Setups like this are going to be around 500bhp coupled with a front mount intercooler and a custom fuel system.

The 3.0ltr 2JZ-GTE is very similar to the 2.5ltr IJZ-GTE.

Many of the Supra performance modifications will be suitable for the Soarer, turbo upgrades, front mount intercoolers, fuelling & controls. 

While I do not profess to be a leading authority on tuning the Twin Turbo Soarer during the past few years I have researched lots of options & tried many of them. The Soarer TT is closely related to the Supra Twin Turbo the major difference being that the Supra has Sequentially operated turbo's and the Soarer has Parallel operation. There was/is a popular misconception that the Soarer had Sequential turbo's, I have actually seen magazine articles describing them as such, this myth has caused a lot of arguments and has probably lead to the early demise of many turbo units due to incorrect boost modifications.

Basic Principles:

The Turbo, Exhaust, Inlet, Intercooler, Fuel Supply & ECU are all inextricably linked together to provide power, any change to one of these elements will have an impact on performance and also on the other elements.

More Air In = More Power Out:

The greater the volume of air/fuel mixture you can get in, the greater the power output will be, assuming the engine can burn off this mixture efficiently and be able to expel the waste gasses. Free flowing inlets and big exhausts are used to aid the breathing.

More Boost = More Power:

In principle only, the amount of boost used needs to be carefully controlled & monitored to prevent damage or reliability issues. Over-boosting a turbo engine beyond practical limits can lead to detonation and component failure.
