Has anyone been following the progress of these engines?

 

The aftermarket is starting to really grow for this engine.

 

"divlac57" is the guy who has been spearheading a lot of this

 

Anyone else watching any of this come about??

I have been. And for those searching its nivlac57 on YouTube. I have a 84 maxima wagon and I measurd once when I had my engine out and it was to close to try. I am interested in yhe 5 cylinder though as it would fit under my hood.

Yep.  the 5 cylinder hasn't caught up yet to the six.  the six cylinder 4200 is REALLY taking off now.  I have one I am putting together, and possibly put into another Z at some point.  It will be turbocharged, etc.  you start with 291 horsepower and 270+ torque, and then go up from there.  weight is 350 lbs.  They are a beast.

So I went ahead and bought one off of eBay and it showed up the other day.  It is a 2006, which is the 2nd of 3 variants.  It has larger ports and larger valves than the 2002-2005 models.  I have ordered a few of the high dollar pieces needed so far, my T shaped oil pan made by Forever Fabrication has arrived and I have it in silver engine enamel, within a few days my turbo header from the same shop will be here and I am awaiting the intake flange, runners from DMZ and plenum from eBay I will use to put together and have welded, then have the welds sanded smooth and either polished or powder coated.  I picked up another S30 engine crossmember which I will use, strapped tot eh bottom of the engine and measured from my Z car to fashion the motor mounts.   An Aisin AR5 5 speed is also on the way, and my Turbo is here, I ordered a T76 with T4 flange off of eBay, along with a Tial knockoff external wastegate. A chromoly 17.1 lbs flywheel from Atlas Industries is on order.   Cool stuff!
