If you can list some of your mods and what you did to beef up you trany so I didn't boil or spill I won't bother you heehee . I am looking to do it within 6-8 months from now. now is research time.

Default MY99RS-t 10 psi w/4EAT

Currently I'm working with Level 10 sorting out the electronics for the 4EAT. The tranny was built by Level 10 w/ modd' valvebody and billet TQ. It is very important that you step up the line pressure or you will wear out the clutches in the tranny ... especially 3rd gear for some reason.

If you want to talk with Pat Barrett [owner] at Level 10 call him at 973 827 1000

How much would the Level Ten upgrade cost? Raising the line pressure would make for harder shifts correct?

The Auto tranny is actually a LOT stronger than the 5 speed is.. supposedly around 300-400... I heard of a guy with a tricked out sube that was useing nitrous to spool up the turbo while he was on the line... That is what finally killed it too..

Default Nitrous off the line

Yes, having the nitrous engaged as soon as I accelerated off the line is what annihilated my transmission. Running at 5psi for 1.5yrs didn't cause any problems as well as running 5psi with 50-60shots of nitrous engaged after 3000rpms.

I think brake torquing a 2.5RS-T at higher rpms could cause the same problems also since stock for stock RS's have almost 30hp more than my car. Just a thought!

A guy name 'Mark' had an autotranny 2.5RS here years ago but he bought an Audi S4. I'm at work now but if I find his website (if it's still up) when I get home, I'll post here.

Patt Barret did my valve body on my OBS. It shifts nice but it may not be for everyone. Head snapping shifts happen even at moderate acceleration. I have no turbo anymore more and my car is a mid-18 second monster now . Even still, my wife braces herself when I floor the car from the start because it'll throw her back in her seat if she's not careful. I like it! Talk to Pat Barret at Level 10 about the Hydrosystem for details. L8Rs

I think if you run a turbo between 4-6psi of boost, get synthetic transmission oil, and most importantly....a tranny cooler, you will be fine definitely. The 7psi won't be enough. You'll want to get a valve body job before getting that cheap boost controller. The boost bug is nasty. The nitrous bug isn't any better either.

I forgot to mention the most important thing here...and Pat Barret will probably tell you this a 100X over. Heat is the enemy of our auto transmissions. Just as some of the SVX owners. Getting synthetic tranny oil and a tranny cooler (Hayden Type 403 is cheap a cheap good one) helps control the heat, which helps preserve your tranny. Even with the extra hp, breaking parts never happened. It was the heat that destroyed the clutch material and caused bad things to happen.

Hey I'm flattered man but I'm no expert. This is what I'd get though in this order.
  • Valve Body
  • Tranny Cooler
  • Synthetic Transmission Cooler
  • Transmission Temp Gauge *To keep an eye on your temps*

This is all I'd say you would need for up to 7psi. If you plan on going higher, you may as well get the full tranny upgrade from Level 10 or some other shop. Remember, Level 10 is not the only name in town. You'd be surprise at what some of the local guys in your town can do. I found a shop just a few blocks from me that rebuilt my transmission for cheap with stronger parts (so they said). I did my best run(s) with this setup amongst other things and my car is still running good since January. He (Michael Bauer of Benchmark Transmission) said he can perform a valve body and/or torque converter upgrade on any car I bring in and also give it other stronger parts. I'll be going to him for future projects.

Level 10 is a reputable shop that is top notch and is known for their tough autotrannys in import cars like some 10 second street driven Supras. Shop around!

Courtesy of Level 10 website *Note that the Level 10 Hydrosystem is a valve body job of sorts*

First of all, many transmissions have well-known shifting deficiencies - some transmissions have problems when reverse is engaged, other transmissions have a poor 1-2'' shift. Level 10 Hydrosystem™ Recalibration corrects these deficiencies.
Secondly, Level 10 Hydrosystem™ Recalibration optimizes the driveability and improves the shift feel. Transmissions used in heavy-duty applications, such as Recreational Vehicles, Sport Utility Vehicles, vehicles that carry heavy loads, and vehicles that pull heavy trailers will have well controlled shifts that maximize driveability and minimize heat build-up and wear in the transmission and wear-and-tear on the vehicle. Transmissions used in high performance applications, such as street rods and race cars with high horsepower, turbocharged, or supercharged engines, will have firm, positive, tire-blazing shifts that optimize acceleration and minimize heat build-up and wear in the transmission.

ah, it is starting to make sence now wellIwill now look around for guys to rebuild my tranny. I might just go to level10 and have them do it if that makes sence. Also with a 7psi turbo what do you think my hp would look like on a 02rs guys? I am thinking about 180....does that sound right?

180? No, with 7psi you should be running at least 230hp, but probably more. Definately over 200hp.

Nick, I hope I don't sound like an arse but try using the search function. Here's one link: http://www.impreza-rs.com/forums/sho...highlight=dyno

Use the search word 'dyno' under Aftermarket turbo's and titles only. Some useful posts will come up. I recommend lots of Bounty towels for your under-side since uncontrollable bowel movements may result from the charts you'll see.

Way more. My car dynoed with 228hp at the *wheels* at 7psi of boost. probably more like 270-280hp, considering that a 165 hp stock 2.5RS dynos at around 120 at the wheels, give or take.

Tuning has a lot to do with it though. I'd say my car still has another 20-30hp left in it if I were to tune my fuel/ignition maps more aggressively to take advantage of 94 octane gas, without increasing the boost at all.

00RS-T auto (hoping to convert it to manual)

efoo is right, its all about tuning. with an ITC and some great gas you can get easily another 20-30hp on top of the whatever psi you are running.

I would like to ask another (few)question(s) under this topic if I might. I am wondering if any one has a 02rs with a turbo because I want to know if the IC can...well...fit under the hood. Also Doesn't the IC get get cooled also by the hoodscoop in front or is that totally cosmetic?
And finally what turbos are you guys using. I would like to start looking at certain turbos now.
yet again thanks guys for ALL the help. You have gotten me excited and well happy that I did get a auto and I still will be able to make a great car preform even better.
thanks
-Neal

The hood scoop in WRX's is funtional, and in any 98-01 RS-T the hood scoop is funtional also... Unless you can come up with something, I thinks you will need a WRX hood, or a carbon fiber hood with a scoop..

since we are on the subject of RS-T with an auto tranny, how much did some of you guys spend to get it to run 7 psi of boost, and what kind of work may need to be done other than a turbo install. If i am understanding correctly, i can use my stock tranny with 7 psi of boost as long as i have a tranny cooler?? can soem of you guys help me to understand more. The last thing is, where did some of you have or get your turbos made and installed

from what i understand....
stock tranny can be sued if you cool it.
A torque converter upgrade is suggested (levelten.com)
7psi is safe for the car at stock..
Don't hold me to it.. I will get you more info as I collect it.

Goodluck
