Stao why don't you try make the TD06 work with you .82 type B housing?

with a little machine work you could be adding a whole new product to the market.

The SS1PU is not a GTRs.

2ndly if you are comparing td06 to a GTRs its never been compared on fair grounds. Install your td06 internally gated in a stock rb20det manifold plus all the EGR and road legal crap you would normally expected to run on a stock setup, The TD06 would not perform any where near a GTRs or a SS1PU.

All supporting mods counts, The turbocharger does not take all the credits.

I hear what you are saying. SO many people carry on that the std manifold is good for 300-350rwkws etc, I have long been an advocate for binning exhaust manifold asap...but others are happy to use it and hold back the performance gains available to them...combined with the fact for the same price of the HKS GTRS you can buy a complete TD06 setup. So based on dollars spent it is a fair comparison.

Anyway , interesting to see more billet results

So I received my JJR 3inch dump today.

It appears that the inlet area of the exhaust is smaller than the outlet area of the turbo. in some places about 0.5cm in width and length about 1cm. I'll try and machine as much as I can but doesnt appear to be that much room.

Thoughts? Will it be much of a restriction?

Heres a pic, not the best

It needs a little die grinding by the looks of it, as does the adapter Stao machines up imo.

Can't the machinist at least round the corners a little Stao? Is it a CNC mill?

All the corners in the .82 B rear housing has been rounded off, The flange area can't be any bigger, its been traced through the gasket.

For the Billet TDxx series to work probably there is a need for a proper exhaust manifold, external gate, and a front pipe. I'll get them sorted very soon.

Stao why don't you look into getting a spacer plate made which accommodates your external gate?

that way you can offer the turbos in external format and the user just needs to make a dump pipe, which you can supply a v band ring and clamp for.

Yeah will def be fixing up the dump pipe

Want everything perfect before I fit it all up and dyno it, rather than going to the dyno and finding out all these restrictions

I should imagine that a spacer between the manifold and the turbo that is big enough to have an outlet for the wastegate will start causing problems with pushing the turbo outward/upward/downward enough to make it start hitting other stuff. Certainly on the factory turbo manifold you'll hit the strut tower after only a smallish push outward.

Ive seen one of those ebay spacers with the 2 bolt flange plate used to mount a precision turbo on a skyline before. It certainly can be done, and if Stao makes the spacer himself Im sure he can also make sure it fits well.

Then again he can just supply housings with a gate port

Dimensionally (in/ex) its the same size as the existing 20g, its blade design that changes. Front cover is the trust style .60

if changes have been made to either inducer or exducer I'm sure stao will correct

Updates:

I'm getting some steam pipe bolton manifold and high mount manifold made overseas as I'm typing. I should have a prototype received by mid next week for trailing and testing. Those manifolds will be available for $300 to our customers assume they perform as expected.

It appears a larger turbine setups would perform better on factory manifolds, I will trail a SS2 in a .82a rear housing on current std manifold for some comparison.

how these going stao.?.are you still going ahead with a cheap steampipe bolt on jobbie?

i'm keen for another turbo, probally a ss2 with the steampipe bolt on if it goes ahead, and stick a gate on the exhaust

housing, just waiting to see how it pans out

cheers

Yes I've fitted the prototype manifold. It is awful, lots of dressing up work required and i'm certainly not impressed with the level of workmanship, the final product I will be selling will be a steam pipe manifold with every thing done to specifications. it will definitely flow much better then a stock Rb25det manifold.

I've re-enforced the the joiner, that is where its likely to crack.

I'm pretty sure this is what some people sales on ebay. The bolt pattern on the flanges for cyc 4 5 6 are all out. it won't fit unless dressed up.

Finally fitted:

By the way any one needs their wastegate opened up? we can perform this service for $120.

    • Ok i will get those 310mm. I found one but on a different site. This is the description on those...is it ok? Technical parameters: - Axle: front. - Disc type: ventilated. - Number of holes: 5. - Disc diameter: 310mm. - Total height with center: 54mm. - Thickness (new/min.): 30/28mm. - Designed for brake calipers manufacturer: Sumitomo.
    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
