i have a friend who wants to order a screamer pipe of ebay for his r33.. at the moment he has a 3 inch dump pipe and the screamer/dump pipe his interested in is a 2.5inch dump.. what his question is would there be any probs/modifications in fitting the screamer/dump pipe where the old 3 inch used to sit.. and would he lose any power since its half a inch smaller.. he is running a gcg highflow turbo...

cheers

He should be alright with the smaller diameter piping because before the dump pipe was a bit bigger to compensate for the wastegate gasses going back into the exhaust.

He realises tho he could get a big fine if hes caught using one :)

at the moment in queensland it's about $5000 dollar fine and vehicle ordered off road until returned to stock. some people have said they got fined $10,000 but i work in the exhaust industry and seen all the new laws and yeah it's round the $5000 mark if cop wants to get you for it otherwise it's an off the road defect

I think its more like a 7000 dollar fine.. and a 2,500 dollar hooning fine.

you get the fines combined.

so maybe its 5000 dollar fine for emissions, 2,500 for hooning and another 2,500 made up in smaller laws broken.

    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2  
    • Thank you so much for the help
    • Yes it is ATF. I quote @Duncan "it takes a good synthentic auto trans fluid like Castrol Transmax Z" It's not a diff. It's a transfer case. Totally different thing. Yes, fluid will come out the sender hole. No you do not really need to drain it. Just pull the old, quickly poke the new, clean up and top up. But realistically, you should probably take the opportunity to change it anyway.
