abes Posted January 17, 2008 Share Posted January 17, 2008 I have this guy who's selling me a pair garrett turbos for about $1200. My question to you guys is do I really need them??? They're T28s. They have super 60 trim compressor wheels with t28-79 trim turbine wheels and standard bearings.They're fresh out of the oven so it sound like a good deal. I want to make about 450 to the wheels but streetable. This is not going to be a track car, just a weekender. He's telling me there good for up to about 700hp.... What do you guys think................. Quote Link to comment Share on other sites More sharing options...
BirdmanZ Posted January 17, 2008 Share Posted January 17, 2008 Sounds like they are high mount twins and will not bolt up to the factory manifolds. Also, being that large, they are probably going to be laggy as hell. Throw a set of these on there. http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT28/GT2860R_707160_7.htm They will probably exceed your power goals and your spool time won't be much more than stock.

BirdmanZ Posted January 18, 2008 Share Posted January 18, 2008 I stand corrected. The "super 60 trim compressor wheels" threw me off a bit. The only problem i see is one of the turbos has the two bolt outlet on the compressor side and the other does not. Might be a problem if you try to hook it up to the factory charge pipe. These will definetly put out more than 450hp. Quote Link to comment Share on other sites More sharing options...
abes Posted January 18, 2008 Author Share Posted January 18, 2008 Anyone else??? Quote Link to comment Share on other sites More sharing options...
abes Posted January 19, 2008 Author Share Posted January 19, 2008 Has anyone else had any experience with a similar set up? Are they to big and laggy for the 450 range?? Quote Link to comment Share on other sites More sharing options...
Roostmonkey Posted January 19, 2008 Share Posted January 19, 2008 My first concern would be that they dont appear to be identical turbos. Eventualyy I'll be in the same market for a pair of upgraded twins and I plan on the GT2860r-5's. Direct bolt-ons and easy 450hp with the other typical supporting mods.

Careless Posted January 19, 2008 Share Posted January 19, 2008 the one on the right (polished one) seems to be a tad smaller in size, but looks like it has a larger compressor wheel. but maybe it's just the angle of the photos because it would be way too hard to tell from where i'm sitting.

abes Posted January 19, 2008 Author Share Posted January 19, 2008 He told me they're both identical. He cut the flange, and polished one but never got a chance to do the other. He said that he cut the flange because he wanted to run custom intercooler piping. Supposedly, they should bolt right up. Do you think they'll have more lag than the gt2860r-5's?? A pair run about $1600 plus or minus correct?? Quote Link to comment Share on other sites More sharing options...
AKWIKZ Posted January 20, 2008 Share Posted January 20, 2008 Those are Nismo N1 turbos. If they are bushing then they are R32. These are more or less comperable to HKS 2530's, but without the bearings. They will put down 600hp. I would spend another $300 and just get the 2530's though as $1200 for non-bearing used Nismo units seems a bit high. I would offer him no more than $800 for the pair personally. And only if they are very tight. Brian Quote Link to comment Share on other sites More sharing options...
synthtk Posted January 23, 2008 Share Posted January 23, 2008 I would just get the GT2860's either the -7 if you want better spool or the -5 if you want more power. My current planned turbo upgrade is to get -5s. I <3 Garrett Quote Link to comment Share on other sites More sharing options...
Guest rbz Posted January 31, 2008 Share Posted January 31, 2008 I just changed my stock twins for some garrett gt28's. They spool up a lot faster than the stock t25's now that they"re ball bearing. Haven't dinoed yet but was making 350 before. I'm sure I'll do better than that now before I run out of fuel. (stock injectors for now) Quote Link to comment Share on other sites More sharing options...
