1.5L throttle body

Alright, my brother has a 90 CRX with 4-2-1 headers, Test Pipe, Tanabe Racing Medalion Cat-back, Cold Air Intake, Lots of Ignition upgrades and a Zex NOS kit. I'm thinking that he needs to move up to a little bigger throttle body to get the most out of his upgrades, however i don't know where to get one and what fits. I was wondering if any other larger stock honda throttle bodies will work for the 1.5L without modifying the intake manifold. Any help will be greatly appretiated! :)

I'm pretty sure that the Si throttle body will work on any d-series motor besides the dx cause of its manifold. Does he have an HF? I can probably get you a throttle body if he needs it.

oh, he has the DX... but he was looking at doing the multi port fuel injection swap. So i he'd need the computer and manifold too.

why would anyone want to put nitrous on a DX manifold LOLOL
