Default True twin scroll headers who sells them and are anyone running them

Hey guys,

Looking to get some twin scroll headers for my setup. This would be for a GT series turbo (i.e GT35R GT40R). Was wondering if a company makes these as a stock item? i know UR make them as a customer order, but was seeing if anyone else make them and what there selling for.

Also does the position and length of the upipe determine the pulse. or is this all determined in the length of the runners that make up the header??

I have a rotated setup and thus want to keep it that way...

Thanks in advance

If the rotated setup is the same as the OEM vf36/37/42 setups then here is what I know:

There is a JDM OEM twinscroll setup which includes a factory equal length header and split twin uppipe. Aftermarket versions are available (search eBay) but I can't see you possibly getting any gains from it over the OEM stuff. The aftermarket UP is identical to the OEM twinscroll UP except the aftermarket version is polished stainless. And the OEM Headers are top quality. When I say top quality... they're stainless steel tubes wrapped in heat shields with thermal foam blown inside the shields for added heat scavenging and thermal containment. The aftermarket stuff doesn't have any coatings, and if you were to coat them I would say the factory stuff would still out perform it. But the OEM stuff isn't winning any shows in the looks department.

And it is the combination of the EL headers and Split UP that provide the smooth and even pulses.

The VF36 ect factory setups have the turbo mounted in a stock location i.e the inlet passes through/ under the intake manifold. My setup is rotated meaning the turbo sits in a different location (see pic)



Now if i went with a stock twin scroll, i would have to make another upipe to suit my rotated aplication. Now would this affect the pulses? and thus turn a twin scroll header into a equal length header.

The problem i find with the OEM header is that the diameter is too small, thats why i would be after an alternative.. The UR is what i would like to use but its only made for LHD cars, and since mine is RHD the turbo hits the sterring column resivoir...

isn't it kind of pointless to use the twinscroll headers if the turbo housing isn't twinscroll itself?

E.g. wouldn't you want something like a 37R or a 42R? I'm not sure if you were just using those two as examples of what Garret makes or something you were going run.

I know APS makes twin scroll headers and they're Aussie, so it's possible they make some RHD headers as well. However, I don't know if those will work for you because I'm stupid.

There just examples, and yes both GT35R and GT40R come in a twinscroll version.

ASFAIK APS wont sell the headers on their own (i.e kit) and they dont work with a rotated setup (someone prove me wrong)

You're looking for a true twin-scroll to go to a rotated turbo, not bolt-on.

The only company I know of is APS, and you have to buy their turbo with their twin-scroll uppipe.

They are a one peice header and have a divided inlet T3 flange or you can get them with a divided inlet T4 flange. You might be better off trying to order from PDX Tuning since they are pretty close to GPMoto. I have had difficulties trying to deal with GPMoto. I believe they are around $900-1000.

Ok.. Well they dont post prices so I was guessing and going by what I say on the price list at the shop a long time ago. We used to sell GPMoto Parts.

$700 is great but even at $900-1000 it would still be a good deal considering what you get.

So I take it you live pretty close to them or work for them? I have a few people who would like to get one of their manifolds. The problem is that GPMoto is difficult at time to get in touch with because they have so many projects going on now since they are working on Volvo stuff.

^^^ i wish i knew enough to turn a wrench.. im an hour away but i hang out at their shop alot (i am a master push-broomer!). they do alot of side projects but still have time for suby stuff. ive been to alot of the local shops around the oregon area and i felt like i was treated fairly at GP... so thats why they get my business.
