where do i find if my car is a SI or DX
thanks!

dx is 4 door sl is 2 door.....

dx is 4 door sl is 2 door..... Thank you for clearing that out

Dx can be 2 door too. Where is the redline on the tach?

wouldnt the biggest distinction be if its mpfi its SI if its dual prt fi or carbed its dx

Yeah, that's true too.

Carlos916,

All of the above information is wrong!


Here are the real differences:

An SI will have a fuel injected motor, a motorized sunroof, an aluminum valve cover, a rear wiper and a soft foam rear spolier.

A DX will have a carbureted motor and a stamped steel valve cover.

Since you have an '87 CRX (I looked in your profile) it could also be an HF model. An HF will have a carbureted motor, aluminum rear brake drums and a black plastic valve cover.

A glass sunroof and a plastic spoiler were options on the HF and DX models.

There are other differences but these are the most obvious, and over time some of the parts on your car may have been replaced with parts from other models.

my car have a soft spoiler. It doestn't have an sunroof and a back wiper.

my car have a soft spoiler. It doestn't have an sunroof and a back wiper.

Then it's either a DX or an HF, and someone added the spoiler.

All SI models came with a motorized sunroof and a rear wiper, there were no exceptions.

lxndr you save they day again lol and i wast completely wrong with what i said just a lil but thanks for clearing it all up i had been wandering how to distinguish between them myself
