Hey all,

I got a r32 gtst-t RB20DET and a few weeksago it was running on 5 cylinders. I unplugged coilpacks one by one and found cylinder 2 was no go. I pulled out the sparkplug and coilpack and cleaned them, put them back in and it was good.

Its just happened again. Yesterday i change oil filter and oil. Then regapped plugs from 1mm to 0.8mm (with feeler gauges) Then started car and it was running on 5 cylinders. Checked them and it was cylinder 2 again. So i bought new plugs and put them in and still same thing. Then i pulled the coilpack off sparkplug and left it connected, started the car and it was definately working as electricity was coming out.

Still no good.... so i compression tested motor and it has 150psi across all cylinders. What could be happening?? Im thinking maybe the igniter??

I bought splitfire coilpacks.. on their way.. but im geussing they dont have a new igniter. Are there any cheap aftermarket igniters? Are r33 and r32 igniters the same? Or is it definately not the igniter///?

cheers

i changed the plugs thinking they may be at fault.

The coilpack is sparking but some one PM me and said its easier for coilpack to spark to atmosphere than it is when its inside engine..

As for the loom.... i have llooked but not many wires are uncovered... i will try a mates loom and see how it goes..

also a question... i had the coilpack plugged into loom but not on sparkplug... turned the car on and sparks were coming from underneath where i expected at bottom of stem... but also at the top... is this not right?? Or is it meant to spark there too. Im guessing its not. Ive been told to put silicone on my coilpacks to increase their performance but never understood what they meant... im thinking maybe put silicome at the top to stop loose sparks??

thanks

ok... so still having troubles really in need of help.

Sum it up... cylindr 2 is not firing still. I know this cause when i unplug cyl 2 coilpack look it stays same (running bad) then any others makes it worse.

Remedies i have tried to fix it but to no avail..

Brand new Colder NGK Spark Plugs

Brand new SplitFire coilpacks

Igniter off a working skyling

Coilpack loom

Compression tested to 150psi

STILL NO GOOD!!!! What else can it be!! Im in dieing need. Please help

Have you checked that its not fuel that is the problem in #2?

Is the injector firing?

jus spoke to mechanic today nd he said to check if injectors r running. I dnt really know what im looking for but i geuss ill put a pices of steel rod against injector and use it as a stethascope (sp) and listen for a little tick. If number 2 had a dull sound it obviously isnt wrking correctly. But he said it still might tick but fuel just might not be getting through.

Ill check this sometime tomoro or sunday and post up.

cheers

    • So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you  
    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'  
    • D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.
    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
