Storage Unit Project: The Menace

I am doing a 08 s4 b7 4.2 v8 Rebuild. I am calling it,
Storage Unit Project: The Menace !! I have little experience of working on cars besides what I learned on an a4 b7 2.0. I found the s4 while searching for parts on the a4 learning how some s4 parts are considered upgrades to the 2.0 A4. I found a total loss s4 with 96k miles on it. Just needed radiator ac condenser and the hole manifold patched or replaced. If anyone has any insights on 4.2 engine rebuilds please pass them my way. I’ve taken information from here about the M90 supercharger and AUDIZINE but feel like alot.of stuff is hiding so that no one can pick up on how to make this rebuild cheaper, the m90 post that I don’t need 13k for this project really was a game changer. I’ll post some pictures of my 2.0 a4 upgrades and the progress of my 4.2 s4. I got the s4 salvage title for $1400. $2800 total with fees and delivery to my front door. I’m now into it for $3300 with the total cost of car. Rad support, air compressor, storage unit rental fees, and the 4125w inverter i bought to supply the power to this rebuild. So for $3300 a shot at the baddest car around my area a legit 1 of 1. I stacked all the remaining chips i had left on black which is like my soul, so far we’ve been hitting big !
