Make up an 80mm plug to put where the afm sits, on the corrugated rubber pipe off the airbox. Stick a compressor fitting on the plug and try to put 10-20psi into the intake. This will show up any leaks and you will find them fairly quickly.

E85 can only help, at least you would pass the emissions test.

Sounds like you have the NC and NO mixed up, try swapping the fitting into the other hole if it has one. You have an external gate, why don't you just swap in a heavier spring? No need for an electronic controller really...

We went through about 20 cans of degreaser/carb cleaner, as well as 4 odd litres of concentrated liquid degreaser. Damn those DD engines are dirty inside. Glad the det's don't have egr recirculation. Hands were almost eaten away by the degreasers, just a normal day for me. lol.

I have some here if you need them Kris. Can you get a pic of the seals you need?

Yes, I make them amongst other parts, mainly M35 though.

I can guarantee you it does expand, nothing would stop it doing so. Having the washers there isolates some of the force on the nuts, keeping them in place most of the time. If you tried to use just the nuts you might have problems...

040's are a shit design, do a search around, they are very common pumps to block up, as the mesh is so fine. I wouldn't rule it out just yet...

No idea, mine is sitting here in the box still. The Greddy doesn't show the fault codes properly. I would say, if you want to clear fault codes, you should buy a consult 3.

You sold kids?

It's pretty cheap for what it is imo. Nothing much else works on the 2.5's. There is always the Greddy Touch, but I guess $330 is way out of your price range. Bloody good value for 50 possible gauge readings...

Of course, there is absolutely no expansion, and washers have 100% holding capability. Fark engineers are hard to deal with sometimes. As Badgaz said, the holes are slotted for a reason.

Ahh, the flow never stops, it just forces it through the turbo if the wastegate is closed, or the gate can't flow enough. Imagine a spray gun, force air over a tube opening at 90 degrees and it will suck the paint up into the airflow, the opposite you would expect. Same thing would happen in a poorly designed manifold if there was no pressure helping, the gate would almost flow backwards.

Good bunch of blokes down there, I buy all my injectors from them. I should have an injector test jig set up and running soon, I am setting it up for testing larger injectors as their test jig can only do 1x 2000cc injector at a time. Anyone have a large volume fuel reg handy they want to sell cheap? That is all I need other than the lines... The 2000hp fuel pump arrived last week so I am ready to make the jig once I get a reg.

Exhaust flow at that speed seems to act very similar to water flow from my testing.

That is exactly what happens, and why you need large thick washers under the nuts. I wonder why the manifold studs are always snapping... Clamp the manifold down to tight and it will transfer the stress into the manifold, good chance it will crack not long after, unless the stud lets go first. I would be torquing them down to manufacturers specs with oem gaskets, I am sure Nissan did a fair amount of r+d on the subject.

Was it a GT35 Simon? What happened to it? I have had brand new Precisions fail on customer cars, even before the tune, every manufacturer can have occasional problems I guess. Just seems those GT35 cores with plastic cage bearings aren't the best for hard work. No issues with any of the GTX's I have fitted, and mine has copped a hiding.

I would hazard a guess and say no. Mainly as I have yet to see a reader work outside of Japanese ones. Just get the HKS OB-link and a Samsung, the car is not hipster enough to talk with an Apple phone.

^ This. Those adapters do not provide a good flowing wastegate path, but they should work fine at controlling manifold pressures. A well designed wastegate path adds much more than good boost control, I know this from experience... Just sayn...

With a big enough turbo you should see 450wkw through the stock manifold, but it will become a restriction at much less. You should be fine with 340kw on the right setup. Obviously the better flow from a good aftermarket manifold helps with the top end, but larger runner manifolds also take longer to build pressure, causing the turbo to be slightly less responsive down low. They are also illegal so I only like changing to them on track cars, otherwise there is a good chance you will get defected the minute the bonnet is popped. Just remember, the manifold grows considerably in length as the exhaust temp rises. I imagine the ports would line up fairly well when the manifold is cherry red, as it could be around 10mm longer than it was. The water cooled alloy head wouldn't expand anywhere near as much.

Billet SS2, the big one.

PM'd.

The twin Nismo is 70mm internal to the muffler, where as the Fujitsubo has twin 70mm in the rear muffler. Theoretically the Nismo should be quieter then. I wonder how much it will restrict flow...

A shift kit should see it to 250kw fairly easily... Then again, the clutches are probably 20 years old.

Why? If he is worried about knock, shoving e85 in the tank will fix that... I have seen 250kw easily on petrol safely, and over 300kw on my Ethanol Emanage Ultimate tunes. I can't see why the VQ would be any different to RB tuning...
