how much will everything cost to do the dx to Si axle changing???

K2e2vin · 08-11-2008, 02:11 AM

I wish I still had the axles and knuckles to compare. Sounds very off to me; I've had 2 sets of 88 CRX DX kncukles and a set of 88 Std knuckles laying side by side. I just threw them all away like a month ago though.

Price would depend. You can probably get DX/Si knuckles for like $50 from the junkyard or some third party. Then you'd need axles; which is $20-$130 depending on who you get them from($130 is for pair at Advance or something with a core).

AHHVTEC · 08-11-2008, 02:12 AM

well i remember myself asking myself lol, why would the weaker motor have larger axles.

AHHVTEC · 08-11-2008, 02:13 AM

but i guess it is possible that the kid that had it before me could have upgraded idk

K2e2vin · 08-11-2008, 02:15 AM

Well even if he did, then the axles would've fit! lol. Maybe you had upgraded knuckles, and the parts dealer sold you Std axles(which I'm sure is very possible, especially at Advance Auto or Auto Zone)?

AHHVTEC · 08-11-2008, 02:18 AM

yea thats what i mean the kid before me could have got the dx hubs and put them on there i guess.

but wait i remember i went to the next part store and they had std axles and it fit fine so were back where we started std= bigger lol

K2e2vin · 08-11-2008, 02:20 AM

That would mean they're bigger than B-series/DA axle ends!

**TravisCadello** · 08-11-2008, 02:20 AM

is this a good page of how to dpfi to mpfi? D2G Automotive Articles 88-91 Civic - DPFI to MPFI Conversion

**TravisCadello** · 08-11-2008, 02:22 AM

and everybody says i need a Si intake manifold?? can i just use the one on my 93 civic motor aren't they the same just about?

and a A6 dizzy? is this a si dizzy or what?

efhondakid · 08-11-2008, 02:30 AM

Yes you will need the Si dizzy and Si IM.

**TravisCadello** · 08-11-2008, 02:39 AM

well, isn't the one of my 93 civic motor the same as a si IM ?

efhondakid · 08-11-2008, 02:57 AM

The 93 intake is OBDI, your car is OBD0, so to keep things simple youll need the 88-91 Si mani.

**TravisCadello** · 08-11-2008, 03:04 AM

and if i wanted to keep the manifold i have now id have to what?

efhondakid · 08-11-2008, 03:07 AM

An OBD conversion.

**TravisCadello** · 08-11-2008, 03:09 AM

This site right here show me how to wire up my stock ecu. and if i wanted to do this I'd have to buy a Si intake and injector resistor box and thats it correct???

For the dpfi to mpfi you will need the following;

OBD0 Si intake manifold.
OBD0 Si dizzy.
PM6 ECU.
Injector resistor box.

Sorry about all the questions bro, But I'm just lost to as why the hell do i need a Si Manfold when mine is the same thing. and also why do i need a PM6 ECU ?

**TravisCadello** · 08-11-2008, 03:22 AM

I dont know maybe I'm just to dam dumb to understand it but to me i dont get why i cant just switch the 2 wires on the ecu for the TPS sensor and move on to adding the 4 extra wires need to run the injectors and run them to the injector resistor box. and fire it up.

I think it says in their you need a Si manifold to do a dpfi to mpfi swap but if i already got a entire motor with a manifold that already has 4 injectors that should be the same thing dont you think?

and the stock dizzy and stock ecu should work by just changing those few wires that this site show you to do D2G Automotive Articles 88-91 Civic - DPFI to MPFI Conversion shouldn't it?

efhondakid · 08-11-2008, 03:24 AM

Like I said you will have to do an OBD conversion to make the 93 intake work. And you need the PM6 because it is the Si computer. Your stock ECU wont work its for the dual point motor. The multi points have two more injectors and a cylinder position sensor in the dizzy, the dual points dont. So to make the conversion work you will need all the stuff the Si has that the DX/STD doesnt. Your making your car into an Si, so you need all the parts that make an Si an Si. Do you understand what Im getting at here?

wait what motor do you have again

K2e2vin · 08-11-2008, 03:28 AM

You can use a 93 intake manifold; you do not need a Si one. Only difference is the MAP mounting. The 93 has it on the throttle body, while the Si is external. Luckily, the plugs are the same so it does not matter. No OBD conversion needed. Only "OBD" conversion part would be is if you used an OBD1 distributor.
