I'm wondering if a conversion is possible, not a complete conversion per se, but the dual throttle bodies mainly. I'm not completely familiar with the HR, but could you replace the DE plenum with an HR, add a second TB, play some fancy footwork with the linkages and sensors and have dual intake?

 

Not sure how you would handle the ecu for 1 more TB for the drive by wire and how to compensate for another maf with undoubtly a diff scaling.

 

um....no....Get a sfr intake manifold or aps tt--then you'll have dual intake.

 

kinda was of money to do VQ35DE to Vq35HR.. It would be better to TT your car and save money..
