i have a 88 crx dx and i just bought a 92-95 civic intake so i wanna do the dpfi-mpfi swap, but i have no clue how to do it, is the wiring changes the same as the 88-91 manifold swap? because i found a whole **** load of info on that but i dont know if it is the same swap as the 92 - 95 mpfi?
what ecu and distributor do i use to run the 92-95 intake?
please help me on this thannks

 

yes, the wiring is the same at 88-91. you need to use a 91 SI ECU and distributor.

 

so the wiring is the exact same when using the 92-95 intake?
and the 91 crx si ecu and distributor will run the 92-95 intake?

 

please help

 

Let me get this straight. You want to make your 1.5L DPFI to a MPFI just so you can use a 92-95 intake? Please don't tell me your doing it because of that.

Intake = a couple of horse power.
MPFI = a couple of hp
both = a big waste of money, time, work.

Save your money and do an engine swap. Can do a ZC for around 900 bucks.

 

That is WRONG!! the distibutor is different, and the wiring to the injectors is different.

 

the 92-95 injectors wont work. EVERYTHING else off the 92-95 mpfi(intake manifold, TB, TPS, fuel rail, fuel regulator,etc) WILL WORK. youll need to use 91 SI injectors, distributor, ecu, and injector resistor box. others will work but i recommend those. the mpfi wiring for 88-91 is the same as the 92-95. you will need to rewire the SI distributor as the DX dist does not have the crank position sensor on it but the SI does. dont listen to anyone that disagrees with ANYTHING ive said, as i have done it personally on my 90 DX hatch.

i alredy have the 92-95 intake manifold for the mpfi, i have dpfi and i want mpfi and i got the intake manifold for chep thats why im doing it i just wnat to know what distributor and ecu i need to use to make the 92-95 manifold work for mpfi
thnaks

 

i recommend the 91 SI distributor and ECU.

 

ok thanks alot crv-vtec dx so let me get this stright all i need to do is get is
91 si injectors
91 si distributor
91 si ecu
91 si injector resistor box
after i get all that i just follow these directions dx to mpfi directions
also what do i have to chang in the distrbutor?
thanks for you help

 

opps sorry i meant these dirrections http://honda-acura.rely.net/zerothread?id=111104

 

also later on i wnat to put i 92-95 vtec head on, will all this wir up fine if i get a vtec contoler
also how much are 91 si distrubutors ?

 

i dont mean to be a dick but how many times are you going to post about the same thing. and how many times are people going to have to tell you the same answer? that wiring will work. those are the parts you need. do a search read my posts. i am doing the same swap right now but i have the 88-91 parts. i posted a couple of weeks ago asking about the 92-92 parts. i am sorry just tired of seeing you posting a new thread every couple of days asking the same question.

 

1.yes thats all youll need. follow the instructions on the link you posted. wires c1 and c2 are the ones that get wired to the dist.

2.to do the sohc vtec swap, youll need the completed 92-95 head and external vtec controller, and thats ALL. everything else wires up the same. a 91 SI distibutor is like $50 from the junk yard.

 

the thing is im getting so much **** and its hard to put it all together cause some people tell it will work and others tell me it wont all i want is complete info so if u could give that to me that would be great
thanks insted of gettinmg a bunch of mixed informatiuon

 

you got EVERYTHING you need to know in this post to do it. that said, GO DO IT and have fun.

 

Oh whoops. I thought he was talking about a DPFI to MPFI, and not the Differences of 92-95 MPFI and 88-91 MPFI.

Sorry if i ruffled any feathers.

My main question remains. WHY?????????????????????????????????
The results will not be worth the work, but maybe you guys just get off on that!?

ur a schmuck mpfi is good for more than a couple of hp. in fact in a 91 hf we ran 15.4 with a dx motor and dx trans so dont talk **** on something u have no knowledge of. the mpfi is a cheap way to make hp. teh zc is a waste in my opinion.u spend $ on a motor with 25 hp more than a stock si. when u could save up your alowance for a few more months, and get a b16. its a swap ur gonna want to do anyway since ur gonna want to go faster trust me.

 

what do i need to change on the distrbutor though???

 

i agree with jdmb18hatch

everyone underestimates the mpfi swap. i beat gsr's with i/h/e with my 90 dx hb.

 

follow the instructions on the link you posted. where it says:

Connect C1 to blue/green wire on cylinder position sensor plug.
Connect C2 to blue/yellow wire on cylinder position sensor plug.

those wires connect to the SI distributor. just follow the colors on the wires.

ok thnaks alot guys ive got it figered out now sorry if i was a pain to you guys
thanks for your help
