hey guys

I've been doing some research and i want to eventually be running a safe turbo setup that i can put 250-300hp at the wheels with no problem. i want to be able to turn up the boost even more in the future but keep it at around 10 psi for daily driving. I know that i want to build the motor to handle that much. i am under the impression that the iron block of the f22 is strong enough to handle more hp than that so i wouldn't sleeve it. i definately want to go with a 8.1-9.1:1 cr.
I would like to hear your opinions on if it is possible to safely put down that much hp with just rods, pistons, minor head p&p and basically have the rest of the motor stock? i have a spare f22a1 head and plan on buying a spare block to do this on and then swapping that motor into my car to eventually boost. Let me know what i would need to accomplish the horsepower that i want without blowing my motor. all feedback is welcome.

Yes, it possible. F22 blocks are pretty tough. All you really need is pistons and rods and if you wanna do headwork while you're at it (like you stated). When boosting a stock F22 over 10psi, the block is fine, what sucks are the factory pistons. Rings or Ring Landings like to go .

 

do you think that i could run that much power on a stock head but aftermarket rods and pistons? i've looked at some prices for pistons and it looks like they'll be around $500 (arias i think). do you know what would be a good piston/ rod combo and the prices? any details are greatly appreciated!

thanks for the reply and the info

i've also decided to post this in the forced induction section

 

Race Engineering pistons are 400.

the problem is with the Rods... i've only seen crower h beam ($682) or Pauter rods ($702) for f22 motors which will hold out till more than 300whp. but there's no econo rods for the f22 as far as i know.

We're going to try locally to get h23 rods shotpeened and see how they hold up with the race engineering (made by Wiseco) 8.8:1 pistons.

 

are they stronger than the f22 rods or are they both the same?

it's actually an alluminum block with ductile iron sleeves...and 9.1:1 would probably be better for daily driving, that is if you want any kind of power before boost...

i think your setup should be ok...i'm not sure i'd push more than about 15 psi on those sleeves, but with rods, pistons, bearings, etc...you should be alright...also, i'm not sure what head you have currently, but the f22b1 head would definitely flow a lot better than the b2 or a1 heads...

Probe makes rods for us too. I'm probably going to use them.

 

f22a1/a4/a6 heads have larger ports than any of the f22b heads

common knowledge on accordinglydone.com. I searched for a post with pics, couldn't find it, but here's some guys talking about it.

interesting (cheap) piston idea

MY IDEA, I GET CREDIT IF IT WORKS...lol my main concern is expanding the f-series capabilities.

up, i think my piston idea will work, now we only need some cheap rods that will hold up to abuse.

that link was an awesome read. reminds me of the d-series suzuki vitara builds.

 

slightly OT..

what about the tranny? if ya go building up your engine to 250-300 hp, and you leave your stock tranny that was designed for an engine that made 145...see where im going?
or do the honda trannys hold up? both manual and auto.

i see alot of pple wanting to make big power w/hondas and all their worried abotu is the engine and beefing it up. what about the drive train? tranny,cv axles.. ect ect? im talking specifically bout accords here too.. but what about the prelude h22 stuff?

i know some things will last if you baby your car and never shift hard drive it hard and whatnot..but who wants to do that after youve spent all this money to make your car fast?

dont flame me plz...im learning bout imports here..trying not to be an ignorant domestic guy since i have an accord now.

 

14psi.... was daily driven...

 

does anyone know if the h23 rods are any beefier than the stock f22, i know they're the same length, but are they any different?

the tranny (5 speed manual) should be ok internally...obviously the clutch, axles, etc. need to be beefed up to keep from wearing out/breaking...most people on this board with high horsepower accords are using the stock tranny...

now the auto, on the other hand, is another story...it probably won't withstand much boost or any kind of high horsepower whatsoever...

 

i've read on here that some people use buy econo h22 rods and they work in f22's with the right pistons, but i forgot who did it and im too lazy to search

try the prelude forum as ludes came with both f22s and h23s... also theres a few cats in there that have some pretty crazy 'hybrid' builds.

Beef up and get better axles rated for that power, a 3-4 puck clutch and a upgraded flywheel and there is pretty much your beefier drivetrain .

If it's an AT, don't even dream of going boost unless it's 6psi or less .

It's slightly better than the stock rod/stroke of 1.49:1 if you're reaching for Endyn Larry's golden 1.75:1 ratio.

I'm using H22 rods with custom pistons.

right, i forgot the h22 rods were longer. my bad

 

what pistons are you using, What's the compression height, compression ratio etc.
