I am recently looking a 91 CRX. because of huge demand and lack of supply, I have only found a few people selling their CRX, but they are all DX. I wanna buy a Si, but I can't wait any longer, so DX may be my choice. I wanna know the difference between a Si and DX, assume they are all stock. Thanks for the help.

 

dx = dpfi
si = mpfi

 

Thanks for the reply. So they use same suspension, engine and transmission? Then it is possible to convert the fuel injection on DX into Si right?

 

diff. engine and tranny. same suspension, yas you can convert it, or just swap a b16 into it. rywire can make you a plug and play harness and then its pretty much drop in.

 

theres alot of differences between the 2 models

si: engine,tranny,mpfi,wheels,rear disk, rear sway,door panels,sunroof,seats,

 

This has been covered several times. Here are to links for you first is the FAQ second is the link for the differences.
