Thanks
I found a junk car that has it and I want to do it
Question is what is it do I need.
I know the basics but I would like to know everything of what I would need
thanks
DO i need the distributor or can i use my old one
do I need the ecu?
thanks

 

your going to need a si ecu,si disturabator,mpfi intake manifold,with injectors,resistor box

 

The thing isn't the dx and si dizzy the same?

 

no! the Si distro has the cylinder position sensor in it to sequentially fire the individual injectors at the right moment.

i'm sure that's what you call it ?

anyways the dx distro doesn't.

 

damn that sucks
the dizzy was already taken
how much should i pay for everything other than the dizzy?

 

HF distributer will work also if u can find one.....for the si ecu intake manifold and the wiring on the manifold is key also for the plugs and such i would say 150 if ur lucky if not ur gonna pay at a salvage yard in NJ 250 is a pretty fair price for an intake tb and injusters fuel rail and resister box but low ball em and see what happens just bring some extra cash....unless its a u pull it yard then ull pay about 150 for it all

 

thanks
i am gonna go there on monday see what i can pull out

 

I'll post an people will reply....

I think you need the following:

si distributor
si wiriing harnes w/ resistor box
complete si intake mainifold including throttle body and tps
si ECU

 

You dont need the Si wire harness its easier to use the existing DX harness and modify it to work there are plenty of topics covering the DPFI to MPFI swap so if you search in recent or archived topics you will come up with plenty of topics concerning this.....But you will want the wires that go from the injector resistor box to the injectors just so you dont have to worry about wireing up something else but if you cant get its not that big of a deal to run those wires as well.......

 

the si harness is still needed for the injecter, distributer, TPS, resister, and any thing else i forgot the plugs are needed so if u dont pull the part make sure u get the plugs with ample wiring off each plug ....u will also need to get an inatake manifold gasket from honda (recomended) a new distributer cap and rotor unless ur old one from ur dx is new....and the si fuel line is needed from the fuel filter to the fuel rail and the piece that holds it to the fuel rail its called a pulse dampner but its just a platic looking thing with a bolt to hold the fuel line in place. and if u are creative u can still use the dx throtle cable but the si one will work better i am still using the dx one and it works fine....u can upgrade to a y8 intake manifold and throtle body if u so choose it will work the same but u will need the fuel rail and eacv (on the back of the manifold) and ull need a iats(itake air temp sensor since its built into the intake not the manifold ull need to rig it up somewhere
