Well I went out on the track with slicks and a stock oil pan for 3 years, then one day my ex-roommate blew his engine in the long sweeper at Buttonwillow on his 3rd lap of the day. I upgraded my oilpan despite never having had a problem before. To me it is just extra insurance, and since I like driving my car a lot more than fixing it, I'm gonna do it. Plus the more worn the LSD is the more it will slip, the more heat it will generate. Jon

That's funny baddriver! I always wondered how you turbo guys can monitor 17 gauges at the same time. I would prefer idiot lights for most things, with gauges for the simple stuff: coolant temp, oil pressure, volt or amps, gas. My ex-bosses 911 race car had a what seemed to be 2000 watt bulb hooked in for low oil pressure. Made those shift lights that come with autometer tachs seem dull. Seems like that is the way to go, so that you can concentrate on what is in front of you... Jon

240zprace, why didn't you just disconnect the sway bar? Seems easier than lifting the engine to me, so that's what I've always done. Jon

Wanted: Steering Wheel Advice
JMortensen replied to jeromio's topic in Brakes, Wheels, Suspension and Chassis
I've tried stock, 15", 14", and 13", and I think 13" is the way to go. With the bigger wheels at autox I'd constantly hit my hand on the door panel, and I "shuffle steer". Jon -
Subframe connectors on 280Z and sway bar issues
JMortensen replied to PETEW's topic in Brakes, Wheels, Suspension and Chassis
Could you make some spacers to space the bar down away from the connnectors? I've been contemplating doing the same thing to avoid CV shafts and not have to replace the rear bar. I don't even have the CV's yet, just trying to think ahead... Jon -
I've run mine with a 79 ZX cover for about 4 years. No problems at all, and I've had it out at the track many times. I am going to get the LSD cover on there eventually, because LSD's do generate more heat than an open diff. Jon

No, it is a viscous LSD in the '88 SE. IMO, the clutch style gives better traction since the VLSD needs to start slipping before it does anything, but the VLSD will be smoother and won't affect turn in as much. Supposedly you can tune the VLSD to be more aggressive by changing the fluid in the VLSD unit itself, I've never tried it but that's what I hear. Jon

14" slots weight question
JMortensen replied to BillZ260's topic in Brakes, Wheels, Suspension and Chassis
http://www.ups.com http://www.fedex.com Both sites have rate finders. Fedex Ground is usually cheaper. Find a box that will fit 2 wheels and send 2 boxes. Put a couple pieces of cardboard in between the wheels to keep them from getting scratched. Jon -
Yeah, but that '78 Toyota Celica that some redneck runs on 1/8th dirt oval that would do a 20 sec 1/4, yeah, that's a REAL racecar. Sorry, still not buying it. Jon

UPDATE!! Upgraded fuel pump issue SOLVED but some more Q's
JMortensen replied to a topic in Turbo / Supercharger
Yeah, I wouldn't want to drive Bastaad's car with it running on cords on the right rear! Jon -

As someone who has thrown a lit cigarette into a jar of gasoline to prove that it won't catch fire, I can tell you that walking by gas fumes with a lit cigarette will not start a fire. There MAY be some ideal set of circumstances, ie you just took a drag and the cherry is as hot as it is going to get, and the fumes are at just the right density, but under normal circumstances it won't happen. LIGHTING a cigarette near fumes can. And yes, even though I knew it wouldn't catch the jar of gas on fire, I still winced when I threw it in. It's that whole self preservation thing, I guess. Jon -
I don't know for sure about this, but it seems to me that in a previous post there were pics of the mating surfaces and this was not a locker. I know it looks like one of the little "lunchbox lockers" like an EZ Locker or a Lock-Right that you would get for a 4x4 that takes the place of the spider gears, but I seem to remember a friction surface in the middle of the 2 plates, not teeth like a locker would have. I would imagine that anyone who had one would have complained like hell if it was a locker. If you've ever been in a 4x4 with an EZ or Lock-Right you know what I mean, clunk BANG, clunk BANG, clunk BANG around corners. FWIW, a friend of mine did have an actual Detroit locker in his R190 in the back of a 510 about 10 years ago, and that thing was FAR worse than a 4x4, probably because there aren't leaf springs and shackles to isolate the clunking from the chassis. I swear the first corner he went around I thought the diff had to be in a million pieces in the middle of the street. VERY LOUD. He took it out after driving in the rain and trying to exit a freeway off ramp that had a sharp turn. Only took one... Jon

