I have the Greddy kit as well as cams and utec and every other bolt on possible and I have yet to see a faster evo period with out a stroker block. A few of my buddies at RIDE in daytona have the gt35 kits and I have better 1/4 mile times and e.t.s due to the sheer size of the turbo and I can not stress enough that it is all in the TUNING!! The t67 kit gives me 450hp on pump and 500+ on race fuel, and depending on how you drive it should perform just as good as any other evo turbo upgrade kit on the market.

 

450 with pump? pretty impressive. When does that get full boost? Got dyno sheets?

 

did greddy ever solved that manifold crack thing. i heard from almost everyone on here that has the 25g kit, has had their manifold crack due to the lack of support mounts for the manifold. i still would go with the gt35, just love the crazi spool up sound from the ball bearings.

 

I would only go as far as a 3076 on the stock block if you don't mind lag than the 35r is okay, but the 25g is garbage compared to the GT series, i've seen them all in action and i wouldn' waste a cent on the Greddy kit

 

well here at CFT Rolo tune one @30psi '547hp/458.tq the kit is not that bad at all!

Rolo setup(547hp+Greddy kit) on stock engine a nice daily driver evo!!!! is not a GT35R!!! but it gets the job done !!!
FOR THOSE WHO DON'T BELIEVE on (Greddy POWER) @ 30 psi

 

Were you using a 10 cm turbine housing on your T67 cause the 8cm T67 turbine will not make that sort of power. It seems to choke at 30 psi and at race gas, its maxed out on 520 at the wheels on a AWD Dynojet.

 

I really want to get the t67 but i dont know what exactly my car needs before I get the kit. And im concerned about the drivability can i drive it daily? Cuz its my only car.
