Evolution MotorSports Project Porsche 993 Twin Turbo 650+ HP TiAL Turbos - EVOMSit - Gemballa EVOMS

We have not built many 993TT's in the recent years, however at one point, all we built were 993's. We took on this project when our customer brought us his car after he over rev'd it and bent the valves. The car / engine was originally built by Gemballa and was suppose to have some very "trick" internal engine upgrades including a 3.8L. We removed the engine and disassembled it to find that the engine was 100% stock. Chances are, the previous owner of the car who had the work done by Gemballa sold our customer the idea that this work had been done when it really was stock. That was a few years back and now our customer wanted to move forward with a "more complete" engine build.

We completely disassembled the engine down to the crank. We installed / performed the following upgrades internally:
Carrillo Connecting rods
All new bearings
Balanced the rotating assembly
Solid rocker arm conversion
New intake and exhaust valves
Fresh heads and valve job
New head studs

After the core engine was built to adequate standards, we knew that we could add some more power without running into issues with the strength of the engine. We added / performed the following upgrades:
TiAL Alpha GT28 turbos
60 lb Motorsport fuel injectors
Gemballa catalysts (previously installed)
EVOMS header modification (increases the header turbo discharge flange diameter)
Larger MAF housing
40% larger intercooler (previously installed)
Gemballa Mufflers (previously installed)
EVOMS Billet Diverter Valves
1.0 Bar wastegate springs
EVC boost controller
EVOMSit ECU calibration

@MkIIIGTi16v Hate to break it to you, but that is not the turbos. It's the dyno.
