Garret T53 or T45
 

I might be getting a T-sereis Garret T53 or T45 to boost my dad's underpowered 3.4L V6 when I'm going on vacation back home.
Which one would be better? i don't know the A/R's but damn those things must be big, or should I get the T42?
I can get them really cheap.

A/R's would be helpful, maybe along with a target goal of HP

I can't get the A/R's :(
But damn both look very big.
I read somtin' about a A/R of .070 on the T53, but I'm not sure and I don't know if it's the compressor side or turbine.My goal is over 250 hp at least on that underpowered engine ... it's rated at 160 hp.
I'll be chipping the GM ecu and already have the software eeprom burner etc. for it. Only need to get a 2 or 3 bar map sensor to get rid of the MAF.

hmm, those turbos would probably be a bit overkill if thats your goal, I bet if you look at a compressor map the thing really only works well at 12-15psi @ 3-400hp.


Duel feed from both banks? or single side feed?
