Its time for the TD42 of mine to go from the N/A slug it is to a bit more power by stucking a hair dryer on her (turbo

I have a friend from the forum here ( you know who u r) who is going to do me a manifold for me (weld on a flange plate to a custom manifold) but i have to choose the turbo and the flange pattern,
What i want to know is i ain't going for a garett turbo simply because of the cash they want for them, have seen some turbo's on Ebay for less, and for what i do (weekend warrior 4WDing) i can't really see the point in speding into the $1800's just for the turbo itself.
I want to know if anyone can send me some links or tell me what to look for in regards to what would give good power and torque for the TD42 without having to rev it up real hard to get it onto boost or have it spool up well too early, would like to to be on boost at around 110K's on the freeway with still a bit more to go rather than run it out, want to go up hills in 4th or 5th rather than 3rd.
Any help or links to a turbo that would suit would be great as i am new to the turbo scene, Gas is no problem, can tune a gas setup without problems, but finding the right turbo for my thing, i am so not there yet

Thanks
