And the KA is free
And after helping pulling and tearing down the vg30dett in my friends z32 to find a beautifully damaged piston (its unlike anything ive ever seen its.... wonderfully horrible) last night and tonight.... You dont want one. Its hellish in a Z32 alone, thats all you should really look at. This is from a rather stripped vg, in a top 3rd fastest stock turbo z32, in the US..
Then again if you are loaded, pay other people to do you stuff, and dont mind long long periods of downtime go for it.. But even with ballance tubes the whole dual stage junk doesnt fly as stated..
