Hello.. what are you guys talking about..?? Obviously you are all stuck in your ways.
A KA24DE, produces more HP stock (135.6hp @ 5300rpm, 150.6ft/lbs @ 4100rpm) than a stock L24 (107.9hp @ 5300rpm, 115.9ft/lbs @ 4000rpm). With no real change in shift points either. NOTE: All numbers are at the wheels. To get an estimate of crank HP numbers add 25%. Ratings from: http://www.datsuns.com/Tech/datsundyno.htm
So instead of losing anything with this 4 clyinder swap you would be adding about 20% more HP AND torque. :stupid:
Add to that it's a cheap motor and would lighten the car a bit in the front improving handling. Tons of 510 guys have done the swap from thier old motors. So plenty of info out there on the swap. Just because its a 4 cylinder doesn't make it weaker than a 6, especially when you compare a 70s technology motor with carbs verse a 90s one with port injection, dual cams and 16 valves per cylinder.
Anyway, you would want the one from a 240SX S13 or S14, or a Pathfinder. They also came in Altima, and some other cars, but the FWD motors are setup differently and dont work well. Although you could get the block and head from an Altima and the other parts from a 240SX. In case say you found a cheap 240SX with a blow motor.
Recommending he buy a generic grocery getter is lame.. with the lightness of the 240Z and the aerodynamics of it, I would think 30 MPG is easily doable with a KA24DE. With more power to boot... and whats so wrong with wanting a unique car thats fun to drive, but maybe a bit better on gas mileage ??? Not to mention easier to find parts for at a Pick-a-part (he is a college student afterall).
Jeez... lighten up guys... and BTW the Honda comment was totally uncalled for.
