BMW E36 M3 Intercooled Turbocharger System

After the fourth iteration of forced induction BMW#146;s, with almost every conceivable blower type, we simply cannot justify, either technically or functionally, any other mechanism than the turbo. We have unhesitatingly set our sights on building the best #147;spare no expense#148; system that twenty-five years of experience permits. It is quite evident that the #147;best#148; had to have the turbo.

At the outset, we had no specific agenda regarding blower types, eventhough we have been producing turbocharger systems for various BMWs over the last 25 years. The perception after one trip around the block in an M3 with a centrifugal supercharger (CS), clearly showed that it was not an acceptable machine. This system was built by the current #147;top dog,#148; and is representative of the best offered today.

After months of evaluation of the fixed displacement blower, we concluded this approach offered the best performance available under 2000 rpm, but real power was going to be very illusive. 2000 rpm is not the performance range that fast motoring is all about. When the complexity and cost required of the fixed displacement blower installation was summed up, the low rpm advantage was not considered worth the trouble and expense. Then came the turbo.

The whole spectrum of performance of the turbo just came alive and easily proved vastly superior to our experience with the CS. Except for boost below the 2000 mark, the turbo performance so badly eclipsed the fixed displacement blower that our path to the intended performance was clearly spelled out.

We had many objectives in mind when designing this system. Simplicity and serviceability were of urgent priority, but the two greatest objectives were; first, to weed out all the #147;fussy#148; little problems that have thus far kept forced induction systems for the BMW from being either acceptable or successful. Second, to build a system technically and functionally correct.

The simplicity, elegance and component quality of M3 turbo solve all these problems and create many happy owners. The performance of the turbo will create even more incredulous owners. The long term durability and fuss free operation of the turbo will produce a whole new cadre of firm believers.

Major Component Description

We manufacture all of the components in our systems completely in-house, with the exception of the electronics and the turbocharger. Hope the following data answers a few questions.


Exhaust manifold:

We designed and patterned this manifold completely from scratch. Styled after the Offenhauser Indy car manifolds, this ductile iron casting is extremely strong, yet not overweight. The decision to use a casting and ductile iron as the material is prompted by the desire to have a high-quality and high-durability piece.

The design is slightly conical from the port to the turbine entry and thermal expansion is carefully controlled such that thermal warping is eliminated and straight line expansion assured. This manifold will flow well up to rates equivalent to 600+ bhp. The T4 turbine flange is machined precisely to eliminate the usual gasket. The manifold comes to you with a proper thermal coating.

No paint. Stainless steel fasteners are provided to hold things together.


The Tial unit is a CNC billet aluminum top and stainless base. It’s a race quality item with the highest temperature diaphragms available. We have integrated the gate into the system in a very interesting manner.

We utilized a layout similar to the Toyota IMSA GTP racers of a few years back (arguably the most successful turbo endurance racing effort since the 917). This gate configured to be compatible with modern remote controllers. A Cartech boost gauge and Greddy Profec-B electronic boost controller are also included in the system.
