hi, i've just recently picked up a series II r33. i've noticed that sometimes when i boot it, it has a really slight stumble at about 4000rpm, then at about 5500rpm. its only very slight but you can feel its not revving freely through the range. sometimes it doesn't do it though.

i was thinking spark plugs but what do you guys think

its got standard ecu, hks filter in the standard box, 3 inch cat back but running standard cat for compliance (haven't got around to changing it) oh and running standard boost.

Sounds like a slight misfire which isn't uncommon.

Change the plugs first. A set of copper bcpr6es or bkr6es will cost about 20 bucks. Or pull out your existing plugs and check that they are gapped correctly. Factory recommended gap is 1.1mm, gap them down to .8 as you will be running a bit richer with the mods you have which will contribute to the miss.

Then start looking at the coils. There's a sticky thread at the top of this section all about them.

How would one alter the gap?

A set of feeler guages (you can pick them up from any auto store) & by lightly tapping the end of the plug on a hard surface, Ie table etc. untill they meet at 0.8mm.

Most decent auto stores would possibly gap them for you if you ask! :(

There seems to be some conjecture about whether or not to gap iridium plugs. I've got some on my desk and would really like to know =D I got the BKR6EIX-11's which as I understand have a stock 1.1mm gap, the recommended gap seems to be .8mm Should I be re-gapping these? The car is stock engine/performance wise just wanted these for longevity and this is my first service so wanted to be sure plugs were fresh.

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
