Cat like catconverta? It has no cat it has been removed. VT has been turn off and on with no significant difference

Right now its a odd ball. Because alot of money has been spent on te engine to only make 275kw :D

Yes catalytic Converter. Ah ok no cat....hmmmm. Have you tried seeing if it makes more power when you disconnect the exhaust from where the cat used to be? How bad is the pressure drop over the intercooler?

Cam gears dialed in will be done next. However tuner has asked other tuners advice and they say if car makes 275 on 96 octane at 8psi. It should have no trouble making more power dialed or not. Im pretty sure the dynaPack Dyno is in rear wheel kw. I will have to ask about this?

96 octane... are you from America or similar?

Hub not equal to rwkw. You take the wheels off mate :D

275 on a HUB @ 8psi sounds about right however for a GT35. Anyway, that's not the main issue here!

If the timing is not correct mate, you can have issues making power, most certainly.

Shell and Caltex in NZ is 96 Octane. We have Gull and thats 98 Octane. But is over 1 hours drive away.. We were running up on 96 and then doing a final tune on 98. But never got that far.

definately not the plenum...possibly the plenum install if there is a leak...

how is boost through the pull? does it stay constant or drop off a fair bit?

droping the exhaust for a run is the best idea as is doesn't really cost you anything and can rule out a component.

you'd also want to have the cams dialed in as they are a fairly important part of an engine and can see a range of differing results... which cams have you got?

I have 1 Tomei exhaust cam gear. Im hopeful that changing this will do something. Also the plenum, i removed yesterday and have purchased a new gasket to rule that out. The Exhaust tip is a oem nismo er34 unit and has a restrictor in it. A Small Armour All Spray bottle it to fat to poke up it. I think its 2.25" Diameter. But still pressure test was 2psi so.. Will suggest losining off the exhaust front pipe

Gasket is two weeks off from nissan nz / jp. Some bit of a wait ;/

Im hopeful we will get everything sorted by next time round. Here are a few pictures now taken of the exhaust "3" and what not.

Bit of a over dose with Silicone on the plenum..

I will take care of the silencer pictured by taking it to an engineer to saw off the tip. Remove the silencer. Take out a pcs of the silencer. Pop it back in. Weld the tip back on and after alot of $ will be good as new

Ok um...but what cams do you have. As in what camshafts :rofl: 2.25" is bloody small! I think my exhaust is going to be too small for the 25/30 with a gt35r so 2.25 is pretty small. I know you say the pressure test said 2psi but I still think you should just drop the exhaust and measure the power output. Please :D

Fuel system? Pump? lines? pressure tested @ [given psi]?. What rail you using? are the injectors maxing out? is it IW or Ex?

Not he fuel pump and Injectors. Have a inside fuel guage ( greddy thing ) Tomei pump sard 800 or 850cc injectors. Maybe there Denzo.

Cams are Pon cams. Will see what happens second time round. 2 weeks away :rofl:

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).

      Jacks that fit under GTR lips that can reach the subframe?

      Perhaps the answer is... more jacks!* *proper jacks must be used.

      I NEVER think about using a scissor jack unless there is absolutely no other alternative. f**king things are dangerous, annoying and stupid.
