SR20 90mm throttle bodies - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I just picked up an aftermarket intake manifold/plenum for my non-vvt sr20.

It has a monster 90mm intake. I didnt get a throttle body with it so have been looking into them. Im wondering if a 90mm TB will be too much for my setup and kill throttle response and lag/torque etc. Car will be used drifting on track.

Spec is as follows:

Trust TD06-l2 20g turbo 8cm exh.
Tomei 260 procams
Forged bottom end
Around 1.4 bar boost

Would i be better off fitting a new flange and using a 70mm throttle body? Or will 90mm be ok?

Thanks.

A 90mm throttle body would be titties on your setup. Better throttle response and better gas mileage and more power etc.

I have a q45 non ecs throttle body with TPS pigtails which i believe is what that manifold was intended for. PM for a good price =)
