Ok...

My housemate's 87 crx si got totalled (story later) from behind, and everything from the doors up is fine. He's looking for another CRX, and he found a really good price on an 87 CRX DX.

What parts would need to be swapped into the DX to make his Si engine run in that car? Obviously the ECU would go in, but can the wire harness be plugged in without tons of custom wiring?

Also, is the DX fuel pump/fuel line capable of supplying enough fuel to run a stock 87 CRX Si engine? All answers appreciated. Thanks!!

Oh, and also, is the suspension in the Si the same as the DX? thanks!!

im not an expert but i think it just pulls and swaps.... shouldnt be too hard (for a swap)

suspension i believe is better in Si but again, im not expert, im pretty new to CRX's in fact

Well, I know for one that the fuel lines and pump need to be swapped, and the gas tank is supposed to be different between the carb'd models and the Si. Most of the electronics need to be swapped. It would probably be a pain in the a*s to do, but if you want to try it, go for it.

Is there a dual to multiport swap in the 87s?

Kai

No DPFI in 3rd gen civics/ 1st gen CRXs... only carburators in the Base/DX/LX/HF's and multiport FI in the Si's and wagons.

Gasoline Fumes

The Wagons were carbureted. Only the '85-'87 CRX Si and the '86-'87 Civic Si were fuel injected.

I agree with it being too much work to go from a carb to FI, that is why I sold my 1500S and got my Si. And to keep the 1500S look I swaped the lights and wing. I just have a sunroof now.

Kai

I thought the wagon ran the 1500Si FI engine? Does it use the 1500S carb'd engine?

Gasoline Fumes

Yeah, it uses the 1500 EW1 from the 1500S, CRX DX, Sedan, etc.

thanks guys Sounds to me like going DX to Si for the 1stgen is quite a bit more than just a driveway swap. Sounds like Russ (housemate) gets a DX, or an Si.
