These bad boys turned up this week from the States - 62mm billet throttle bodies designed and manufactured by Robert Bastian.

They are fully CNC machined from billet aluminium and are beautifully made. They have proper shaft seals (no leaks under boost)

and the butterflies are a perfect fit when closed. They need the return springs and stops transferred from OEM throttle bodies and

the intake manifold will need porting to the larger 62mm bore. They will be installed along with AshSpec SMICs and 2.5" IC pipe

work in due course.

By way of illustration, this photo shows another car with the 62mm throttle bodies fitted (along with AshSpec IC pipe work):

 

As @AndrewG stated, I persuaded Robert Bastian to run a batch, after months of getting enought interest / commitment for a group by, and all were sold.

However, these do come up for sale from time to time. I remember seeing a set for sale on Ebay a while ago for $1000.

I do have a set fully assembled, which are reserved for a 300zx member. If he changes his mind, then these will be up for grabs, I'll post on this site.
