gday,

my R33 breaks down as it revs up under load around 4000RPM, sometimes its drive through it other times it wont, at this stage it doesnt seem any worse as the engine gets hotter.

The car has come with a high flowed standard turbo but im not sure what boost it is running yet. Ive read in here that problems like this are common and is normally caused by faulty coil packs or a spark plug gap issue.

my questions would be related to what is better...

Yellow Jacket coil packs or Splitfires coil packs?(i found new RB Splitfires for sale at $575 for the set)

Iridium NGK's or the normal NGK spark plug?

FYI: a not so far away mod will be fitting a GT35 to it and boosting it up, the bottom end already has forgies in it so i would like to give it a good level of boost if the fuel system allows me, so would my decision on spark plugs and coils come back to haunt me if i try and save a dollar now?

are Splitfires the best ones on the market for this engine and a good upgrade to suit the GT35?

is my high flowed standard turbo worth selling once i upgrade? what could it be worth?

thank you in advance,

Gonz.

one of the possible reasons why no one's replied to your topic yet is because all of the questions you've asked have been covered very very often.

have you used the search function yet?

anywho

Yellow Jacket coil packs or Splitfires coil packs?(i found new RB Splitfires for sale at $575 for the set)

Splitfires - i've never heard of yellow jackets before. They'll also be suitable for your GT35 upgrade, but i do not suggest buying them until you run your GT35 and you have ignition problems, in which case it would then be a good time to upgrade to the expensive splitfires.

Iridium NGK's or the normal NGK spark plug?

Normal NGKs gapped to 0.8mm will be fine

is my high flowed standard turbo worth selling once i upgrade? what could it be worth?

If you're in NZ, i'd be interested in buying it . . .

PM me and let me know.

any other questions, use the search function first and THEN make a new topic :P

hope this helps

yeh man i did search and ive read heaps but i still didnt really find the answers, however i did find that there is a common problem with the standard coils and that covering them in tape may help or prolong its life, i also found that i should set my plug gap before spending money on coils but i didnt really find an answer on what plug is best and why, but i will be doing this first thing once im back home!

my fuel system is standard and im yet to see what computer it has, i bought this car from my sister in law, she is only telling me what she remembered the car having when she purchased it over 2 years ago, so im yet to check it out to see exactly what i have, i got the car 2 days before i left for work so i havnt had the time to look into it as im still away, for all i know the fuel system could have been upgraded as this car came with nitrous fitted and she was told the bottom end was rebuild to handle more boost when a bigger turbo was fitted.

Im going to track the old owner down and see if he can shed some light on the mods, ive gotta get a picture of the car up to see if you guys recognise it from a couple of years ago!!

ps: Sorry EliSun, im in Perth over in WA, so i couldnt be any further away from you mate!!

well lucky for me, ive put new plugs in, gapped them at .8, taped them like a thread i found said, got it all back together and took it for a drive, now she revs and pulls clean all the way to 7000RPM, woohoo!! so luckly i can hold off on the coils now, cheering, this is the 1st time its ran good since i got it afew weeks ago so im stoked at the power it has, they told me it had 295rwhp, i recon its close, ill be getting it dynoed soon for peice of mind to make sure its running the best it can and to learn more about it all too!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
