IX gt3076r maxed out?
#31
Unfortunately I've never seen any testing of where people ran the gt vs the GTX 3076 at 30psi+ range.
Whats the smallest 35 you would recommend to keep my current power curve yet pick up 75whp ? Obviously since i'm buying new i'm assuming a gtX35 but with a t3 turbine and vband dp? Pump gas power isn't really a big deal since i'm spraying meth.

Overall the GT3076 is a pig for spool vs power. About 7-10 years ago it was the turbo to get. However that time has past (personally I always thought my old school 50 trim+meth@30 psi outperformed most setups, however that's a story for another time). With all things being equal I think the HTA3576 in a .63 will prolly spool similar to what you have. However to make 500 WHP on a mustang dyno I really think you need the .82 housing with larger cams on that turbo. This as you know will make it slightly laggier. However it shouldn't be too bad IMO and very live able in a daily environment. Good luck.
looky what I found... gtx3076 vs gtx3576 http://www.lancerregister.com/showthread.php?p=4378878

On this dyno comparison was that a 3076 with a .63 housing?
- GT3076 has never been a good pump gas turbo because of the restrictiveness of the turbine wheel. However C16, E85/e98 people are able to coax an .82 housing to 50-52 lb/min range because of the anti-knock properties of the fuel.
- When you see the dyno comparisons between the GTX and the GT3076 you will notice there isn't much difference. The turbine wheel is the issue. I would be willing to bet the the GTX doesn't make much more power maxed out than the GT3076.
-There are LOTS of other turbos that outperform it. Case in point. Holset HX40 will absolutely blows it away. See below. Same car, same dyno, no other mods besides a turbo change to a Holset HX40 in a T3 .55 housing. 2.3L DSM, HKS 272 cams. Its also important to note that the GT3076 would NOT boost any higher than 30 pounds. It was done.
- I am not saying to go with a holset. However you can see how under performing a GT3076 is when a 20 year old diesel truck turbo blows it away. The HTA, EFR, and GTX turbos out perform anything a holset or GT turbo can make. Hence why I would drop that turd to a HTA3576 at a minimum. Or hell HTA3582 with give you some extra breathing room (but might be a bit laggier than you want)

The holset HX40 was on T3 .55 housing, and I believe the GT3076 was on a T3 .82. THe holset HX40 turbine wheel is quite a bit larger than even the GT35R and flows well in small housings.
EDIT: There are other turbos that do fit in your criteria. Such as the new PTE CEA 5858. However given the performance of the original 5857 and how un-impressive it was, I am hesitant to recommend it without more data on it. However, it certainly "can" flow enough to make the power you desire, just when, and how much boost is desired is the question. So considering it a big unknown I only listed the HTA/GTX 3576/3582 turbos. Tried, tested, and proven, and despite the price tag are probably the best performing turbos in their class (and I hate admitting that because I am not a Garret Fan boy)
Perhaps Aaron or someone else can spread more light on the much cheaper option of the 5858..that is unless you are not interested. Hope I helped.

The larger turbine wheel and better matched turbine to compressor wheel combo will benefit your setup.
for best results I would make these changes:
- 0.63 T31 4bolt
- move placement of wastegate to header
- redo your o2 housing to 4bolt

So my existing t3 .63 gt30 turbine will accept a gtx3576? If so i'm game...

the T31 is a T3 footprint so will bolt onto your manifold but doesnt have place for the wastegate to come off the turbine housing like the T3 5bolt ford style turbine housing you currently have...
GT35R has a bigger exhaust wheel than GT30R so it needs the Turbine housing which is machined for the bigger wheel.

While i'm glad to discover the gtx3576r. It also still chafes my *** to see people on my current dyno making 60-70 more whp on the same .63 housing with mild cams from dsms to sr20's. I guess with those cars the .63 housing wasn't a 5 bolt tho.

If lag is that important...then it is certainly is possible to make 500 WHP on a mustang dyno (570 ish dynojet) on the .63 4-bolt HTA or GTX3576 as Sal has mentioned. The .82 would give you some serious breathing room above 500 WHP and cost about 300 or so RPM in lag.

In regards to the EFR "reliability issues" - it seems like those have been resolved for some time now, of the units discussed here it would probably be the best. I am unconvinced that the GTX3576R is a great thing at this stage, too.

the 60mm 30R turbine wheel is the limiting factor, it doesnt allow the GTX billet 76 comp wheel to reach its full potential...
Now Garrett took the same billet 76mm wheel that flows as much as a standard cast GT35R’s wheel and attached it to the 35R’s turbine wheel and this has resulted in one killer turbo. On paper this turbo should now offer equal to or slightly less power than the GT35R, but spool faster due to its smaller and lighter 76mm compressor wheel.
Hence the current focus on this GTX3576R Wheel combo...
