6Boost mate, Australian made, about 1200bucks, Or ebay china made, 250bucks..... Its your call, sometimes u jag it and ull get a good one, sometimes you'll get a crap one, but so far i no 3 people that have gone down the povo road and had no probs, only on was for a rb26.

My mates 419kw was with a T04Z too, 1.0rear.

if it was me and it was goin on my gtr... to tell you the truth id be goin the 6boost haha even no i said what i said before, for my gtr only the best.

but the 419awkw and its still doing it now for the past 3years dose make a dam good point.

But thats exactly it.

When spend 15k on everything to support the T04Z, and then get a cheap china piece of shit for $350 to "complement" the setup.

A good hard big build requires a decent designed and setup manifold with decent merge collector design and so on IMO.

There would be signifigant gains swapping from a cheap one to a decent purpose/performance designed one at power levels over 400rwkw etc.

For your average 300rwkw setup, those manifolds probably are not all that bad, but the more performance you require, sometimes you just cant cut corners

Yeah, but how much would he have (and how much more responsive would it be) with a decent one?

From what i have read the problem isnt the flow, its the fact that made out of thinner lesser quality stainless, with high heat and pressure they crack and warp.

TBH we are making 860bhp and shooting for 900bhp+ with a china manifold... who knows how long it's going to last?

However... If you buy one, to make it work/last you usually have to machine the flanges flat, grind the dodgy welding dags out and re-weld some of the joints... If you don't have the gear, it gets expensive.

So you might as well buy a decent manifold to begin with.

My stainless 2mm mani lasted 12 months or 4 track days before it cracked, got a steam pipe one now.

The extra money for a better mani is worth it when you have to replace the crap one every year.

Thicker pipe and coated the gases stay hotter and make the turbs more efficient.

    • 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?
    • 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).
    • 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.
