i agree for the most part with klunkemonger...I just wanted to say that the D series motor is a SOHC motor not DOHC Also tell him to upgrade the valvetrain depending on what cam he gets and to get a cam gear to tune itLuDeSi_93 said:My friend has a 98 EX with the D motor in it and is building up the motor, he cant do swap, anyways... What are the best pistons to put in? he is also getting a port and polish and new cams... so get back to me soon thanks..
yes the stock valvetrain is good enough for certain cams. Also what i didn't tell you lude that is if your friend runs very high compression that he will want to build his internals.klungemonger said:Yeah, I forgot about springs/retainers, but it depends on which cam he gets. I've heard the stock valvetrain is good for way up in the 7k rpm range if you get teh rev limiter removed.
So if you go all-motor with very high c/r you will need to get ecu tuned anyways so while they're in there they'll take out the speed/rev limiters.
