Prototype billet aluminum intake manifold thread

[biglou911]

Why not build same type of manifold supra and gtr guys use ?

[wazzu70]

A lot of people only want the center feed. The side feed can work fine, the plenum shape just has to be such it actually feeds the front cylinders.

I have never seen a GT86 swapped to an N54/55. Thanks for sharing...

It's the same manifold used on a 2JZ as posted above and you're welcome.

[wazzu70]

I looked up the engine bay on the GT86 posted above. The plenum on that manifold is significantly different and a much better design...as are most of the aftermarket manifolds for the 2JZ.

that doesnt look like the enkoo racing 86 as there car is a tube chasis pro-mod with fiberglasss frontend

[wazzu70]

Makes sense given the timeslip! Anyone got any current photos?

[Commanderwiggin]

[dburt86]

Yea they are pretty good at not having too many photos of the cars other then the outside.

249 in the quarter with a 2J? Good lord.

[wazzu70]

Thank you for the pictures. That intake manifold has a significantly better plenum design. The inlet is further forward and has a smoother transition to the main plenum volume.

These ppf intakes look to be pretty decent. i know they dont have that billet goodness but with that price point
one cant really complain

How much dat be usd

[someguy2800]

That is USD. There site lets you select euro, kroner, or USD on the top.

Hey they have stuff to do a 20 degree motor angle in an E36. Someone needs to buy this

and this from me

[Butters Stoch]

What are those 530 and 320D trans ? What's the benefits ?

[someguy2800]

I think the big advantage is fitment for a big top mount turbo. Mike ran a diesel trans at one time but broke it.

[wazzu70]

Those transmissions are rotated so the engine sits more vertical.

Nick,

I looked at both sets of pictures, and I honestly don't see what you are referencing.

The runner lengths are ARE different, as the power target is much higher with the drag car, but I'm not seeing much difference with the plenum.

Secondly, Kenton is the ONLY person I know of currently building a BMW street car with over 1krwhp. He has already gone through a list of parts that most people would give a body part for, and is looking for the next step. He has shared what he thinks is a useful piece of hardware, based on the successes of other people that use it.

I don't understand why you are bickering with one of our brothers...

[wazzu70]

Adam, I was just trying to help make sure if people were spending 2k on a manifold that it performed as good as possible.

I understand the runner lengths are shorter/wider to help move the powerband up the rev range as you would want in a drag car. That makes sense.

My point was there is lots of room for improvement on the inlet plenum feed is all. I don't understand the concept of designing something from the ground up out of billet and just making it "meh." This is especially true for a high dollar performance part.

Im all for people pushing boundaries and experimenting. I think thats awesome and I wish I had the $ to do so. If I can help make that journey more successful for them by lending my experience I figured that would be helpful to improve the product. Thats all.

I completely understand.

[someguy2800]

I really don't see a problem with any of the manifolds posted.

[tptrsn]

I don't know if I really understand the intent of all of this intake manifold talk. Is it really for big power gains, or more for the coolness factor? The reason I ask is because so far I don't think I have ever seen results that show any of these manifolds make a lot more power in a forced induction application than something like an M50 manifold does.

Have I just missed it? Someone please enlighten me if so! And if it's mainly for the coolness factor, so be it.

[milKt]

A few here will rationalize an intake manifold project like this with "transient" pauer response changes
but the dollar to effective power ratio is Trump Money territory.

Other advantages include BUNGS. "/

This guy lol!

[tptrsn]

Bungs are cool, no doubt. Haha
