New Turbo For Rb22

[Justa32]

well my turbos giving as much as it can give its an apexi ax53b70, im looking at a new turbo ive had a few in mind specialy the hks 3037s pro, garrett 3071r and maybe the 3076.. would a gt35 b to big? im looking to break into the 11 second mark any help would b good thanx, the engine also has a 12port head, tomei poncams and a few other goodies

[R31Nismoid]

What "few" other goodies??

A GT35 is too big for a 2.2ltrs far as i see it, far too big... GT35 is 350rwkw style, 30+ psi easily... on a 2.2 with a head that flows like a 2" exhaust

So you'll run into all sorts of drama's there.

Even a 3037 is too be, get a 2835 or similar IMO. With decent tyres and a good driver 11's shouldnt be a problem

ive had a look at the 2835 but its not rated at that much more ps than the turbo in there at the moment.. generaly im aiming for 400rwhp and if it breaks 11's it would b nice. few other goodies meaning just off the top of my head forgies, cams, powerfc, fuel pump, injectors, head gasket.. i dont mind abit of lag but i dont want sumthing hitting full boost at 6k anything around 4 - 4.5 is fine by me

[R31Nismoid]

GT35 would be 6k easily mate.

Much bigger than what you have on there now and your getting into the bad response corner of the turbo earth for RB20's (even if its 2.2)

[Justa32]

yeh gt35 was a long shot im more focused on the 30** turbos

gt3540r with a 63 rear would be reasonable on a 2.2..

my personal recommendation is the garret gt3040r with a .82 rear. on my 20 with hks cams and a .63 rear housed 3040 it makes full boost around 3.5-4k.

I have a GT3076R on my rb24 i am building, I am looking at selling it for something around the GT35 - GT40 size to handel 450kw atw but would be perfect for a rb22

IMO a GT3071 with a .63 ex housing will see very close to 300rwkw, with the best response you can hope for.

How much power are you getting from the AX53B70 again? Was around 220rwkw yeah? If so that sounds alittle low especially with mods you have like cams and headwork and a 2.2L...i think guys have pushed numbers close to the mid 200s...i could be wrong though...but if thats true...then that sounds like there are definitlely issues or restrictions in your system that should be sorted out...

I had a look at your dyno graph and you're making less power with the same response as my 2535...the AX53B70 is rated higher than the 2535...plus you have headwork and a 2.2L...it probably shows that theres a fair bit more to be had from your setup...

If you do want to upgrade though...i think a 2835 or maybe a td06 with 8cm housing would be the go for around 250+ rwkw...i'm starting a hybrid rb22 build too and might consider a turbo upgrade too at the same time as my 2535 might be getting alittle tired...and if so i'll probably go with the 2835...

MY RB24 with GT3076r .63 IW - is making 262rwkw atm... i've got cams on the way which may push it a bit higher. I reackon this turbo with .82 exhaust housing should see 300rwkw...

IMO a GT3071 with a .63 ex housing will see very close to 300rwkw, with the best response you can hope for.

I think your right mate.

This is the option I would be going for if I was chasing 300rwkw on an RB22. The 2.2l isn't going to have that much exhaust flow that it will cause a restriction and limit power with a 0.63 a/r rear housing, and this should still be pretty responsive.

limpus the tune was done in perth by a fairly known tuner and they said that there pulled as much out of it as they could, the other other way im going to make more power is to get a bigger turbo.. i mite go 2 another tuner and see wot they have to say because im pretty certain that it can get 320 - 330rwhp... ad4m ive spoken to u abit on antilag, that GT3076R murrayis is talking about u rkn that would suit my engine? murrayis what housing is the turbo?

[AD4M]

GT3076R would be fine man!

not to long ago a dude in perth had his tuned running that turb on a std rb20 with hks cams,plazmaman plenum,6boost mani, turbo smart 48mm gate and all the usual supporting mods and went 358rwhp@20psi... and the way it made the power was so linear and smooth, if i didnt already have the 3040 it definatly would have been my pick!

i cant remember for the life of me what rear housing it was but if you need to know more shoot r32rookie on antilag a pm.
