A couple months ago i finally sold my dirt bike and went back to 4 wheels where i belong. Managed to pick up a 1990 Legacy GT Turbo for $700NZD with its only problem being a massive water-leak.

 

Long story short; fixed the water leak, threw the 4AT away and put a 5speed from a WRX into it. Shes VERY low geared (3200rpm for 100kph) and moves quite swiftly.

 

Plans are to use this car solely for track events and autocross so the interior has been removed and 4point harnesses and sports seats are in the process of being fitted.

 

She weighs in at 1250kgs with a half tank of gas and just passed inspection :banana:

Vitals:

1990 Legacy BC5

1st generation EJ20 motor with quad cams and coil on plug ignition

IHI VF10 turbo (soon to be swapped for a TD05)

4.444final 5 speed AWD transmission with rear LSD

Air to water intercooler

 

Unsure of power figures at the moment but shes getting dyno'd next weekend. Official specs say 200hp @6000rpm and 191lb/ft @3600rpm

 

Ive been keeping a log of my work on her over on the NZ clubsub boards as they know JDM quite well. Just couldnt resist posting the customary "yay i got a new car" thread.

 

Cheers

Just a couple little updates that might interest you guys.

 

Im getting approximately 500kms on 40liters of gas = 29mpg

Thats almost all highway driving but still a nice number - im happy with it.

 

My H6 GT30 is getting 26mpg doing mixed highway and town driving.....but it has air-con, leather, a heater, premium stereo and carpet so i'd still rather drive it to work over the track car.

 

At a dyno day organised by a fellow ClubSub/subtalk member, the turbo made this run:

This run from a stock EJ20T with the air to water intercooler, only mod is a cat-less downpipe.

 

My boost pressure is far too low at the moment so my next addition to the car will be a boost tap so i can dial it into 12psi where it should be.

 

Edit: Just wanted to note this is just the first run. I wanted to get a base line before i start playing with things. The next run im aiming to break 150kw at the wheels. After that ill be hitting the track to get my driving up to scratch
