Hello my car is a R33 series 1

T2871r

Frontmount

full exhaust

Safc I

Profec B EBC (turned off untill tune) boost spikes to about 12psi

Stock ecu, injectors and afm

i recently replaced the coils which fixed my missfire. The other day i was driving it and under full load on boost felt like it started to do it again. Except this time it would fully stop for a split second then go again, then stop, and go again. Happens at higher revs and when my foot is to the boards. Car is untuned getting a 040 soon then will get it tuned. i have heard of fuel cuts on these maybe thats it??

Any ideas

cheers

Firstly that link didnt work, and im not running big boost, nor is the turbo that much bigger than my stock one. I undersatnd that its those things however i know people making heaps more power than mine on the same stock set up. I need to know wat is actually causing this to happen. I dont just want to throw parts at it.

there is no boost cut

Its a flow cut, the more air, the more damage can be caused, so the ECU protects the engine.

You have a factory ECU and AFM which are guaranteed to be the problem.

If that link didn;t work, then at the top right hand corner, there is a button called "search", I suggest you use it because this problem is covered about once a day.

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.

      Don't do what I did, use a 300000km old housing with billet gears. The old pump probably was clearanced with saw dust, Edward Lee's special engine treatment sauce and a good odo wind back. I had oil pressure issues, then replaces pump with new housing, new billet gears and 2x track day later binned a motor due to other oil related issues due to a previous engine builder. Long story short, buy a M2 or 3 or 4 N55/S55/S58 and enjoy life.

      Yeah. "New pump" does not have to mean "massive pump".

      Well, can you still get an OEM pump, and by the time you're buying a Nismo/N1 etc, just buy another aftermarket pump. It's better to have the pump able to flow more if its needed, than for your pressure to drop off. At any point in time, you're replacing the oil pump in a rebuild. Aftermarket pumps are likely going to be a better economical choice, and they don't have any negatives, even if they can flow more.   Also, when you're saying "replace the pump gears" are you meaning leave a 25+ year old housing in the engine with unknown wear, and just put new gears in? As that sounds silly to me, especially if you do have that minute amount of wear, that means your new pump gears now have a little bit more clearance beside them, which means, whelp, you may not get to build a lot of oil pressure or make a lot of flow.

      Right, but if you replace the pump gears + put a spline or sine drive gear on the crank on a Nismo/OEM/N1/etc pump at that point do you really still want more flow/oil pressure? Let's say this is a the aforementioned "keep it simple" build, no more than ~400 kW at the crank.
