hey guys, had an accident last week.. got cut off on highway and hit barrier at 110km/h.. got out of it ok.. i think my air flow meter may be screwed.. it idles fine just once you come on boost it starts missing pretty bad.. almost like its actually running on 5 cylnders.. sounds like a wrx.. well a sick one! anyway i got home and let it idle for a few seconds and thought i heard a wierd sound.. so i take off the pod.. and put my ear up to the air flow meter..and sure enough.. i hear a little sound.. sounds like a bell!!!! WTF! like a little bell just ting.. ting.. etc.. is my turbo on its way out.. the car still felt pretty strong before the accident and i have never noticed this sound b4? any one know anything? any help would be great. by the way this is a rb20det.

cheers.

:upurs: nah, its funny because you drive down there pretty much any day and see all these cars that have like hit the side barrier, and its like 5 lanes and so open wide viewing angle the whole way to the GC and everything.. it makes the Monash and Ring roads in melbourne look like narrow roads so i'm not sure people manage it!

Thats some nice whoring.

I'd take it to a profesional for an opinion. Maybe pull the af meter off and havea look to see if anythings loose in there, check wiring hasn't been crushed in the inner guard if the car was an auto before the conversion.

Probably pull the front pipe off and have a look in the turb to see if you can see any chips in the blades and have a feel for play in the shaft. BB turbo should have very little shaft play.

Unless somethings fallen off the af meter then the turbo shouldn't have eaten anything though.

Just take the pipe from the compressed side off and look for "shiny bits" first. May save some work.

remember a turbo spins way quick so if it was interfering anywhere it would sound like a squeal

"interfering...squeal" sounds like gordo and DJ with their 14 yo :)

took everything off bar the turbo and there doesnt seem to be any signs of anything. the turbo wheel spins freely and there is no metal shavings.. there is very little play in the turbo as well.. hmmm.. but i guess when its spinning as fast as it would when i come on boost if there was a tiny bit of play it would get worse????

      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.

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.

      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

      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.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
