FTO GS 4G93 turbo build
Posted: Mon May 23, 2016 11:07 pm
As some of you might know from faceballs and my annoying questions, this is an ongoing turbo project.
I'm a long time lurker here, and this is the first one that was worthy of posting about.
Car is a '95 FTO GS, originally with a 4 speed auto box, imported from Japan in 2004. Was around 58k then, now is 133k.
Came with 17 inch Advan AVS Model 5 rims, and a stainless steel backbox. Otherwise fully stock. 1 lady owner (not kidding, there was a kid seat in the back with some snacks on the floor).
Being a poor student, I've added some polibushes, strut bar, and a subwoofer.
Years passed, had a family, boring diesel estate, but the FTO stayed and I decided to do what I always wanted - turbo it.
Brake disks needed change, so I upgraded from single to twin pot fronts. Got a bigger master cylinder as well - 15/16, but didn't like it, so now it's running an Evo 4 one with 1'.
Lowered the car with Apex springs, and I'm surprised how well it handles now - stiffer and lower, but still damps good.
Next thing was the manual conversion, mainly because the 4 speed auto gears were not enough - 1st and 2nd had a huge gap, and 3rd was already close to 1:1 ratio.
Polibushed the engine/gearbox support beam to stiffen it up a bit for the incoming turbo.
It starts like this:
Oil pan out for oil drain:
Impreza WRX TD04 to go in, since it's should suffice for 1.8l engine that wants low-mid rpm boost:
That later was found to be very hard to place where we wanted, so it was ditched in favour of the bigger better one - TD05 from an Evo IV.
Intercooler in and painted black:
Intercooler piping done:
Turbo manifold version 1 - design based on ToxicFab's Evo VIII manifold:
Unfortunately, this would come too close to the hood/bonnet, and even with insulation would fry the paint, so it was dropped.
Shorter one was made:
Painted black and insulated:
