R33 Gts-T Problem While Driving On Freeway

Hey hows it going, i got a R33 GTS-t S2, which is currently tuned on a SAFC i got full exhaust except dump pipe, front mount, apexi afc and pod filter so just the usual mods its currently tuned for 12psi and 98 octane.

Now i recently got it tuned and it feels much better and responsive and ive experienced better fuel economy however, i did have a rough idle which i fixed with a set of spare coil packs lying around and i had some miss fires in the 4-5k rev range which was solved with the change of coil packs.

But i have this problem every time im on the free way cruising at a 100 when i open up the throttle a little it has this sort of hesitation to go and sort of feels like sometimes its loosing power now im not sure what would be the cause of this problem as i have no air leaks or anything and i don't experience it cruising under a 100 or planting it over 100.

But just roughly when staying at a certain rev over 100 or at a 100 and open the throttle up a tiny bit it has that tend of hesitation. Now could this problem be due to the coil packs still or would it be worth while to invest in some split fire coil packs or could this down to another problem.

I got another question what color should the transmission oil be and roughly at how many intervals should you change it.

Yours Truly,

Nick

By transmission im guessing u mean automatic. It should be red. Or still have a red tinge to it. If it smells burnt and is getting dark or black then u might have issues.

Servicing shoukd be done every 60000 or when required by condition of fluid.

The freeway issue sounds like a small problem with the tune.

Try it in a lower gear. Sit in 3rd at 3000rpm or what ever ur car sits at on the freeway. And see if it happens.

Might be rpm related

      I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.

      I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended

      I definitely agree with you there - I never click on content for cars I would never ever be able to get or compete with/against/be seen next to. Seeing a MX5 compete with a FD RX7 will make people upset though, for sure. Even in 2.5L Turbo form which is pretty grass roots. (or at least as grass roots as classic cars can be) Yes we're all classic car owners now.

      Wonder what the cause is, but here's hoping it's nothing too serious.
