That is for card AFMs like R35 ones.

And no, you cannot cut up a plastic AFM (ie, Z32) and weld it to metal.

Shit you’re right, they’re not even expensive $253 brand new genuine. Can it actually be done in practice or is it just a theory. I mean with the wiring and all, do you know how to do it?

Oh yeah, how long are you in Sydney for? Also have u got the wide band, intake temp sensor, pigtail etc?

and how many days will it all take you reckon?

maybe we can work something out where I can leave my car with you and u can install everything like turbo, walbro, injectors etc. I still need to v band the dump pipe and get pipe made or the turbo elbow part and a turbo intake pipe made

Well this has escalated quickly lol. While yes I could install all those parts, it would be much quicker  to have a workshop do it. 

If you had the car ready to go, I'd have it road tuned in a day no problem. 

With the wideband and air temp sensor, they'd be permanently installed in the car and need to be there before it's tuned.

Yeh I’ll probably do that all myself , a workshop would charge thousands for that, I thought maybe u can do mates rates.

but that honestly sounds good, have u got the wideband and air temp sensor?

how long are u gonna be in Sydney for?

I have a spare brand new Haltech / GM fast response air temp sensor and connector here if you need it.

The Haltech WB1 wideband is about $400 from memory.

Guys I said f**k it and bought a nistune for $350. The guy I bought it off didn’t have a case for it, I was wondering if any non neo ecu case eg 33 ecu will house the neo motherboard and nistune chip nice and snug. I only ask cause neo ecu‘a usually go for $150+ and r33 ecus are only $50.

also unrelated question: is the oil pan bolt meant to have a rubber washer on it? Cause mine just have a metal washer ‘welded’ on the bolt. And I only ask cause my oil pan seems to have oil residue all over it.

Coz it don't fit. Different mounting points inside, different loom plug opening.

Ah okay. I can drill new holes for the mounting points but is the loom plug opening smaller or bigger than the neo? Cause either way I can grind it to be bigger and it doesn’t matter if the 33 ecu opening is bigger, if it leaves a gap that’s not a problem

If you're going to that much effort (ie, buying an R33 ECU just for a case that you then have to modify), either just fold your own up out of 1.2mm sheet steel/ally or put it in a plastic kitchen storage box.

If it's the same as the RB26 the copper washer is going to be stuck to the bolt pretty well, you want to use a knife or a something to pry it out before replacing it. You're supposed to orient the washer as seen in this diagram for a 370Z: 

Actually the standard OEM sump washer is not a copper washer but an aluminium single use crush washer, that's why it goes one way. Large side goes towards the sump.

If I’m to do that, is it okay for the bolt and nut to be in contact with the ecu? I just don’t want it surging or shorting out. I was thinking u can get those raised plastic cylinder things to act as a spacer between the ecu and the nut and bolt

    • VP race fuel like VP 109 ron unleaded is a waste of money compared to E85. Just go flex fuel setup so you can run on pump unleaded or E85 all without draining tanks or switching tunes. You go VP race fuel you will have to change tune when using it, then change back to a pump unleaded tune. VP109 for example will support about the same boost and timing increaes as E85, but it requires the afr's to be a lot leaner than E85 but richer than pump unleaded.
    • Whats your budget? Maybe call Nispro in QLD for quote - they build a lot of VQ and have a turbo kit in development - but id say at least 20k to do it right - oh actually maybe do LS swap will be cheaper but....hmm  im a purist - so id rather stick to VQ35DE or whats the point lol.... just my opinion - do what u want. its your car  
    • Ok sorry I should rephase my question. But good answer haha.  How can I make 400whp that isn't using nitrous. 
    • dyno run would be on VP race fuel or e85 / e98, E85 is not easily accessible by me. Closest pump is 30 min in a direction I do not travel. So while I will go out to get it. It will also get pump gas 93 octane is highest avilable in US so overall power will be down if mix fuels  e50, e30, e10 ect 
    • Cheapest way? Spray. A wet kit with 200hp jets could be up and running for less then $2000. Then its about $16 per pound when its time to refill your bottle.
