Just thought I'd put my 2 pence in.
Going from a K14 which you literally have to keep strangling its neck to keep it on boost through the gears, I took the plunge and bought a GT22 VNT.
Indeed I agree with the cornish farmer and the tall ginger....they are a pig to setup up and the amount of times I had the turbo on and off the block was at least half a dozen. Was close to the point of sacking it off and selling it due to getting really annoyed with it. Then once it was together and holding its boost back (had major problems of it pinning a 30 psi boost gauge) it was an absolute animal even at the first 15psi.
Its still not right and needs a few tweaks and like Darren says you need to be adjusting and fiddling all the time to get them setup correct. Mine at the moment will pull fairly well but then backs right off the power once you reach the higher revs.
This probably hasn't helped but I am a believer in a newer generation, efficient turbos. They spool really well. Depends on your diving style. For me its early spoolers and not having to rev the engine off the gauge (though it is nice from time to time).
Good luck with your decision though!
