Do a bit more research before you say stuff like that. Just cuz your read it in SCC or another moronic mag doenst mean its gods word. The KA started its life under the hood of a 240, not a truck. The KA is a great motor, I would pick it over most any honda motor out there. Its got potential, even more so than the SR, which has been put up on a high horse just because its JDM y0! Both are good motors though, I wont deny either one of there good or bad points, but never rip on the KA because of what some un-educated fools have put into print.
I agree. People always say 'truck motor', to me there is no difference, just because it's an iron engine doesn't mean anything to me. One of the latest SCC had a KA belting out 400+ hp... it can probably take more too!
Just cuz a motor was in a truck doesn't mean it's a truck motor. (it's a motor).

my 2 cents.
peace.
In my opinion anyway, the SR is a far superior motor. The cylinder head flows better and the piston speed is lower. The SR is much lighter. The KA also has head sealing problems in the low 20 psi range.
Because of the piston speed issues, the KA has a penchant to throw rods at much over 7k rpm. In fact even well built KA's with aftermarket rods still have issues with bottom end failure above 7k rmp due to harmonics. Spectacular failures at that as well, like the lower part of the block cracking in half.
Even the best built KA's that I have seen like Chris Mays, Simon Kim or Kenji Sumino are only good for the mid 400's in power. That's peanuts for a good SR20DE. I have gotten over 400 hp from bone stock bottom end SR's before, can even come close to that with a KA.
The KA is a pretty good motor though, just not better than the SR.
as far as revs go, who cares it it doesnt rev much higher then 7k, the power band is below that anyways. You cant compare revs with the two engines, they are built differently; bore/stroke wise. Thats like ripping on the SR cuz the CA will out rev it. And as far at cast iron block goes, I see that as a good thing, stronger and no cylinder wall flex. There are a few KAs out there putting 350~ to the wheels on stock internals, and they are daily driven cars. If it came down to it I would choose, in this order; KA24DE-T......CA18DET........SR20DET. But then there is also the RB.

The damage isn't that bad. Front bumper, hood, driver's side fender, foglights, airbags, and one of those slanted headlights or are they projector lights? No damage to the engine..still able to drive it. Luckily he has full coverage.
what year is his S14? If it's the earlier model, this is the great chance to go 97'~98' front end conversion (w/ projectors). Sorry about going off topic... but I had to say..

It's a dark green 97 240sx. He did ask me about upgrades about his car. I don't really know too much about the 240s both performance and cosmetic, but it's really a nice car or it was.
hey morepower.......iirc the SR is 70lbs lighter than the KA, or maybe even less. it's not really an issue. and why would you try and make a KA rev past 7k anyway? that's like trying to make rosie o'donnel suck dick, she wasn't made to do it, so why make her?

I like the points you made. Wasn't the KA in the Stanza before it was in the 240?
