ok i've done some research and only found one thread in here but it was on a built h22a.i've also found that most of the us guys are using a t3/t4 type turbo.
so my question is what kind of turbo would you guys recommend for me? keeping in mind i want good low down response, decent power throughout the rev range and it to be running closest to it's best efficiency at around 7 psi.
also if you could include prices i may be looking at paying and whether thats a used or new price.
thanks.:)
very good low down, go with a GT28RS or if you want a little more power but power a little later than the 28 a GT30R wouldnt be bad
GT28RS can be had around the 1600 mark new, cant remember what the GT30R goes for...around 2k i think
what about a t3/t04e???
personally for a 2.2l, u can afford a bigger turbo. id go GT30 atleast. (pending if u are gonna push around 1bar of boost) killer mid and topend, i cant see a reason the dohc vtec head wouldnt spool it fairly quik! 3-4k!
note: any of the turbos mentioned can have as many configurations as u like. differnet covers will produce different results. for example a t3/t4 hyrbid can be made to work well with a 1.6l d-series (48. a/r) but can also provide good power for a larger 3l engine with a different config.
For a 2.2liter engine.....and you want to get it for cheap...why not a S15 turbo?
And 7psi is just the beginning of the efficiency range of most turbos nowadays...unless your talking about the tiny ones off jap micro cars....eg honda city turbo.. The S15 turbo runs at 8psi standard and can go up to 17psi if needed but only at short bursts. Any higher boost and you will need to change to another turbo. The GT28RS or disco potato as its commonly known is just a little bit better then the s15 turbo in terms of the top end. 320hp vs 300hp. It has even better response though.
If your really keen though....get a hks 25/30 turbo.....best street turbo. Exxy though. For a cheaper option, GT25/30 . Same turbo essenstially but without the custom housings that hks add to theirs....which helps its spool up time.
thanks for your info guys but i dont plan to do any internal work so i wont be going over 8psi max. so i am after a turbo that will be efficient at that level. im not looking for something that can be turned up to say 15psi as i wont be needing it. i want a turbo to match my set application, that way i can try and get the most efficient setup and power on low boost.
oh also i can get my hands on a manifold to fit any t3 type turbo so anyone got any recommendations for that because i can save some money here but so i am looking probably at a t3/to4e but what trim size for my application would work the best???
wow.. been waiting for this along time..
MR-VTEC. u got the same idea as me..
i been asking round.. a T28 from a S14 or a T28BB*ball bearing* is pretty alright already.. SPool is smooth as.. also sufficient if running about 7-8 PSI
dam guys..
MR-VTEC.. are u gonna buy a Manifold or custom it?
cause i need one as well
well it depends on what turbo i go with, as to whether i'll go a custom manifold or just buy one. alot of the us guys use a t3/t4 type turbo on their setups so there are a few off the shelf manifolds you can get like 'maxrev' for example. but if i dont go that way i'll have to get one custom made.Quote:

If you get a t3/t4 turbo you would never use it to its best ability at 7psi and so you might be wasting a bit of money in getting one. It does give you the head room to later up the boost if you wanted more power in the future.
With thet3/t4 you should get the smallest housings possible.
get a 60-1 type turbo with either .63 or .86 rear depending on what power u are chasing.
will support 600hp and should work a treat.
even when i was running the car in, i had it at 8psi with no ignition timing on the microtech and only revved to 6k it still made 175hp and thats on lower compression then a standard h22a.
so if u decide to run about 8psi, i dont see why u wouldn't make 150fwkw's.
with that type of power u'll be surprising alot of turbo cars.
ive been wanting to sell my old turbo/manifold/computer for a while but sooo many people talk so much and dont buy...
BUT here goes again...
ct26 turbo (hiflowed slightly bigger than a T04) done less than 5000km can handle 20+ psi
custom manifold to suit h22a + turbo (ceramic coated)
microtech LT8
FOR SALE $3000
i was running this set up with intercooler and a 2 1/4 exhaust. response down low is amazing. also with stock internals produced 150 kw atw @ 10 psi.
let me know if your serious!
