Hey all,

I've searched the forums a bit and found that people are saying that it's hard to get an acccurate reading using a timing light on an r33 gtst!

I checked my base timing by using my timing light I have and found that it was showing 6 white marks past the orange one.

Does this really mean that my car's timing is advanced 30 degrees??? cos I've heard that timing is hard to check with a normal timing light on an r33 and that the readings that you get are double what it actually is???

That would mean my timing is 15 degrees which is correct. The car has been running for months and i've never had a problem on this timing setting so I have a feeling that it prob is actually 15 degrees. To be safe for the time being, my tuner retarded it, but that has robbed me of precious power and I think that the readings we are getting are wrong.

Can someone please help and shed some light on this!!!!

How can I get an accurate reading of my base timing???? I'm happy to take it somewhere and pay for them to check it if I have to!!

I need urgent help.

thanks

Hi Black 33,

First Qion what/how are you hooking the timing light up to read the ign puse ? As there are a couple ways of doing it !

I'm would be happy to help you in this matter in return for your vin number so my mate can get a water pump for his ser 2 RB25 in a R31 as we might of found today that the blocks are diff between ser 1 and 2

Well I am having a timing problem on my Series II motor. Mine always reads far advanced like 30 degree's. When I first got my car running I had the sensor almost fully advanced and it red 15 degreee's Car ran great! Then after a few days the car started to run slugish. I checked the timing and it was off the scale. I set it back to 15 degrees again. Now the sensor is in the middle of the range. When I set it to read 15 degrees the car runs very slow. With it set farther ahead it runs better. I turned my boost up to 10 psi (Everything stock except 3" turbo-back and HKS SSQ BOV) My car shoots flames between shifts. Is this nomral? I guess a S-AFC is needed?

two places to take timing from on series 1 (that I know of).

1. there is a loop on the back of the ignighter - this will give you double the actual timing, so if you see 30deg on the engine, its acutally 15 deg.

2. remove the cover off the coil packs, and take the signals from number 1 - this will give you the actual timing. A bit more accurate than method 1.

not sure if it is the same for series 2, but you can guarantee if you take the signal from no 1 coil pack it will be accurate.

    • Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist
    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • 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
