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

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      R34 Skyline Sunroof Won't Tilt/Vent

      By GoHashiriya · Posted

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.

      It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣

      R34 Skyline Sunroof Won't Tilt/Vent

      By ShezzDogs · Posted

      Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
