HI ALL I GOT A R32 GTR 1989. HAS A APEXI POWER FC Z32 MAFS, CAMS, COOLER, INJECTORS THE NOMRAL STUFF

JUST HAPPENED OUT OF NOWHERE WHEN TO DRIVE IT STARTED IT UP MOVED OUT OF DRIVEWAY WHENT TO TAKE OFF AND IT DIES IN THE ASS.

PUT IT IN THE GARAGE AND SAT THERE WILL REV BUT WITH HESITATING WHEN U PUT URE FOOT DOWN LIGHTLY AND HOLD IT THERE BUT WHEN U STAND ON IT IT JUST POPS AND FARTS AND BACKFIRES THROUGH THE INTAKE AND WONT GO OVER ABOOT 2-3,000

CHANGED FUEL PUMP AND HAS POWER AND ALL GOOD

CHANGED FUEL PUMP CONPUTER IN THE BOOT AND THE RELAY NOT THEM

MAFS ARE BOTH WORKING AS FAR AS A CAN SEE. TOOK TOPS OFF AND LOOK OK. BUT NOT 100% AS I HAVENT CHECKED THEM ON ANOTHER CAR OR VISEVERSA

NOT TOO SHURE ABOUT COMPUTER HAVENT GOT HAND CONTROLLER TO CHECK IT OR ANYTHING

INJECTORS AND COIL PACKS ARE GOOD.

CHANGED COILPACK WIRING NOT THAT.

CHANGED SPARK CONTROLER OR WHATEVER IT IS ON THE TOP OF THE COILPACK COVER NOT THAT

CHANGED EXHAUST CAM SENSOR NOT THAT

TURBOS ARE FINE.

PRETTY SHURE ALL THE HOSES AND ALL ARE STILL FINE.

HAS GOOD FUEL PRESSURE.

IT SEEMS TO REV A LIL BETTER WITH HIGHER FUEL PRESSURE BUT CANT FIND OUT WHY IT WOULD BE IT SITS AT AROUND WHAT IT SHOULD BE ACCORDING TO THE MANUAL MAYBE A LIL HIGHER.

IF ANYONE HAS ANY OTHER IDES OR CAN HELP ME OUT WITH MAYBE BORROWING A MAF SENSOR OR ANOTHER COMPUTER THAT HAS ABOUT THE SAME MODS SO I CAN DEFINATELY RULE THEM OUT THAT WOULD BE SUPER. AND COMPINSATED THROUGHT HE BEER ECCONOMY OF COURCE.

      Mistakes were made, my R34 Story

      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)
