Hey everyone... first post on the forums, but I've known about the site for some time and I've been searching around and picking at posts for the past week or so. Been contemplating an S13 or S14 Silvia, and have pretty much decided on doing up an S13 in the next year or two.
I've done my research on the KA24DE, E, SR20DET, and CA18DET ... and based on everything I've seen I've decided to go with either the CA18 or the KA24... -leaning heavily on the KA24 work for various reasons...the top of which is off-boost drivability... so here's my question (inquiry, really)
I know that the 89-90 has the KA24E, and 91+ had the KA24DEFrom what I've read, for NA applications the SOHC E would be the better choice ... but I am not after an all-motor 240.My question that I have searched adamantly for (and bonk me if I missed it) is:
Are any noteworthy differences between the E and DE that might make one better than the other for a turbo application?
This stems somewhat from a small debate a friend of mine have had about 4 valve heads versus 2 valve heads, flowrate and pressure with having additional vales even though they are smaller, fuel economy and flow, etc and so forth.
I've worked a bit with my turbo Ford vehicle (XR4Ti; Garrett T3-equipped 2.3L SOHC Pinto engine WOOT!) and obviously it puts out a great deal of power so it doesn't "bother" me if the E end up being the better choice. Just that much less internal resistance in another cam, additional valves, etc.
Any feeback and bouncing of ideas with discussion is appreciated.
Thanks guys
