atm have greddy plenum, S15 inj, R34 turbo using RB20 act (they run 10psi std), nismo fuel pump & pressure reg......... have PFC, EBC, Z32 afm to go on soon as soon as i can work out if a decent cam upgrade is available with proven increase in power.

Car has been converted to Man trans too.

yea, my bro and i bought a S2 half cut, he wanted the motor and wiring i wanted the conv kit. I changed bell housing too to R33 so i could use push type clutch rather the pull type. Only thing it didn't come with was handbreak and console which a mate who is an jap part importer over here in WA sourced for me brand new from nissan japan so she if 100% genuine. Am using S2 dash too so i dont have A/T lights and icon either. have all the console part numbers too if anyone requires them.

I just have (33 gtst cams) but can't compare because I changed other things as well. While we haven't had the cams degreed, my tuner and I reckon the stagea has milder cams than the 33 gtst - stageas always make less power on the dyno with the same mods.

haha no co-incidence here then, Mark is doing my stagea at the moment - hopefully you saw it there with no motor in :P

the stagea comes up a good 30kw lower than an equivalent gtst time after time. and standard gtst cams are worth basically nothing. I reckon someone with standard cams could test back to back with gtst ones even easier than getting a set measured up

wish i could say i did but im in WA so the phone is the closest i get to his workshop. Mark is great though really knows his stuff and is always happy to share his knowledge. I got my PFC back today so will be getting it tuned in a couple of weeks :P

what CAS is he using as mine is a S1 (R33 series motor) but runs a R34 series CAS (plastic cover) which has a different drive on it? also 33 use hydraulic and 34 use solid cams so which ever way i go i need to put 33 CAS on car.

Duncan did ou change to R33 CAS when ou put the GTST cams in it?

good question - its all going together now. I've got the 34 CAS too, so I think he will use the 34 head to save stuffing around rewiring the CAS.

Do all stageas run the 34 CAS, I thought it might be another "special" bit that the late S1 cars like mine got.

I run Tomei 256/256 poncams, with 8.8mm Tomei springs, and an adjustable cam gear pulley wheel.

Tomei have the poncams to suit depending on the year/month build of your engine.

Tune is happening right now, new GT30 bbiw turbo, p/up tomorrow morning well into the mid-200's I hope

yea metal CAS is R33 series, so to do cam upgrade on S1 with R33 series engine (non neo) with plastic R34 CAS you will need to change to R33 METAL CAS as drive on end of CAS is differnent, I have been told the wiring is different on them so you will need to speak to a mech or good tuner for more details.

PS nice cam cover Tangles

Brendan have you had the tune? What's the latest on the AWKW front? Please tell me its over 230 as i am hoping to acheive that without the port and polish and poncams!

    • 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
    • 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.
