hey guys have a g22 swap.the f22b2 block is stock but i plan on ordering pistons and rods.question is how much power/boost can stock sleeves handle.anyone recommend putting new sleeves?looking hp wise anywhere between 4 to 500whp.thanxs guys.

 

nobody has a clue?i was thinking sleeves are good for maybe 250-300 whp.anybody agree or disagree?

 

I agree with the 300whp. Anything over that and you are going to want to stabilize the cylinders. Looking for 4-500whp you are definitely going to want to close up the open deck or pin the cylinders.

 

It's do-able.

 

The original 4-500whp on stock F22b2 sleeves & cylinders. or the later mentioned 250-300whp....

 

What is there are forged internals on stock sleeves? And is there a block guard for the F22?

 

yea ordering bisimoto pistons and rods 9.1 comp.i believe ive come across a block gaurd for f22 but 50% of people say it creates to much heat.the other 50% say its ok.

 

I want to get that combo too. Hmm I never found a block guard.

 

The H22 and F22 are the same block guard. If these are installed properly there are no issues. The H22a1 is a closed deck with less flow rating as most block guards have. The key is how far down the block guard is installed in the block.

The block guard should be pressed 1/4" - 5/8" into down past the deck surface. It should obviously be aluminum and it should be tig welded into place. Tacks will do! Then the cylinders and main journals should be honed/aline honed.

I have a good quality H23/H22/F22 block guard if anyone is looking.

 

It is possible on stock sleeves with good internals IMO with proper tuning and setup to support it, but it honestly has never been put to the test. Upper 400whp-500whp range I would though put at the limit of what I think is a good gamble personally. I made well over 300whp on a bone stock motor besides fuel, management, and a turbo setup. Others have as well. The internals are the weak point... the sleeve is an iron sleeve in the f22bx so it is very strong. Currently though I use a sleeved block and again never tested the limit of the stock sleeve first hand... although I was very tempted but my plans have taken me further than I think the stock sleeves would handle.

I would say that would be no problem on stock sleeves, again given of course proper tuning and setup. I made well over 300whp on all stock internals and sleeves for a good bit of time before a mistake I made hurt the motor a year or so down the road. Others have as well gone beyond 300whp on stock motors... the sleeves are not the issue.

I do not agree but understand the logic for why people brace cyl's. Open deck Honda motors with unpinned and unbraced sleeves have made huge power. No less done incorrectly, pinning or adding block gaurds could actually cause you more problems. For 4-500whp I do not think you need any additional bracing, you would be better served with spending that money on tuning, fuel, and management.

 

you guys are all great,lots of opinions.i am know some people make in the 300whp range,myself my car dynoed 280.9 whp.would of done better if i had a perfect(nice clean bend).the tuner says fix down pipe and go to 3 inch exhaust,tune on e85 and i will make 400whp.that sounds good but how long will that last.thats if it dont blow up on the dyno.tuner is good i just dont think it will last.thanx again for all u guys info and opinions.

 

280whp to 400whp is a heck of a jump for fixing downpipe, exhaust, and retuning on e85. I would imagine it would take a good bit more boost to get you there as well.

Also if your talking 400whp on stock internals now, I would say your pushing it definately. If your talking 400whp on good internals with stock sleeve... go for it if you have a good tuner and such, I would at least.

 

How much boost can stock internals take?
