so i have a slightly new plan after calling up some tuners and having a chat,

going to run a haltech instead of microtech swap out the manual boost control for an electronic duel stage get the new mafless tune and just got for a single 044 intank fuel pump because i dont really need the full fuel set up for a streeter,

now just need to save the pennies!

figured out one of my AFM's is acting up and thats whats messing with the tune so im just geting another pair to wack in and get the car running mint again for the mean time while i save,

also noticed a bit of oil in the intake piping is there a reason to worry? previously had a catch can set up but removed it

soo has anyone had their wiper washer bottle keep draining in less then a hour and not leak out of the bottle at all, im 99% sure theres no leaks out of the bottle pulled it out and tested it and put it back in and filled it up and can watch the water go down but not not a drop in the engine bay under the reservoir ?? so must have a leak in the line right? but i cant see any drops of water come out under the car so not sure if its worth getting too deep looking for it haha.

i might just do a relocation to the boot like this guy

and run the rear wiper spray to the intercooler with all new lines throughout

so im still chasing this little issue before i take it back for a tune, got some second hand AFMs cleaned them and put them in but still have the same issue, they are a lot closer in volts compared to the last pair so im assuming there good and its something else thats causing the miss when boost comes on around 4k maybe spark plugs?? as coil packs are less then 5000 ks old? will get in there in the next couple of days to have a look in the mean time can anyone think of what else could cause this, also just replaced the TPS

Cant help with the miss, but can offer the following.

When the afms get oily it is because the turbo sucks the blowby out of the cam covers, carrying oil with it. If you follow the breather line from the exhaust cam cover it finishes in the suction side of the rear turbo. There is a restrictor in the hose so the suction isn't too much and no one ever changes it when they put bigger turbos on the car.

The other thing that happens is when oil gets on the afm's they measure high. So you get a rich fuel mixture. What is the afr at 4000 rpm and did it change with the change/cleaning of afm's.

Lastly unless there is oil dripping out of the bovs when you leave the car parked you don't have a problem. Even if it does you may not have a problem.

at 4000 rpm the afms are on 2.0 volts, didnt test what they were on with the old afms because they were reading a difference in voltage even on idle so knew one was bad, and i cleaned these ones before putting them in so dont have a reading from before hand, and now the voltage is much closer only ever out by 0.1 V if that so im assuming these are good, and have never had oil dripping out of the bovs before either,

is there really much point in running a catch can set up or is the factory return set up fine?

just gotta get 1 more afm and am just going to get the issue sorted, swap to z32s and a bigger fuel pump which should get to 400hp which will do for now, but first gotta pay rego in like 2 weeks and im now doing uni so my weekly funds from work have become a lot less so might take a month to get around to everything

yeah just for now because i want to get it running mint so it can at least be driven but will go haltech later once i have the money spare, need to sell one of my other cars

  • 10 months later...

Finally got my car back from my tuner after 7 MONTHS! LMFAO (shouldn't have told him im currently unlicensed and to take his time but on the other hand freed up garage space)

managed to acquire a few parts in this time as well

just put in BC BR Gold coilovers so i finally have some adjustability as well as camber arms all round

swapped out the craft square mirrors for some east bears

finally got some plates to match TKR32 - TommyKaira R32

Apexi exhaust 

R34 GTR Vspec II front seats (yet to go in)

Greddy Front brakes and Greddy 2 peice rotors  (yet to go in)

GFB G-Force II boost controller

Ended up going with a Microtech LT-16cbecause of the price difference and how much easier they are to tune time wise 

Ended up with 400HP at all four which isnt as high as i was after but it is a fairly safe tune with room to tweak with someone who knows GTRs better

Heres some pics with it pretty low and wide since its not getting driven much

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
