Hey guys,

I've recently just had to regap my current plugs in my rb25det to the .8mm mark to fix a misfiring problem I had because of air flow upgrades which has completely fixed the problem for now. However, I am thinking that I will be purchasing some NGK BKR5EIX-11 sparkies to fully replace these. Will I still need to regap these plugs down as well or not because of the better performance of them?

Cheers,

Dallas

The gap should go down as the boost level comes up, to a point.

Mine runs best at .8 @ 14lb, use to breakdown a far bit at .11 @ 14lb high rpm.

+1 for copper plugs, just change them at every service, cheap/easy and you always have a good plug, dont believe the hype for the plugs that they say last for 100,000k, they are good for the first 5,000 then average from then on.

There is a good thread in here about plugs, all about heat range and gap size.

You want BCPR6ES - the BKR plugs are slightly shorter or longer by approx 2mm (cant remember exactly)

The BCPR6ES are gapped to 0.8mm they are copper, they are cheaper and they work just the same.

If you really want to you can deposit the money I just saved you into my account.

Read the spark plug thread - all of it.

these plugs are what most rb25det owners use

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
