Background:
I started this project over a year ago. Found a neglected 88 Turbo 5 speed that had been sitting for 2 years listed for $1000. I check out the car, there's a R154, ct26 with very little shaft play, a fairly clean underbody (i think it's been on stock suspension it's whole like), a clear case of BHG, and what I later confirmed to be a melted/clogged cat in the downpipe.
$800 later i owned my third supra, first turbo one. A week later under the cover of a cold night i drive the supra home. only in the last couple of miles did the temp start to creep up. A leaking hose was to blame but it didn't matter the head was coming off (I'll add in photos of this soon).
This was to be a cheap 24 hours of lemons car but after taking the head off it was discovered there was fingernail hanging groove in cylinder 4, coolant had sat on the piston ring and ate it's way into the block. This is where it snowballed into a different project, .040 over CP pistons, ARP head studs and rod bolts, a MHG, and 1:8.9 compression later it's become another beast.
I wanted to start my build thread at the fun part:
Compressor Wheel OD (exducer): 71mm
Compressor Wheel Inducer: 57mm
Max Flow Rate: 60 lb/min
Turbine type: Low Inertia Gamma-Ti Turbine Wheel
Turbine Wheel OD: 63mm
0.80 A/R T4 Twin Scroll (Internal WG)
After the months of waiting for machine work, getting parts, breaking parts, re-installing parts correctly, waiting on funds, etc...
Right now have a working car with 4 days worth of one day passes in it. 99 miles on the new engine, My machine work was done well enough that i broke this in after only a couple miles, the first 40 I had some oil in my intake pipe but after cleaning it out and going another 60 it's still clean and from the feel of the motor now I'd say the rings are on there way to being well seated.
Current parts:
Full silicone kit (china)
Working stock downpipe
large aluminium radiator with electric fans (that hardly ever come on)
a poorly made crush bent downpipe back exhaust with fat can and stock cat welded in.
lot of OEM parts
near future:
A Greddy SP exhaust when i got 3"
PLX wideband
Apexi boost controller
RC550s lexmaf and a reflashed ECU
farther future:
EFR turbo
Intercooler and piping
possibly 680cc injectors
wrap up: I'll be adding more photos as i collect them and make a few prequel posts. For now the car's about to try out smog and i plan to keep it a responsive daily driverable car.
