i need some advice on whats happening to my car. only just bought my r33 maybe just over 2 months now and i've never really fanged it. i did it once and for some reason when i'm boosting it up (almost flooring it), after about 4,500revs there is a surge of power and boosts up more but then it starts to choke/stutter?

today i got my exhaust put in and decided to give it a good fang and the same thing happened. i would boost it up hard and all of a sudden after about 4,500revs there is a kick in the power and it boosts up more but then starts to stutter. as far as i can remember it happened in all gears from 1st to 3rd. i'll test it out tomorow again.

now i just want to know if this sounds like the ordinary stuffed coilpacks problem? or does it sound like something else? fuel pump?

tape your coil packs up and have a go. use good electrical tape. only really need to do it around where they screw into the car. theres a thread about misfiring above 4500rpms,, i used to hav that problem and now it redlines with no problems

thanks for info will try taping the coils not sure how that would fix it but worth a try if it has fixed yours.

vvt switch point, change your plugs first or regap. if it continues to missfire at high rpm then buy some second hand coil packs and switch them in/out until it stops happening (or just buy some splitfires). tape wont work (poor insulator of heat)... possibly better than nothing

the reason it boost harder after 4500 is coz its a standard dual stage boost solenoid they all boost harder after 4500, the stuttering and coffing is coil pack related. also search for a thread that over rides the second boost kick for full boost from go to wo.

^^shit didn't ahve a clue about that. i'm coming from owning 2 32s so have no idea. thanks heaps

someone show me this thread about getting full boost!

As the previous poster mentioned, your car has a two-stage boost controller as a stock item. It regulates that boost will go up to 5psi at around 3000rpm, and then once you reach around 4500rpm upwards, the boost climbs to 7-8psi.

For reference's sake, I've seen mine get to about 7.5-8psi when I get close to redlining in 3rd gear coming onto the highway.

If you were to install a manual boost controller (like a turbosmart, or gfb as examples) this takes the place of the stock boost controller and sets a maximum boost as set by you when adjusting the new controller. Up to around 10psi is considered safe with stock internals and turbo.

Unfortunately I can't help with the misfire problem, but as others have stated have a look on these forums, I have seen a stickied thread relating to it.

Get a turbotech manual boost tee, there on ebay about 40$, They hold boost pretty good. Mine use to hold up to 10-12psi on stock turbo with full exhaust and front mount. Get that and when you connect it, dissconnect your stock boost solenoid.

    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
    • We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
    • This is mine, works a treat for the cars, suction is good, I use the Bissell clean and protect stuff I have found giving it a good spray and light scrub with the soft brush on the head of the nossle for carpet, and a rub with a microfibre for cloth seats and cloth door trims, prior to another quick spray before vacuuming it up works the best @GTSBoy You would surprised on what it gets out of carpet and seats that actually "look" clean, I recommend that you test drive yours when you have a little time to kill, then post pics of the muddy looking water that I believe you will find
