Done a bit of research but want to know ur thoughts, since getting my 3" turbo back my car has been hesitating when on boost and only sometimes, only happens when the car is warm or on a warm days, plugs replaced and gapped at .8 (bkr7es), stock intercooler, running 12psi (r34gtt), once the car hits 5500 it picks up goes great, and if I feed the accelerator on slowly it doesn't hesitate, I was thinkin coils or afm?

coil packs i had the same problem with my 33 but then again i have a FMIC and 12psi sort of makes a sputter sound while climing the rev range aroun 4k -5500? if she hits rich and retart she normaly sounds like its droped a cylinder just pull over till the ecu fixes it self up

That idle issue I've had before and it was because the solder in the afm had become brittle.

There are some DIY threads on here if you search for "AFM Solder".

Or it could just be that your afm plug has become brittle from removing it so man times.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure

      Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15

      J50 clock date suddenly reset to January 1

      Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.

      Wheel Sizes & Offsets For Skylines

      8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
