A testpipe made a night and day difference for me. Running a tad cooler EGT's, faster spool up, and just more power overall. The bad things is that it stinks, but who cares!!

^^^hell yeah, i don't have a 60mm, but when i did the 57mm bore on my stock, it made a hell of a differnce. you intake more air through your intake manifold and more air gets to the combustion chamber quicker. also thottle response is way better.i would say do that as your next mod or port and polish your intake manifold. you'll notice a difference in power. i can't wait till they make the new intake manifold for us, especially when we can use the mustang TB's. i want to see how our cars respond to 70mm TB's.
when ur turbo the biggest things u can do that will make a diff have to do with intake and exhaust. besides...a turbos two factors are exhaust flow to make intake. bigger intercooler pipes, colder air, bigger tb, p&p manifold, fuel coolers, 3 inch dp and test pipe with 3 inch catback, etc... milk that turbo for all its worth! hah _________ 96 talon esi-t san clemente, ca
if you get a 55 or 60 tb you must port the intake manifold dude to get the most power for the buck. the udp is not what everyone thinks. i could not stand 5psi it was too slow when i first got my turbo install done. had it for 5psi for about hmmm 1 day then i went to 9psi.. lasted about 2 years on 'my' motor about 18,000miles about.
