My 2nd favorite car I've owned/driven (next to my 280) was my POS stock '93 240sx. The clutch master leaked onto the carpet, occasionally would throw codes preventing it from starting but was easy to bypass, door locks didnt work so I had to crawl through the hatch every time I bothered to lock it, and had been through a hail storm making it look like a giant golf ball. I loved that POS. It was probably my most fun daily driver of all time.
Sliding in gravel, dirt, concrete lots and not giving a **** how it looked. Easy and cheap to work on. Ramming shopping carts in the Wal Mart parking lot. Getting a little air borne in a local construction site that never saw any progress. Easily having 9 or 10 240's + an FC (88 RX7) in front of my house most friday and saturday nights was awesome too. They're really great, fun DD's if you abuse them a little. I think it helps to be young and dumb. I had this car when I was 16-17. The track car I got rid of in January of this year.
My SR20 was really finicky. If you do go the SR route, I'd recommend rebuilding it or staying away from Canadian importers, I can't remember the name but they spoke a mix of French and English and shouting if that helps anyone remember dealing with them. These cars can easily turn into an enormous money pit but it's so worth it. They can handle amazing and bringing power out of the SR or anything else commonly swapped in them is very easy.

After being kicked out of a local lot for sliding, we went to another and messed around. Mainly laying on the roof with the car in 1st and steering from there. Yes, there are two cars in that picture. I think it was cold, hence the terrible quality.
And the track car I shouldn't have given up on.
