Option 1, uprated standard intercooler, known as an SMIC, this is a direct replacement and is a great option as it retains the standard intercooler ducting and our Whifbitz Supra intercooler is rated to 550bhp so is also capable of running a small single turbo conversion too. You have 2 options available, replacement uprated standard mount intercooler and uprated front mount intercooler. Stage 4: If you are using the original intercooler that your car left the factory with then the chances are its had it, caused by corrosion and nearly 20 years of road debris hitting it.
Running this boost you will see a nice healthy 400bhp, this transforms the way the car drives and most of our customers are happy with that power level. We recommend the Greddy range of boost controllers as they are reasonably priced and very easy to use and setup. Stage 3: To maximise what the standard turbos and fuel system can give, you need to run 1.2 bar boost, this is achieved using a boost controller to raise the boost from the baseline wastegate pressure. We offer our tuning kit which comes with all of the parts needed. Fitting these parts normally gives around 380bhp approx. This normally raises the boost level to around 1 bar, at the same time we recommend fitting a Walbro uprated fuel pump to increase the fuel delivery, NGK iridium spark plugs with the correct heat range grading and an HKS FCD to remove the standard fuel cut on the stock ecu. The Jap spec twin turbo cars must run a restrictor ring/plate otherwise the boost levels will be to high resulting in engine melt down. This increases the flow through the exhaust improving power and response too. Stage 2: Next up you need to remove the restrictive catalytic converters, this is known as decatting. Also recommended is a performance air filter, either a K&N air filter element for the standard airbox or a Blitz induction kit. These are available in 3” to 4”, size depending on your power goals, single and twin box depending on how loud you need it, all available in stainless steel or titanium.
Stage 1: The first step is to change the exhaust system, remove the standard restrictive exhaust and let your 2JZ engine breath with an aftermarket exhaust like one of our own very popular Whifbitz Supra exhaust range. Here is what we would recommend as basic tuning guide for your Supra twin turbo 2JZ-GTE: In that time we have built countless big power Supra’s along with our own company demonstrator which currently produces 1336bhp! Here at Whifbitz we have a huge amount of experience on the Supra’s and the 2JZ engines as we have been specialising in them since the year 2000. The turbo version of the engine known as the 2JZ-GTE will take 700bhp reliably in standard form, so with bolt on parts you can have supercar performance. The Toyota Supra JZA80 is one of the most highly tuneable cars on the planet. Toyota Supra tuning is our area of expertise, which we have been doing since the year 2000.
