CA vs. KA

[Ryu0214]

hey everybody, new to forums and i want to get started on a 240 coupe project but i really dont know which engine to start with
i want to know if a CA18DE is better or a KA24DE
Take in mind these facts im going to do:
-rebiuld engine
-possible port and polish
-etc
-NA only!
thanks for your feed back
im looking for an engine that has better than average horses and is fast

KA More Displacement
US parts
Engine is in the car already
If not then you can get a newer engine
DONE!!

If you're going NA, the KA is the ONLY way to go. Well maybe not the ONLY way. I'd like to see a V12 in an S-Chassis, but I'm sick like that.

The CA NEEDS the boost. Without it, it has nothing to give. Well, not in an S chassis, anyway.
If you're naturally aspirated, you either need lots of torque (KA), or lots of revs. The CA engine unfortunately has neither.
Read themadscientist's opinion AND experience on the matter, here, from not that long ago:

An NA CA in a dune buggy, sure. In a heavy a** S shell? There are easier ways to go slow.

Riding around with TMS being one of them...

[themadscientist]

I'm always faster than you expect.

[float_6969]

That's what she said...

[themadscientist]

No she said, hurry up Ryan will be over any minute!

[float_6969]

Damnit! I knew you've have a good one. I almost didn't post that.

[themadscientist]

And what did you learn?

[sjbsuperman1425]

you two fight like a married couple..

[Ryu0214]

WOW thanks guys
hmmm, it seems that the KA is a better choice
now other questions i have:
1. how many MPGs will i have(am i gonna be at the pump constantly?)
2.how well a port and polish will effect the output of the KA
3.is there an aftermarket ECU system for the KA (like the Honda Hondata?)

thanks a lot

[float_6969]

Those are questions better posted in the KA section.
