newbie question
 

I have a 91 CRX 5-spd with a DX 1.5. What keeps the SI cold air intakes for fitting this car? Thanks

Might be the position of the throttle body. Do you have pics of the air filter box and everything that isn't needed for the intake out? Does the throttle body stick sideways or straight up in the air like the D15B's and D17A's? :)

I'm guess you hit the nail on the head eXNBP.
lets see some engine shots of the two.

The fitment is probably different between the MPFI in the SI and the DPFI in the DX (I'm assuming that the 91 DX continued to have Dual Point Fuel Injection). My 89 DX has the DPFI and the connector for the intake looks much different than my dad's HF, with MPFI.

That's it. It's got the dual point injection. I couldn't get pics for everyone else sorry.

Thanks

they have different intake manifolds, the DX's intake looks more like that of the HF but the HF has Multiport where as the DX has the Dual point TBI(throttle body injection). IF it was an Hf you could put and Si intake on it but not on a DX....but you can swap just about anything into that car you'd like to :)
