now that we are at a site with good working archives (I assume), I wanted to repost this question for the V6 N/A owners.

First, I don't own my 3.8 N/A anymore. I would have probably kept it, but it didn't have the power I needed. After letting it go, I began to read more about the mustang boys converting their 89-98 3.8L's to the newer 99+ split port heads and intake.

Most of the info I retrieved was from the <A HREF="http://www.v6power.net" TARGET="_blank">http://www.v6power.net</a> message board. The most complicated part of the swap is modifying your fuel rail. You have to modify it since the 99+ heads have evenly spaced injectors where the 98 and earlier heads did not. Otherwise a lot of the swap is bolt on. From what I have seen and heard, the newer style heads and intake were good for taking your 145HP up to around 180-190 in stock form. Add some bolt on's from there and you're talking about a 200HP N/A v6 (and loosing your reason to sell your car for a faster one).

The 99+ make 190hp with a less agressive cam than the 98-down cars.
As soon As I get home sunday I will post all the Stock specs I have collected for 89-98, 99+, and 4.2L <IMG NAME="icon" SRC="http://images.zeroforum.com/smile/emwink.gif" BORDER="0">
