Installed a dual stage boost controller (turbosmart)c On my RB20 Now the car sounds like it's not runnng on all cyclinders, or has a bad boost leak.. then stalls. This is just at ide, the way i have it set up is. the hose flowing from intercooler nipple to wastegate (obviously with the bleede valve in the middle. arrow pointing towards the wategate. I plugged up the nipple on the comp housing with a screw.. anyway. so i hooked it back up to the comp housing ranther than the intercooler pipe and still the same..

--IT WAS THE INTAKE PIPE THAT CONNECTS TO COMPRESSOR, HAD CAME OFF A BIT--

thanks for the help, kept me looking.

Hmm, i returned it to facrtory and still the same. Somtimes, i wish it could just be simple.. and work. It worked on my 33 fine. Still die's at idle, and runs rough as. I took the plug to the AFM off when i put the boost controller on so i thought t could be that, but it's on there good...

So nobody has any idea? it's back to stock, checked all the hoses and wires.. all fine, the only thing i can think of. I drilled and tapped a hole in the crossover pipe, maybe a bit of shit got into the motor. (alloy shavings) but could this effect anything? It's running rough, hardley idles and smells like its running rich.

Are you certain that none of the cooler pipes have blown off?

LOL, f*kn weird isnt it? im a verry DIY person but this has got me stuffed.. i took it for a trash 1hr before i hooked up the boost controller and it ran fine, then put it on.. ran like shit.. chucked it back to standerd.. still shit! changed the AFM.. still shit... i dnt know! all intercooler pipes are fine. on another note, i'm pretty sure the 20 doesnt have a boost soinoid like the 25, cause the hose runs straight from the vacume nipple on the comp housing to the wastegate actuator.

i dont like the sound of this

was the pipe off the motor when you drillied into it?

I'd be checking the plugs and checking to see if maybe one of the tips has been damaged by some alloy debris.

that would be the first thing i'd do. if some alloy has worked ints way into the cyclinder i'd look for that before you try to fire it up again. that corss over pipe has a thick sidewall so there would be a few shavings flaoting around.

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
