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

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!

    • Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!
    • I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).
    • At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself 
    • I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad.
