Greddy T67-25G

[wogzilla34]

I'm wanting to put a set of these on my car and want to know if i have to run 2 external wastegates??

[Aggroman]

yes

[Ben C34]

You don't have to do anything. You could run no wastegate or make a crazy manifold and run one wastegate.

But the sensible option would be two wastegate.

[wogzilla34]

Thanks.. I know there is a greddy manifold that run td06 and t67s and only run one wastegate.. That would still work fine yeah

[GTScotT]

One gate will work, but the design will be difficult.

So, when are you expecting full boost with 2x T67? Before redline, hopefully?

[Tonba]

There are so much better turbos out there then the T67. That thing is OLD SCHOOL tech. 20-30 years old now.

Much better options out there today.

I had one on my evo about 3-4 years ago for about 2 months before I got rid of it for a HTA turbo. Picked up 30kW and about 700rpm in spool. T67 is a dog.

the spagetti Trust manifold was designed with just one wg, however there was a simplified version that utilised 2 wg's..... honestly unless your drag racing, or have a hard on for t67's you might need to look at a different combo.

The evo is a small engine to push that much air, but I have seen billet T67's run up to 400kw, certainly not the dog you believe it is, but I agree, there are better options these days if you are willing to spend more cash...

I think you should start a new thread, this one is old and confusing already

Please, as soon as you go billet, you no-longer have a standard GReddy T67.

I stand by my statement, in that the T67 is a slow spooling nugget. I have tried it with a number of different combos, and it just didn't work (cast Trust manifold, 8cm housing, Trust tubular manifold, 10cm housing). I was better off with a stock frame billet turbo.

I think there are FAR better turbos out there these days. I would take something like a GTX3576, HTA3582R or even a PTE6262 over one anyway of the week.

I don't BELIEVE it is a dog, I know, because I have used the darn thing.

[XRATED]

That's interesting....

I really enjoyed my t67 25/30 r32. I thought it was well matched to the engine/gearing/use of the car.

And was a lot better than the two PT turbo's I had tried before!

[JH32]

1 T67 on a 3L is probably a little different to 2 T67s on a 2.6L

[Mick_o]

LOL! Enjoy your 300rpm range of useable power..... Even then think im being too generous

Wait did I say useable?

Just offering an alternative view on t67's.... after Alex's distaste for them.

[Mick_o]

T67 on a 3L 6cyl woulda been fun for sure

But a nugget on a 2L 4cyl

[WMDC35]

I find 1 T67 on a 2.5 isn't bad at all, will also be trying it on 3l once the 25 is dead.

Yes, it was a nugget. I can get a HTA3582R or GTX3582R to spool as fast as a T67 on my car... and it makes more power everywhere..

So I don't understand what fuss behind the T67? The compressor is cast (ie heavy), with aero designed 30 years ago and is only 60mm in / 78mm ex. That's a similar size to the GTX 76mm wheel which is a lot more efficient.

The T67-25G might have been respectable 5-10 years ago, but it is simply old technology these days...

[XRATED]

yet it still performed better (everywhere) than a ceramic bb core, billet comp wheel, inconel turbine PT turbo? hmmm... it's old, but it works.

[scotty nm35]

At 3 times the price the HTA should spool 3 times earlier.

I sense a lot of butt hurt about HTAs, Mr Scotty
