Shouldn't be that bad at all with headers and exhaust. I'd do it! FWIW, my 33x13.5's are mounted on 15x8.5's with 4.25" BS and no rubbing after trimming.

WD21 87-89 V6 with the H233B/R200A combo has 27 spline CV axles, 4-cyl with the C200/R180 combo has 28 IIRC. The rear diff in an 00-up (IIRC) R50 has 33 splines... 31 on the rear diff for 87-95's.

I recall there being a molded grommet that it pushes into, yes. I think a dealer or junkyard are your only resources for that one.

Sure it is. The only other hole in the tranny is the vent tube that goes all the way up the firewall under the hood. You can park a Pathy pretty far over and it won't leak.

I thought hydrogen sulfide production was a result of the cat being worn out. I never smell that from new cars.

I believe you have two pre-cats at the base of the exhaust manifolds, then the resonator tubes, then the cat, then you have a resonator and then a muffler with a tailpipe. Crazy, huh? Get yourself a factory service manual, there are several places you can download one for free, like phatG20.net.

Fixed that for ya.

87-89's use Dexron III in the t-case. You can switch to gear oil if you want. Like mzxtreme said, I don't think it makes any difference. The 90-95's all use gear oil and the transfer case design didn't change one bit. GL-5 in the differentials. GL-4 in the manual tranny. Redline MT-90 works fine. I'm surprised it was tough to find this out. They list the proper lubes in my Chilton's book.

Your alternator's taken a crap on you or the belt broke. Those lights all come on when the alternator dies. I've driven 80 miles on an Optima alone and it still started when I got home.

Transmission type was customer-optioned on XE's and SE's, but I believe all the LE's were autos. I could be wrong! I think that's why some of the axle gearing ratios don't match on some of the autos vs. manuals I've seen in the junkyard and read about. Maybe they pulled a new pre-built chassis off the line and swapped trannies for a customer order (if the pre-built new Pathy had the correct options/package but the wrong trans? I dunno, do you think they went to that length back in the late 90's if someone custom-ordered a Pathy, or would they build one from scratch with the selected options? Supposedly, autos got 4.6 gears. Manuals got 4.3 gears. I've seen autos with 4.3 gears and manuals with 4.6 gears. So...yeah.

Ditto, from what I've read from several Nissan techs you can re-use the head bolts.

You can try going up to plus 4-6 degrees but it really doesn't do much, if anything. Might help with higher octane gas and at low altitudes. I dunno, give it a shot and see what you think? I've heard from several other people going with +4 degrees full-time, no problems.

Some of the iridium plugs run $12 each.

NGK plugs work fine, so do Bosch Platinums from what I hear. Plug wires don't really make much difference. Make sure you have a ratchet, extensions and a u-joint before going after the #6 plug. Or use the spark plug removal tool that should be under the rear seat if it's still in there. If you have the manual transmission, up the dosage of gear oil to 5.1 liters instead of 3.6 liters like the book says. The fill hole was located too low on the case on the 5-speeds from 87-96, so it needs more fluid for proper lubrication of the internal trans parts. One way to give it more is to jack up one side to tip the vehicle far enough to allow addition of more fluid, or you can remove the gear shifter and pour it in from the top if you feel adventurous.

You can always order Redline lubes from Summit Racing or several other online vendors. Just a thought.

The headers are cheaply made in Mexico and some people have problems hooking up the EGR tube cause they tend to be off-angle from the factory. The y-pipe is another point of contention, take a little flashlight and peer inside from the end right at they 'y'...mine had a hole the size of a quarter blown through it with a torch and then they welded the other tube right on top. Nice. I'm going to build my own y-pipe with a proper sized hole when I get the chance. Aside from that, lots of other people have the Pacesetters and they work OK after you get all the install kinks worked out. The tubing is nice and thick, so I don't think rusting out will be a problem. I plan to paint mine with some hi-temp silver exhaust paint and see how that goes. I did a set of Edelbrock headers with the Duplicolor stuff and they looked just like they'd been Jet-Hot coated.

I'd have to see pics of the wiring to comment. It could be anything from a crazy stereo install to a simple missing ziptie.

They're actually 6mm bolts with 10mm heads. I drilled and re-tapped mine to 1/4"x16 and used anti-seize on the new bolts.

Several people have. They're easier to access through the fenderwell FWIW. All I have to say is that if they're in good shape to begin with replacing them isn't going to do anything for ya.

I think that'd be fine.

The light will come on if your wiring to the ABS sensor is toast also. The ABS sensor is on the top front of the rear diff.

I HIGHLY doubt a 10% increase in MPG by simply installing different plugs. If it's all that easy they'd have done it already to get away with better emissions testing standards. 99% of the spark plug gimmicks are just that. Gimmicks meant to drain people's wallets. Anyone can make up test result charts.

I would oppose that view, a body lift gives you permanent tire clearance. Suspension lifts only give clearance at a standstill, over bumps the suspension will cycle up and down and you won't keep the clearance. A 2WD is basically a simplified version of 4WD, you may want to make sure your driveshaft will work with a BL since 2WD's have a two-piece driveshaft mounted to the rearmost crossmember with a carrier bearing. Other than that I can't think of any reason why a BL wouldn't work on a 2WD.

Thank god you got to the t-belt before it snapped! Good job, man. Sounds like a good time.

No, but I bet they make some for 300ZX's. Only problem is I don't know if the belt types match. VG30i's have all v-belts and the VG30E's have one ribbed and two v-belts, unless I misremember. In any case I doubt it'll make any difference. It might if the Pathfinder weighed around 2200 lbs, but they don't. They weigh more like 4000.
