The Motordyne MREV2 Iso Thermal! A universal stealth mod for use on any 350Z, G35, M35 and FX 35. When used with or without a spacer or aftermarket plenum, this modified lower collector will make substantial power gains.
Multiple independent test show when used with a 5/16" spacer on the REVUP engine, the combination will add a "minimum" of 15+ HP and 18+ TQ in the upper midrange. Many independent MREV REVUP tests have dynod in excess of 20HP and 30 TQ in the upper midrange and with high RPM peak power increased by 3-5 HP.
On the road course or drag strip this lower collector adds substantial HP and TQ. No other normally aspirated VQ modification provides as much gains as MREV2!
