damit, last time i asked that question to somone, they said, you shouldnt do it because you should need some restriction in your exhaust, but im running 12 pound and at about 4-5 thou, it flattens off, now im not the most knowledgable in the art of turbos, but could the standard dump pipe be whats holding it back and making it flatten off?

Def get a dump pipe.. pref bellmouth - have a look under the traders section.

Just a word tho - You might get some boost creep. I used to get bad creep, but that could partially be because i dont have any pussies in my exhaust. Fixed with an ebc and pulls 10times harder then with the stock solenoid or the turbosmart boost tap

^^ boost creep happens with poorly made split dump pipes, the wastegate flap fouls on the separator on the dump. Hence your boost goes UP with RPM.

You can't fix boost creep with an EBC, if your wastegate will only half open then boost will go up no matter what the EBC does. You're describing something else, like boost spiking caused by a shitty bleed valve (you set it to 10psi and it spikes to 12psi before settling down to 10).

does anyone know where you can get 3 inch dump pipes for an r33? also, is it worth installing on a 12 psi stock turbo with a 3 inch exhaust? cheers

Recommended upgrade.

www.justjap.com sell JJR 3" stainless steel bellmouth dump/front pipe for $199. Do you have a 3" high flow catayltic converter as well?? ...or no cat will do. :D

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
