Boosted fully build h23 block

[lildeez07]

wuz up you guys i just have a few questions. i have a fully build bottom end H23 with forged rods and piston heads and sleeves. well ofcourse i boosting it so i wanted kno how much psi i could run safely. i mainly worried about the valves how much can they take

Whats your target HP that u trying to have

[lildeez07]

im lookin for around 400hp to the wheels. my boy hit close to 300hp on his stock F22a1 at 16psi. so im pretty sure i can hit 400hp on a forged h23

[drummersteve7]

so pistons, and whatnot, how about posting up a list of what you are actually using.

any headwork?
regardless lets us know!

can't really predict what your hp numbers will be without proper information.
plus I love the H23 engine so. I can't wait!

500 is pretty easy. if you have a built block i highly suggest at a minimum springs and retainers. and a good turbo choice.

I think the save way to run the H23 is about 16 psi as well...No more than 18 psi. Depending on the parts and your turbo you should get about very good results but the H23 is more torque then horsepower. So if you should get around the same about of power as the F22a1 but your torque number will be higher. For example when I dynoed mine, I had like 296 hp but like 270 torque. You will see....you will love it!! Might want to look in changing the Intake Manifold....I ran with a golden Eagle....Top end is very nice with this upgrade...Later

if he is built with sleeves rods and pistons his bottom end is good for 30+psi

Its more so about how much power vs boost. b/c u can run 20 psi on one turbo and be fine. But 20 psi on a bigger one, my mess something up, b/c of the more power u making. If u stay below 400 ft lb of torque, u should be find.Torque is what breaks stuff.

Both of you guys are right....I don't know what the extend of his build is nor do I know what turbo he is running. I am just basing it off of a normal size turbo. Like a 60 trim and my experience. I know one thing when you straight getting in the 20 psi on the 60 trim you have to start running racing fuel.

ok well i have brian crower rods and piston heads. king main and rod bearings, and darton sleeves the crank has been rebalanced and micopolished there is no head work as of now but im saving up to get some new valve springs and retainers. and some brian crower cams.

specifications?
I mean just saying you have pistons is like saying I have a car.
its not enough info.
but ohhh well, it doesn't sound like you want help at all.
I mean do you have high/low compression pistons?(numbers are good)
piston heads, (oxymoron) which stlye, dished?

so moving on to bigger and better things!
good luck!









BOOOM!

[lildeez07]

whao hold on there buddy calm down if its specs you want then you got it.
the pistons are 87.5mm dished 9:1 and i say piston heads cuz when most ppl say piston they think the rod and piston are all one part so my bad if i affended you by saying piston head

[d112crzy]

What kind of people do you talk to that thing pistons means pistons and rods?

I'd stop hanging around them because they are lowering your IQ score.

[drummersteve7]

Im not offended, just wanna know exactly what your talking about.
You seem to have potential for a great 1st build.
Just wanna make sure all your questions are answered correctly.
and without all information your answers will not be perfect.

so despite anyone giving you shit, its a learning process.
Not just for you but everyone collectively.

lemme know if you need any help.

[lildeez07]

i do need to know what are some good rings i could use that would be able to support high psi like 30 max
