thanks guys, ray, what your talking about would require one custom reverse rotation turbo, only way for it to be mirror image is for it to be completely opposite requiring reverse rotation. there is no option for that really with these turbo's I'm using, a custom one would cost a fortune & is not common at all so they have to be, like almost any other twin turbo setup, twin identical turbo's, no practical choice of anything different really... tial doesn't even make reverse housings far as I know & the only reverse custom turbo setup I've seen is starting in the 7k range & still not an ideal turbo for my setup really anyway, so no real choice there...
