well I wasn't aware of how you felt when it came to buying parts physically in front of you.

but it's good your happy with your power on the turbo you wanted, boost does look good though.
You do realize that the 20GXT has a 47lbs/min wheel and in the same configuration as the CXR500 costs roughly the same price!?! Also, the CXR500 has a 44 lbs/min wheel that only flows 47 lbs/min with porting.

Bump for good thread, I actually got my 20g xt the first week it came out so i paid a good 1500 for mine. i don't have any dyno sheets or anything. But i do have a few ?s First i will just mention the mods. 07 wrx tr, perrin fmic, 850cc dw, perrin inlet, invidia dp/full exhaust, perrin fuel rails, perrin uppipe, perrin intake, blouch 20g xt, ppg gears, Cobb AP, Well im pretty sure thats it. so he is my ? for ya. Befor i put the ppg gears,20g and the fuel rails/ injectors i raced a friend of mine that has a 04 m3, we were dead even from 2 to 4 and then his top end kinda had me. BUT after the turbo upgrades and everything getting wore in witch i made sure to do lol, we raced again and i barley had a car on him i would of said it was the driving but its not like i haven't raced him before so i was able to compare. So i guess my ? is What could be the problem. Sadly after 2000 miles of having the new turbo and gears my tranny broke on my again, this is the 3 time around, 1st time was covered under warranty the 2nd time i broke first gear so i went ahead and got the ppg gears, 3rd time witch was 3 weeks ago now, i was on my way to pick up a carbon fiber hood (CW II Style) from a local in town everything was fine on the way there didn't even go over 4g rpms, I literally step out of the car for no more than 30 sec just for the guy to tell me to pull it up to put the hood on. got back in the car and my shifter was stuck in neutral not only that but the neutral position was actually first gear,also the only gear it would go in was reverse but when i was able to do that the car acted like it was in first and reverse at the same time, so it was go nowhere. so after paying the guy 300 for the hood i drove my ass home in first gear for a good hour at 15mph. So i guess it came out to be 2?s witch im sorry i ended up venting lol Thanks guys let me know I could really use some input on this. John

Adding porting to a turbine housing will not add 3lbs per min of flow to the compressor wheel....

Just bought a Process West TMIC this past weekend, will have my 20G turbo installed, with a custom 3" CAI, hope I like mine as well. Will post up results this weekend getting tuned !!!!!!!!!

The throttle response is better and it has Blouch reliability so it's the perfect turbo for that niche.

As you can see by the Dyno i opted for a "protect-the-tranny" route and instructed him to keep the torque below 320 lb-ft. The way we were going with the tune on e85, we could have easily seen over 400 whp/ lb-ft on the 750's. So to answer your question, I was the limiting factor, not the injectors nor the Intercooler.

I do plan on taking it further once i get to a place where it's financially safe enough for me to start blowing things up.

So question. I'm new to all this and I was wondering what would be the biggest difference between the 8cm turbine housing and 10cm? Any suggestions on which one to get?

Default 20gxt or bigger?

So I'm completely new to NASIOC and it seems like there's a million forums and posts, but I'm gonna add another anyways. I'm rebuilding my 2002 WRX and I was looking to get into the AWD/ Subaru scene. Existing mods on my car include;
- Mishsimoto aluminum radiator
- HKS blow off valve
- AEM intake
- ACT clutch with modified street disk
- Prostreet flywheel
- HKS downpipe
- HKS Exhaust
- Konig Carbon fiber rims 18"

Dropped the car off yesterday and the new mods being installed are;
-
Built EJ257 short block
New STI crank, race ACL main and rod bearings, eagle rods, CP
pistions and rings - 8.2 comp ratio, new rear main seal and case
hardware, including assembly
Blouch TD06H-20GXT Billet 8cm^2
GrimmSpeed Ceramic Coated Uppipe
GrimmSpeed TGV deletes - with core charge
TurboXS Top Mount Intercooler
DeatschWerks Fuel Injectors Top Feed 850cc
COBB Tuning AccessPORT Subaru 2.0L Turbo
Walbro Fuel Pump 255Lph 1
Walbro Installation Kit Subaru WRX / STI 2002-2007
Kelford Cams
Perrin crank pulley
BG lowering springs 1 1/2"

Car will be initially tuned to 300WHP until I can get the drivetrain up to par. The plan is to eventually get 360whp - 380whp on 93 and over 400 on racegas.
Anybody have any other reccomendations of what I should do while she's apart?????

ELH, EWG, and a high reading dyno are the only ways you'll see 360-380whp on pump gas.

I had an FP TD06 8cm 20g in the past. Whats the main difference with this new 20g other than the Billet wheel? Shouldn't it spool the same as before?

Spools slower but holds boost better. Behaves close to an FP Green without all of the having-to-deal-with-FP shenanigans.

Thanks

2 fold

- 10cm vs 8cm
- compressor flows more and if you're flowing more the turbine has to work more.

I'm just telling you the case. My 8cm^2 comes-to at like 3950. Most 20G's i've been around were coming to life before that. But it also behave likes a larger turbo in the sense that it's very smooth and holds really well.

Well...in the world of 20g's there are so many different variants (td05,td06,7cm,8cm, 2.4" inlet, 3" inlet, sl2 wheels, xtr wheels) that comparing plots of "20gs" becomes quite difficult.......not to mention the effects of which headers, int or ext wg, ebcs tuning, mbc, avcs tuning, fuel, elevation, etc etc. can all have on spool characteristics.

Most likely.....you don't get something for nothing. The compressor flows more air so the turbine needs more exhaust gases to spin it

The billet wheel is also lighter than the old steel wheel. And its just a tad bigger, from 44lb max flow to 47lb max flow.

Hmmm, never thought of it like that. I suppose it's pretty damn close yeah. The later spool with the xt vs. The non xt is minimal. Something like 150-200 rpm later. It's likely you won't notice a difference unless you're comparing the 2 dyno charts. The gains uptop seem to be worth the slightly later spool.

I think you need a ewg for sure. I run a similar setup with a lot of meth and make in the 420 range. It'd not hard to do really, and im using the regular blouch td06 8cm w/3" inlet.
