Mazda built a homologation special for WRC before Ford took majority control of Mazda in the early 90s and killed the program while competing with the Escort Cosworth. The 323 GTR came with a BPT engine with a huge 300+ hp turbo on it stock and some neat internals such as forged rods, pistons with Iron ring lands and internal oil passages for cooling, sodium filled exhaust valves and such. A couple thousand were sold worldwide none in the US. stock power rating was 210 hp but it would handle the boost being turned up quite easily the turbo is bigger than my GT3071R. All wheel drive 2600 lb car.

Would you still recommend that for a KAAZ diff? I just put in poly diff bushings so now I can hear all of the awful noises that the KAAZ is making and I feel like it's a bit excessive so I figure I'll try to quiet the diff down before going back to rubber bushings. Plus the diff came installed on the car so I have no idea how old or what the fluid in there is.

Where/what conditions is the giken gaining that much ground over the Torsen? In GRM's test a few months ago they actually lost time ... but I don't think GRM got as much out of the diff as the diff had to give. A number of their tech articles/comparisons lately have had some flaws.
