Dual VVTi 2JZ

Hm...I'm really thinking about making one lol. I have a few extra 2JZ's sitting around, and soon I'm gonna be picking up a spare 2JZ-GTE VVTi engine. I'm thinking that it might be possible to modify the head and journals to convert the engine to have VVTi on both intake and exhaust side. Obviously this will require sacrificing one head by cutting it up to cannibalize the VVTi mechanism. Once I cut it out, I can weld it onto the other head and use the CNC machine to get everything down to spec afterwards.
As for tuning it, I have the AEM EMS which has plenty of extra output channels to control the extra VVTi solenoid.
Some of you guys might wonder why I'm going thru all this trouble. Well, if I go through with it...I'll be the only person in the world to have a Dual VVTi 2JZ engine![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
Obviously I'll be experimenting with all this, but my hope is to significantly boost low end torque and speed up the spool.
Plus I have a few extra engine heads sitting around so why not give it a shot...heh.
What do you guys think?

Actually VVTi is not a simple on/off system like Honda VTEC. The VVTI is what it is...variable valve timing. The AEM can drive the solenoid at intermediate and variable positions to allow a total variable timing adjustment of up to 30 degrees.
Either way, I gave up on this project since nobody in the world makes an aftermarket camshaft for the VVTi motor. Maybe in the future when someone does make a more aggressively profiled camshaft then I will pursue this project again. I plan to make around the 800-900hp mark eventually and stock cams simply will not allow that.
