I can't see why a rb 30 with 300 rwkw wouldn't get 10 litres / 100 km as long as you stay off boost.

Definately something not right with your 200klms/tank economy Mafia.

My untuned pfc easily cleared 500 k's at cruise.

Might be a silly question but is your O2 sensor turned on in the ETC menu?

Unless you drive with your foot flat to the floor something's wrong - last dyno tune we did 160k's on the rollers and my '33 had just under half a tank left.

Hey mafia...

I had a similar turbo combo to you.. I had a rx7 rear wheel in a vg30 rear housing and the max i could get was 220 - 240 rwkw (depending on which dyno)

The guys said that the rear housing was way too small and that they were only good for around 230 rkw....

So you may have to go for a bigger rear housing ???

I since sold my turbo and got a gt3540 =) with .82 rear

Can i suggest a cheap fix, that can narrow down your prob?

Why dont you throw some toluene in the tank and get the tuner to do a quick wot tune. If its the fuel ron causing a low reading you will know straight away.

When hes finished just reload your old maps :D

did the .8 housing make any difference in power and detonation levels?

hey mafia, iv read your WMI closely over the last few weeks.

im actually quite intruiged. i have the SAME car as yours except its stockish :)

full exh and filter putting just over 180rwkw on like 10psi or so. running everything stock inc ecu etc

are you able to post up some pics of the installation please? i had a look at ur old threads but the pics wouldnt load up.

i was planning on getting the Stage 2 Boost Cooler™. so how i understand it is with my setup, i wouldnt expect any power gains? since i wouldnt be altering the boost levels at all(for now).

feel free to email me pics etc if possible [email protected]

      Just one more post to show the final result and the original "janky" solution for a laugh. Everything feels really tight and no wobbling at all, very pleased 🙂

      R32 GTS (RB20DE) clogged cat

      By MBS206 · Posted

      The hot exhaust light will come on not from just the cat being blocked, but it's just a temp sensor, and it's designed to warn you to not do things like park in long grass.   If you've been pushing the motor a bit, it can cause the light to come on.   Second if the cat is rattling, I'd suspect it's not blocked, but instead falling apart inside.   The easiest "fix" until you can get a cat put back in, is to unbolt your one, bash the rest of the insides out, and then bolt it back in.   For a daily driver/street car, I am in agreeance of put a cat in the car. If it were race car I wouldn't care if it were removed.

      No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️
