One of my buddies has a 88' Si, he wants to take of his manifold and put on a new one. There's nothing wrong with the manifold. Here is were my quistion come in, I want to know if there is any way to put that manifold on my 91' DX? I know that the fuel enjection is defferent but all that will be replaced. Do i have to have a new ECU or is it just a crazy question???

What you are proposing is commonly known as an MPFI swap.

You will need the manifold with all of its attached sensors, fuel rail and injectors, the distributor and the ECU. You would also need the different throttle cable and injector resistor box.

You should be able to find more information with a search, but if not let us know.

Ok... I found this site but its for a civic does that matter? And is this to big of a thing to take on with limited knowlege??

That link doesn't work for me, but if it's talking about the MPFI swap on any 88-91 Civic, it'll be the same thing for your CRX.

If you can handle replacing the intake manifold, setting the timing and doing a bit of wiring, you can handle the MPFI swap.

that is the site i used when i did the conversion for the first time.. . . . just follow the instructions and you will be fine....

if you are comfortable with bolting on the intake and distributor and doing basic wiring then you should be fine if you follow the directions... . . .

add the Si cam if you can get one and you made a nice little power boost.. .

but it works just fine with the stock 1.5 cam as welll
