Hi guys,

I'm in the middle of deciding how to upgrade my gtst's performance, and number of options have come up over the last few months...currently i am chasing a fmic before anything else happens, but after that, i dunno wut i could do to the car and would like a few ideas.

right now the car has a hi-flowed T03/T04 hybrid turbo, complete turbo back exhaust, pod filter, stock cooler, S-AFC, EVC 3 boost controller.

It managed to make 200rwkw at 15psi of boost after tuning the S-AFC (comes to abt 270rwhp).

Could anyone gimme an idea of wut sort of power this car could make once a fmic is installed? The car would probably be running at 10psi most of the time, or maybe even stock...I just want to know wut sorta power I would be making. If it feels sufficient, I may call it quits as far as performance goes, and concentrate on the suspension and brakes like a good boy.

Hypothetically, a budget of around 4k-5k would be do-able after the fmic is installed...would take a while, but do-able...would like to know wut could be done with this money.

I have more in-depth questions, but will post them once opinions have been made regarding these questions first.

Please feel free to talk at length, then everyone can benefit from the know-how

thanks,

Zak

Hi Nrage33, I would suggest a GTR fuel pump as the next mod as you are getting close to the limit of the GTST fuel pump. Then a standard R32/33 GTR intercooler (good up to 300 rwkw) usually gives a 20 rwkw increase over a standard R32/33 GTST intercooler. I would then suggest an adjustable exhaust camshaft pulley. That should give you 230 to 240 rwkw which is pretty close to what the standard internals will handle.

Hope that helps

sydneykid,

thanks for the info...what does an adjustable exhaust camshaft pulley do anyway?

I'll definitely look into the fuel pump tho, I can feel these current fuel pumps I have are near their end...

If i wanted to reinforce the internals, what exactly would I need to do?

2.5 lit should be fine depends on how much power you are after..and if you are going over 240rwkw then probably some mild internal work...but after that you can push it even more depeneds on how much money it comes too in the end...remember tuning and dyno time as an extra cost..

This is what happens when you are making 240rwkw with an RB25 and then slap a RB30E bottom end in there.

Due to the head flow charastics the final power is still roughly the same.

I guess the saying still applies.

There's no replacement for displacement. :burnout:

      Requirements for Xenon Headlights? (Possible Solution)

      By rahilp · Posted

      Hi There I went through a rabbit hole of reading about Xenon headlights and the ADR regulations for having them installed. As people have been defected by running factory xenon I was researching in ways to make them compliant. Everyone always say needs to be self leveling and have washer installed, which I don't necessarily agree with. For this argument I'm using R34 as reference as I'm more aware on the construction of the headlight compared to the R33 Xenon, which may still be the exact same case.   For the self leveling clause taken from ADR 13 - Installation of Lighting and Light Signalling Devices on other than L-Group Vehicles As you can see the bold text "these manually adjustable devices from driver seats" are fine to use. As Series 1 Xenon model headlights do have a 4 level adjuster on the right near the ignition (however not series 2) then these model are consider compliant in that argument.   For the Self Cleaning aspect of this argument clause taken from ADR 13 - Installation of Lighting and Light Signalling Devices on other than L-Group Vehicles Now i can understand the argument that Xenon will need a washer as they are over 2000 lumens, but I clicked on the 12 at the end of that sentence and it takes me to the end notes which states R34 for headlight lenses are plastic, not sure if PL is mark as I don't currently have my skyline to confirm that marking is there. But could you not technically get a lenses with the PL marking on it and then get away with the argument that you need a washer. I went through a quick read of the adr and might have missed something else that may cause them to be non-complaint.    But wouldn't these technically be complaint headlights   Would love to hear other people input on this and shed some light   Edit In regard to the the washer portion I might be mistaken ADR 45 (which I believe is Regulation NO.45) states 12 cd (candela) I dont understand that portion in regarding to calculating the candela if anyone can shed some light. Otherwise I guess throw in a washer for the headlight and you definitely comply.

      I'd say closer to OG GTX3582R, just smaller trim - so 59mm inducer/82mm exducer as opposed to 62/82 for the first gen GTX3582R. Yeah EFRs were boss, the EFR8474 is still an absolute beast and it perplexes me that people still go to things like Turbosmart/Garrett etc when the results people are getting with those are pretty unremarkable compared to what you could get with a turbo available well before those options came out.  DriftSquid (I think) "upgraded" from an EFR9174 to a Turbosmart turbo and promised a comparison video - and kinda shuffled awkwardly and did a bit of diversion from the fact that they didn't get any improvement going to the currently massively hyped brand of turbo from a turbo that was a bit of a frankenstein that had been well superceded in it's own range before the Turbosmart unit he put on there even came out. I suspect the EFR would outperform most Xonas for what a lot of less-insane RB owners would go for, in the 400-600kw range but the Xonas are looking hard to beat up to maybe in the mid 700kw range at this stage- basically where EFRs don't really reach, and before the Precision turbos take over.  What the Xonas do well in the "EFR range" is be easier to package etc, and work very well if a divided housing doesn't suit your application.
