Manual Boost Controller
Maximum boost pressure is controlled by a pneumatic waste gate on the Turbo 4.9. The factory set up allows for a slow and smooth ramp up of boost pressure. Although it is a seamless increase in power, it does take time to get up to that maximum psi. The factory max boost pressure is supposed to be 9 psi. Some have found their cars max boost pressure to be as low as 6-7 psi.
Our manual boost controller delays the pneumatic actuation of the waste gate until maximum boost pressure is reached. This allows the turbo to “spool up” at a quicker rate. It also allows you to increase your boost pressure above the stock setting. It does not allow you to lower it below the stock setting. You can use this manual boost controller to increase it to the 9 psi (or more with supporting modifications) while also taking advantage of a faster spool up time.

Water-Alcohol Injection
Water injection has been around since WWII. It is a great way to suppress detonation in the internal combustion engine. It especially works great on forced induction engines that can experience high cylinder temperatures. Since the Turbo 4.9 is a “draw through” turbo, it makes it impossible to intercool the boost pressure before it enters the engine. But injecting water or a water/alcohol solution can be used to “chemically” intercool the air and help suppress detonation.
Our water injection kit is a low pressure design. It introduces a mist of water and alcohol prior to the turbo compressor. Since compressing the air in the turbo adds heat, the water vapor helps lower those temperatures through evaporation. The alcohol acts as additional fuel. This allows for higher boost pressures, without experiencing detonation, for more performance.
The nozzle is mounted inside the air cleaner base. It is almost completely hidden from view when installed. It is controlled by an adjustable pressure switch that is included with the kit. You can use distilled water or a water/methanol solution like basic, blue window washer fluid. It is not recommended for straight methanol use.
Our kit comes complete with reservoir, pump, nozzle, check valves, adjustable pressure switch, fuse and indicator lamp.
It is not recommended to use this kit if you are experiencing detonation issues at stock boost levels with premium fuel. Other problems may exist and should be addressed before installing this kit.

Performance Head Gaskets
The factory style head gaskets for the 301 had many of the coolant passages blocked off between the cylinder head and block. I assume this was done for emissions and fuel economy purposes as a hotter combustion chamber allows for more burning of emission gasses and a leaner fuel mixture.
This additional heat does not work well in a turbo application. Especially one with out intercooling capabilities.
Unfortunately at this time, it looks like Fel Pro is not offering the 301 head gasket anymore. Not sure if and when it will be available again.
In the mean time, we designed our own custom head gasket to be produced. It features additional coolant holes that will keep the combustion chambers a little cooler to help avoid detonation. Our gaskets have been dyno tested up to 14 psi of boost on a stock 301.

Turbo Shorty Header System
Shorty header system for the Turbo 4.9 is now available. This is the system that was tested on the dyno and provided a 25 lb/ft increase in torque over the stock manifold system.
The kit includes the following:
- Ceramic coated shorty headers modified to fit the Turbo 4.9
- Mandrel bent aluminized steel "merge pipe" and "up pipe"
- High quality mini starter
- Copper gaskets
This system works with your stock turbo and will clear stock air conditioning components.
Professional installation recommended. Welding required.

Turbo Air Induction
The key to improving the performance of the Turbo 4.9 is to have as cool of air coming in as possible. Since the turbo cars came equipped with a hood scoop, why not make it functional?
TTA Performance has designed such a system. This kit is designed to look like a factory installation and does not require any modification to the hood or any factory components. It can easily be removed and the air cleaner system be brought back to original. No welding. No drilling or cutting. The system even uses your factory air cleaner base.
Note: It is recommended that the air intake hose from the fender still be used in conjunction with the air induction.
Features include:
- Aluminum hood pan (slip fit design, no drilling required).
- New, 14ga. steel, replacement LED boost light panel with air intake holes.
- Small air cleaner lid.
- Air cleaner seal.
- Boost light pressure switches. (TTA-010L)
- Boost light on/off switch. (TTA-010L)
Air Induction w/ retrofit light kit - $475.00 (+ shipping) TTA-010L
Air Induction w/ light panel only - $450.00 (+ shipping) TTA-010P
Air Induction w/o lights - $350.00 (+ shipping) TTA-010
