Multi Point over Duel Point

[Crx Guy]

Ok so simple question maybe not so simple answer.
I would like to know what the big difference is between Duel point fuel injection and Multi point fuel injection. I am switching from Duel to Multi once I get my new motor put in and I was just wondering what I should feel or any thing like that. Thx Guys

dual point is throttle body injection with two injectors in the TB that fire on every round, simple and reliable. multipoint has one injector placed before each intake valve for a total of 4 and inject fuel when each cylinder needs it.. and in honda's multi provide more power. multipoint requires a crank angle sensor.

so yes in other words it does alot more then dpfi its just ment for cheap travel and by no means does it come close to performance...dual point to multi point was the first swap i did to my dx..then after that i did the mini-me swap with a sohc vtec head from a 95 si...but yes it is a pretty big difference, well at least i noticed....an by the way what are you droppin' in ?

get back to us

I am droping a Late B16A into my CRX.... now I realize now that even when I do switch to multi point I wont feel a difference cause my engine will have about 3 times more HP so I will still be getting use to it hehe
What all do I need for duel point multi point switch ?

You can have the biggest engine in the world, and if you still had dual point injection it would still run liek shit, if your gonna have the body your gotta have the brains' haha but no really dpfi to mpfi is no biggie i did it in liek a hour, does the engine that your getting have the intake manifold an what-not casue is it does your can take all that an hook her up to the ecu you need enyways..but if your jus putting mpfi into your crx right now then you need:

88-91 si intake:
88-91 resistor box from si
88-91 Ecu from si
88-91 Distributor
and the black u looking hose on the dizzy side of the intake mani,it hooks your intake to your head you'll see it

and some extra wires as you will need to extend the trottle position sensor about nine inches, and your EACV about 5 inches.

you can do a search on the how-to and if you need these parts i have everything an will sell them to you for not to much..that is if you cant find them! and if you cant find the how-to i'll scan the one i made and send it to you through e-mail ok...

talk to you then!
