Anyone running a GT4094r??
Hey guys,
I am about ready to purchase a single turbo kit and had the GT4094r as the one I was going to get. I called up RX7 store and he told me that the 4094 is too big for my horsepower goal. I was looking to make a solid 450hp @ 15psi, but my overall goal is 500-550hp. He told me about the t04z but based on average numbers on the forum its not a solid 450 @ 15psi you would have to run at least 20psi?? Now, would the GT4094r truly be too big? It is really that laggy that it won't be fun on the street?? I have a pineapple racing medium street port and was thinking of a .95a/r for the GT4094r housing. I will be running pump gas and will have water injection and all that stuff. Any help would be appreciated! P.S. I live in Colorado where the air is a lot thinner here if that makes a difference. Thanks

I would go with the GT over the To4Z, higher nickel content turbine housing, and cheaper to replace chra if you blow it. Performance should be similar between the two, maybe a tick slower on the GT as its a big shaft turbo( more durable however) If price isn't an issue then definitely GT. We have the GTX4202/4294R in stock too...

Honestly I never made a full pull on the dyno below 18-20psi. As we were having such bad boost creap. I will go back and get a chart to post. I was thinking it made around 450 at gate psi (15) but started to creep bad. But I do know 550 isnt an issue!

Wao I have no idea why people are saying that the turbo will not make the HP goals you have. I have a GT4088R and made an easy 447 @ 15. I didnt tune past 15 I didnt get the watermeth in time for the tune. Tuner Said that we will go up by 20hp per pound. All im saying is if he has a good setup and the pineapple ports are good he should be fine. And ATP is a great Garret distributer.

SO shifting gears from gt4094 to 6768 precision billet bb.... I have two options for a divided housing an .81 or 1.00. This car will be for street with highway pulls. If I had to choose between faster spool or top end I would choose faster spool. The thing that is confusing me is that I am 4000+ in elevation, so if at sea level I would choose the .81 but since Im higher in elevation should I go bigger housing??? Thanks guys

i wouldnt get the .81 if it were me. you will hold back that turbo in the end. if you want the best boost responce the 6765 with a 1.00 is very good. but for overall power the 6768 in a 1.00 or the 4094r in a .95 or higher. all of these turbos will hit 440-450whp at 15 psi. its when you get past 25psi where the 6768 and 4094 will walk away from the 6765.
