i'd like to know what's the best turbo with the least lag for an h22a motor.

 

it depends on how much power you wanna make.

 

least lag = gt12. But will it make any power?? i doubt it. you need to restate your question. more like " i wanna make xxx amount of power, which turbo will meet my goal with the least amount of lag?"

 

sorry...let me rephrase then. i'm posting this for my friend, his goal is to reach 300hp. which turbo would be the best one for this goal with the least amount of lag?

 

i believe it's the greddy 18g( whatever one comes in the greddy prelude kit)

 

i would go with a larger t3/t4 hybrid.. like a 60trim, it will make 300whp easy and still spool around 4k.. or if your looking to make more power(wich everyone does) just go big, if you can stand your turbo spooling after 5k in first, and you will be able to drive without boosting.. realy ther is no such thing as to big, even more so since the wonder of anti lagg...

 

the 18G is not the right turbo for this application...You will be out of your effiecency range and essentially be blowing hot air into your motor...Greddy did not use the right turbo in their kit.

If 25 people respond to this thread, you are going to get 25 different answers...The correct thing to do it research the turbos specs, how to read them, and talk to the "right" people. Look at other prelude turbo set-ups and go from there. A good place to start is the "Official prelude turbo thread" in the prelude forum.

THis comes from someone with a 300 hp stock h22

 

and realy there is so much more than just the turbo... it can also depend on the eficancy of your entire setup... the main part is tuning, you could run a awsome turbo, and only make an extra 50 hp at 10 psi... it just goes on... the best thing to do is look at your goals how you drive and what you think is best for you(or friend) just don't skimp out on miner details, you will regret it after..

seems to me it should take about 12-15lbs to get in that range, and i find it hard to believe it's out of it's effeciency that low. i thought it was above 18lbs?

 

i did the calculations for the Pressure Ratio and Correct Mass Flow for a 2.2L since and t3 super 60 looked very effecient and should hit 300hp easily.

i went with a t3/to4e 57trim. got it for a great price and not too shabby in the effeciency zone as well.

THis is on a b16 not an h22, it makes a big difference.

 

An example would be one of the ball bearing GT30s. They do cost more than the units with conventional bearings and can't be rebuilt.
You would get around 300 whp @ 9 to 10 psi. It starts building boost almost immediately even in the 2000 rpm area. Great daily driver!
There are other less expensive options as mentioned earlier.

 

gt35 e or r

The problem with the Greddy 18G for the Prelude kit is not the turbo itself, but the exhaust outlet elbow on the turbo. It's restrictive and prevents the H22 from coming close to achieving 300 whp.

 

Its also the turbo itself, the adapter elbow was slightly restrictive, but it was the turbo and downpipe PAST the adapter that is part of the problem.

 

I have a GT35R on my H22. You can definately make around 300whp on a setup like that. Lag? There's a bit of lag but I built my motor with 9:1 comp pistons so that maybe the cause of my lag. I'd go GT32RS or something similar.

 

Well first of all what ET's/mph is he looking for?

 

i have a 60trim turbo
makes 320lbft of tq @ 4200rpm

 

How about a t360-1? How well does that spool up? Is it a good choice for an h22?

 

My friend. I hate to sound like this, for I'm normally the nicest guy around here. But we aren't mind readers. We don't know what kind of power you're looking for in the WAY you're looking for. Instead of getting about 62342023 opinions on this board on maybe a bandwagon solution with most of us spitting out what worked for us, you need to calm down, research, check some other setups around this board and other boards to find out what it is that you're trying to accomplish. Hell, find some other H22 motors that are boosted and ride/drive, or get some other opinions from actual owners.

Stop this guessing and asking, and figure out slowly and sure about what you're trying to accomplish. A turbo can't do everything, but it can do a lot..

I'm sorry if I seem rather blunt. This is about the 3rd thread on H22 turbo questions I've seen in one week.. Look BEFORE you ask.

 

Some of us (H22) owners still like to toss opinions around. Shodans advice is good. keep on looking, reading etc. You'll find some setups that are very similar to what you will want. Good luck.
