In 1986 came the first Supra model and in 1992 came the first version of the Supra MK4 - and ever since then the car and engine have been used for high-performance racing and tuning. It has been used a lot as the standard turbocharged 2JZ-GTE engine without changes could make an incredible amount of power.

In Japan, the 2JZ-GTE engine can be found in the Toyota Aristo made from 1991 to 2002. The 2JZ-GTE engine was updated in 1997, with variable intake cam - VVT-I

Toyota's 2JZ-GE suction motor is based on the same engine block and almost identical, but with higher compression. Toyota's 1JZ-GTE is a 2.5L version of the well-known cast iron block which was later made with variable intake cam and single turbo.

The 2JZ engine is built as Nissan's RB series - 6 cylinders in line with good balance, 7 main bearings, which allow for high revs.

A doubling of power - Up to 700 hp.

700 hp. is possible on a standard motor without disassembling it. It is required that the engine is in proper condition, ie. it should preferably be renovated with new bearings, engine oil, piston rings, etc. A larger turbocharger and exhaust manifold should be used.

With a larger turbocharger, you should expect to have full charge pressure at approx. 3900 RPM. If you want charging pressure before, you must have a turbocharger with ticket wheel and ceramic bearings, here you can get down to approx. 3600 RPM.

Performance T4 manifold - Cast iron manifold with 38mm. Wastegate

Performance T4 manifold - Cast iron manifold with 44mm. V-band Wastegate

38mm. & 44mm. External wastegate - Fits directly on the manifold above

Oil hose kit - Access and return to the turbocharger

Water connection - Kit for water cooling of turbochargers

Turbokit for 2JZ - Here is everything you need for mounting larger turbochargers

Intake - High-performance intake

The original intake manifold can be used for many hp. and seems sensible. However, we have a Performance intake manifold which gives extra power and looks much more healing - Very much when you start tuning the engine. It is made for Bosch / Siemens nozzles with 13.5 mm. O-rings. We can recommend eg 668cc or 875cc. nozzles that can carry up to 600 & amp; 800 hp. - Large højohms nozzles can give a more unstable idle, if you run a slightly fatter mixture at idle, it does not give any problem.

2JZ performance intake - Really nice intake manifold that has a super good flow.

668cc. nozzles - Nozzles that carry up to approx. 550-600 hp. - Depending on the mixing ratio

875cc. nozzles - Nozzles that carry up to approx. 750-800 hp. Everything depends on the mixing ratio

EV1 connector - Connector for mounting the above nozzles, the connectors are replaced very easily if you have a pair of pliers that can squeeze the pins.

Cooling - Large intercooler and aluminum cooler

Cooling of the radiator system and charge air are both very important factors when the car is increased in power by eg 100% - We have, for example, an aluminum radiator with a thick element and good cooling. The intercooler system also needs to be heavily upgraded, here we would recommend min. and 600 * 300 * 76mm. to 600hp. The element that is 100mm. thick to 800hp. - You can find it on the link below.

Alu cooler for Supra - Large aluminum cooler for Toyota supra, thick and efficient radiator

Intercooler - Universal intercooler if you want to install intercooler and make piping yourself

Aluminum pipes for pipe system - Aluminum pipes are lighter than stainless steel pipes and can thus be an advantage to use due to the weight

Silicone hoses - For building an intercooler system, choose between Black, blue and red.

Complete intercooler system - If we do not have a plug and play for your particular model, we will be happy to get it home.

Exhaust - Upgrade exhaust

When you need to tune your 2JZ engine up, more air needs to be in the engine and therefore of course more out. It is recommended to mount a 3.5 "system to get optimal power out of the engine. We build many exhaust systems for Mercedes AMG, Porsche and other great brands - therefore we can also offer a specially made exhaust system for your car!

Build your own exhaust - We have all kinds of parts for racing exhaust if you want to build your own

Stainless pipes - Exhaust pipes and bends

Gas Station - Upgrade
