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.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.

      Neg, the top one is actually for the front. The sizes are 18x10.5 +18 and 18x11 +32.   I measured many times but I'm sure I'll have problems as this is the thread for problems.

      Just one thing; tapping tapered threads is tricky. Taps are always tapered and you would generally run it as far as you can, but with a tapered thread you have to stop much sooner otherwise the wide part of the taper will run in too far and you will have to thread the sensor in too far too as well (possible that it will never make a good seal) BTW nice wide wheels, I guess the top one is for the back!

      Welp, good to know. Will have to wait awhile until steady hands with drills and taps are available. In other news, these just arrived! I will weigh them for posterity. Edit: 11kg each (or 10.9/11.1 depending on what my scale decides over multiple tests, the 18x11 don't seem to weigh noticeably any more than 10.5)
