ok so i have finally gotten some time to get this swap started... i apologize for some of the pictures being blurry, not sure if i had my wife's dslr on the wrong setting or what, i need a point a shoot camera lol.
list of parts needed:
kpro
hybrid racing speed converter or you have to take the trans apart and drill holes and crap
throttle body adapter, i used obx, but i will have to tap the threads...
some way to use reverse lockout if you would like, i have my own ideas, we will see if it works
oil, coolant, tranny fluid... i personally use amsoil stuff.
patience
power tools help alot
a tap and die set

first of all...disconnect battery, drain coolant, tranny fluid, and oil if you want, i did not drain oil.

i also went ahead and disconnected the charge harness from the fuse box.

after removing stock airbox you are able to see alot more of what needs to be removed.

at this point i jacked the car up so i could remove the bumper, this may or may not be necessary but i found it much easier to do so. I also removed the radiator support that has the hood release mechanism on it, you have to twist it but the cable can be detached.

at this point i removed the radiator. be careful! there are several wires and plugs that are attached to the radiator fans that will not let you pull it out so dont force it!

ok from here i disconnected shift linkage. i also removed axles, i justed poped them out of transmission and halfshaft and pushed them out of the way, so i could roll the car in and out easily. also dont forget about the exhaust, i just removed the two bolts going from the manifold to the downpipe. from there just make sure you unplug everything that will keep the engine from coming out, or at this point you can disconnect the two plugs on ecu and one right next to it that are the engine harness and pull them gently through the firewall. i did this because i like to run the harness on the engine out of the car to make it look nice and neat. this isnt necessary but some of the plugs will be hard to get to with the engine in the bay. disconnect all hoses that prevent removal. this part is pretty straight forward... i hooked up the hoist and put a little bit of tension on the engine, then removed all engine mounts... total of 4 of them, front, back, left, right obviously.

ok at this point i am going to try and point out the immediate differences. pretty much everything on the k20z3 needs removed, and your a3 stuff be put on. if i wasnt sure... i put the a3 stuff on. i dont want to have to hack anything so thats what i did. the front mount is the only mount that is ok i believe. the tranny, timing side engine mount, and rear mount all need swapped over. my swap did not come with accessories, so i just put my a3 ones on with no issues. i cannot say if the z3 parts will work as i didnt have them.

notice the difference in the thermostat housing. i have not quite figured this one out, they are practically identical and should swap out but for some reason i am having a hard time putting the a3 housing on the z3, i will post definitive information as soon as i figure it out.

as we all already know, the shifter mechanism is backwards on the z3 and you need to swap over the ep3 mechanism. although if you would like to retain reverse lockout, you will need to use a rsx type s unit. although i have an idea i am going to try out, i will post up if i can get it to work. the housing that the reverse lockout solenoid bolts to is identical on the a3 and z3, the a3 not having it the holes are not tapped, and removal of the z3 solenoid will have to be done to see if and what metal needs removed etc... other than that the obvious mount difference. i also switched the slave cylinder from the a3 because of the clutch line, it is much different and i didnt feel comfortable bending them too much. the reason is the hydraulic line on the slave cylinder is on opposite sides. just to keep it neat i used a3. i also swapped the metal sticking up, i believe this is for the airbox as i intend to still use the factory airbox.
some coolant line differences on the head, these are for the heater core so just use them accordingly when reinstalling.

z3
http://i915.photobucket.com/albums/ac353/michaelmckinley0324/ep3%20swap/IMG_1948.jpg
basically make the z3 look like the a3, pictures def help with this. the crank pully looks a little smaller on the z3, but i still used the a3 belt and it seems to work fine, it is not too lose or anything.
ok so thats all for today. i started work around 12 in the afternoon, and finished at 7. with lots of beer and dip breaks, so this could easily be done much faster, but i like to take my time. having the right tools and power/air tools helps alot too.
anybody has any questions or anything feel free to pm me! will help as much as possible
will update as soon as i get some more time in the garage..
