35R and 25G flows almost the same, so they can belong in the same sentence

Not to mention the $300 price difference, or the fact that you can run an Internal wastegate with a dual dump-pipe on one of them

 

That won't make near the power, though.

Regardless of the specs, I've yet to see a 25g match an equivalent GT35r setup on an Evo, which is all that matters here.

 

Perhaps I can answer that perfectly...

I was running the Greddy T67-25G -8 cm housing on my 2.3 stroker with HKS 280's. Full boost on the optimum cam settings was on 4100 rpm. I 'm hitting 22 psi ( my set boost on pump gas) at that rpm amd made 422 WHP on the AWD Dynojet. Spool up on this turbo is amazing and I can vouch no GT35R setups can come close in terms of spool up and response due to the rather small 8cm hot side and stroker of course.
To simulate a real world driving condition I had the pleasure to go against another friends evo running a GT35R with HKS 272 on 25 psi doing 441 ATW but full boost rpm in this stage was at 5100 rpm and we tried out against each other on 2nd to 3rd and to 4th. The verdict was just a consistent 1.5 car lengths holding out due to my quicker spool up and response despite his higher horsepower and better top end power.

I have since swapped to a GT35R setup with a new manifold and using the same cam timing full boost rpm on this setup is at 4500rpm, still 400 rpm later than the T67. I find the 35R a lot nicer to drive as you can definitely feel the rapid spoolup of the ball bearing and ultimately because I was chasing for over 600whp on race gas its still THE turbo to have...

The T67 maxes out at 32 psi making 522 WHP on race gas. The 35R made 640 WHP at 35 psi on race gas. Thats a world of difference.

For maximum response on the street and drivebility its the T67 but for all right horsepower but still a fun drive factor the 35R for sure....

Take your pick....

 

Ahhhaaa...You my Friend are just ignorant.


however i still would like to get more info on the 25g t67 this turbo sounds like fun to me since i like the highway alot more than 1-2nd gear sprints

 

If you want some serious power, definitely look into the built motors people are offering. For one, we have a 2.3 stroker short block that we sell. It is considered to be our Stage 4 Power Package System. Comes with forged internals, custom spec pistons, special coated race bearings, and of course we will have it professionally balanced and assembled. The result of the extra .3 liters of displacement bumps the remaining compression to around 8.8:1. The added displacement will obviously help when going to a larger turbo to be able to support extra power being provided to your car. This motor is rated at 550whp, which is in excess of 700 total hp.

But if a larger motor is not what you want or looking for at the time being, then a turbo kit such as the HKS 3037S Ball Bearing Turbo Kit would be my personal choice for overall quality and performance. It has been shown to provide more power and better response over the APS GT30 but obviously not still nothing like as large as the APS GT35r haha. The price that we are currently offering for the HKS 3037s Turbo Kit is $4,999 SHIPPED!!!! Price is Unbeatable!!

PM me if you have more questions. Thanks.

go garrett t3/t67ho it has the most potential of any t3 turbo made (including the 35r)
if you want a little better spool up go with a bb version to4r, 37r ect......

greddy's t67 is NOT a t67!!!!!!!!!!!!!!!!

 

Highway fun=GT35R!!There are some people on this board use stock block + GT35R(EVODave,Tim,Reaction CT9A,Jarrod)!!

 

stock block makin over 450 whp on mustang dyno is very possible. So you might not even neeed a new block.

 

Correct A real T67 will flow about 9-10lbs/min more...........

Also there are 12cm^2 (0.89A/R) Exhaust Housings available for the Greddy to make up that 100Hp difference between the two turbo's on top-end

 

I have seen it time and time again, on different cars, where both turbos are very comparable at boost preassures below, say, 28psi. The the greatest advantage of the 35R is its ability to run more efficiently at 30psi and higher

 

Just based on sheer size I would imagine the 25G would be able to make as much power as the GT35R. But keep in mind this is a 25G compressor wheel mated to a TD07 turbine wheel. The TD07 turbine wheel is an extremely large wheel originally designed for diesel turbos, mated to a journal bearing system, and a not-so-efficient compressor / turbine housing.

Honestly for efficiency, response, and spool up I would prefer the GT35R anyday.

Why is this thread comming back from the dead?

 

so you want maga top end and you dont care about spool.
built 2.0 with a gt42r is the answer

thats what the 800-1000hp drag hondas and evos run

definnately not a street turbo though
