From the limited info I get from turbonetics it is a stage III p trim, but according to the site it should have a .63 housing. Now I know that their housing differ from the common one however it doesn't say .63 on it. Where the header flange is it says .82 a/r then has the T logo after it. If I read your post correctly they list the .63 housing but it actually is an .82. Now that being said their .82 housing what's that equivalent too, a .96. The housing is fairly wide
What I can't figure out is the the compressor looks very tiny even the housing is quite small, but there is a decent pitch on it though. Why someone would put a very large housing on it with a stock stall converter(old converter). So my question is that if this is their .63 housing(even though it says .82 on it), I assume that they don't make a smaller housing for GN applications, what's the next step. The new housing is $192 and they swap it for free.
I don't know if it's as simple as taking the old housing off and putting the new one on. The other thing I'm worried is losing all that topend power. By going to a smaller housing I will have all the low end power I need, but how much will I lose on the top end.
