Hey all.

My car (R32gtst) has been blowing some sort of carbon out of the exhaust for a while, i think its oil (when its under boost). After a base map tune, fuel pump and boost controller i am starting to wonder whether it might be the piston rings go?

Also, since installing the fuel pump (bosch 040) and boost controller the revs appear to be surging during idle. Between about 500 and 1200rpm. any ideas what this could be?

Fuel reg is stock.

Any advice or help would be much appreciated.

Thanks

hi,,could be the rings but like many turbo cars it is almost normal, or check your intake pipe as well as if it has a like a oil blow back(oil in pipe) it could be a sign of needing a rebuild as my old r32 was..probly no good info for ya but hope it helps

turbo oil seal failure possibly, and have you looked at the auxiliary air control valve in regards to the idling may need to be cleaned?

Forgot to mention it only surges when the engine is warm. The aux air control valve is for when the engines cold isnt it?

First off have a mate follow you and put your boot in it.

Blueish smoke - oil

black - unburnt fuel

Then go from there!

Cause ya don't want to start pulling down the motor or replacing the turbo then realizing it was just running rich on boost, or something =)

I am only new to performance side of things, but i am a apprentice mechanic wanting to fill his brain with all the info he can get.

      Tein Circuit Master- rebuild worth it?

      By MBS206 · Posted

      If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.

      Best place to order Authetic R32 Parts in Japan

      Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)

      Murphy strikes again! Nothing at all would have gone wrong if you had the tool kit in the car! You'd have just found the clamp loose the next time you went to touch it...

      Blue slip

      By MBS206 · Posted

      I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...

      Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
