Default I have a 4EAT... don't hate me

I have an 05 WRX automatic. Problem is, I don't want to "launch" it, but I would like to get to the high 14's from pretty much just flooring it from the get-go.

Would a Cobb stage I be enough for this you think? Or do I need more?

For reference, someone on WRXforums said that he ran a 15.7 just flooring an automatic.


Note: I probably will never actually drag race, I just want to be "equal" to a stock 5MT in terms of speed.

Sell it and get a 5 speed...or just neutral drop it (just kidding) We don't hate you for getting an automatic, but it really ought to be a crime.

If you have a 4EAT, get a high stall torque converter, tranny cooler, synthetic ATF, a valve body hydrosystem recalibration and maybe a tranny temp gauge.

Levelten for the valvebody mod

Protorque for the TC

Redline synthetic ATF

Tranny cooler in the case a hayden 403

Don't let the 5MT people get you down, They don't know what keeping boost between shifts even means.

Thanks for the links, very useful as I have trouble finding truly reliable upgrades. If I ever get money I'll look up some of those.


But yes you guys are right. A standard shift would solve all my problems.

I think there are some definate benfits to getting an auto. Primarily, traffic driving. Driving in traffic for more than an hour is hell in a 5mt. Also, for autocross racing, the taller 1st gear means you dont have to shift as often. And for a consistant launch, just hold down the brake and floor it, then let off the brake when its time to go. Easy as that. (Obviously dont hold the car for too long.) Also, the autotranny is stronger than the MT.

I agree with the aformentioned mods. The tranny cooler is probably the most important. Most ATs fail due to over heating.

An up-pipe, exhaust and tune will get you a very significant incrase in spoolability and response. That alone should be enough to take a sandbagging manual, and all but a full launched manual.

As said.. start with the cooler of course. But a TC will round it out much better if you stay under the 250WHP mark. If you exceed that, it's not an option to avoid the VB upgrade. You'll need to, and at over 300+ start saving for a full race built trans.

Any other questions, don't hesitate to ask.

Here here, good points made. The best 1/4 racers more often than not run an auto. Auto-x, thats where a manual belongs.

lol, good point on traffic driving... I go to work damn early just to miss rush hour traffic.

What does a built 4eat go for? I think I may be heading in that direction pretty soon.
