My car is missing in high rpm so I thought I'd check the coil packs. They all read 1.2 ohms when you measure as per the instructions

http://www.powerlink.co.nz/~graeme/faq/30.html

As they are all at this level I am thinking there is a chance it is the $20 multi meter more so than the coil packs

I have my dodgy multimeter dial set to 200ohms, is this correct?

Also how do I test the ignitor/amplifier?

Set the meter to the lowest scale possible to get an accurate reading. If you touch the leads on the meter together, you may get a reading on the meter. e.g. 0.4 ohms. This is the resistance of the leads and must be subtracted from the reading you get when you check anything. i.e. 1.1 - 0.4 = 0.7

Anyway, as long as they're all reasonably close, they should be fine. If you're really unlucky, one coil might be going open circuit when under load. If you know any sparkies, they'll have an insulation resistance tester which can pump 500v or 1000v through the coil (as opposed to a multimeter's 2-3volts). This will find very small breaks in the coil which won't show up with a multimeter.

Yep, I did a search on coil packs. I could not see cracks on any of them but three are not original coil packs so it has had problems before (one is off a CA18).

I just checked the multimeter reads .4ohms resistance so they are all .8ohms so they are fine.

Any idea on testing the ignitor with a multimeter?

(BTW its running a little smoother with the carbon tips cleaned)

Car is running fine now, I cleaned corrosion off the ignitor and cleaned the carbon tips (like I said before) It is pulling all the way to 7000 with out missing and boy does she bang into second gear.

No I haven't, I am far too lazy that even when I had the coil packs off I couldn't be stuffed pulling the plugs out.

What gap should I run in an RB20DET running 13-16.5 psi? (I thought it would be different to RB25DET b/c of the different compression ratios)

    • Yeah good luck out there! Will be good to see a mighty GTST going harder than the GTRs
    • i will be there 😁
    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
