Use the EP charger and 3.8 SC pulley with a modded OEM belt tensioner and a k24z (Newer Accord or "skeletor") crank pulley. Swap out your MAP sensor with an upgraded sensor of your choice. You will be guaranteed 10psi at 8krpm on your k20a... and it will run just fine on 92 octane fuel after tuning.

Anything smaller than a 3.8 SC pulley with the JRSC tensioner WILL slip at high RPM's as the belt stretches.

If you want a good selection of belt size/length, you need to look at the 8-10 rib belts... and cut off the extra ribs you do not need.

If you do decide to go the above route... i have a Hondata KPro KAL that works as a solid basemap id be willing to pass on (VTEC switchpoint, not window, at 4500rpm).
