I think the 16g is more like the S01, not sure.

But there are a bunch of different 16gs.

GTPS01 = TD05 (7cm housing) /16G
GTPS02 = TD05 (8cm housing) / 20G
GTPS03 = TD06SL2 (8cm housing) / 20G

S01 and S02 use different exhaust housings. TD06SL2 is a completely different beast to the regular TD06. It was designed by Mitsubishi for Trust and has a very light wheel so spools up very quickly.

Its a 500hp rated turbo which is quite large for a WRX, even if it is 2.5lt!

As long as you have other things like a full exhaust, intercooler upgrade, and have upgraded your fuel system, then its probably ok!

400WHP is a lot, we over here dont run that sort of power in a standard STi engine.. we would rebuild it!

So you've created/overlayed that map yourself? It doesn't look like it is aligned properly.

It would be a lagmonster on the 2ltr, probably spooling at about 5000rpm or thereabouts. Tough to say, it has been a while since I looked at this stuff.

The GT2871 is probably the limit on the 2ltr unless its a dedicated track car with an 8500 rev limit.

Hey Clutchy
I was looking on the Garret web site and saw that the GT3271 (71mm, 52 Trim, 0.50A/R) appears to have "twin scroll" inlet which is like the APS TSR except way smaller. It will need new headers to run it with exhaust gases pulsing from each cylinder bank.
What are your thoughts?

I agree :) It will need new headers/uppipe/dump/sump.

What HP is it rated at??

Wow that's like a twin scroll AVO400s, you'd also need an external wastegate though so things are starting to get a bit expensive for the return, as compared to going with a JDM twin scroll setup.

I reckon a 450hp twin scroll would be the bees knees (no pun intended) on a 2ltr.

Only with a larger turbine frame size, inducer diameter, and turbine wheel size.
Shouldn't it be bigger than a 28 size frame (from the 400s)?

Hmm yeah thats the odd thing, its definitely bigger but only has the 420hp rating. The AVO400s is supposed to be 400hp and the 400L is supposed to be 440, but by rights this Garrett should be in the 450 range. If so, its probably a great turbo for the 2ltr if you want to go down the path of the custom fab.

I can't comment though, I've never seen or played with a real garret setup.

You know you want to bumblebee! :)

Here's a twin scroll set up using the GT35R for a 2lt wrx/STi:
It appears the T4 inlet is for the twin scroll Garrett's

This turbo is rated at 650hp
Hmm :twisted:

That looks very nice.

I take it that's a US site for a US spec STi? The photo's on the site don't really show whether that's an Aus spec STi or a US one.

Apparently GCG Turbo's are releasing a rotated mount setup and it's currently under testing and development and they're talking to a few workshops about it too - pricing is yet to be announced on the kit, but hopefully they'll design it for a 2.0l as well as the 2.5's :)

From here:
http://forums.nasioc.com/forums/showthr ... ?t=1216577

VF24 map if anybody is interested :P

VF22 map

The VF22 map I posted is legitimate. It's the same map as the VF34 would be and almost the same map as the VF30 and VF39 would be. The difference is the ball bearing construction hence the speed line at 1.4~2.0 Pr. Other than that the maps are going to be the same.

RHF55 map
The VF39, VF39,VF34,VF22 (all RHF55 series)

The VF34 is a ball bearing center cratridge so it's goign to have a similar spool characteristic as the VF22 down low. Actual flow like I said is going to be very similar between all of them. The difference is going to be:

1) Ball bearing center cartridge vs floating bearing

2) P17, P18, P20 housings. I'd like to see the actual visual diffence if any of you have pictures of them disassembled?

Boys has anyone looked at the TD05H -Super 16G.
I have got one coming from the USA.
From doing a bit of reading on the USA web pages this is one of the best turbos they say for a 2L.

Not a lot of guys running this in AUS. Any feedback?
Somes guys run 11's with stock engine in the USA on a 2L.
