and pretend you have unlimited funds and select all the best of the best products then sit there and wish you could actually "proceed to checkout".
I know I can't be the only one that has done that?¿? lol
ya starting with a "grainger" or boost bleed is where you'd start.
then you Intercool and Up the boost a little more.
then you really start having the fun. bigger turbo, alcohol/methanol injection, extra injectors ect. ect.. ect.. all in the name of more boost

then you blow a piston, have to rebuild and toss in a few performance mods along the way ported head, manifolds, removing balance shafts.
have fun with your New TD, just be carefull and run the good gas. it's more expensive but still cheaper than buying a new set of pistons.
