can I get 300 hp from a h22 n/a?
if yes then how?
if no then how much can I get and how?

H22's already have high compression ratio. Adding another 100 hp from the stock power it produces will take more than high compression ratio pistons and a good flowing head.ya'll are retarded, some high compression pistons and some good headwork could get you 300. You just need to find a good engine builder in your area. Being in cali, you should have no problem finding one.
HAY SMART GUY!ya'll are retarded, some high compression pistons and some good headwork could get you 300. You just need to find a good engine builder in your area. Being in cali, you should have no problem finding one.
300whp NA is in a different ball park than 300whp turbo.so would you say that it would be more efficient to put a turbo on it rather than biuld up a motor? or should i say if i had a motor all biult up and was putting out the 300 and a different motor with a turbo on it and thats basically it would the turbo'd motor be more effective?
dude the h22a is far inferior to a k20a2 and they start to see there limits at around 270whp on pump gas n/a. you will not get 300whp just by adding what you're talking about. take your head out of your butt. that is a complete race block and build to do what you're talking about. it will cost 10's of thousands of dollars.ya'll are retarded, some high compression pistons and some good headwork could get you 300.

why would you want a 300hp n/a 4cyl for the street? that thing would be a piece of shit on the road and get spanked by better tuned cars with far less hp simply because you're powerband would be retarded and the motor would be very unreliable. and if you have to ask you can't afford it even know where to start to do it. get a t3/t4 57 trim turbo, run 8 psi on a good tune and make more than 300hp at 5% of the cost of what you were trying to do. peak numbers mean nothing remember that and don't forget it. you want a linear power for your car on the street. the most important thing is research or you will lose alot of time and money. good luckcan I get 300 hp from a h22 n/a?

although it would be interesting and nice to see.... never the less it is not cost efficient... ITB's anyone + direct port injectors ?why would you want a 300hp n/a 4cyl for the street? that thing would be a piece of shit on the road and get spanked by better tuned cars with far less hp simply because you're powerband would be retarded and the motor would be very unreliable. and if you have to ask you can't afford it even know where to start to do it. get a t3/t4 57 trim turbo, run 8 psi on a good tune and make more than 300hp at 5% of the cost of what you were trying to do. peak numbers mean nothing remember that and don't forget it. you want a linear power for your car on the street. the most important thing is research or you will lose alot of time and money. good luck
for the amount of money to do it. he could've made a built boosted k24/k20head combo with boost destroyed that h22 frankensteinalthough it would be interesting and nice to see.... never the less it is not cost efficient... ITB's anyone + direct port injectors ?
Why does midgrade cost less than regular?Gas prices will own you before you ever get that high of power out of the car.
Gas avg yesterday in california 4.77/gal and today the avg is 4.80
Last week the avg was 4.16
Last year the avg was 3.33
Highest premium around my area? 4.33/gal and highest out of the region is about 5.09 for premium out in wrightwood (whereever that is)
Highest midgrade around my area? 4.00/gal and highest out of the region is about 4.99 for midgrade out in wrightwood (whereever that is)
Highest regular around my area? 4.11/gal and highest out of the region is about 4.89 for regular out in wrightwood (whereever that is)

& Depends on how you want to drive your car.
If you accelerate without opening the throttle too much then you should be about the same fuel economy as you would without a turbo.
When at the track you would be on the throttle as much as possible, so your fuel economy goes down a considerable amount.
Accelerate hard when you need or want to, but as a daily driver there arent too many times when you absolutely have to floor it, at least, not as many as when out on the track ^_^
I dont know why alot of people doubt the H22 can produce 300hp without heavy modification. Most stock engines can take 7-8lbs of boost without excessive wear, and an H22 on 8psi can sure as hell get close to 300hp. My friend boosted his civic's D16 to 18psi, and it put down 340hp on the dyno, it was a stock block though so it started to burn oil after 6 months of hard driving, still ran but smoked a bit of oil. Just dont go crazy with boost and your engine will remain reliable and last for a long time.
Also, notice all the stock boosted engines available, the subaru ej25, saab's are generally boosted, lots of older volvo engines are turbocharged (I pulled two tubos off of two 740's), some mercedes engines (I pulled another turbo from a 300d, also consider that all the turbos I pulled were on cars with over 200k miles on em, all wastegates at 7psi,) pt cruisers (some models), dodge srt4's, etc. A little boost is good, too much boost will start to burn out your motor.
Keep in mind there is a certain powerband that a turbo produces, generally at higher rpm's the engine produces more boost, but that depends on how big the turbo is, as well as the size of the engine powering it.
A N/A 300hp motor will outrun a turbo motor with 300hp because of the powerband, a turbo motor will take time to build boost and likely only untill 4krpm, and a N/A motor will get power sooner and quicker.
Building an H22 to get 300hp N/A will take a bit of work, needs sleeves, pistons, rings, rods, valves, ITB's, headers, springs, cams, all of which are expensive. Considering the cost of a turbo kit vs the N/A tune, id definitely go with a turbo.
Bisi-Moto created an F22a SOHC Non-VTEC engine that makes over 350hp (read in super street mag), dropped the motor into a honda insight, and is running 9.6 second quarter miles. Its heavily modified though, and since its got a 17:1 compression ratio you have to run high octane race gas. The setup is expensive though, but his is extremely quick for its class.
