curious to see the pipe routing. this mani could make a splash in the GTR market especially with the big HP going front low mounted turbos.

We are interested in working with a R35 builder to construct one of these manifolds for them. If you run into anyone who would be interested, send them our way. No GT-R tax (for the first one

)

I am curious...with the throttle bodies in the front you would have to have 90 degree couplers there and another set of 90 degree couplers to get down into the intercooler ....wouldn’t they be more restrictive to the flow than the OEM manifold ...even with a NA setup with filters located there the 90 degree bend would have to restrict flow over the OEM set up.

We wont have any 90s we will be going straight forward into the top of the intercooler.

But if someone did want to put elbows on there, its not really going to make a difference. Your average turbo system has tons of 90 degree bends including the compressor housing outlets, inside the intercooler end tanks to enter the core, and all the several feet of piping to get around the core support. You could most likely end up without any more bending than the stock location throttles if you plan your pipes well, possibly even less bends. But the way we are using it, we will have eliminated several bends and at least 4 feet of charge piping, if not closer to 6 feet.

Attached some examples of our DE billet manifolds in use.

Those pictures make sense. Just a redo of the intercooler for the piping to come out the top.

Yup we will use our existing intercooler kit and just make a custom end tank for this build.

I can't wait to see Justin's car up and running with the new intake/intercooler setup.

I was thinking from most of the other turbo kits just the difference from their location going to the stock location ... to add this manifold to a existing kit ... you would add 4 90 degree elbows ... I guess it wouldnt be a big difference and you prolly gain more from the intake design than the flow would hurt you.

You could just buy a new intercooler and eliminate that issue.

Ya it won’t make any difference. You’d want to toss all the upper piping any kit came with and start from scratch. You can go straight through the core supports like we do then behind the rad right into each throttle. All the other kits snake around the outter sides of the core support and fender liners and have a ton of bends anyway, so you can end up with something better off or certainly no worse than you already had. Although we don’t really see a reason to not just go over the top of the rad and make it much more tidy. All the core support components bolt in and out, so no permanent changes to the vehicle need to be made.

any idea how much performance over a ported upper and lower intake this would make ? ...those was seeing 30 ish hp/tq with a boosted car ...to convert over would be intake and new intercooler which would be 4.5kish ...granted it by far looks the best

Is there a price listed for this manifold yet?

Cuz if your $4.5k doesn’t include the manifold, there’s no way it costs that must just to buy a new intercooler and intake piping over the radiator.

jwick · 12-28-2018, 08:56 PM

Phunk- Where are y’all putting the MAFs or would this have to be density tuned off a new MAP sensor?

In this thread he said the intake was 3k ...and if you replace the intercooler to match it I would assume 1200 ish .....then retuning etc ....this would be a pricy upgrade over a ported upper and lower if the performance gains are similar
