Well my new plenum and bigger 240xs throttle bodies came today

 

Not the best job in the world but easily polished up again and a couple of things tidied up :)

 

but compared to standard ones there much bigger :) i took a picture of the silicon which easily went over the old throttles and on my new ones they just slide inside them :bow:

 

 

So hoping to allow some more air into the engine and make a little extra power ;)

 

 

 

Should also increase the throttle response and make it a little easier to drive :)

Wow - nice one Mike, I never realised how small each standard 300ZX TB is til I noticed some of the other Nissan ones, where there's only one obviosuly. A good upgrade :cool: Presume the plenum is port matched to the TBs?

yep the plenum is ported to match the throttles :)
