has anyone tried doing this with an AFM? I'd like to do the same but in the cooler piping instead of the intake.

That is actually quite common. Ive read about it in the past. People with cracked AFM housings normally extract the housing components and fit them into metal pipes for strength and looks. I guess it wouldn't give any performance gain but if your housing is cracked/damaged it would be a great option rather than buying a new AFM. Also a small hole in a intercooler pipe is easier to patch up rather than a piece cut out. I was considering this approach if I do decide to run my AFM in the cooler pipe, just not confident on how resilient the Z32 parts are to vibration and knock from the tools. Wouldn't be hard to seal it imo. My brother has this black stuff in a tube which sticks literally everything automotive.

What setup are you planning to run Sarge?

Im going highmount with the stock plenum so im thinking about getting a pipe like on Roy's car made up.

The issue is where would be the best place to place the AFM considering the wiring and also I think the pipe will have to be 3" to make that AFM in pipe mod possible so ill probably need a reducer at the radiator join or do the entire cold side in 3".....

I guess high mount makes it a little more challenging if you're running the cooler piping in the standard location, unlike the image you posted. You also need to consider the wiring because the turbo will be way too close to the wires and the heat wont be good. A low mount setup, the wires will reach as I did do a trial fitment in my old car. I needed 2 3" to 2.5" reducers to sit the AFM between my piping. Really stupid move to upgrade the size of the whole pipe system without upgrading the throttle body to a larger unit.

I'm going with AFM infront of turbo with metal intake pipe! I would have loved a MAP setup but I am not going to hunt down another ECU.

Standard position with a z32afm, pod adapter one end and stock standard turbo inlet pipe on other end but with that reinforcement ring in it (to stop it sucking shut...which some people claims don't work).

z32 afm in the cooler pipe.

always been happy with gtr bov, but it leaks on idle (found out when we installed it in the position of the turbosmart one) and because it was located too close to the afm it was causing problems,

so we had to get something we could tighten extra hard with no leak on idle - so had to get the turbosmart - but didn't want anything wanky so it is part of the stealth range, can't hear it at all... but thats due to the screamer :devil:

Downside is obviously this looks far from stock... upside is I have no issue of revs dropping when u get on boost and then clutch in and the car nearly stalls... another upside - if cooler pipe pops off before the afm I can still drive the car fine off boost.

meh, I run map sensor with a motec ecu in one GTR. the other GTR runs twin AFMs with trust hard pipe kit, the silvia runs Z32 AFM on a alluminium intake pipe to the turbo. all set-ups work fine. I honestly don't really have a prefference for one or the other, but I will say most tuners seem to be able to more consistently get better results with AFMs. I've seen so many map sensor cars running poorly it's not funny.

      RB20DE NEO smallbox clutch.

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      By MBS206 · Posted

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
