Final Turbo Install






The Wastegate






Well they have finally come in. Here is a picture of the Tial 46mm external waste gate. This unit will bypass about 1.3 bar of exhaust. What this will do for the engine is enable it to run stock boost if I decide I want just stock boost of 7psi. I must say this is an excellent unit and appears that it will live a long and happy life. The Tile, unlike some of the other external waste gates is made of stainless steel on the exhaust side of the unit and aluminum on the actuator side of the unit. I am very impressed with it's construction. Note the large exhaust hole to vent the exhaust away from the turbo exhaust turbine.

The Turbo




Here is my prize. This unit is a special build I have come up with. The compressor is a TO4E housing 60 trim with a 62-1 compressor wheel. This should get me to where I want to go with this car.


Note the exhaust flange on the exhaust turbine housing. This is a Garrett housing with a .70 A/R The inlet to the housing is basically a T4, but with a T3 mounting bolt configuration. The divided inlet will help with the spool of the turbo.


The exhaust side of the turbo is a flange type setup with a V band to secure the down pipe to the exhaust turbine housing. I choose this configuration as it is much easier and simpler to make the modifications to my current down pipe for this turbo. I was also very pleased with the ability to clock the down pipe to make slight adjustments as needed. This configuration is much easier to remove and install then the stock Nissan flange configuration. No more making flanges for the turbo, no more worrying about stripped studs or nuts trying to remove the down pipe for what ever reason I need at the time. All the exhaust parts are stainless steel up to the flange off the turbo now, and easily changed.

Overall I am very pleased with this new setup. I believe it will prove to be an excellent upgrade for my car and get me to that 600Hp that I have always wanted to do with the car. This is going to be a killer setup and so easily installed and removed. I am going to have to do some of my custom work in the exhaust turbine housing area and in the compressor inlet area, but that should not be to much of a problem on a lathe. hehehe, I cant wait to run the car with all of it;s new stuff.
