Celica GT4 ST185 300hp

Heres my modified 1990 Celica GT4 ST185 300hp on 11.5psi. Haltech elite 1500 controlling turbo and ignition (Coil on plug), fuelling. Motor is from a ST205 GT4 with aftermarket forged pistons.

GT2860RS (currently waiting on a replacement after bearing failure)

When I bought the car it had a lot of gremlins and I decided to bite the bullet and have the loom pulled out and a Haltech one professionally installed.

Work I’ve done:

Fixed a bunch of electrical problems.

Installed dual thermo fan controller and temp sensor

Fuel pump controller

Properly fused rear battery compartment.

Car had overheating issues which I was able to fix by sealing around the stock radiator and installing an under tray between fmic and rad and removing larger intercooler.

Installed a PWR oil cooler and pressure and temp sensorz.

Fibre glassed a reverse scoop and intake into a bonnet and made a custom air box.

Removed 40kg FMIC in favour of a smaller mishi z line.
