1990 240SX Autocross Build (DSP)

[nismofly]

are you allowed to run spl's endlinks on your whitelines?

also by seneca lake you mean the events at the army depot?

ive considered running there from time to time, maybe ill head out this summer

[91rs13]

i'm quite curious about those Koni yellows. I'll really wanna hear your impression once they're on

I have been running the Yellows for a few years with the GC kit ( 550 frt and 500 rear) --I like them. nice handling, good response.

to the OP I would rethink the 14 inch rim idea. I have run 15 inch Rewinds ( 15x7 +0) with 225/50/15's and 225/45/15's and have no issue with acceleration ( it is a CA18det ) --with the KA you should have plenty of torque to turn the wheels) --14 inch options in R Compounds are tougher to come by.

I would seriously look at a 16 or 17 inch option --or at least a 15. The 16's and 17's are more $$ --but you have the room.

Also --if you want a set of 15x10 4 luggers and would like to run the 275-35-15 Hoosiers --I will sell a set of rims cheap. I cannot use them on the track and want one rim for both AX and TT ( non SCCA TT club requires tires inside OEM fenders--and only 2-3 hot laps at a time)

Also--Replace all bushings you can --I ran whiteline but energy suspension has a kit now.

See Ya at Seneca ( Street Mod --#381)

Oh and Porterfield R4S is a nice AutoX compound for the stock brakes.

I am running the R4 on the track and am not as sold on that as I am the R4S

Also if any of you NY'ers want to play on the track --check this thread out on the Mohud SCCA forum --there are a few of us who are HPDE/Time trial people who are not club racing--but go to the track together

Not sure about the SPL endlinks, I think the Whiteline endlinks should be fine.

Yeah, the events are at the army depot. It's a great site. The courses are long and fast (80-90 second range, which is about double a usual course length). Definitely check it out if you're free. There's usually at least 3 or 4 events there, although the regional schedule isn't up yet.

hopefully i can get a 240 before the season, maybe an s14 this time

You're welcome to ride shotgun at one of the events if you want...I'll let you know if I see anything for sale around here.

I'm looking at the 14" or 15" wheel/tire combo mainly for cost reasons at the moment. Plus, this is my first set of R-comps and I think tires much wider than 225 may be too big a jump from street tires. It would be nice to have those 15x10s laying around if I wanted to try something wider...How much would you let them go for?

If you take your car to real road racing (SCCA) what class would it fit into?Or will you need more mods?

[nismofly]

nobody runs cars with full interior and no cage in real road racing

its why i find scca's auto-x class structure antiquated, because a fully stripped interior puts you in a class where cars are allowed to be tube chassis (afaik), but yet youre in a lower class if youve got built 500 rwhp motor but retain interior

rediculous if you ask me

as for what class he would be in with a few changes, strip interior and add cage with the DOHC engine hed be in scca ITS probably, nasa PTD

whiteline endlinks are urethane and prone to binding, the SPL endlinks are solid, so not only will they cure the binding, but theyll be far superior overall...just not sure if youre allowed the solid endlinks

and ill definately try to make it out this summer, i think im going to try to stick with STX-ish level stuff while my car is still street driven

[nissanman04]

It's pretty close to Improved Touring, however I don't really plan on going that route with this car.

btw, I put up some crappy pics in the first post...

I would lean towards no on the SPL links, since bushing type may not be changed, as well as the amount of metal in the bushing may not be increased.

The 275's are a jump. Rims are steel Circle track rims--I guess $50 ea --I have 5. BUT the tires are not cheap the A6 in that size is $237 retail. (There are 4 worn out ones on the rims now)

You can run a full cage or roll bar in any SCCA Solo class. Most people do not because it is added weight and especially in the Stock classes or STS/STX the cars are street driven for the most part.

If you look at a Showroom stock club race car they must retain the stock interior but still have a cage.

You do not have to gut a car to install a cage, but most people remove interior to lighten the car rather than cage installation. Solo rules in certain classses prohibit that to keep the playing field level.

