Calibra Turbo 4x4 Resurrection #4 - The C20LET TopHat comparison guide

Part 4 of resurrecting my Calibra Turbo 4x4 After 8 years. I find 3 different TopHats in the boot, a rare enlarged IRMSCHER replacement, a very rare GM "Fat" unit, and the standard OEM Tophat (GM 90423021). I decided to carry out a comparison and show viewers the different types that were available during the producation.
I purchased the enlarged Irmscher Tophat so long ago that I forgot I had it, I recall it did not fit as the OEM boost pipes were too small. I was searching for the enlarged OEM boost pipe to fit the IRMSCHER setup, however, I was not sucessful finding such. I still can not fathom why the german designers used an heavily restrictive intake system, or perhaps this engine was designed purely for Low-End Torque and not power and hence the engine name LET?
This footage was filmed straight after the horrific encounter with Jabba the Hutt, I still felt vulnerable after that incident, there was two of them too, it took me some time to shake it off. Luckily the discovery of the C20LET Tophats eradicated the itchy feeling.
