This is more of a public service announcement than anything in case someone else out there is wanting to get sphericals for their S13 suspension. I'm working with Chris Brinson at Kingpin Machine to redo all the sphericals on the suspension in my car. Since this is IT racing it will be all...

I saw some oil temps higher that what I have been seeing while at Barber and am wondering if the oil pump is starting to get tired. It was a really hot weekend so it could've just been the weather, but thought I'd check to be sure. I saw oil temps in the 215 range during qualy when water temps...

Hasn't been a new thread in forever so thought I'd start one. What makes the clutch fork return after it's pressed upon by the slave cylinder? Is it the fingers on the pressure plate or is there some sort of spring inside the transmission housing that pushes the fork back out? I've had a...

I changed right front and left rear wheels bearings a few weeks ago and was able to re-pack them with some high-temp race grease. Here's a little write-up on what I did. I took the bearings apart, cleaned out all the grease, and then re-greased them with some Neo Synthetic. Front bearing: The...

What pads are you guys using? I've been running Hawk blues and they work pretty good, but eat rotors at a rapid pace. I was going to try the DTC-60 compound, but Hawk doesn't make 240sx pads with that compound (I sent a note to Hawk about this). Other options appear to be Cobalt XR1 or XR2...

This is a follow-on to a thread I started over at RRAX about fuel pressure. I've started looking at ways to pull data from the ECU and eventually do some tuning. The stock 89-90 240SX ECU does not have Consult code and thus you can't really pull data from it easily. I have found a few ways to...

What are the best non-OEM wheel bearings? I've read that Timken are typically good. What about Beck-Arnley? Are they as good as OEM? Nissan wants $100+ for bearings and Rock Auto has Timken for $37 front and $80 rear. David

Me again. I'm going through my list to prep the car for the Road Atlanta race later this month. I put on the list to replace the control arm ball joints since I have no idea how old they are and the boots for the front ones are ripped up pretty badly. I got some Moog replacements and the...

My power steering pump is leaking. Looks like it's from where the back cover mates to the pump housing. Presumably the gasket is leaking. Courtesy parts shows a power steering pump seal kit with the gasket for $21. Anybody ever replace this? Is it a simple job of taking off the cover and...

What did you guys do to disable the steering lock? Any easy ways to do it that don't involve taking apart the mechanism? I got dinged for not having it disable on the new car at my initial inspection. Thanks. David

I'm going to re-do the ignition switch circuitry in the car. In looking through the FSM for the key switch workings, I noticed that it shows the ACC circuit is disconnected when the key is rotated to the start position. The ON circuit is still connected. What's the reason for this? Is it so...

Title pretty much says it all. I get to pull two motors to swap the one from the current car to the new tub. Never done it before. I'd like to leave as much on the motor as possible since I don't need to break it down. What's the preferred method and attachment points? Anything specific I...

This is a tech question along with a rules & regs question, but I didn't feel like making two different threads. I'll be having the roll cage built for the new tub in a few weeks and had a couple questions. - The cage in the current tub does not have a dash crossbar. There is a stock...

Specifically the RPMs. This is from Road Atlanta last weekend. http://www.youtube.com/watch?v=JyLeJQfSFLE This is the first time I've really looked at the RPMs I'm turning. I had been using the stock tach and it had been going up to close to 7000 before it died, but the data is only showing...

I'm prepping the car for racing at Barber over Labor day. Got all the fluids changed and cranked it up. It's been many, many months since it's been started. It started right up, but the oil pressure seems low. I was seeing around 20psi right after it started. It's in the 80s outside, but I...