Sorry no. I just looked thru all my old backup CD-R's and nothing. I had to format the old hard drive a while back and apparently lost ALL of my old pics of the Z, which included my engine buildup and headwork and everything else... BUMMER! Crappy thing is I know I had pics of the engine going together and the pan going on and pics from all different angles of the engine compartment and suspension, so I KNOW it would have been in there. Got 5 copies on 5 different backup CD's of my wife's school projects from 5 years ago, but no old Z pics... Jon

The fins hang down, but that's about it. I don't think it is significantly lower than a stock pan. It does not hang really low, maybe 1" or so under the crossmember. The benefit of the engine getting oil under braking and in turns would far outweigh the danger of it hitting anything, in my case with my ride height at least. And the cost of a Nissan Comp pan is pretty ridiculous if you ask me. Don't try going direct to DP for the comp pan, BTW. When I called him he told me I had to buy direct from Nissan, so I ended up with the AZC pan instead figuring that $400 could do lots of other things for the car. Jon

What if you're SCCA national champ in the stock autox classes? I'd say it is a race car... Jon
-
Nope, they use a pipe plug and mine actually tightens about 5 threads into the pan, so it is well protected, if somewhat leaky. Might be that someone had the same pan and didn't like the drainplug and made their own, or perhaps that was an older model. Jon

URGENT BRAKE QUESTION
JMortensen replied to philiow313's topic in Brakes, Wheels, Suspension and Chassis
I think this piece can fall out of place and down inside the booster. Should have mentioned that before... Jon -
Maybe Malvern buys from AZC then??? It's obviously the same pan. Jon

URGENT BRAKE QUESTION
JMortensen replied to philiow313's topic in Brakes, Wheels, Suspension and Chassis
There's a spacer thingy in the booster that sounds like it fell out when you replaced the master. I haven't seen this thing myself, but I've seen several threads that match your description to a T, and this thing was the culprit. If I understand it correctly, the spacer takes up the distance from the pin on the pedal and the back of the master, and is actually inside the booster. Hopefully someone else who has run into this problem will see this post and give you a better description of what I'm talking about. Jon -
Well I definitely wouldn't pay Malvern an extra $70 for it, even though they are much better to deal with than AZC. I'd make sure that the AZC pan comes with the bolts. They weren't hard to find, but I seem to remember them being relatively expensive, like ~$25. Jon
-
Actually, I just heard Audio Slave's "Gasoline" the other day. That might be appropriate. Or Bastaad's "Crash". Jon

One word for you Alex, Cottonelles... Jon

I agree with Terry, but I still have to laugh when I say in my most sarcastic squid voice "I'm going to go for a drive in my race truck!" which is a '93 Toy P/U that I autocrossed for 3 seasons. Yes, it is a "race truck", but no, it is not a "race truck". Jon

It's good, but HEAVY. I was really surprised. Gotta weigh 10lbs at least. I'd say buy it from Malvern Racing, as they make it (I'm pretty sure) and are very cool to deal with. My drain plug always seeps just the tiniest bit. I would have preferred a drain bolt instead of a pipe plug, but it barely seeps if you use PST or something similar. I bought mine from AZC, and it didn't come with bolts or a gasket, on Malvern's website they show it coming with both. Not too big a deal, since I always use silicone, but the bolts would have been nice... Jon
