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 would NOT use one on my car!

grab a justjap stainless bellmouth dump/front in one! and a 3" catco highflow cat from them, those two together were the best money i have spent!

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
