I am getting ready to start my dpfi to mpfi swap over spring break. I have the ecu and manifold with all the sensors. I still need a distributor but are there any other parts you guys would recomend while i am working on this? Is there anything i should replace now? Any suggestions that are helpful would be nice. Also is there any problems that you guys ran into that i should look out for while i am working on this?

 

you also need fuel injector resistor box and solder all the connections and have helms etm manual handy

 

Im also doing a MPFI swap for one of my friends, i was wondering if anyone who has done this before can tell me exactly which plugs i will need to change.

 

ur gonna need teh fuel injecter plugs teh distributer plugs, the injecter resister box plug...
u should change the head teh dx has a smaller cam grind than the si witch will make more power get a 92-95 si head gasket its thinner and metal=higher compresion and more hp im me if u have any questions about the swap its really easy

 

JDMB18HATCH thanks for your help, is it cool if i give you an email if i run into any problems with the swap? Thanks again bro.

 

no problem i like to help

 

Where can i get the plugs? The local junkyards dont have any Si's. Sorry i have the resistor box too.

 

do u have integras? accords? anything with mpfi will work for the plugs... mostly the 92 and up wont work anything below.

 

so i ca use the distributor plugs and such of older tegs and accords?

 

Can i get all the plugs from and hf? Do i need different plugs for the ecu?

 

hf will work fine and the ecu will plug right in u need to do some wiring at the ecu a few wires need to be cut and some added like 4 or 5 i forget right now tired

 

That is good because there is an hf at my local junkyard. I was pretty sure it was 4 wire to add and then some repinning. Now i just need a new intake manifold gasket and the plugs. Anything else?

 

get teh distributer off the HF its the same as a si

 

the hf is the same as the si. damn i wish i wouls have known that. thanks i am going to call them up.
