1.5L throttle body

[joshknobel]

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
