Just purchased 91 CRX DX need some advice!!

[mwile2k5]

Would this be a start of what I need for the MPFI swap?

[thefooshmeister]

you could start with that..or look for a d16a6 (si) intake mani cuz itll get better flow.. i think pbrizzle or someone had a whole mpfi kit for sale on here..lemme look around..

Cool thanks, man. I just picked up 2 complete 90 CRX doors, for $50 total, little rusty but are in better condition then what I have. If you want the driver glass out one of the ones Im not using we can work something out.

[thefooshmeister]

does it have the belts in the door??? that be amazing!! yeah ive got some parts lyin around that youd need for mpfi idk what all you want for your crx. lemme kno asap about that glass

The intake you have pictured is a HF CRX intake.. it will work, but not well.. you should get the dizzy off that car tho, you'll need it for the swap. (You could use an Si dizz, but you'll pry get charged out the ass for it, and they're the same thing.)

[mythbusting] the Si has more powerful spark than the HF. MYTH
The HF and Si use exactly the same parts, including the ignitor, and the spark is identical in either application. [/mythbusting]

i think i might have an Si dizzy but ill have to check when i go home next..got a busy week ahead..blehh..

List of MPFI parts:

Random wires (preferably the correct colors.)
HF or Si dizzy
Si or random D-series (Not HF) Intake. (Y8 if you can find it.)
Si or almost any other Honda TB (MPFI, obviously not HF)
Injectors (Any honda, make sure you get the wires, and the resistor box if the car you got them from requires it.)
Fuel rail (again, make sure it's from teh same car as the intake)
Intake gasket
TB gasket (not really necessary, I replace them anyway)
Si ECU (Not HF.. it will run, but you'll blow the engine in a week.)
Tune-up kit.
a few random plugs from under the hood (see depinning wires)
A small needle to depin wires
a few other random parts, that you'll probably break/found broken as you're working.
The Intake bracket that bolts to the block, if you care about it (I don't.)

Hey guys picked up the following parts for my MPFI swap today I know I need a few more things. I drove about 50 mi. for these: for only $45. Not a bad deal.







So what else should I look into getting? I heard if I decide to do this I should also look into doing the water pump, timing belt, and si cams in soon also? Should I look into doing this? Ive seen these timing belt water pump seal kits go anywhere from 50-100 bucks on ebay. Are they decent? I know I should get the SI one no matter what though right? Here is one I was considering:

get them from teh parts store...

The list is up a few parts.

Don't use the Si cam, you won't be able to time it correctly w/o a adjustable cam gear, use a B2 cam if you want the upgrade, but I'm pretty sure your car is already a B2.

Looks like you're missing an injector there, you'll want another one of those... You'll still need a resistor box unless you get another injector from a 92-95.. DON'T get anything else unless you get all four... the intake you have is from a 92-95, so unless you get 4 new injectors, you need 92-95 injectors.

[FrodoGT]

You will also need the ecu from the car to match the intake manifold..if you want to stay obd-0 then you will need the resistor box and the injectors from an si.

[Christ]

not true.

The ECU doesn't really care what injectors it's playing with.. both send the same signal the resistor box is just there to make sure that you don't overpower the injectors.. (peak/hold vs. saturated), so you can use the PM6 for the swap regardless... (learned this after swapping DSM injectors to a 91 Si) You can actually run the resistor box still even w/ the 92-95 injectors, itwon't hurt them, but they'll never peak.

[FrodoGT]

It does however care what size the injectors are..

*edit* After a little looking, im pretty sure they are all 240cc..so go hog wild.

[thefooshmeister]

we're gonna hit up the junkyards around us this weekend probly and im gonna show him what all he can nab parts from..gonna try to find him a decent y8 but mostly just focus on this mpfi swap. i forget what all wires he needs to run..is it just the injectors and the resistor box? or the dizzy too?

[Christ]

dizzy for the CPS, injectors, resistor (if applicable), pretty sure that's it, have to swap the two outer wires on the TPS tho.

And yes, they're all 240cc.

Except DSM blacktop (?) they're 450.

I use the DSM orange/pink top 240-260's b/c they're dual spray, and the fuel hits the valve caps rather than being sprayed into the intake stream.
