no no, 250kw on stock fuelling is safe, i never said the turbo was safe. and if you're all willing to chip in to buy me a more sensible turbo and/or fuelling upgrades then i'm more than happy to have more power or less lag. and now you're going to say "sell you GT35 and buy a smaller turbo" and i'm going to say "no, because i have work every day and need the car to keep going and don't have the money to get my exhaust changed again. and since its just a cheapie chinese turbo (not a garrett) its not worth diddly squat 2nd hand". hope this solves the (somewhat offtopic) issue of my turbo-to-boost ratio. sadly i have alot of bills piling in at the moment so as long as the cars going, i'm happy. this was merely a thread started to see if it was possible to do this. just to answer an argument. i am in NO WAY intending to remove my AFM as i have solved my issue and all is now right with the world.

i've got that turbo becuase my last turbo let go, and this was the cheapest most reasonable turbo available quickly. and 250kw because i'm still going to be using the stock injectors. like to keep it nice and reliable since its my daily driver

excellent i'll do that then

im not chasing much at all. 250kw i'd be more than happy with. so i'll stick with the AFM. reason it came up, is i just put a GT35 turbo on my car and the AFM is too close to the turbo so has HEAPS of turbulence and runs like ass. so to fix it, instead of shelling out heaps, i'll just get a 90 degree alloy bend and put the AFM on the other side of that instead of just a straight pipe off the front on the turbo.

so thats $400AUD (im in nz) and then a tune ($200 at mates rates) where as i can get a link ecu and get it tuned for that much and it has more functionality than a stock ECU. nice to know it is possible tho

ok cool so it is possible, but an expensive and stupid idea (just get a link/PFC). cheers guys

could i use a SAFC to do it? or does that run off the AFM only?

My flatmate and me are having an argument about this. He is adamant that i can have the stock (but chipped) RB20de ECU thats currently running my RB25det tuned to not use the AFM anymore, and it will run sweet as...... i disagree as i have never seen this done on anything but mitsi's. and if it was this simple, that more people would be doing it (surely). Can anyone shed some light on this?

yeah, i'm getting a retune next week so will up it a bit then.

if i have an adjustable FPR, but stock injectors... can i run more boost by raising the pressure in the fuel rail? only asking as i got the FPR rediculously cheap, but can't afford new injectors atm

it has definately fixed my issue. i have done just under 800kms since i unplugged the o2 sensor and have not experienced it since. i decided to just test, so plugged it back in and with in about 5km's it came back. so i will be replacing my sensor tomorrow and leaving it at that i have also replaced my spark plugs recently with BKR7E plugs and gapped them to 0.8mm. the coil packs are pretty old but seem to be holding up just fine.

** sorry, ignore the BOV part, yours isn't an atmo one **

i'd try cleaning your AFM, and check that ur BOV wasn't leaking.

could you ship to Auckland, NZ? if not, i can get someone to pick it up for me.

thats all i have off hand. mines in a s14 silvia (as im sure you can tell) but its pretty much going out of the T/B then 90 degrees down and through the battery tray. if you want more pics, let me know

have done this and gone for a 15-20 minute drive, and it seems to have fixed the problem!! will running with the o2 sensor unplugged have any adverse effect on either performance, economy or safety? (its not going to blow up when i hit boost)??

My RB25DET S14 silvia has just started doing the exact same thing as described above. i don't know what RPM its at as the tacho reads 133% of what it really is. but it sounds very similar i have replaced the spark plugs and had the ECU re-chipped but the issue still exists. i will clean out my AFM with that electrical cleaner tomorrow, but apart from that i'm stumped aswell (and quite broke )
