rb26dett intake manifold and itb's on a rb20 head

[BrodyGoble]

Wow what a job!

After alot of work by westcoasthotrods and myself we finally have the rb26dett intake manifold with full itb's on the rb20 head while still using all the water lines. We had to waterjet a solid piece of 1" thick alluminum to make an adapter and then cnc all the ports and taper them from the bigger 26 ports angled down into the 20 ports. All of the water holes fit decently but a few we had to epoxy areas and make it work ourselves. All studs of course had to now be 1inch longer. Amazing how it even misses the fuse box in the factory location. Here are some of the test fitted pictures... not painted yet or anything just media blasted.























So for all of you out there wondering if it can be done or not, there ya go. As soon as it is completely ready to go i will follow up with video and dyno results on close to stock boost so we can have a look at performance gains the manifold and individual throttle bodies give!

Very Nice Work!

[Yellow4g63]

Good job bro. Thats what I like to see! people trying new things and not acting like a bunch of sheep.

[BrodyGoble]

hmmm... paint it silver and then clear it or chrome it all?

[StricNyne]

i will admit i am HIGHLY impressed, and i am dieing to see the results !!!

[s14-240sx]

Very nice.

[avendi]

This is awesome.I can't wait to see the results.

[Red93coupe]

How much did that machining cost dang!!

[Cracka Matt]

thats freakin awesome. love to see people going their own route, as someone said above. Thats half the fun of the automotive hobby for me, making things myself, as opposed to taking the "off the shelf" road.

Good job man, cant wait to see more of it.

[Bwana]

Very, very nice. I'm impressed.

[Sil240]

Nice!!!

Doesn't Bitz sell those adapter plates???They might be discontinued or something.I haven't seen them in a while.

[Darius]

Woww that must have taken a lot of time and effort. Way to go! Are you going to copy that adapter plate and sell it to the masses? Looks like a few of the runners need better port matching, but other than that it looks solid.

[BrodyGoble]

all the ports line right up perfect, thanks for all the comments guys!

[nizmo zilvia]

I recommend making more of them adapters You could easily make $$$.

I'll buy one for sure.

[ripracer]

Me too, I was looking at buying a gtr mani while back from a shop around me. How much did you pay for the actual manifold

[nizmo zilvia]

I've seen some go as low as $125. So its really worth it. Plus I love having OEM looks so thats why I really want one.

[BrodyGoble]

look on ebay i believe there is a used rb26 manifold and itb's on there for $200. get a list of people together who want them and i'll see how cheap i can mass produce the adapter for haha.

[midnightsliding]

RB25? i want

[l0nestar]

RB25? i want

Ditto.

[240sxHitman]

good job. i had the same idea

[ryan15]

Count me in alos if they are going to be mass produced, dont make them for the 25 guys, they get the greddy manifold, haha

[nizmo zilvia]

Count me in alos if they are going to be mass produced, dont make them for the 25 guys, they get the greddy manifold, haha

yea!

[BrodyGoble]

alright , we'll im going to start a list of people who tentatively want a waterjetted and hand milled adapter plate to fit the rb26 intake manifold and itb's to either the 20 head or the 25 head (different of course)

For the 20:

1. NismoZilvia2. ripracer3. ryan154. Darius?

For the 25:

1.midnightsliding2.L0nestar

Any more interest? The more the better as I am sure i can get a better deal for everyone. As far as sourcing out the manifold plenum and itb's that will be up to you but i believe there is a complete setup on ebay for $200 right now!

Thanks, Brody

[l0nestar]

Brody,Darius has a 25..

[nizmo zilvia]

Sweet!!! I would love to rock a oem intake mani like that with ITB!!!!!

[Darius]

And I already have a Greddy waiting for me to clean up some wiring to install it.

[StricNyne]

if i could score one cheap i would be kinda interested for a rb20 for a future project

[onepuff]

I'm definitely interested.

[ripracer]

I'm definitely interested also.

[BoostFab]

you could make it out of 3/4 plates, it's cheaper than 1"; might even pull it off with 1/2"
