you sir are a tool. what does 1.7 rockers have to do with anything that has boost. i think you should look more into buying a B16A SWAP FOR YOUR SLOW MUSTANG that will only put out 350HP with 2...count them, t w o turbos. please, my lawnmower from ace hardware would outrun your slow, crappy, crappy, crappy, crappy setup just because you're slow and will always be slow and you are the slowest of all slow mustangs because you want TWIN, TWO, DUCE, DOS, A COUPLE of turbos but only want 350HP. You win for worst post on the internet. Here's an idea, put your stang up for sale on craigslist and then hit the unregister button on this forum and go buy a slow honda. its time to jam, eurotek sound, eurotek sound.
EDIT
To answer your answer I think we will find that you are helping someone that is a lost cause. the gentleman wants to run TWIN TURBOS and only make 350HP. Seriously, think about it...take a step back, ponder about life's mysteries and take in the horrible truth that this entire thread is going to be FAIL. The earth is flat and jimmy just sucked the turtles left front index toe nail with green scaly toenail stuff on his foot that is attached to his shell which makes up overall mass of his tiny turtle body.
