Toyota RA63 2JZ-GTE
The 1985 Celica ST was the simplest of
the last generation RWD Celicas. The 1997 2JZGTE Twin Turbo (Supra) engine
was the most powerful engine Toyota ever imported. Fortunately the (even
older) 1979 Supra rear axle bolts right in. So what we have here is a project
that spans 1979 to 1997. We had the best pieces to do an ultimate project. The
Celica ST is bare-bones and had solid axles, that was replaced with the heavier
7.5” Supra differential (needed to survive the mega horsepower planned from the
Supra Twin-Turbo engine). The engine was modified with Toysport forged pistons, HKS metal head gasket, ARP bolts, and the Traction Control bypassed. A massive
Toyo Intercooler (XXXXX) the biggest intercooler we could get from Japan, fit
behind the modified front bumper/grille. The ECU was modified to Toysport
specs. A Toysport aluminum flywheel with twin-discs connect the 6 speed
transmission. Unlike the other 7MGTE Celica convertions we had done before, the
firewall had to be modified, to better position the weight bias. (On the
7MGTE’s we maintained the original W-series transmission location.) Fiberglass
Group B fenders (original Toyota Homologation items) were the only non-original
body panel. The hood was lifted 2” at the back to help engine bay ventilation.
The 3 stage Supra Twin Turbo fuel pump was installed in the tank. Suspension is
with TRD Springs and Tokico Pro-Drag shocks. Now if HKS sends us their TWIN
TURBO upgrade………hint…hint…hint…
