blacktops are better for NA, better headdesign. you dont want to add FI to either one til u build the bottom ends, in which u still want a blacktop bc the head design is still better.

i can get both swaps, blacktops arent that much more and can be ran open.

my 20v swap goes in 1.5 weeks over at XAT and will be running on megasquirt and a ford DIS setup. 1st known blacktop in tampa.

as long as u run a oil cooler and dont run the piss out of it, ull be ok. im going to get a cheap oil filter relocation kit and run the stock oil cooler upfront.
