Might want to check out http://www.turbobuick.com/forums/ if you haven't been there yet. simple 08-02-2004, 11:14 PM www.gnttype.org is another good website with tech info Timberwolf 08-02-2004, 11:36 PM Just ordered a PT61. Specs are here (http://www.precisionte.com/products/products.php?view=page&qtype=Buick+Performance+3-Bolt&qvendor=Precision&qproduct=PT61&qcategory=Turbochargers) Fast Caddie 08-03-2004, 08:00 AM Had a TA-49 for the last few years but sold it a few months ago. That thing would SCREAM over 20psi and spooled about like the stock turbo. A buddy of mine is running a TA-62 on his 86 and it isn't near as loud... but makes a little more power. Just a little :) (mid 10s) JZ 97 SS 1500 08-03-2004, 10:02 AM I'm running a T70 with a .85 A/R. Works very well... Jose Brcarz28 08-03-2004, 06:19 PM Just ordered a PT61.
