ka24de or sr20det

i read an old post last night where a few people argued over witch engine was better for drag racing, the ka24de w/turbo or the sr20det. I have no intrest in drifting i just want a car that is quick off the line with minimal mods. i have no intrest to run10 second passes, 12's or 13's would be better suited for me, but witch would be better on the straight shot in a 240sx.

100 lbs is a lot of weight difference between two motors. Especially in a front engine/rear drive configuration. If there really is a 100 lb difference (I really don't know if there is), then that would seal the deal for me.

the reason i ask is because i am going to get a 240sx. if the ka is better for drag racing i will just have the engine re-built, but if the sr is better than i will just by a knew one. buddy i work with, who builds his own race cars, mopor, told me i should do the re-build myself, anyone know how difficult it is. and what would be more costly, paying someone to rebuild the motor or buying an sr and doing a swap.

The SR is certainly the better motor of the two but if all you're looking for is that you'd be fine turboing the KA.

odds are the weight difference is more like 50lbs, motor to motor. the various addons that come with having a turbo system adds to the weight consideration. so odds are the sr20det with the stuff that goes with it will weight the same as the ka24de with all of its crap.

u should stick with the KA. ppl are doing pretty marvelous things with that engine, and its actually more reliable than wat many ppl think. its heavier due to the iron block vs aluminum block, but i would trust the iron block more (harder material is usually harder to break). stick with it. it costs the same to turbo the KA as to swap in an SR (and i think prices have gone up on the swap)

We don't get the KA in Australia, only the SR. But let me tell you the SR is one of the best 4 bangers around and would be a hard engine to top.....
