New beginning...

[Littlestan]

Hello all!

I just recently bought a 1990 TT Supra wide-body aerotop (Targa top) with

the 1G-GTEU 2.o liter engine. It's a 5 speed manual, has 51,000 kms (about

32,000 miles), and is right-hand drive. Other than the exhaust being upped to 3"

from the cat back, it's pretty much stock.

My big question is; what should I be doing to this thing? I've done a fair

amount of research lately, so I have a general idea but this is my first jump

into the import world and I want to get any tips or hints straight from the

horses mouth. (That's be you guys... ^^) I'm a domestic-only gearhead

convert!! Unfortunately, that also means I know next to nothing about

tuning imports w/turbochargers...

ANY and ALL information will be greatly appreciated guys/gals. Even the

smallest detail such as the upgrade of a downpipe or type of blowoff valve to

buy would help muchly.

Thanks for having such an awesome forum!

P.S. Don't be afraid to P.M. or email me with information either; I want to get

every detail! ^^

1g's can make power but due to displacement just not as easy

i would start with upgrading the downpipe... i think 3" is a little too big for a 2L
maybe 2.5" from turbos back
oh and of course before exhaust.... have you got an air filter on there yet? pod filter...
cold air = more power... so you could build a cold air box and get some ducting pipe from the front bumper to the intake

a huge restriction i believe is the intake piping to the turbos... if those were remade i'm sure there would be a big flow difference

careful of overboosting those turbos also.. they're only ceramic and like dying hehe
since you have a 1990 i would assume this is a generation 3 ecu which is either a 9psi or 11psi model... i would work on things around the engine first

so intake, exhaust.... cold air...

upgrade the intercooler & intercooler pipes (custom jobby tho... not much aftermarket support for the 1g)

that's bout all i can think of right now


p.s. ur lucky you got a 1990 1g.. if you had gotten an 89 it would have been narrowbody lol
