That is probably the highest horsepower KA24DE I've personally seen. Dyno-tested 178rwhp and 184lb-ft of torque. (That's equal to roughly 209bhp and 216lb-ft at a 17.3% assumed drivetrain parasitic loss) Here is the mod list:
11.0:1 JE pistons
Crower rods
Block bored .040 over
Polished and lightened crankshaft
All internals balanced
Fresh rebuild last year
Ported and polished cylinder head
Port-matched and extrude honed intake
Custom cams 228 duration 390 lift @ .050 lash
All new valves
Bored and polished throttle body
Injen intake with cai
Greddy header
Greddy exhaust with electric cutout installed after first convertor
Greddy radiator
Underdrive pulleys
Fidanza flywheel
New ACT clutch
New starter
New alternator
New water pump
370cc injectors
300zx fuel pump and filter upgrade
Two 10" Electric fans
The owner, ni*2*ss*4*an*0* at NICO, claims he has about $5,000 in the engine alone. Therefore, we must determine that naturally aspirated horsepower is expensive. However, it is dynoing more than a bone-stock early SR20DET... without any lag at all. This should tell you kids who want massive horsepower with a NA KA that it's simply not going to happen unless you pony up the dough. Expect similar results from your setups and I hope this cleared some things up for some people.
My take on this is that if one were to swap in a smaller, more square engine and make it rev higher, it could make more horsepower than the KA. Of course, who's going to swap a SR20DE in? If I had the dough and the mechanical wherewithal to do such a rare swap, I'd make sure to do stuff such as ITBs, a stand-alone EMS and extreme head work.
What was the point of this post? To show newbies that their NA 240SX won't make tons of power, but then again, that's not the point. We're not drag racers, we're drifters... sideways is all that matters. Learn what you can... I'll update this post with dyno runs with different mods so you all can see their effects.
