i guess this is more general than STi related, but not really cuz thats the car im going to do it to if its worthwhile, but yeh... i guess im a n00b as far as this goes, but what does a turbo timer do? the same with a turbo back exhaust.

also do either of these harm/limit you in any other ways? can u still pass emissions with the turboback exhaust?

I can help you with the turbo timer question. All a turbo timer does is cool down the turbo by keeping your engine running after you turn off the engine. You can still lock all your doors, set alarm etc... It pretty much prolongs the life of your turbo especially if you were running it hard. Not 100% sure what a turbo back exhaust does other the feed some of the exhaust gases back to the turbo. Not sure why it's better than regular or cat-back. But turbo timer is a cheap way of prolonging your turbo.

Turbo back exhaust I think includes downpipe.

This is how I got it figured out. A turbo back exhaust consists of new exhaust pieces (usually of a larger diameter) from the turbo all the way to the muffler. Cat back exhausts are new pieces from the catalytic converter to the muffler.

Just to let you know, A turbo timer cannot be fitted to the current 2002 model STI that comes standard with the keypad security system. This might only pertain to Australia but worth noting. Apparently even Subaru Australia have looked into it but have also said it is not possible. Guess you just have to arrive at your destination early and sit in the car for a few minutes before turning it off.

Hmmmm , I wonder if it is like that in the other country's STi models...anyone know?

Not that I'm a circuits expert, or that I even want a turbo timer, but it just seems like a question of electronics to get around that problem.

I think there is a modification that you have to do on the current US spec WRX to get the turbo timer to work with the factory alarm. I don't know if this will work on the STi or not. Here is some text and a link:

11) If you have the optional security upgrade from Subaru, you must now modify your car so that your security system will arm while running on the timer.

12) Above the fuse panel, there is a black Keyless entry module. Remove this - 1 10mm bolt.

13) Find the dark green w/ black trace wire and cut it. Tape both ends and bolt the keyless entry module back where it came from.

14) On the security system module (located on the drivers side of the parking brake) find the gray wire and cut that, taping both ends.

15) You are all set. Put everything back together and have fun
