good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

looking for some ideas for a good turbo for a jdm h22a stock internals boostin 6-8 psi daily driver, need something spool up quick and carry to top...will the below turbo get me what I am lookin for?


T3 super 60 .63 AR turbine .60 AR compressor 60 trim ya or na?

looking to get 275 whp @ 7 psi

Should be fine, but its not going to like being spun up in the higher rpms. Might be choking it at that point, not sure because I don't have a map for it on an H22, but maybe like a 50 trim t3/t04b if packaging is tight or the t3/t04e if space isn't a big issue. Not sure of space because you didn't name a chassis....

CRX space is an issue...

the t04b housing will give you a bit more clearance in that case, even though it is slightly older technology wise. Shouldn't be hard to get a used one for like $300-$350 or so. Or just pick up one of those tbird turbos and swap it to a t04b compressor.

Just remember not to rev that h22 that high. It doesn't like it hhahah

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

I may be a little off here, but I don't think that turbo will make that much power at only 7 psi....it seems a little small. If you could have anything you want, I would say to go with a stage 3 wheel on the turbine, and run a T4 compressor instead of that little super 60 T3. But, hey, we don't always get the choice. It will probly feel pretty good, but it's going to start to bottleneck at the top end. Revving high up alot is going to overspin that turbo and really shorten the life of it alot...

your goals contradict themselves.
275 hp shouldnt be much of an issue with an h22. but if you want topend or something that will make power till redline, that turbo is way too small.
id get at least a t3/t4 60 trim and run a lower boost level if you want only 275 hp with an h22. that motor is just way too big for that turbo.

i've got a H on boost with t3/t4e .60 .63 57trim and i see full boost around 3500, running 6lbs. I threw in my manual boost controller in and saw 15lbs half throttle come in at 3500. i dont think u will be satisfied with just a t3, it also leaves you with no room play with. just my .02

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

yup, that turbo is ------- small for a 2.2.

that turbo on a sohc f22 spooled up 10psi before 3k and pulls till 6k, dont know if it was dying off becuase it still pulled pretty hard.

get a stage 3 wheel on that turbine, and a t4 compressor and you'll be golden.

I appreciate the help guys...yes I went with a Garett T3/T4 57 trim .63 hotside pretty much what u guys recommended as well after talkin to a few techs...

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

you need one like this, with a small t4 twin scroll housing.

it would be perfect. oh im selling it btw.

newbie here too :S

I got the same engine and I'm looking for a turbo from a production car that will meet my requirements?

Engine: H22a (stock internals)
Chassis: Prelude 4th gen
Max revs: 7500rpm

Power goal: 270-300hp (don't require silly hp numbers)
Pressure: 6-7psi

I just do not know which turbo (from a production car) to look for. :-(

Thank you in advance
K

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

your gonna need more that 6-7psi to make 300hp

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

You're gonna get raped :3

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

Even if you did get a turbo that hit 300hp at 6-7 psi, you'd probably be bouncing off the surge line due to the sheer cfm flow. A lower cfm turbo with a slightly higher boost pressure would be more driver-friendly. At the very least make sure it has a .63 a/r hot side. Check out my post on turbo101, 102, and 103...it tells you exactly how to figure out what's the best size turbo for your application.

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

thanks for all the replies.

as you know, i'm quite new at this :-(

I had a look at the FAQ section but the list of turbos there seem to be running at 15-20psi. I only want a mild increase in power (240-270hp @ 6-7psi ; if 300hp is not achievable safely on a 6-7psi of boost).

I also do not know from which production car I should take a turbo from (once I've found the right turbo for my application).

Sorry if it's a noob question, but the calculations are quite daunting at first glance. I will research on this more, but please answer the above for the meantime. Thanks!

just to be clear, I only want to run relatively low boost pressure (8psi MAX) because I have no plans on building the engine internally just yet (have heard 6-8psi is the safe boost level a stock H22a can take), I will have a spare engine for that later on.

i seen h22 ringlands blow on only 5 psi b4

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

:-(

Maybe badly tuned?

Cuz I've heard of many H22's with stock internals on low boost and daily driven still going strong?

Anyways, any input on my query? :D

you are querry !

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

That's a pretty generalized statement, and I absolutely hate it when people throw psi numbers around like they know something about it. 6-8psi out of what turbo is what the answer should be more or less. A turbo that flows 350cfm at 12psi isn't going to be nearly as rough on a motor as a turbo that flows 650cfm at 6psi. See where I'm going with this? People used to tell me I could only run a max of 8 psi safely on my d16z6...I ran 14 and it survived for over a year until I swapped to a b-series. I've run LS's at 16-18psi, b16a's at 16psi, all of which I was told never to run that high of a psi on. Granted, higher psi's do increase cylinder pressure, and in that case a good solid tune is on order, because even a higher psi number than what people tell you is "safe" is still nothing compared to the cylinder pressure produced from detonation.

Cliff Notes:
People are full of ----, don't listen to all of them.
People who blew their motor's going over 6-8 psi probably did so because of shitty tuning and detonation.

Re: good turbo for 6-8 psi on stock internal JDM H22A?!? Help Meee
 

get a big turbo, run low boost, and tune the ---- out it. oh, and dont rape it every day.


thats the best way to not blow up the h22.

I've seen stock h22's go past 400whp. The longest ive seen one last is about 6 months. bearings went bye bye.
