Most turbos for sale don't appear to be available with a smaller A/R for an automatic. Is this because so few autos were made, or has the gutted precat or downpipe made spool-up less of an issue for automatics? I see that you can get Sport 500s with an auto A/R, but not a GT525. Also looks like from the Z Registry there were only 3,765 TT autos sold in the US. I wonder if the GT525 or the Sport 530 work well with an automatic? Or should I just go with the 900 hp turbos from SZ. lol
