Thanks, I think I'll try that, or maybe some JBweld to hold it in there.

ah crap, well that explains the wear on 11 and 12, the previous owner must have run it like this for a while. it was sitting like the first pic when i pulled the vave cover off. thanks for clearing that up. maybe this is a good time to swap in a bigger cam.

The engine is a stock L24. This thing fell out while I was adjusting the valve lash. What is it and does the hole go on the top or the bottom? I am guessing that it is some kind of oil filter. Here are the pics:

not really, Double wishbone is used on racing cars because of the adjustability, favorable negative camber gain under compression, and lack of toe change over the range of suspension travel as compared with other suspensions like semi trailing arms. Ride comfort is more dependent on reducing vibrations being transmitted to the driver or passengers from the bumps in the road. Comfort is greatly improved with chassis stiffening, sound deadening, new rubber bushings, large sidewalled tires, softer springs, etc... Every suspension is a compromise of performance, cost and space available. for example, macstruts that are used in the Z are a simple design that is cheap and fits in small areas. good for an inexpensive, small, sporty car. Double wishbones have more parts so they are more expensive to produce and require more space, so you will see them on higher end sportscars.

Yeah, I know, I know I was just putting it out there because some of the stock class drivers run way overdamped since they can't change springrates.

One question, although I know this is the wrong way to do things: I have found that tokicos generally have a lot of compression damping and not enough rebound damping, so would it be beneficial to pair the tokico illuminas with the softer ST springs but set the shocks to full stiff. This would theoretically increase the springrate on compression and hopefully keep the suspension from bottoming. Also by using the softer springs, the illuminas would be able to control the rebound better. The reason I would even consider this over a stiff spring/koni setup is so I could soften the shocks for street driving and it would cost much less. Is my theory completely off or is this a plausible compromise for price and streetability?

Thanks for the quick responses, that settles the springs and the shocks dispute. I was leaning that way anyway as I currently use konis on the maxima and they are way better than the tokicos I had before. I dont think solid bushings are allowed anymore, the rules state: "Suspension bushings may be replaced with bushings of any materials (except metal) as long as they fit in the original location." Im really not expecting to be that competitive with a street driven car, because this is a pretty competitive area (Washington, DC and Philly region) We generally have between 150-280 participants at each event and there are some serious cars in BSP around here. I should run the 275/35/15 hoosiers to be more competitve but those are a little bit outside my pricerange for now

I just bought a 71 240 to build into a BSP car for autocross. I am completely new to Zs but I have been autocrossing and working on cars for about 5 years. I am on a tight budget and I would like to keep this car streetable but still competitive locally. Here is what i have planned for the suspension: 225/45/15 tires (Hoosier A6 or Toyo RA1) 15x7" or 8" wheels 4" Backspace AZC springs with 1"f, 3/4"r sways OR ST springs with 1.125"f, 7/8"r Koni shocks OR maybe illumnas Strut tower braces Poly Bushings everywhere except TC rod Is there anything else I should do to the suspension. Any advice is appreciated. TIA. Here are some pics of the car: Here is my current DSP car:
