Still got the DISA on my m42 and it's in working order.
I took the stocker off and put the Ansa on myself ... cant' say I noticed the difference aside from sound.
Either way, like I said, the m42, overall seems to pull better up top, but I was just wondering about the low end.
John Firestone,
yeah, that would be kinda cool to have. VTEC just kicked in yo!
If you do decide to do it, let me know what you have it wired up to.
