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.
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.
Stainless high-performance manifold - Stainless turbo manifold for 2JZ
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 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
If you need to upgrade your petrol pump or install a Surge tank, we have everything you need. A new alu fuel tank/fuel cell can also be a solution if you have to race. We are happy to help if you just need the pieces or have designed and installed the entire system.
Upgrade petrol pump - Here you will find several different petrol pumps for internal and external installation
Surge tank - If you need external petrol pumps mounted in a surge tank, we have many good solutions
Fuel cell - Fuel tanks for race
AN-fitting - Everything in AN-fittings for reinforced hoses, petrol pumps, petrol filters etc etc.
Fuel systems - Everything for installing a new upgrade petrol plant
With the Plug and play box from the ECU master, it is very easy to mount a new programmable motor control on your car. The price for the PNP box is very low, need an ECU master control along with the PNP box - But still a very low price.
PNP til 2JZ - Plug and play system fra ECU Master
Ecu master - Controls and various accessories
Boost controller - We have manual, electronic boost pressure valves that can also be connected eg ECU master
700+ or if you want to be sure that the engine runs a lot of km. after upgrade turbo etc. you can advantageously switch to JE pistons, H-profile connecting rods, strong ACL bearings, ARP bolts and other top gasket.
