Best turbo upgrade for an automatic transmission

03 wrx auto: I have a Vishnu stg 1 and was wondering what would be the best turbo upgrade for an auto when I get the Vishnu stg 2. I would like the fastest spooling turbo I can get, to help out the auto+lag problem.

Thanks for any input you might have.

stay where you are. i had a automatic wrx and went from stock to a vf34 setup. the lag was about the same. after a while, i kept my full exhaust and went back to the stock turbo. spool up was a heck of a lot quicker, and i only lost about 30whp.

0-60 times will be about the same with either turbo. the vf34 won't outrun the stock turbo until about 50mph, but the stock turbo will get you there a hell of a lot quicker.

I just had a VF30 put in and it's fantastic. Yeah, the lag does suck.

What else do you have done? What numbers did you get on the dyno?

I have the COBB stage 2.5 with a front mount. I pretty much have all the basic bolt-ons. I've never dynoed my car but it pulls very hard after 3800RPMS.

Whatever. Hey sloppyjoe, try VF35. Those thing are best for us auto guys but those are a little hard to find.

Hey, I'm allowed to make fun, my 01 RS is a 4EAT. Personally, I would look at valvebody upgrades and whatnot, to make sure that any extra power that you make is put to the ground. Upgrades on a 4EAT car just don't have the same impact as on a manual tranny car, since the transmission is designed for a specific torque curve.

Just a thought.

Cool, thanks for all the replies. How does a 35 compare/differ from a 34? Faster spool, less top-end, ball-bearing, etc.

That would be the worst upgrade in my case. It is hard to use a clutch pedal when your legs don't work.

Well the car is all done! Vishnu stg 2.; I went with the vf-34. On Shiv's dino I was able to get 235whp; Shiv is going to post the dyno plot in his section of the forum. Now I just need a tc, and I think I will be cured of my modding illness... maybe.

I also have JDM HID's and Volk GTC's on the way! Again. thanks for all the input.
