Just thought I would share my ideas for my summer project (After completion of the Eldo)
1989-1994 Nissan 240sx. Here's the plan:
Obtain this car cheap. $700 max.
Sell off the engine and trans for $300 or more, depends.
Of course, obtain another Cad 500. Plans for this would be some '76 cc heads, lightly ported w/ dished KB's for 10:1 compression. ~550 lift cam, Potters roller tip rockers, OS valves, Edelbrock intake, and some used Holley or something. Grab a TH400 to go with it, do a basic rebuild on that. Should be good for say 400 horses, 500 ft. lbs.
Next, gut the engine bay. Completly. After re-painting and whatever, I drop the engine and tranny in and figure out mounts. Once all that's done the essentials get wired back up. All a/c stuff goes. Also I may ditch the PS. From there I'll just be running an alt. Also thinking about a dry sump oiling system.
At first I wanted to gut the interior, but it wouldn't save all that much weight. I plan to simply add a cage and then do whatever for my guages and stuff. Also would be doing some frame braces for obvious purposes.
Not sure what to do about shifting. I guess I could rig up the linkage for the TH-400 to where I could use a floor (or console, for that matter) shifter, right?
Another thing that I have yet to look into is the rear end. Doing a Ford 9" or something is a lot of work, especially with the IRS these cars have. I do know that the '94+ models had a stronger rear end that was also a posi. I would like to see about swapping one of these in. Cheap and easy. It might break, but I would think the tires would slip before that if I can get it to work. I'm not going to be running slicks or anything.
These cars weigh about 2600 lbs. That's one hell of a power to weight ratio.
Basically my reasons for this build boil down to something very simple. I want something cheap, fast, and fun. I gotta have an RWD car to mess around with. I could start my Charger project, but that would take such a long time and so much money. If I can build something fast on the cheap to mess around with, why not?
for me atleast, it woudln't be a daily driver, more like a fun sports car....
I would *want* a DOHC 4 or 6 cylinders....
simply because I would want to bang thru the gears, rev it up high etc... I don't like DOHC for daily driver use and stuff, but as a sports car when you are mostly driving it fast, its a great thing.... so I personally think I would stick with what it had, and work with that.
They are very different then a muscle car... muscle car is pure power... sports cars have traditonally been modest, even underpowered cars made for the driver... perfect handlings, nice 4/5/6 speed manual transmission... made to connect the driver with the car to the road....
bolting a 500 beast into it, hardly seeing above 5,000RPM using the 3-speed auto TH400... just seems to ruin what the car would be. Yes, it'll be fast, and it would beat other similar cars in a drag race... but personally, it isn't what I would want... While I prefer large American cars with large V8's, I do have a slight desire for a small sports car and such, so if I did, I would want to keep it true to its roots...
The new Pontiac Solstice/Saturn Sky REALLY got my attention... I got to sit in a Solstice, manual, convertible... such an amazing car, the lady just bought it and loves it.

Yeah I agree with what Rick was saying...
The 240SX was designed to be a fun, zingy, little canyon cruiser that could seat 4 in a pinch.
Putting a 500cid V8 into it will make it very very fast.... in a straight line, but it would be completely unbalanced. These cars never had much low end torque when new, and I think putting a motor that ripples out atleast 360 lb/ft (a 205 lb/ft increase) would kind of ruin the car's main intent.
It's kind of like putting really stiff shocks or springs on a '95 FWB. Sure, It'll handle better, but was a '95 FWB meant to handle good? No.
Now I'm not trying to kill your idea, but this is what I have come up with.
It will be a very fast car if you can get that power to the ground
I understand, but I think you guys got me wrong. Sports cars are fun, sure. However, I don't want a Nissan. I don't like the 240sx. I am not going to have one as my daily driver, or even as my weekly driver. I like the Cad 500, I like power. I want something that is powerful and RWD to take out and mess around with. Smoke some tires, tear up the streets, maybe take to the track every once in a while, not something to drive around town to the grocery store.
