I'm trying to decide on a new turbo and I'm looking at this one.

http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=GRT-TBO-048&Category_Code=TBN

If I get it it will be the .78 divided turbine and anti-surge compressor. It will be going on a stock displacement 420a looking for close to 400whp.

Any opinions on this turbo or suggestions of any kind?

nice turbo, slightly pricey.

If your spending that much money, why not look into a 30r?

I have that divided 0.78 A/R with a different center section and compressor. ATP is a good company. I have been happy with the quality of the housing and other parts purchased from them. Be sure to buy your V-band flanges from ATP. Flanges on E-bay and many other places will not match that housing. They also include really beefy clamps with self locking nickel alloy nuts that will not gall when overtightened. They did try to send me some cheaper substitute flanges/clamps once, so you do have to watch them (they kindly replaced them and paid shipping). I am a believer in ball bearing center sections though. I can hear my compressor spinning for at least 30 seconds after I shut the engine off (GT3071). My old jounal bearing turbo never did that. That is my two cents.

i hope you plan on getting a divided manifold made to match the housing otherwise its worthless and pointless to get that housing to mate to a cast log.

If you want to check out the capability of the GT3076R, I would scour the net for dyno data on 4G63 Eclipse and Evo 7-9 upgrades. I believe that 400 WHP is probably at the reasonable max of a GT3076R. It might leave you a little short, but should be close. Those selling BB turbos tell you that they will spool faster, be more durable because of tighter clearances, and deteriorate your oil more slowly due to their reduced oiling requirements. It sounds reasonable to me. You have to be a little bit careful. Some turbos have two ball bearing assemblies. Some have one ball bearing assembly and one journal bearing assembly. Just make sure you know what you are buying.

If you get a divided housing and put it on a non-divided manifold, you will pay a penalty. Some energy will be wasted as the exhaust slams into the flat face of the divide. If you never intend to make a divided manifold, I would avoid the divided housing.

That same turbo is on this site for 50 bucks cheaper and i have done business with them before.

Yes a GT series turbo will spool nicer BUT There not even in the same price range

ill do some looking for yea to see if i can find a deal

661hp & 463tq Worlds highest hp 2gnt soon to be the fastest

Garret GT turbos are pretty good turbos IMO, fast spools with nice builds. If you shop around you can get a good price on 1.
