Dirt track setup help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I run an s14 at the local dirt track oval racing. My question is should I weld my diff? Currently has a lsd from factory but in trying to get some more traction to help get the car around the corners.

Also any other set up tips you guys are running.

I'm going to switch the gearing to 4.6. Still messing with tires. And will do a 240/232 cam set up to shoot for more mid range power.

Cars a beast but not winning yet, key to winning is getting around the corner, I can out run everyone on the straights

What the hell is a hard parker???? It that like slidey parking?
Never heard that term before.

Just thought it was sad to see an s14 beat on, on a dirt track.Seems like something a go-cart,pickup, or tractor could do in a less depressing manner.
Poor car

Better that than beat to balls drifting it into curbs.

Also on the oval you want weight on the LR NOT the RR. In order to make a car have grip you give it positive cross weight via increasing RF and LR weight. Weight in cars works as an X, if you add to one front it will also add to the opposite rear. A typical dirt sprint car will run 52% crossweight. The LR tire is the one that determines how much forward drive the car has, the RR is only for sidebite.

This is awesome, do you have any video?

They are doing a documentary on the race track and following me around the last race, had about 7 cameras on the car but can't share them until they say it's cool

There was a greasy line in the middle, I found it. Was close to becoming one car, but not a scratch on either

Agreed, are you in second or fourth gear around the track in your video?

Mega3181 · 06-10-2015, 05:47 AM

2nd to 3rd for gears, ideal I want 3rd gear and never shift

Tried 235 55 r16 on the rear and 2nd goes longer, but I find I can't real people in anymore. So going back down in tire size, change to 4.6 gearing, and work on the stagger to go around

JSimpson · 06-08-2015, 08:25 PM

You need positive rear stagger. And easy-up front shocks. ALSO stiffen the LR spring 50-75 lbs and soften LF spring 25-50 lbs

Mega3181 · 06-08-2015, 09:41 PM

How do you change the spring rates? They are stock spring?

JSimpson · 06-08-2015, 10:23 PM

You get new springs in different rates

the head · 06-10-2015, 04:20 PM

If you are running dirt oval, have you tried corner weighting your car like a Mod chassis? throw a bit of additionall ballast to the outside rear for a more serious hook? dirt is a ton about weight transfer.

Wish we could trade diffs. I want a R200v for my daily just because shorter gear ratio. I would say to actually go shorter than what you have. I dont work with SR's so I am not sure how much extra you need in order to stay in third but I would recommend maybe trying to swap with a NA Z32 Differential. However if second is just shy of where you need it and you find yourself having to upshift shortly before a corner and having to downshift again, I would say the 350 diff would be better suited to allow you to just stay in second.

Z33 - MT - R200V - 3.538
S14 - SR20DET - MT - R200V - 3.692
Z32 - R200V - 4.083

Still a VLSD but shorter gears. I mean, I would recommend trying out a welded diff to see if you like it but if you don't, go with this route.
Just my $0.02

Sorry for all the edits. Been awhile since I have talked ratios, had to figure out the math of it again but I got it now.

accoupe · 06-10-2015, 06:10 PM

All the cars at the dirt oval here run a welded diff. I say go for it!
