Street legal race car built off of a 1989 Nissan 240sx platform.
This car is powered by a 406 cuin (6.7L) Chevrolet V8 small block which makes 468bhp and 508ftlbs of torque in its current configuration. The motor was built for a broad power band with gobs of mid range torque. The motor puts near or over 400ftlbs to the wheels across all but the very top of the rpm range. The motor can turn 6800rpm and makes peak hp at around 5500rpm. With a slightly different cam the bhp could go well over 500bhp, but at a sacrifice in lower rpm torque. This is driven through a Muncie MC1 3 speed transmission from a 1969 Camero SS, followed through with Skyline diff and axels with 3.69 rear gears.
The car only weighs 2335lbs without driver. During the last time that lateral acceleration was logged the car saw a peak of 1.96g's on cold asphalt with slicks. On hot asphalt or concrete this number should be well over the 2 g mark.
The car was a trailered car with a salvage title that was reconfigured to be street legal. It has been built to the SCCA SOLO XP rules. The car is completely capable of running Fastest Time of Day at autocrosses with good driving, and will usually run around 5th out of 100 entries with so-so driving
Below is a list of modifications:

Wheels and tires:

Kirkey 16" layback seat in passengers position (could be moved to driver's side if driver needed seat larger that 14")
RCI harnesses (5 point on drivers side, 4 point on passenger's side)

The bad:
The cabin gets warmed by the engine. Good in the winter, bad in the summer.
Occasionally the starter will struggle to crank a hot motor, but I have always been able to get it to crank.
As listed above it will need rear street tires soon
It has a small oil leak coming from the rear of the intake manifold that likes to collect on top of the transmission (edit: I think that this is has now been resolved)

I am asking $10,900 or a reasonable offer for the car. NO joy rides. Call or text (text preferred) Josh at 843-367-9097 info I may consider a trade. Text me pictures, the worst that I can say is no. This car is crude, but it is nothing short of an experience to drive.

It's hard to sell a 240 that isn't crude for $10k. Just saying
