99 328i into a 98 318ti

[ALPINEMTECH98]

What I need are the swap off the 99 328i into a 98 318ti are:

+harness,
+ECM
+long block (maybe trans, but i heard 318ti can mount in)
+exhaust &
+cluster?

Do i need to get the radiator reservoir/radiator too?

& about the EWS II----

If I can't get the EWS II off the 328i, then I would have to do the bypass with an aftermarket chip from turner motorsports and still use my key with the 328i ecm, right?

But If i can get the EWS II off the 328i, then by connecting the 328i ECM and EWS II module, the 318ti key should be fine?

Just wondering if I need the keys from the 328i, and key cylinder and EWS II module or not.

If there's anything else I'm missing for the swap, let me know.

Please help, thanks guys!
