Rb Hks Cast Low Mount Manifold

[tridentt150v]

Mine is tapped for both t3 and t4, so if yours is the same then it would also have enough meat on it for this [a lot are already tapped for both, but some stood behind the door and so are only either t3 or t4]. Setting up for both flanges is a simple job, any machine shop could do it in a couple of hours and if you have your own tap and ie set you could do it yoursef pretty easy. They are one of the best flowing manifolds you can use and $500 is a good price..

would this work the same as a twin scroll t3 manifold like from 6 boost? also can u include the heat shield and wrap? cheers

[32_Dave]

i wouldn't have a clue how it would compare with a 6boost. but car makes 355hp on 15psi with a 3076 which seems to be slightly more then SOME cars with same setups on 16-17psi.

yeah ill leave it wrapped, and include the screamer pipe (its wrapped together with it)

mmm can anyone shed some light as i have a twin scroll t3 flange gt35/40 and i need a manifold that will work effectively with a twin scroll turbo

[waxracing]

Yes it will work well, I have seen one on an rb25 and it made impressive power, its a twin scroll so no issue there

[jet2nv]

im just still not 100% as a true twin scroll has 123 cylinders into on side of the turbo flange and 456 into the other where this looks different i need to be 100% as if its not a true twin scroll like a 6 boost for instance then it defeats the purpose of me having a twin scroll turbo

I used to own one of these, and there is internal casting that does separate the two sides from each other from memory. A photo of the outlet can confirm.

It is divided both on the turbo outlet and the wastegate port.

[jet2nv]

are you able to put up a pic of the flange i

Even the stock rb25 manifold are divided on the flange but its not a true twin scroll tho

1 1/2 of the flange needs to be from 123 cylinders and the other half the rest

[jet2nv]

yea its not a true twin judging from the pics if found 1 and 2 merge into the 3rd cylinder where true twin scroll are all separate till they meet the turbo flange

other than thread crap, why not just ask or do some research. The internal diameter of the pipes grow in diameter where the last meet the next, which dont cause an issue. They have been designed to work, and do. If you are not happy with them, dont comment here, its a for sale thread.

[jet2nv]

im just trying to make sure its twin scroll 100% before i make my purchase from him, I was hoping alot of people with knowledge would comment on this thread, Ive done research and searched alot and from what ive found its not a true twin scroll so it defeats the purpose of having a twin scroll turbo its on the basis of a stock manifold just better flow

all cylinders need to meet into into where the flange is for a twin scroll turbo to be affective im guessing these manifold are designed for a old style t4 flange turbo before twin scroll rear housing where used

[jet2nv]

it explains it all here between equal length twin scroll and cast like the hks ones

It is a twin scroll but does not feature a single merge collector for all runners.

You can't compare a HKS manifold to a simple log style as it sits somewhere between the two types in its design as the runners are blended far better than a basic log. It has shorter runners than a 6Boost which may be helpful for better boost response but who knows how much better?!?!

Last I checked 6Boost are not exactly equal length (although they are close), as Kyle has stated that as long as you are close enough it makes almost no difference.

For a twin scroll to work you need to separate the front 3 cylinders from the rear 3 which the HKS manifold does for both the turbo outlet and wastegate port.

its sold pending pickup this weekend.

thanks for all the guys with the info
