does anyone know if the acura version of the 2.4 has the same belt set-up as my honda 2.4? (basically will it work on my 2.4)

seems like i read that the acuras have more valves because the v-tech on acuras engage a second set of intake and exhaust valves... does this make the belt setup any different?

woops. i tend to forget to check that box before i post.
i emailed mike at unorthodox. here's his reply:

We have had a pulley set available for some time now. It’s the same as the rsx type s kit. Part # 04.06.022.02.

mike

$348.91 for underdrive kit. theres no oem size kit.
thats clears it up for me, and maybe someone else too.

i looked up the weight of these compared to stock, for a 02-05 tsx 2.4l 16v. the differences are pretty cool.

The pulleys are great, but without I/H/E you can't rev up that fast to take advantage of them. They'll help some by reducing parasitic inertial drag, but their effect is noticed as you run higher rpms. Without the I/H/E, your rev moves slower so your avg. rpm is lower. I'd look into headers if I were you.
