I own a 94 tt auto and i am currently at bpu. I am now looking to take the next step performance wise. Without going single, which i can not afford at the moment, what would be the next best step for power increase? I obv have a budget but i have a fair enough amount of room money wise. I would just like some advice for what else i can do beyond my bpu setup. My mods so far are: Intake, downpipe, exhaust, fmic, fcd, bc, wheels, lowering springs and a few other little mods here and there. I am also currently set at 18lb of boost. Any advice would be appreciated. Thanks!

gut the trunk then lol
if you can rebuild Turbos then you can put a nice T3 60mm wheel in the stock twins. or buy the GT28rs but that's almost single turbo money
i'd defiantly go ProEFI on E85

I thought about a torque converter but how would it be as a daily driver?
Fine your stall will not be big enough to affect you, just get a transmission cooler with it. (stall will build heat)

next best thing for you.


map ecu 2 for a tune + meth injection + a twins rebuild...... map ecu 2 will run i think 500 about, a meth kit will run about 500, and a twins rebuild... well.. depends on where you go. you could just do the first two and net almost 420hp depending on how much you want to push the twins, but run them ragged and you will risk destroying them.. they don't run too efficient after 18psi... youll have gains, but the gains are short lived on turbo life when you max them out completely.

also a stall converter might be fun depending on what kind of racing you like.

I actaully thought about going with the map and maybe an ems. Would the ems be a waste with the stock twins or no? Also would i get much out of a meth kit with stock twins also? Deff was thinking about getting the turbos rebuilt or even buying newer ones. I'm around 97k miles and im sure mine have lot of play.

couldnt tell you about the ems.

but the meth kit would be basically insurance to make sure you aren't knocking when pushing the twins past 18psi.

you can run higher psi without meth and without a map ecu, but you'd have to run 100+ octane, and reset the ecu in order to get any benefits. once the ecu detects knock, it will retard the timing and you will lose the power gained from the increased pressure.

people have doing the ecu reset trick for a while.

youll get more power out of a good tune as well as something to make sure you won't knock like a little meth injection.

plus it will be in place for later when you get bored. seen a couple supras put down more than 700 on meth for an everday street use on nice spooling turbos.

Not a huge engine or tuning guy and still learning, but what exactly do u have to do to reset the ecu? Is that something I should look into or is it a simple step by step explanation? Also the meth injec kit would be nice to have for now and even in the future when i do decide to go single

Remove the negative battery terminal for a while, and you should be good to go ;)

argh no, lol, youll lose all your stations and shit too.

just open the fuse box in the engine bay and take out the efi fuse.

leave it out for a minute so all the power drains from the ecu, put it back in and go.
News to me. I was actually told on this site (many years ago, though) pulling the neg. terminal was sufficient.

I'm not doubting you. I'm actually curious what you mean by losing all my 'stations and shit'? What shit? (Radio in my car is always off, so no worries there)

lol well. if you do listen to your radio, you'll lose all presets and settings by pulling the cable unless your headunit has an internal power source, which most don't unless they are real high end.

plus, no tools needed to pull the efi fuse out. been doing it for years.

i know that my turbo timer needs to be reset to the settings i had it at (lenght of time and such) when i pull the neg cable or take the battery out. but most electronics should hold their settings just fine.... you never know though. just better toleave power to the car and pull the fuse.


heres a post from 07 talking about it

Cool, thanks for the info.

I guess it's 6's for me. My car is in storage most the time, and has the battery pulled anyway. The negative terminal pops off with a little force, no tools required. However, my turbo timer does reset to 0. If I drove it more that would bother me. But now I see the advantage for 'regular' owners (that drive their car more). Fuse it is! I retract my previous statement, OP. :)
