INASNT, Evan of PSI Fabrication will make a tuned length manifold from steam pipe for $1200. His stuff is a work of art, and he has a very good reputation here in Adelaide for high quality work. That is with a T3 flange, he can make adaptors to GT25 too if needed. Alot of his work has been featured in HPI and Zoom, the only downside is he can take a while.

kool, found guy in melbourne who will do it for around $1400 in steam pipes. I will get the comp cover polished and a polished heat shield for the turbine side 2!!

Im pretty sure this photo is indicative of the wastegate/manifold setup.

[JNR24]

Who makes that manifold!!!??

i want it!!!

[JNR24]

or is that a stocker? issan one?

[Roy]

Not positive, only pretty sure that its a modified R33 manifold which has been HPC coated

[Guest INASNT]

its from unique autosports

[JNR24]

cheers guys.

***n good idear! should of thought about that before.

[Roy]

...who buy/source the kit from...GCG

That's one HUGE turbo!! Is that the GT3540?

[Guest INASNT]

the unique 1 looks like the stock manifold but just got a another pipe welded on for the ext gate, then its been hpc coated. It wont work good for big power as they are not equal lenght runners feeding into the turbo intake.

[Roy]

Its a 600hp turbo, they seem to think the 38mm wastegate and exhaust manifold will work well with this turbo, so whats considered big power???

[Guest INASNT]

600hp is big power, but they thinking it will work well and it actually working well is a different story

[EVOIV]

I still think a 38mm wastegate is too small for such a large turbo that's rated at 600hp. I think it would be equivalent to the HKS GT3240, as I believe that is rated at 600hp too? And I'm sure the kit for that turbo comes with the 50mm HKS wastegate, at least. The smallest HKS wastegate is 40mm.

[Roy]

My thoughts are the biggest problem with that manifold is hot spots that may increase the chance of warping the manifold. (Can you tell i have just warped my factory exhaust manifold)

I would tend to agree with you, and may have even thought that a 38mm wastegate is a little small, but the people that screw theses kits together have more experience with turbos then me, and would understand that the setup is a compromise based on cost.

Thats not to say that it will all end in tears, it MAY mean the turbo/engine performance isnt being maximised.

[Guest INASNT]

for the price difference of a 38 to 50mm wastegate i would folk out the extra $$.

Anyone know off anyone using this setup on an rb25 ?

Any constructive commment appreciated, thanks guys. :uh-huh:

ive got this set up on my car. actually got a gt3540r the twin ball bearing one with 42mm gate. its made over 500rwhp with a rb30. i will let you know friday what i wil be making as thats when it goes onto the dyno

[Steve]

RNS11Z, good luck. It will be an interesting read

[EVOIV]

Yes, good luck! That turbo seems very large by all means, hope it's not too laggy for street use.
