im swapping a z3 into my ep3, will i need anything special for it like fuel lines, clutch lines and all that?

 

I didn't need them, but you do need few other things(you may already know of these):
1. TB adapter between a3/a2... TB and z3 intake manifold
2. Speed converter box (I used Hybrid racing)
3. type-s 6 sp shifting mechanism or some a3 5sp ones come with precut slot already
4. some wirings here and there
5. Reverse lock out switch is optional

I did get other items, but those were just optional/upgrade parts. If you have any question, just pm me. GL!
