this motor is obviously built for high rpm use, which is necessary for its claimed 340hp output. obviously this is for a race car, but it gives you a bit of an idea of what you need to go through to build huge N/A numbers out of these.

Especially because this is a carb'd SOHC.
Ok guys. I can't be too specific here but I'll give a few specs
1. Rebello DIDN'T build this engine. Dave Auerbach did.
2. SOHC KA's don't like more than 7800rpm's They tend to turn the rockers into "dust"
3. Compression ratio on this engine is 14.38 to 1
4. 44mm Mikuni carbs with 34mm chokes on nissan comp manifolds
5. Cam is .620 lift (can't tell you duration, sorry)
6. Cyl head, manifolds and exhaust have MANY hours of work
7. Torque is 231@5200 and HP is 281@7500 at the flywheel
8. Rebuild interval is 1000 miles (running between 5200 and 7800 rev range)
9. You absolutly CAN run this engine on the street. When I drive it through the paddock to the false grid, it drives like puppy! At 7800rpm's it's a bit like !

When we dynod the engine with 50mm Mikuni's and 44mm chokes we got 341HP at 8000rpm's. We figured that rebuild intervals would be about 400-500 miles at that HP and I decided to run the car in GT3 (restricted to 34mm chokes and 281hp) instead of GT2 (44mm chokes and 341hp) to try and cut down cost a bit.
If you want an engine like this,...Plan on spending around $18,000
Or you could buy the car and ALL my spares (2 engines,2 transmissions,2 rear axle assemblies and a TON of other stuff) for $35,000 TODAY

dont suppose anyone say the 120Y at the prospect datsun day - 2.4 L series with KA24de head and quad throttle bodies. Also had IRS rear end.
