99' Subaru Legacy GTB project


Recommended Posts

Hey Guys


Ive got a 1999 Subaru Legacy GTB (ej208), The car is built from 2 different cars with a lower km motor inside. 

I got it for cheap  and it pretty rough, looking at some mods or tips on how to make this car fun but reliable and look the part

First turbo'd vehicle i have owned, and i do not know much about this motor, with all the vacuum and boost lines looks like fun

Ive heard changing the turbos is a good way to make these cars run nice


so far the on the list is:

Scarles Front mount intercooler kit and a GT2 600x280x76 intercooler

Gauges ( Boost, Oil Pressure, AFR)

Ideally some sort of Cold air intake

some nice 18x8 wheels and tyres

Full respray

maybe a body kit, RSK front bumper, or some lips of some sort?

New rear Garnish (As cracked and leaking water)



Things i have done already is 

HKS Turbo timer

Fluids Changed

Uniden immobilizer and alarm

Changed spark plugs ( Not the best to do )

RFRB Grille


 As I've said I'm fairly new to boosted Subaru's, so any advice would be great

Just finished taking mine for a ride after doing the "hose 10" mod, Seems to be a bit more responsive, slightly higher boost 12psi on primary and 15 on secondary. Plus the added bonus of more whoosy noises 😄


Wth the STI Spring and seats, Which version did you get them out of? any trouble fitting seats, like i know modding seat rails needs cert and my car is a long way off going for cert




Cheers 🙂

That'll be next on my list then 😁 after messing around with EVC rod. Thinking about maybe doing a decat on downpipes, just worried about overboosting, EGT's etc (Car has already had main cat ripped out). 



The Z/S downpipes I had were decatted and 2.5"(? maybe 2.25" - larger than stock) didn't notice any boost spikes on my RevD but YMMV
