k stock I believe.
The valvetrain is pretty beefy.

thanks, i'm flattered. I got some outside pics of the car, unfortunately the car is temp. down due to some fuel issues. hopefully it will be running by the end of next week.
i have a external pic on my aol profile niesech22civic@aol.com
