Which GT45s turbos do I purchase?
Which GT45s turbos do I purchase? Hey guys,
Looking to do a twin turbo buildup this winter for my 4th Gen Fbody. I've been reading a lot about the ebay turbos and intercoolers. I've even seen a video that was posted here about a Nova with twin GT45s making over 800RWHP. Not to bad at all.
My question is, which GT45s do I buy? There seems to be quite a few on ebay. I'm looking to make 800+RWHP. I currently have a stock 6.2 L92 motor that I'm going to be using for now. Then once I get the turbo system running right I'm going to take the engine back out and build it.
Here's one that I was looking at on ebay...
Compressor Size: Inlet = 4 3/16", Inducer = 68.7MM, Exducer = 97.8 MM, Trim = 69,A/R = 0.66, Intake (ID / OD) = 2.25" / 3.25"
Turbine: Outlet = 4", Turbo flange = T4, Downpipe flange = 3.5" V-band, Inducer = 87.4 MM, Exducer = 77 MM,Trim = 92, A/R = 1.05
Thanks in advance.

I got a tc78 with about 30 passes on it ill sell anytime after dec 10. 700bucks
But man, i know im a cheap *** but dude ive been down this road before so dont get mad at what im about to say..
Just think you spend 300-400 bucks on a ebay unit (when for less than a 1000 you can have a good quality unit with a warrenty), build a DP, get the oil lines and the inlet coupler and all the good stuff done. Then a month or two later it craps out and you get a different turbo (and spend another 300-400) then you have to do it all over. Or the intake blade spinnie turbine thing shatters, there goes your motor.. Or the oil seals blow out on a hard pull and your 100 miles from home.. Dude all of this stuffs happened to me and now i just buy turbonectics or precisions and i never have a problem. And i make alot more power!
Im sure your going to be just like i was and go with the ebay one. Your learn though

Anyhow, I sent you a PM.
Don't let anyone steer you away from the gt45' or (y2004k) turbo...its a solid unit.... look it up. theturboforums.com...4 years of posts on it and not one failure......and FYI its the same physical size as a few of the masterpower t4 turbos so if you win the lottery down the road you can just bolt the new turbo on your piping

I was wondering if I were to purchase two (2) GT45 with the specs that I listed in my first post, would they be a good setup for twins on a 6.2L.
I just want to know, are these good size turbos for a 6.2L or are they just too big? Planning on making 800-1000HP to the wheels
