If the answer is yes, then I wouldn't bother. The d15z1 is so gutless it actually hurts mpg because you have to run it harder just to keep up with traffic. I honestly think a z6 or d15b is capable of just as good mileage. d15z1 + Si/EX tranny might be tolerable, but you'll still have to keep it slow on the highway. :/
ugh. You sound like me when I'm trying to get people to understand that they don't need a new computer because the one they have does what the need. My d15b vtec is fine. :hs:
Well, my tranny is starting to go. It's got the dreaded 3rd gear grind, but it's getting worse. Since it's an Si I guess I think I'm not liking the 5th gear @ 2700rpm doing 65. I think I've brought this up to Tony, but how many guys actually take the 5th gear from a dx/lx and through it in the Si tranny? This is a highway car and I'd like to take advantage.
