actually they are not. the difference is in many areas. from flow to vtec cam lobes to which distributer it can/should take to the cc's of the combustion chamber.

i went from an 91 dx dual point motor to an 89 rebuilt mini me si high compression motor. i needed wiring, a msd switch for the vtec, and i am running obdo. and trust me, i need engine management badly at certain points in my power band.

i used a d16a6 block, y8 head with y8 intake. the y8 intake and throttle body was from an automatic, so we had to modify it for for a few things.

there are diff's in everything. if you want your engine to run correctly, get it off the dual point and get it on multipoint. you'll need to wire in the two injectors and extend the other two. plus what i have mentioned before.

"Also, If you hold it at around 1.5k rpms and try to drop it in gear it just instantly bogs down to 500 rpms, and doesn't do anything even if you hold the accelerator to the floor."

the reason your car bogs down is because you don't have enough air or fuel to make anything go. check your spark plugs, my bet is that they are white with hardly any burn on them at all. meaning you are running really lean.

you are using an ecu that is telling two non-existant injectors what to do for a head that was built for 4 injectors and running on a dual point. it also has air maps for way more air intake than what the dx provided.

goodluck.
