Nice Mike,you can run a powerglide in a lite car,but agree it doesn't seem rite in a SkylineMy old 1992 Mustang coupe with a 600ci. alumumin big block with 2 stages of Nitrous had a powerglide. It's probably the most durable transmission in drag racing. I understand why they did it, but it just don't seem right in a skyline.
I have written a lot about Nissan Skyline GT-R gearboxes. I have used a lot of combos, gearsets, drivers, etc over the last 12 years. You can make things survive better, or longer, but it depends on the driver and the car.King a hallinger transmission would be better for a street car but it's $13,000 or more.
