hi all

i get this strange "choking/fluttering" feeling between approx 4500 and 6000rpm with my rb25det.

under and over this range the car feels strong as normal.

at 6000, it comes good again with a noticable increase in power.

First i thought it might just be the factory boost solenoid doing its thing because of the change at 6000 but now thats been disconnected - no change.

happens at standard and slightly raised (9psi) boost. same deal.

only mods are 3" cat back exhaust.

standard ecu/afm etc

i recently changed plugs to NGK PFR6A-11 ones re-gapped to 0.70mm

could this be my problem, too small a gap?

help! :)

is it manual tranny? my NA R33 does that too when i slip into the 3rd or 4th with lightning speed, the engine flutters abit then off it goes. i was wondering if it had anything to do with the gearbox because it doesnt happen in any other gearbox. i guess it could also be me dropping the clutch with no accel. resulting in a bouncy effect. Its more annoying then worrying

      I like they don't raise their hands into the air when they shift their sequential boxes, seems to be a thing here in Australia lol...

      I'm not normally one for posting random videos, but I thought we'd all appreciate the honesty about how broken our cars tend to be lol. Genuine skyline life here.

      New CAS just turned up from NZ Wiring. Looks like a nice bit of gear.  So, yeah. Triggered, bro. Realised I may as well do the cam belt while mucking about with it so will order one of them.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