Even my SM car has to retain certain trim ( I disagree with those rules by the way) --but if I wanted to remove the trim --then I could move to Prepared.

Nasa rules are much easier to follow though. I like the points system for modifications.

[mirochuki13]

Hey. I'm looking forward to seeing your car come together. I'm building my S13 to run in STS next year.

By the way, you can get adjustable RUCAs with stock-type bushings from SPC Performance:

yeah thats sort of what i was getting at, is that while you can keep it, its not required in anything besides showroom stock so theres no point to keeping it...and keeping it does compromise the cage design to an extent

but i believe that if a car isnt allowed to something as cheap and easy as remove at least some of the interior, then they shouldnt be allowed to run rediculous power levels and tires, just seems like a crazy imbalance...and it also favors people with higher budgets, similar to most scca classes

anything above STS and X to me for auto-x the rules just get too crazy

Yeah I have seen those arms. It's cool that the bushings are stock-type, but I'm not sure if adjustable-length arms are allowed even if the bushings are the correct type. Anyone know for sure?

[240marcuSX]

Hey, nice build you have going on so far.

I ran my 240 in DSP for about 2 years before I parted it out.

I still have the DSP legal oem TC rods with PDM bushings pressed in, and very slightly used Hawkl HP+ pads, if you're interested. I've been trying to get rid of them for months.

Let me know if you're interested.

Cool, how did the car do when you were in DSP?

Thanks, but I've already got some OEM tension rods w/ energy bushings and I already have brake pads.

[hbpignosePA]

i bought your konis right marcus?

hes a good selleractually wat r u lookin for for those tie rods?

ha maybe ill take em off ur hands

[240marcuSX]

cool man. Im looking forward to seeing the progress.

The car did very well in the class, and mine wasnt as built as yours is going to be.

hb- im not sure what to ask for them, it was posted in my FS thread, let me look. For clarification they are Tension Control Rods, not Tie Rods.

[mirochuki13]

I know they're legal in STS, not sure what the DSP rules say about this.

I might just take you up on those Hawk pads... What rotors did you use?

[240marcuSX]

I was working at napa at the time, so I used 4 premium napa rotors.

The pads were awesome. Keep in mind that they squeek on the street, and dust. They are mainly a track pad, and I only really got to use them for a short time driving to VIR and on track in the rain, so they never really got up to temperature.

ya thanks man. When you start building, lemme know if you might need help

[nissanman04]

Sway bars, clutch, and shifter arrived

I was hoping more parts would be here by today, but I guess I'll just have to be patient. Not like it really matters, since it's still really cold and wet outside. I wish I lived somewhere that doesn't have winter.

[Soravia]

I think they should just weight cars and put them in different classes according to weight to Engine liter ratio.Of course, rules for engine mods and safety requirements should still be there. But people shouldn't be put off the class because the car has plus size rims or CF hood.

[nissanman04]

Small update...

I've received everything except for the shocks (which are on backorder from Koni). The weather is still not cooperating so that I can get any kind of work done, seeing that I don't have a garage to work in .



I weighed the stock vs. aftermarket pressure plate/flywheel assemblies because I was curious and bored:

stock flywheel: 21lbsstock assembly: 32lbs

fidanza flywheel: 11.5lbsspec pressure plate/fidanza flywheel: 23lbs

total weight savings: 9lbs

A >25% savings in rotating weight is always a good thing!

[nissanman04]

I got a couple days where it was about 35 degrees and sunny (freaking tropical, I know!), so I figured I'd do a little work while the weather wasn't terrible. I pretty much stripped the entire front end of everything except for some electrical stuff which I really have no desire to remove. Once my hose thawed out, I sprayed down the bay with degreaser, to get a lot of the dirt off, then I went at it with a metal brush to get the rest. Found a couple of rust spots that need to be taken care of, but I don't think it's any worse than my last 240 (I really wish I had a welder / knew how to weld).













ooooh and look what finally came...



Well it looks like this is the last work that I'll be able to do for a while, since we will be getting a decent amount of snow over the next couple of days . Have I mentioned how much I hate winter?
