Hey guys

Reeeeall stupid qusetion and i cant find it no where

What is the exact sparking mesurement for the spark plugs (RB20DET)

Iv found n bn told 1.0mm

1.1mm

0.08mm

I had them all at 1.0mm and it was missing as i was coming on boost fairly mild

took them out made them bit smaller roughly 0.9mm and its running a hell of a lot better now top end high revs is missing???

Sooo im thinking its smaller again!

Just so i dont have to take it apart again, What u guys reckon

Cheers

With an N/A engine 1.1 is the standard and that is what most plugs are out of the box.

With a force inducted car you get away with what you can but most people will run around the 0.8 mark.

Also be careful with platinum plugs (which i will never use unless i own a car which is a bitch to change plugs) not to touch the electrode as the platinum coating is only a few microns thick and if you push a screw driver in their trying to gap a plug you will ruin it.

      Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.

      Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.

      Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers

      The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work.
