Hi,

I was wondering if i put a STANDARD RB25 muffer on my *HOT UP* 1.3lt Starlet turbo, would that consider as an upgrade since a standard 2.5lt turbo still by theory flow more than enough for a 2.5inches aftermarket system on a 1.3lt turbo anyway?

Only reason is i've got a 5zigen cannon on it at the moment and its really anoying.

Cheers

just get a proper 2.5" system made up...saves you time and hassle...a 2.5" system on a starlet turbo is about right...i've even seen good results from a 2.25" system...

Mate,

I've got a system, its just the cannon on it that anoy the crap out of me and i'm ain't going to spend $$$ on another aftermarket muffer so i was thinking even standard RB25 muffler should DO THE TRICK.

I had a TX3 turbo ,4wd. Had a big system put on it but the droning noisy was giving me a headache. I tried everthing but couldn't fix it. Went to an exhaust place near me run by an older guy. The problem is with these smaller engines at normal cruising speed is the exhaust gas doesn't fill the muffler so you get this surging and resonance. He had up a mute, really just a washer that fitted in the tip to back choke the muffler and keep it full.

worked wonders, got rid of the droning and since it is so far from the engine it doesn't cause restriction probs.

    • You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!
    • http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.
    • 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).
