N/A G22 vtec

[Lao Tuner]

so waddup fellow tuners i was hoping to get some advice from you guys i have a g22 and want to kick it up a notch . right now i still have the f22a1 pistons but it pulls hard so it got me thinking what should i do.

My wish list:
11:1 forged piston 85mm
440cc injectors
walbaro hp Fuel pump
some aftermarket camshaft/gears?
and basic I/H/E and get a tune.

i am not looking for monster but reliability. i pretty sure that all i need and was wondering if anybody can tell me what i am missing?

You'll need some forged rods unless you plan on using the stock ones. You'll have to rebush the small end if you plan on using the stockers.

You'll also need bearings and rings.

WHat's your power goal? You can hit over 200whp with stock cams, as long as the rest of the engine is healthy and you have the right parts to do it.

What head are you using?

I would bore to 87mm and buy the proper pistons then do some head work while you're waiting. That way you are definitely able to make some power when you decide to throw in a new set of cams. If you're running an H22 head I would definitely get a Euro-R Manifold.

THe OP would need to sleeve the block if he'd bore out to 87mm on an F block.

Also, Euro R isn't needed to break 200whp. He'll break 200whp and have some nice torque to go along with that 95mm crank. If the motor was built right anyways.

He doesn't "need" to sleeve it, most would do that if they for some reason felt the sleeves wouldn't hold up. I've seen an F22 bored to 87mm and the spacing and wall thickness looked fine. I definitely wouldn't go over 2mm's without sleeving but the motor ran as far as I remember following it.

I mentioned the Euro-R not so much to say it's needed to break 200, but to give him more power throughout the powerband as we've seen it give gains throughout (13-15 in both whp and tq).

well i think the stock bore limit is 86 on f22a but i am not bothering with that "leaving it stock". but i am using a h22a4 head and i am using stock f22a rods but new bearing and rings are deff.

will forged rods be that necessary i am not even gonna break 230whp and probably not even 200 whp can u even tell te diff with camshaft/gears?

i am too worried about the "number" as long as i have a good power band

[d112crzy]

No, rods aren't necessary for such a small build. I actually have stock f22 rods in my build(206whp/172tq).

But for the forged pistons, you'll need to rebush the small end of your stock rods to make it work.

And no, cams nor cam gears aren't really needed. You will definitely notice a difference with cams, but it mostly depends on which cams you go with. Some aren't much better than stock.

Hold on I thought you couldn't bore a stock block due to the FRM sleeves.

[d112crzy]

He has an f22 block. It has iron sleeves.

H series has FRM sleeves. I'm not so sure about boring, but I know they can definitely be honed. I have not seen a 100% confirmation that you cannot bore them, so I don't believe any of the nonsense I read from unexpereinced people.

Bore it over 1mm and get standard bore rsx-s pistons..

Compression is your friend when trying to make power all-motor.

[d112crzy]

Not true sir. 13:1 has yielded over 300whp on a 2.3l h22 block.

exhaust and intake systems play a HUGE roll in how much power you'll make when it comes to all motor.

I always see people getting some high compression pistons, flat faced valves...etc...and then use a cheap ass header which results in completely shitty power.

[FDAccord]

I would say they go hand in hand when it comes to all-motor.

[d112crzy]

Everthing goes hand in hand when trying to make power. You can't just slap on random parts and expect shit to work well together. You have to make a well flowing system.

But just becuase you have high compression don't mean you'll make good power. It defiinitely helps though.

I used to read about the G22 a while back but it's been a few months. As far as I can remember though I thought people were having problems with the reliability of this motor? Or maybe i'm just ignorant/misinformed......

If you find out if the F22A can be bored let me know. That would save me time and money with sleeving it.
