Before someone states the ol do a search thing its been covered many a times in this forum,

For starters i have done a search and ive done research and the above etc.

Im currently planning on an upgrade turbo cams gear belt and headgasket(maybe)

I have 12 weeks until i go ahead and upgrade, But firstly ill like to ask the following

Shopping List:

HKS 2835 pro S Turbo A/R .68 or larger .87 i think

Tomei Poncams 256 Duration 8.5 Lift

Adjust. Cam Gear Exhaust Side,

New Timing Belt Stronger one

Nismo 550cc injectors,

Z32 AFM

Headgasket to lower compression slightly saves on engine life :D maybe but what choice should i go with if any for head gasket, so many thicknesses but not so much coverage on this topic, advantages/disadvantages, and im sure as ive seen results of such setups or as of similar setups, but everyones setup usually differs slighty right down to the pod filter they use, im sure i would be happy with the following setup upgrades on my engine with higher power but is it a beneficial upgrade to do the headgasket to maintain engine life via lowering compression, if so which one would be most beneficial for my upgrade, as i wish not to change engine internals just as yet as im sure im not willing to go over 300 rwkw MAX more of a mediocre 250 middle margin sorta thing, maybe higher but we will see.

For starters:

Current Mods,

Upgraded Clutch

Upgraded lsd

coilovers

k&n Pod

3.5 in turbo back

Higher Flowing Cat

hybrid intercooler

apexi pfc

upgraded brakes (will be done prior to upgrade)

Splitfire Coilpacks

hybrid boost controller

Fuel Pump is walbro high flow

Am i taking the right track? Also any recommendations as well as can alter to desire the above according to opinions? And more information on aftermarket headgaskets brands recommendations etc, as this one has as far as the numerous searches i have done has not bee covered very well :S ? As well as i have got a malpassi fuel reg at hand in a box, need a yay or nay for this item to be installed allong with upgrades, along with which A/R should i go the smaller or Larger.

Ive seen results from different angles, but setups vary to and from im after advice and opinions thats the main part please

Cheers Adam

IMO - stock head gasket is fine

Its poor tuning that will kill the motor.

Fuel reg - stock is fine. I wouldnt change it

I didnt on my car 270rwkw :rofl:

250rwkw is a good safe target

You might find the walbro pump isnt upto the job. Mine certainly wasnt :rofl:

But only a dyno tune will tell that story once you see if you have the fuel or not

wont need to adjust the cam gear on exhaust side as most results have shown best results at 0deg adjustment .. but if you have the dyno time to test it out.. go for gold

try a cometic metal gasket... std thickness and cheaper than a nissan oem ..can handle 18psi from a 3040 so you should be right with the 2835 ..

gates belts are meant to be stronger than the factory ones, and are about the same price .

with the 550cc injectors i doubt you would need the FPR either at only around 250rwkw

Ah cheers guys this is helping me out, one to save money two the need to possibly get better fuel pump, probably the bosch 040 intank pump should handle the job, so the cometic 1.0 mm i think is standard head gasket as well, which helps on choice as well

Hmm what will i do with this fse malpassi fuel reg? more space takers in shed

Cheers so far, still open for opinions if others are willing to give if they wish,

Adam

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      R33 GTR running -9 with no tune

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.

      Squeaking clutch/throw out bearing

      Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.

      It ended up being that orientation of the float hub in relation to the clutch disk, when I installed it, I heard a loud click and being stupid, I decided to not take it a part and check it. The hub didn't properly align with the clutch disk and was causing the issue. Definitely an odd one! Dahtone Racing was able to fix me right up, stand up blokes!

      By joshuaho96 · Posted

      Right, but I'm saying on the stock ECU measured airmass from the MAF is no higher than stock. So it's accounting for the higher flow rate iso-manifold pressure. You just have to keep turning down the boost until you're within the stock tune's load scale. If you run off the end there's no telling what will happen. This does mean there's zero benefit to the turbos you're running vs stock, if anything it's just a straight downgrade because the transient response is worse, you don't even get the ECU's boost solenoid helping to pull the wastegate closed during initial spool, and peak power is only whatever the factory map can give you before you hit the R&R corner. On a -9 I would bet that you would have to change out the wastegate spring once you have a real ECU and you're tuning it for real. I'm not saying this is a remotely ideal state of affairs, it's just a way to keep it driveable until you can get a proper tune done.
