The machine shop.





They do a lot of work for Flying Lizard Motorsports. When I was picking up my parts, he was modifying some RSR sway bar arms. Here are some brake hats in process for the Lizards.



The machined case. The sleeves extend about an inch into the case so it had to be opened up for accommodate the 4.0 liter sleeves.




Here’s the cylinder head and case mated together. The machining process was such that it provides a seamless transition from the cylinder housings to the case.




4.0 sleeves are test fitted.




Here you can closely see the finish of the Nikasil coating on the cylinder walls.



While waiting for the machine work to be completed, the coolant pipes were welded. As many of you know, the glued pipe interface has become a well documented Achilles heal of the GT1 engine. The welding isn’t going to win any beauty contests, but is functional.
