I have stock turbo's in my supra tt atm. I would like to upgrade them to something better. I dont have any fuel line upgrades yet, is that something I should do first? Turbo lag time gets on my nerves, so I was thinking about a Twin Turbo upgrade setup. I was thinking of the HKS GT 2835 Twin Kit, or the Blitz KT3 Twin Turbo Kit, what do you recommend? Or is there a more powerful Single Turbo system with neglegable spool time? What Brand/Kit has everyone had the best experience with? or one that I should stay away from?

Thanks

twin turbos kits are very very expensive

best quick spool up time kits are the sp57,sp60
phrstreet kit or phr stage one

for more power sp63 .phrstage 2
or the greddy t-78

all good setups!

T-78 is the best money can buy. even without fuel yet.

I was thinking about the Greddy T-88, any experience with this turbo kit?

Keep in mind that my car is also auto, so the greddy t-series dont really apply to me unless i invest into a stall converter as well. thats why i was thinking of the twin hks gt's

If you were to go with HKS twins I would not reccomend the 2835's. A local supra owner has them on his 6spd and didn't get good power until over 5k rpm. With some of the smaller turbos it would be a real good set up. There was a thread in MKIV tech that gave some specs on the different sizes available from hks. If lag is really a big deal you may consider the sp57-sp60 or one of the smaller PHR kits. What kind of power do you want? That is what will determine the lag.

SP63 all the way. It is capable of 650rwhp (it has made over 680rwhp with cams and an intake) and it spools like stock twins in TTC. You can see my dyno chart comparing the SP63 to stock twins at www.geocities.com/steve_jarvis_me Keep in mind that I am currently running the stock MAF and fuel system.

Hope this helps, Steve

I can vouche for the SP57.....It spools really fast. My friend has an SP57 kit and he absolutely loves it. I am planning on going single in a couple of months and the SP57 is the setup that I am going with.

Go with the SP63. Wouldn't be fun driving an auto with HKS twins. Jus my 2 cents

you know... I need this question answered for myself... why do you need to upgrade to a higher stall torque converter??

You have to remember to take into account the power lost due to the auto tranny. If you're looking for 600-650rwhp, you will have to go with a pretty big turbo. I have the SP63 on my '94 auto Supra. I am going to go dyno it soon and see what I get, but I'm not expecting anything over ~550rwhp. The highest I've heard on a SP63 auto is ~580rwhp as opposed to ~680rwhp for a 6sp. I'm not sure what %HP you lose from the auto tranny, but it sounds like alot. Anyone know?

WEIYAN8, i have seen your car on to4r.com, i noticed that you switched from a to4r to your current setup..my question is, how was your spool up on the to4r w/ the auto vs. the sp kit, i too have an auto supra and i am trying to find the best setup, please help, i would greatly appreciate your input...

if you really want a twin setup than Garrett GT30's may do well for you. From what they say on PHR they spool a lot faster than the HKS twins.

Garrett GT Turbos = HKS GT Turbos

Garrett less expensive.
HKS more expensive.

True true.. even guys from HKS say that their turbos have Garrett turbines, their housings are different though

Yes sir, but you are right Garrett would be just as wise a choice for anyone looking to go twin. Just stay away from 2835 or 2835R size turbos and stick around 2540R with a custom twin setup
