Hi all, ive tried searching round for some answers but havent been able to find. The thing is my R33 gtst is going in for a tune and i dont know if i should hold off until i buy a Z32afm or if infact this is a waste of money for my car, my mods are: Bosch 040 fuel pump-adj fuel press regulator, fmic,JJR twin split dump pipe, Gizzmo boost controller, HKS pod filter, blits atm blow off (i may have left some stuff out as im in a hurry) I plan to run it on 11psi all the time. My apexi pwr fc is being tuned when the dyno run/tune is done. I was hoping for at least 220rkw at 11psi and a bit higher on 13psi, my question is will i need to upgrade to a Z32 and if i dont will it affect the tune a little/lot? what should i do? could someone please explain to me the advantage of a Z32 and if i really need it/should get it before the tune, Im not really sure if i will go that much further with the mods on this car as its my daily driver (in saying that i may look at bigger inj and hi flo turbo in the future) please help!, cheers

if you are on the stock turbo i doubt you are maxing out the afm, so i don't think you would need the z32. however if you plan to upgrade the turbo down the track then you could just get it when you do that, since it would need to be retuned then anyway.

and you will be pushing it to get 220kw with the stock turbo at 13psi, let alone 11psi.

The standard turbo and injectors are your 2 bottle necks at the moment.

You definately won't need the Z32 until you change turbos so save your $300 until then.

But do get your car tuned as it is.

Power FC with those mods should get you around the 200rwkws, not your 220 unless its a happy dyno.

But if you forget the figure (i got 194) and take it for a spin after the tune, trust me, you'll be grinning from ear to ear :unsure:

I got a Q45 AFM + Apexi Power Intake Kit to suit for sale if you want it >_<

You probably wont need it + the power FC already has the voltage ramp table for the Q45 (select VH41 or something like that) so a tune wont be NEEDED but definately RECOMENDED

I was in the same situation as you and took my chances im now pulling 240rwkw on boostworx dyno with the standard afm obviously not standard turbo but id say you should be fine. How ever shaun did say im pretty much on the limits of the Afm and injectors are on the cards. Let us know how you go.

You can pretty much tune anything on the standard AFM, just that you'll hit the top (20th) cell really early and be stuck with whatever that value is for any load point above, say 70%, so you lose resolution

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      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

      Jacks that fit under GTR lips that can reach the subframe?

      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.
