No, this isn't true. Buschur himself switched to a T3 from his Mitsu housing and gained power, 20 to 30 whp IIRC. You can find it from back in 03 or 04 if you look.

 

hmm, i'll do some searching.

 

good solid numbers!! this is on AMS's dyno? so u made about 19 more whp with 1 psi mroe boost than me on a slightly bigger compressor. i want to convert my car to e85 but we have none around me in ny

 

Good luck. But, if you look at the DSM mani and the T3, it isn't too hard to see why the T3 would outperform the DSM at high flow.

 

Im not sure on what you have to convert yet just to run E85, from what i have seen/read you can just dump it in, tune, and go. I've been bugging AMS a little bit b/c they have been doing testing with it for about a month or so. I will probably get a E85 tune if i dont have to replace all the fuel lines. I have a Mobil 5 miles away that charges 2.06/gallon so it would be worth it even though you do burn more fuel
Edit, yes it was on AMS's dyno

You have the ATP kit right? If so I'm sure the making of less power has to do with the turbine housing.

 

Nez, go E85 and you'll never go back. I ran a 3076 and have now switched to the 35R because of E85 and 26 psi of boost. My tune is crap because I am always traveling and never home to finish it, but E85 makes it pull like a jet on take off.

 

and u have to change all the fuel lines and the rubber seals on the injectors to run e85.

and the less whp is due to a slightly smaller turbo. i just talked to FP and they said the difference is 20-50hp from your to my 3037s. but yes my housing is said to be restrictive but whatever. i ported it and matched the gasket so im not so sure its all that.

also figure u have a 2.3 so more displacement = more power. also u have 1psi more then me, which makes a big difference sometimes when running bigger turbos.

 

Yea, you really can't go wrong with a big turbo on high octane fuel that only costs $2. I just want to make sure none of my fuel components fail if i run it a lot. How long have you had it in your car? Did you change anything besides the tune?

 

Yes, a GT3037 is simply a Garrett GT3076R with HKS' own turbine housing (possibly compressor housing too but I don't remember). HKS has a few different A/Rs available for their turbine housings, all of which have a T25 inlet flange (smaller than T3).

In the past there were a few different compressor trim options on the HKS GT3037, don' t know if this is still the case. Check their website.

Garrett sells the GT3076R in the largest trim possible (56) since demand for the smaller trim compressors was minimal. The Garrett turbine housings for the GT30R all have a T3 flange. These are the same housing castings as used for the GT35R and they come in 0.63, 0.82, and 1.06 A/R.

 

A lot of the E85 tuned cars haven't changed any rubber seals or lines.
Yes i agree 1psi will make a little more power on the big turbo. Good choice on porting the hotside The 2.3 will only help more with spool up, not so much power. Overall you'll make power easier up top with the 2.0 on these larger turbos.

 

In some cases it makes it diabolically difficult to know what it is you're dropping down major bucks for. Confusion over turbo nomenclature is rampant, and the vendors usually ain't talking about what's in "their" super jammy turbo. They want customers to think their stuff is totally exclusive when in many cases, it isn't.

Not saying that's what FP does, just a general statement. In fact their turbine housing for the "FP30" is quite nice really.

 

On what fuel u ran it with? C16, C16 with meth, 93(or 91) with meth, 100 or 100 with meth?

 

Sorry to ask a newb question, but is the GT35R or GT3082 a good turbo on a IX with cossie cams for use in HPDE events? My final intention is to find a good turbo kit on stock IX block with cossie cams to put some serious hp and tq to help in HPDE events...

 

I changed nothing but the tune. It takes a bunch more fuel, but it is well worth it. I'll eventually run it at 30 psi daily and see what it feels like.

 

It was on 93 with meth.
