You can get a twin scroll setup with a T4. That's what I plan on getting. I have only seen a pic of one on an RB26 on the internet though. WG placement is on the shock tower side of the twin collector, so two tubes come off and join as they head towards the firewall. The WG would run parallel with and on top of the frame rail.

eh? - I suppose we could break it up into two group buys, but I'd rather just hash it out ahead of time and ship once. I really need to get an international calling card and just talk to the guy. There's too many things to cover in e-mail alone

wawazat - I don't know whether your post meant in or not?

I'm still waiting on a response from Kyle from the original response.

Someone over there is going to make a couple extra bucks!

Do you know if they have a LHD over there or if its going to clear? It'll be better for him to rotate the back of the flange so the downpipe doesnt go straight to the steering column like the other threads pic.

i copied some pics out of calaisturbo and put them in my photobucket.

Here's the RB25 manifold w/split inlet.

That looks awesome. You got any zoomed out? I'm trying to avoid hitting my strut bar.

i would still like to see some pics of it clearing the steering column before i spend 100ish of my hard earned-poor-collegestudent dollars



other than that, this looks awesome.

from the last pic i see a distru and we don't have one there so i see no reason that he can't make the turbo sit forward more since these are custom mani's . so that should take care of the dp and wastegate issue imo.

For you and your strut bar nizmo



Definitely not in an S-chassis though.

Why is everybody so concerned with this manifold hitting the steering shaft? It's the downpipe that hits the shaft, not the manifold. I guess it's possible, but I'm not too worried about it.

We're all gonna have to make custom 3" downpipes anyway, just fab it so it clears the steering shaft.

BTW here is the distance from the head/flange to the steering shaft.

If you could let him know I would greatly appreciate it. Plus I think it'll be better overall since we'll have more to play with our downpipe and not worry about hitting the steering column. Its going to be a tight fit otherwise.

Wow that looks good. The only problem I see is that we are going to use this in our S-chassis and it might be different compared to that. We'll see though.

I know where your coming from but its cyl. 6 is what Im concerned. It just might hit the steering column, not the downpipe.

I might be interested....let me think about it some more, not sure if I want to spend the money on a manifold or some other things. If not this batch, then next (if there is a next).

I'd also like for it to sit as far forward as possible. I need the turbo to sit in front of the first two cylinders, instead of in the middle of the motor, as the strut tower on my Z car will interfere if I tried to use that config....

I hope hes making them right now, haha. How long would we have to wait? at least 2 weeks until they are all done?

I just got an e-mail from Kyle and he said that the manifolds will clear the steering shaft 100 percent. He also sent some pics but I am on my cell right now and will post them later tonight...if I am not too sloshed ;D. jk I promise.

Ok ladies. Here are some more pictures of the manifolds for the RB25/26. As you can see, the manifold is pretty tight against the block.

Side view of the divided collectorCollector shot

To be honest, I want what is shown in the second picture with a v-band wastegate flange welded onto it, but I'm hoping that comes with the manifold. Some fabrication will be necessary to either get your dump tube welded to your exhaust or get a dump tube fabricated to vent to atmosphere beneath the car.

They are nice looking mild steel manifolds. The top one looks to be undivided, and the second one is a true divided....

I'd prolly want to configure my own w/g tube placement.

Keep the updates flowing Darius

Judging by the first two pics, It looks like there will be issues with the w/g placement and the master cylinder.

Placing the w/g aft (if it fits) makes down pipe fabrication very tight. I'd def want that turbo placed as far foward as possible. But i know it will be difficult for 6boost to do.

Im hoping the turbo would sit up forward aswell so that we'll have more room to place with and not worry about our wastegate hitting our frame.

truth. when the downpipe is pretty much hugging the block parallel and dropping between the column and the block, there really isn't much room for the wastegate without interfering with the downpipe or the master cylinder.

my wastegate dump drops in between the steering column and the frame

I'm not worried so much about the piping from the WG to the downpipe because there is jack shyte for room in there and will probably have to be run like yours anyways. No biggy, just some extra fab work. I just want the turbo to fit relative to the valve cover, the wastegate to fit relative to the strut tower and master cylinder, and leave the rest up to piping fabrication. And if a flanged connection has to be added in the dump tube to be able to remove the dp, that is okay with me too.

I'm hoping a big single will fit using their manifold, considering where my shock tower is....
