hey guys am thinking about building a nasty 650+whp street car but i want to do it on high compression 11:1 to be exact. the motor i want to use is a h22a4 or h22a1 since it is cheap and easy to find and will be built anyway. my car that i had before it was stolen put down 435 at 22psi and i was not impressed, my tq was only 350 or so. i had aebs sleeves back then but now i am thinking on going with the darton mid kit. I plan on reving this motor high as well let's just say around 9.5 so rod choice will be important as well. the bore will be 89mm so it's suppose to be 2.3l instead of 2.2. what i wat as well is for this motor to see 20-25psi by no later than 4k rpms and it has to hold the power all the way to 9-9.5.
if anyone can give me info on how to get my build up and running please help me out on the specs and what not. and what turbo, rods ect.... will be needed. i know this will not be a over night build but i plan on the first motor start up by mid to late summer 2006.

Why do you want to have an 11:1 compression ratio?

s2kdre

u can do it but pump gas wont be good enough for daily driving,

The Weather Man

Is there any reason you want high compression?

High compression won't help a boosted motor....it'll just make tuning and driveability a bitch.

Some people say they want high cmopression because they want better low end - to solve this, get a smaller turbo or a ball bearing turbo. I say stick with the 10:1 c/r or go down to 9:1............

ALso, at 22psi - 435whp sucks *****. What kind of turbo were you using?

mash80

I was using a ptesc63 bigshaft turbo 76trim on the hot side 63a/r and 63mm wheel on the cold side with .70 a/r t3 housing.

I am not worried about the gas because will be buying a 55gal drum of turbo blue.

I want the 11:1 compression because i want to make good torque numbers and almost instant throttle resopnse. also i i think it will help me to see 20-22psi by no later than 4k. I dont care if i get 450 at 20psi i just need 450 or more by 4k rpms and no later. My last turbo setup was on 9:1 comp and i saw 22psi at 5.5rpms and i was shifting at 8k. so i think with the high comp i will get my hp goal of 450+whp on low boost (20-22psi). but the problem is i will also rev this motor to 9.5 and i need the power to hold all the way trough. the torque needs to hold strong also. my max hp goal is 700whp and i will be very happy if i can get that by 32-35psi. and a mak torque output of 590-640.


thanks all for taking the time to read my post

Way to buy into all the honda-tech hype. High compression doesn't spool up a turbo quicker. You're also never going to have a motor that holds power to 9500 RPM's, makes 700 WHP and 640 ft-lbs of torque. And to make 640 ft-lbs of torque to the wheels you're pushing the limits of gasoline period, and I definitely wouldn't want to be running massive compression so you can get some supposed off boost gains. Might want to think about something like C16 because 110 octane turbo blue isn't going to cut it for 35 psi into an 11:1 motor. Hell, might want to rethink this entire project because as it sits you sound like you're getting in way over your head.

beerbongskickass

Go with 9:1...

Get yourself a dual ball bearing turbo if you want it to spool faster. That would be a much better idea. It's not like you will be able to use all that toque anyways, it's a fricking honda!!! Hondas are FWD cars with dinky tires, it will do you no good on the street, unless you like having to wait until your going 100mph to get traction lol.

93hatched_projekt

If you want to keep some compression in the motor , but be able to still throw a good amount of boost. Look into the endyn 9.5.1 http://www.theoldone.com/compo....html or a little higher pistons and maybe a gt35r will get you to your gool no problem. Fast spool to 9k and will make 650whp all day on a built h22 with race gas.

CoreyR

your asking for a turbo with spool characteristics of a GT28RS and the power capability of a GT40 or a T3/T67. not gonna happen buddy.

ccivic

No way in hell you're going to reach 700whp on 11:1 compression unless you have money to be replacing anything and everything every run down the track. Highest I would go is 9.5:1 or 10:1.. I don't even think you'll find a tuner that would attempt to tune that!

warmmilk

there is no turbo that will give u 20 psi by 4k and a top end of 650 to 700 hp, and the high compression won't give u more than 50-100 rpm in spool, if that

high compression isn't all that bad if u want to make around 400-450, but if u want 600+ u gotta bring the compression down unless u want to be rebuilding ur motor every 2 months

mash80

well i dont want 9:1 or 9.5:1 compression the lowest i will get is 10:1 or 10.5:1. yeah i know it not going to make the turbo spool faster but what am looking at is the power i will have by a certin rpm and i think with the high compression pistons i can get to my low boost hp goal of 450 faster than if i had 9:1 compression pistons. why wont my motor hold power to 9.5? with the right turbo i should be able to see power past 9.5 even tough 9.5 is my limit. yes i know the torque will fall off but what can i do to help it hold a lil longer trought out the powerband? i know the gt35 is a nice turbo but is it the right turbo for my setup and my goals lowend and top end?

The Weather Man

The motor isn't built for high rpm ranges. I say the most you should go is 9.5k if not lower.

beerbongskickass

Why do you want that much power so soon in the rpm range? Forget about the motor or turbo because you will NEVER get a chance to use that power on the street or track, especially since you will be reving so high. You will launch higher than 4k and when you shift your rpms will never drop that low. If you did have that much power down low your tires would just break loose.

this sounds like a dyno quen setup, I dont think this guy is at all interestd in going fast.

mash80

i understand what you are saying but since my car got stolen this idea been lurking around in my head for quite some time now and am just starting to follw trough. so lets just turn this into a big project and deal with the problems as they come. because to every porblem there is a solution.am in no rush to get this car on the road i just want the motor to be in the car by end of summer next year i dont mind having to pay for a custom turbo just as long as it will do what i want.

b16hybridsol

i'll throw in my 2 cents on this because everyone else is buying into other hypes on the board but criticizing you for it.

first off i'd like to see some proof that higher compression doesn't help spool charateristics of a turbo, aside from evans gsr test (stock "high compression" vs a built lower compression bottom end) way to many things that aren't equivalient to even call it a comparison.

with that out of the way your power goals are retarded, you need to drive a 500whp honda then rethink your goals, I don't know what was up with your setup before but if you weren't impressed with over 400whp you need to get out of fwd hondas. you can't really use much more than that on the street. hell, i light up the top of 3rd with like 360ish whp.

you need to decide where you want you realistic power band to be. I don't see a problem with 9k reving as long as the head is built to take it as well.

research a little bit more before jumping into something like this because for what you want, you are going to spend enough money that you could havea much faster car in a different platform

not trying to be a ******* but do you know what torque is?

mash80

Torque is a measured number of force delivered from an engine at a certain point and is RPM independent.......lol

Boostage

Mash, I think he asked you that because he knows that kind of TQ will never do anything but spin on the streets

mash80

you guys bashing me just because i want to to something that a little out of the ordanary, calling me names and all that **** is not called for. asking me if i know what torque don't ever insult me like that again.

since you want to quiz me ama quiz you...................

a engine that makes 300 pound-feet of torque at 4,000 RPM produces [(300 x 4,000) / 5,252] 228 horsepower at 4,000 RPM. But where does the number 5,252 come from?

Boostage

5252 is where tq and hp cross. but seriously why do you want to spend all that money for a peace of mind that you car makes good power. it snot lie it would be fast on the streets, it would just spin.

You obviously don't understand. Go back and read my post. You won't have traction.

gents97civ

Turbo blue is leaded correct? I dont think that would be a good choice.
