My 26/30 @ 1.6bar on 98 RON goes up to 22 degrees advance if that helps

I'll tell you what everyone will tell you, without a dyno and careful knock monitoring with ign advance it will be hard to tell as every setup will run different.
-
And bam! Cracked (left) vs New (right).. Doesn't look too shabby for a manifold fabricated in Dubai eh?
-
Same dyno, conditions are more or less the same (+ or - a few degrees C) and the manifold is identical to what I had so it should be a good indication in terms of power and response. I still have my datalogs too from my previous runs so I can properly overlay both boost vs rpm to study changes in response.
-
Thank you sir.
I have a chart from 0-0 already that I'm going to use as a reference.
-
Anyone?
So final verdict, If I'm keeping the Type B's with my 6266'd RB30DET, what's a good starting point to dial them in? +2 IN -2 EX?
I'd like to reduce the dyno tuning time

He's copying the replica manifold dimensions that you see in the first pic to avoid fitment issues. He does a lot of manifolds especially on TB48's. Why do you ask?
-
Custom Manifold almost ready

Anyone manage to get their hands on a 6870 yet?

So if I'm stuck with Type B's what do you guys recommend I dial the gears at?
-
Wrong. Bigger ain't better.
All because every other sheep uses them, doesn't mean they are the right cam to use.
Please elaborate Mr Shepherd. They're a good upgrade over stock that's for sure.

Tomei Poncams Type B's!
-
I settled for the Tomei ones and dialed them in at 2 degrees advance on the IN and 2 degrees retard on the EX.Will compare dynos vs stock and decide what to do from there. Re-dialing them in as not as easy as I thought.

Heat Treatments new dragster is v6 based and uses a Motec.
The more advanced Link ecus (such as Link Extreme) can control up to four cams.
With an HR head possibilities are endless. It's just the VHR head (with the VVEL) that is a pain.
But i figured if I was going to open up a VQ and rebuild it and swap the head and transmission might as well do an RB swap, always had the itch for it.
-
The problem with the DE is that it has weak internals as well, the 5AT with a valve body upgrade and TCM tune can be made to handle some power but the engine will also have to be beefed up.
Friendly piece of advice, avoid GTM like the plague. Look up what they've been doing on the370z/myG37 forums. Stillen SC kits unfortunately did not make decent power on the VQ35s.
-
It all looks like it could have been modified to work fairly easily...
You must be pissed the new Haltech Elite can run variable cams and twin DBW yeh?
I ended up selling the 6boost one after a few fabricators told me it's near impossible without major modification to the engine bay and mounts. Maybe my pics don't show it well enough.
I wasn't going to say anything in response to his assertion that no ECU could handle it.
The only ECU Tuning options available to VQ37s today are UpRev and ECUTek (both reflash the stock ECU). Haltech Elite looks like a nice option but has not been fully tested on a VQ37 with Nissan's VVEL. And no I'm not pissed I love my RB
I guess I should've been clearer with my first statement, VQ37 tuning options in Dubai are limited that's what I meant. People in the US have been successful in making good power with UpRev and Boosted VQ37s.
-
You're right, but I don't think they get a lot of RB inquiries from G37's so I had to somewhat wing it. Here's a pic of the manifold sitting in the engine bay. You can see one of the pipes touching the engine mount and the wastegate pipe touching the body. A custom heavy duty one is being built as we speak. Let's see how that one holds up.
-
You should have told 6boost that you were running an RB30/26, they are 38mm taller than a RB26.
I had Sinco Customs (NZ's version of 6boost) custom make me one, and it started with a modified version of their RB26 - T04Z one, and they tacked it together and sent it to me to check fitment before they finished it, it had to go back and forward a couple of times as the RB30/26 with my EFR8374 IWG was a bit of a tight fit, but they did a beautiful job.
6Boost unfortunately has one design (mass production) which is what helps keep the costs down.

Sorry, my only suggestions are;
a) pay a decent fabricator to make one. It is a completely custom fitment you are doing so your chances of getting any off the shelf manifold to fit are essentially random. Give the fabricator both manifolds and say "I want it to look like this one (the cheapo) in terms of layout, but I want it to look like this one (the 6BOOST) in quality.
b) Refit the VQ37 and turbo that. I must say, why the hell did you pull that lovely engine out and fit a 900 year old shitter (by comparison) 30/26? It beggars belief.
I think option a is the best way to go, now I need to find a decent fabricator that will do this and offer a lifetime warranty against cracking.
I switched to RB because:
1) They're bullet proof
2) VQ's are untuneable thanks to the beloved VVEL
3) My VQ37 was mated to a 5speed AT which reduced my life expectancy every time I drove it.
4) I have an RB-fettish haha
Grass is always greener on the otherside I guess
Maybe try using an internally gated EFR turbo so you don't need an external gate manifold ?
That won't solve the problem because the manifold pipes are also touching :'(
-
So I have an RB30/26 swapped into my Left Hand Drive Infiniti G37 aka Skyline 370GT.
When I started the project, I was on a tight budget so I grabbed a cheapo RB26 turbo manifold that I sourced locally:
Had no fitment issues with it, but of course it cracked everytime I pushed it at 1.6bar. So I decided to upgrade to the sexy 6Boost manifold. And what a work of art these are. Had one built and shipped to me to Dubai:
It unfortunately didn't fit in my tight engine bay, the pipes and wastegate outlet sat too low and touched both the body and engine mounts. My mechanic said there's no way to make it fit. So now I'm in the market for a turbo manifold that won't crack and of a similar geometry to the cheap one I have. I'd appreciate any suggestions.
Merry Christmas!

Just what I wanted to hear. Cheers guys.

Is there enough to be gained from Cam Gears to make them worth the hassle on my Tomei poncams? I've read mixed reviews on the gains not being worth the tuning time and risking not tightening them properly when going between degrees on the dyno.
Thoughts?

I have a 6266 on my RB2630 at 1.6bar and it put down 615whp on 98 RON Fuel. What did your GT3582 put down @ 28psi?
If I were in the market for one today I'd probably get a 6466.

Yeah I guess it'd make more sense if people shared ignition maps rather than just numbers
