were back LOL throttle body zs

I'm curious to know how this is running?
That's an airbox which replaces the OE inlet manifold, still looks to be running on the stock 180 throttle body so not an ITB set-up per say.

interesting point, its basically a plenum with no vis....which kind of makes you think it will lose all its torque...but still a great project and it will be very interesting to see the reality of the roller graph. Will answer a lot of questions.

think it might lose a bit a torque but may gain this back due to the way it picks up the rev range
the magic graph shows all

yes i agree, might lose low down but if you gain some back up the top then grins all round

is the need of a correctly fitting throttle body holding it up then, it seemed to be running ok in them old videos

I cant see a bigger throttle body helping it to make more power tbh but you never know till you try.
Hope your soon enjoying it anyway.

whats the size of the inlet on the plenum?

not sure drew

i think there are two options on the neck ???

ahh nice, hadnt seen the extendy piece before. you thought about doing a 90dgr to replace that, might make fitting the TB easier?

we have tryed a zr and a zs TB and we have been told theres no or little difference between the two

i just measured my zs TB at 55mm but its fookin long. if you cant fit that in id look at a T series TB @56mm.

toca tb sounds good but tbh its more money for little gain imo.
