These two plots show a totally stock K2A2 RSX vs a highly modified K20A ITR. This is an indication of the power potential of the RSX type S K20A engine.
The ITR has
- JR Prototype header
- Hondata intake gasket
- Hondata K20A flash
- 45 HP gain at 5800 rpm and at peak RPM.
The K20A ITR engine also has a different intake manifold (stamped PRC) and 1/2 a point higher compression. Both ITR and RSX K20A2 heads have the same casting number - PRB. Neither intakes up to the valve seat have been ported.
