hi, just wondering if any one can help.

My mates has got a s13 silvia and hes just put a fmic and after a week all of a sudden hes car doesnt run proberly. Theres no power at all. He can plant his foot and it very slowly builds up. Also when cold he car runs perfect again and when its hot and run crap again. also the it doesnt idle proberly and his car rattles so much the exhaust hits the car. I think its the timing could this be it or is there anything else.

maybe the AFM isn't plugged in properly? they would have taken the AFM/airbox off when doing hte plumbing probably

a loose intercooler hose is a likely culprit i think too... its not hard to check to make sure as workshops are human and do make mistakes

let us know how it goes

cheers,

still havent got it fixed. someone said it has to have a breather hose running off you intercooler pipe or if you plug it up you will blow your gasket. can anyone confirm

Thats crap. Most people have a vac line running from there IC piping to the wastegate actuator/bleed valve but you can get away without it.

There is definitely a very small leak somewhere in your IC piping or joiners...pin hole size. If clamps had popped off the car would not go further than 5 meters.

yeh i did. the fmic was install at a shop. so it "should" be install correctly. a week after the fmic install thats when it all started happening. but i will double check.

cheers

haha ive seen some dodgy shops..

but i ahve removed a dump pipe with a crow bar... long story lol..

well sounds heat related

my mates S13 had probs with heat due to FMIC pipping getting hot and mucking with the AFM plug which was sitting on it.. so...

If all else fails grab a hammer and start hitting things.....no dont do that just double check everything and that all vac lines are on and all eletricals connectors are ok

haha.. nothing wrong with some force.. best way of removing items. front bars, head lights etc :P

Thanks heaps for the replies. i will check it out. Also the car does run but very slowly like there is no turbo. but his boost gauge is set to 10psi and he only get 5psi max. No pressure

The breather hose isnt connected yet. he thinks the problem is the hose. it has a bolt in it atm. and thats how he got it. i also said it couldnt be because the car was running fine for a week like it was.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.

      Car Rotisserie

      By Shoota_77 · Posted

      Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!

      Stock rb25det neo questions

      By GTSBoy · Posted

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Rb25det Belts Change

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
