Sorry for taking long to replay my internet was off.
People here use the w58 boks to drag with because the v160 is so scares and expensive. It will handle the 500hp but it depends on your driving if you drive hard it, won't last long.

If you can use the oem ecu its much better then an aftermarket one.
Aftermarket ecu take a lot of tuning to get perfect.
On the exhaust side you don't have a choice so you're doing an engine swap into another car so you need to get an exhaust made up for you wile you busy do it from the downpipe.
