i have a s4 TII now and thinking bout doing the swap. should iget a jspec RE and drop it in or rebuild my 104k block?
either way ima be running my stock s4 turbo for the time being and maybe a haltech.
so going for 300hp is out of the question right now hehe

 

if 300 is your goal, just build what you've got - maybe get some of the S5 rotors and have your assembly balanced, but you don't need to mess with an RE. you can build and possibly start tuning what you have with the money it would likely cost just to acquire an RE.
