Toyota 7MGT Upgrades
In our opinion the Toyota 7MGT engine is the absolute best powerplant available. You can make huge amounts of HP reliably if not cheaply. Low 12. s and high11. s from a early body style Supra is very common and not very hard to do. The down side to this engine is there is very little bolt on equipment that makes much difference. You need to jump right in and do the big stuff. Sure, you can do and air filter, exhaust, EVC, Etc. but the real power comes from serious Turbo and fuel system upgrades. Along with these mods the internal engine pieces must also be upgraded to withstand the extra heat and stress.
Our standard street buildup is about 500 HP on pump gas and 600+ on race fuel. Internal Engine work is fairly straightforward and all pieces are readily available. The Turbo and fuel system is a bit more complex. The stock management system even with an AIC cannot support much more than
425 -450hp because of the Air flow meter restriction. We use aftermarket Speed Density Metering management such as the Electromotive TEC-II, the HALTECH F9A, or the HALTECH E6
The stock ignition system and timing curve is also very good for most street applications once you have control of the fuel and eliminate the air flow meter. To keep the stock ignition and eliminate the fuel only you would use the HALTECH F9A system.

Fuel System Upgrades:
Depending on what kind of HP you are trying to make and what you want to spend you have 3 viable approaches to getting fuel into your 7MGT. Using a VPC or
F-CON is not the answer.
Stage-1 Fuel System Upgrade: $425.00
This is for those of you that are doing mild street upgrades and just need a bit more fuel.
Bosch Racing Fuel Pump
Adjustable Rising Rate Fuel Regulator
Stage-2 Fuel System Upgrades:
For up to 450 HP while retaining the stock fuel management system.
Option-1 $965.00
Bosch Racing Fuel Pump
550cc Fuel Injector Upgrade
Adjustable Rising Rate Fuel Regulator
More fuel all the time. Definitely affects fuel economy and everyday driveability. Also makes it pretty much impossible to pass smog. Easy install with not much to adjust but the regulator.
Option-2 $1095.00
Bosch Racing Fuel Pump
2 Injector AIC System with controller and (2) 550cc fuel injectors.
Includes new over the valve cover pipe with the injector bosses built in.
This is a great way to do it if you want to keep the car running just like stock except when you are at high boost levels and really need the fuel. Will also pass Smog inspection. Controller is adjustable for injection starting point and
duration.
Stage-3 Fuel system upgrades:
Programmable management system upgrades for all out 500+ HP systems.
These systems require using a laptop computer to set the fuel and/or ignition curves. Both systems are complete with software, sensors, tuning manual and baseline programs. This is for those of you that want to get the most out of your 7MGT and retain good driveability. There are 2 methods. The first is to scrap the fuel and ignition system completely and use a stand alone computer to control all aspects of the engines operation( TEC-II or HALTECH E6 ). The second is to retain the stock Ignition system and curve and just control the fuel (HALTECH F9A). Both have their merits. It really depends on the gas you will be running and your how much control you want. A very heavily modified street engine running pump gas will really require the ignition control of a complete stand alone system to keep detonation under control under high boost low octane situations.

It is extremely critical that you know the attention to detail and special machinery required to deck the gasket surfaces down to the RA needed for the HG you choose
