Re: Mark's 1G Winter Projects

It’s been awhile since my last update. I dropped my block off to MAP to be machined for the new 2.2L HD pistons and one thing led to another and MAP completed the entire long block for me! Alex did a great job measuring everything on the motor. I can’t say enough how happy I am with the precision measurement, over all quality and focus on details that Alex, Eric and the other MAP members have. I don’t trust too many people or shops, as I do everything that I can myself, but I can say with confidence that MAP’s engine program is world class.

The engine is an:
• Eagle 94mm 6-bolt crank
• 9.75:1 Wiesco HD2 pistons
• 1/2” head studs
• Ύ filled block
• R&R 153mm aluminum rods
• Stage 5 MAP cylinder head, with Inconel exhaust valves and the deck surface has been stinted.
• No O-rings, Felpro Permatorque gasket
• GSC S3 cams
• Kiggley HLA & 12 tooth trigger crank sensor
• 200W heater in the oil pan with an oil temperature sensor.

The motor is in the car now and all ready to be started.



This weekend I finished up the fabrication on the 3000Gt rearend. It’s huge compared to the factory 1G unit. My Pro Stage 5 axles will be custom machined for the new rear. The last rear end only lasted 5 passes. I kept breaking the spider gears and I didn’t want to weld the diff and have ring and pinion failures.


The car is almost down 100lbs too!

I want to break my cage certification. Sub 8.50’s here I come!!!!
