Liberty GT Auto - Turbo upgrade suggestions please

[PoidaGT]

What Turbo upgrade do you guys suggest for 2007 Liberty GT auto?
I currently have an Invidia Turbo back exhaust, AVO Top mount intercooler and MRT XB tune.
The car is a daily driver and have no plans to take it on the track.

Is the AVO 380 V2 ball bearing Turbo the best upgrade?

Kando TD05 20G 8cm

Thanks for the advice Jim

Is Kando and Kinugawa the same company?

Are they a laggy compared to the standard turbo or they similar?

I see they are a journal bearing turbo not ball bearing and obviously the price is reflective of that.

Are the ball bearing turbo's worth the extra coin?

Do you suggest just buying from Ebay?

No idea.

Can't have power with out lag. but it's only another 500-2000 rpm depending on what turbo and your setup. FMIC vs TMIC, ETC.

I have a HKS GT2530 on my 2.0gt auto. Makes 200kwatw on the road. The Auto trans starts slipping once you get to 200kw.
It made 212kwatw on a manual. Both running 18psi.

Do you suggest just buying from Ebay?
I have seen some good prices on eBay for the Kando and Kinugawa turbo's. Have also seen some good pricing on Garett, HKS ETC brand turbo's right here on the forum. You can get some crazy cheap prices around here.

kando & kinugawa are the same...

get the td05 18g 8cm

if you wanna get a 20g get the CBRD bbk turbo....sweet turbo that Pro Speed Racing has - http://www.prospeedracing.com.au/produc ... %252d.html

cheers jack

Thanks for your suggestions guys.

I really want a good all rounder that spools up as quick as possible, better mid range and top end however i don't want to sacrafice low end torque for big HP.

I'm also not sure how much the auto transmission restricts bigger horse power applications.

Does anyone know what the previously suggested Turbo's are like at lower rev ranges?

CBRD bbk turbo 20G

I have done research on this and spoken to a lot of people as I'm going to be upgrading the turbo on a 2.5 auto as well.

You cannot get better mid range and top end from an aftermarket turbo without sacrificing the low end a little. The bigger turbo, the bigger the sacrifice, but the bigger the smile on your face once it hits full boost

Auto trans restricts high HP big time. You won't get the power you want out of an auto, period. Once you come to terms with that fact then you'll be fine

I'd suggest also looking at the blouch turbos for liberty, the Blouch 380xt and 440xt in particular as they are a direct bolt on upgrade for our cars.

I am currently in the process of upgrading the turbo on my car.

I've ended up going with a Subaru OEM IHI VF52.

This is the current turbo on the MY09 onwards WRX and provides good low end driveability characteristics whilst affording about a 25% increase in power.

It's an exact bolt on including hoses etc.

I'm hoping to get about 230awkw with this setup and supporting mods with 18psi boost.

This is also a cost effective option. PM me for pricing etc.

Hope this helps

The VF52 is a great turbo. Heaps of low down punch. But I'm not sure it's top end it big enough to make 230. It's a stock turbo, so it's primary function is to come on boost ASAP lol. I am no god of turbo's or anything like phat. I just did way to much reading when I was turbo shopping 6 months ago.

The BBK 20G is a great tuebo. Have heard great things from the evo boys that seam to put that turbo on a stand and worship it lol. BBK 20G normaly makes around 220-250 depending on your setup and supporting mods.

Really depends what power your wanting though? Remembering the auto trans won't take anything past 200kw. So the 18G would be a better option in a Auto. 500 quIcker spooling, but will only make 190-220 depending on your setup and supporting mods. BBK also make a 18g.

Speak to jack about the 18g turbo's if you want more info. Both BBK and Kando make one. Jack made around 210kwatw in his 2.5gt manual with one. (dont quote me on that, sorry if you made more or less than 210 jack.)

Correct me if I am wrong but the td0518G flows approx 600cfm at 14.7psi the VF 52 etc are only good for approx 430cfm. Therefore more ability to make power with the TD05

Vf 52 will top out at 200kw..... any more then that and you shorten its life

[Kekotic]

Tony, he meant a pulse dyno 230kw.

Also any idea on how it would go when you try E85 on the VF52? If you say you can't push it past 200 without shortening it's lifespan, E85 would sort of get around that a little or no?

Sorry guys if you feel these figures are unattainable with a VF52. These were figures provided by owners of 07 or 08 WRX's I've spoken to at various WRX club meets running the VF52 setup with supporting mods. A few are getting 240awkws from their rexxies. At this level it would seem the injectors are the major limiting factor by all accounts. I have no idea on the boost settings or dyno reliability so can't comment. I sure these guys would have no reason to fudge figures.

Bruce if you read correctly, the guy saying he had 240kw atw was saying he was running stock injectors. However he runs a completely different turbo to a VF52.

I've spoken to other people as well Kieran. Not only forum posters. I can forward you emails from them if you wish. And they are people whose opinion we both respect.
