The heavily modified '84 Turbowagon of Tech Works


Recommended Posts

Here are a few answers to some of the questions that have been posted.

 

-No the header is not equal length, but could be easily accomplished by moving the 180 degree bend primary forward aprox. 3 inches. This header was made with stainless pieces left over from another project we had done. It was a spur of the moment decision brought on by that disgusting piece of bathroom plumbing Subaru call an exhaust manifold. We are considering producing this pipe for a short term due to the recent interest in this item.

-The intercooler is supplied with a good supply of cool air through the RS 2.5 hood scoop. The engine and turbo have a ceramic wool insulated aluminum heat sheild that further isolates the charge-cooler. This has shown Air intake temperatures barely above ambient.

- The turbo charger is a GT 17 Garret ceramic ball bearing center housing unit designed for a Saab 2.0 litre. It is capable of 220hp aprox and has been shown to produce full boost of 16 psi by 2200 rpm with proper exhaust components.

Most of the components on the car are left over from several Saab turbo kits we designed and sold.

Engine management issues such as fuel control and spark management, have yet to be completed as this system will be transplanted into a 1991

NA wagon. The header is designed for the EA82T. It will fit the EA81T but the primaries are too large to encourage proper exhaust gas velocities on the EA81T. If there was sufficient interest, we may consider a similar design with smaller primaries for the EA81T.

Damn, gt17, that is smaller than a T2 housing. You can tell I am new to the classic subaru world. What are you doing as far as fuel management. I know that if you crank that up to 11 psi you are gonna be pretty lean. Do you plan on keeping it at a more resonable level? I have some schematics for a cheap relay setup for an additional injector if you wanted to up the fuel system. Look into water injection too, as it may allow you to run a little more boost without risk of detonation.
