TFS heads 1.6 rr a stock ported intake, SLP runners plenum ported, SLP headers and cat back. I had the SLP stuff on waaay b4 the heads.. Cam came later !
Im not sure what it picked up but it was plenty for the day.
I also put AFRs TFS and several other heads on fox mustangs with well over 100,000 miles on them and run thier nuts off.. Still!!
I even put heads an TTkit on a stock shortblock stang with 150k on the clock! and its still runs low 10s n the 1/4..

Yep that 60mm is definitely on the small side, not to mention a cheap ebay turbo. There are some 60's that will support more power and in my case I'm going to have to stay around 64-68mm because of clearance issues I think. I'm going to borrow my friend's Precision 67mm in a couple of weeks and see how that clears.
i had an old ebay 61mm turbo and i think the housings are very close to the size of the mp t70 if not the same.
the precisions billet stuff is nice a billet 67mm wheel would outflow a standard 70mm anyways
when i built my setup i left enough room to upgrade to 70mm turbos for sure and might even be possible to fit a pair of 76mm's on there though i would need a seriously big ci wise engine to run that high. my 355 would prolly run its best with a pair of 61's/gt35's
if this setup dosent go fast enough for me i see a 434 ci build with a set of afr 227's and twin 70mm's in my future lol
