6boost With Internal Gate 3076r

[sriver killer]

Hey guys

ive got an r33 rb25det, 3076R

ive just thrown on my plasmaman and am looking at upgrading to a 6 boost manifold.

i'm upgrading my rear housing on my 3076 to .84

and have the option of going external or internal gate

the best option seems to be external gate with the 6 boost, with a decent wastegate.

i'd prefer to keep internal gate. if i can get a similar result. without many hassles

does anyone know anybody that has done this already? am i wasting my time?

looking to hit high 200's with this setup.

You seem to have answered your own question. From a technical perspective, a manifold that allows more efficient flow and cylinder scavenging is the thing to have.

Also an external gate properly set up will offer better venting and boost control.

There was a comment from Al who wants to go to virtually the type of turbo system you ask about, from an IW, collector style manifold on the basis of boost control and efficiency. That would/could open up the option of using split pulse too.

But there are many people easily achieving 400 rwhp +/- 15 using OEM manifold and IW turbine. A very tidy result at significantly less outlay. And it works superbly on a street car. If you were keen and capable, it is possible to smooth some internal sharp edges/restrictions in the OEM manifold too. Unknown exactly how much advantage this gives, but every little bit would help.

If you were chasing higher hp and using a GT35 turbo, then I'd have no hesitation in going 6boost + EW.

For me it's a question of performance target and budget.

I have a r34 with a plazmaman, with 3076r with stock manifold IW and making a easy 300rwkw on 18psi

I think provided you supported the turbocharger/dump pipe/exhaust system with factory style bracing a cleaned up std exhaust manifold would work fine . You have one already and it will look more factory obviously because it is , if you can use some of the std heat shielding more of the above .

Exotic manifolds are nice but the exercise can be involved and expensive for a road car , plenty of people here have simply bolted those turbos with a spacer on the std manifold and got more than adequate squirt from the retuned engine .

Real good bang for buck and if for any reason you had to return the car to std its a lot less work to do so .

thanx for the feedback guys.

The main factor that i am interested in going to a 6 boost style manifold is that i love the look of the turbo sitting up high.

plus its only $500 for the manifold, aswell as my own time in fitment and fabrication.

i know i can get the same result from the standard exhaust manifold and keep internal gate,

i honestly didn't think that i am forced to go "external gate" just to use a 6 boost.

please tell me where your getting a 6boost for $500..

coz i want one too!

You probably wont be for long when he finds out you are telling people you got it that cheap.

I also recall they can be made with no gate extension.

[rad100]

yeh i would be removing the price..

who ever said that i would be getting one new off 6 boost.?

buying one that was bought for a project but never used.

I was quoted 1500 ball park for a made to order 6 boost, by them. At the moment pistons and rods are my priority for dollars.
