i think all the questions were answered! thanks!
differences from a shelf tti race-water kit:
-intercooler water tank, hoses, fittings, pump from engien bay to behind drivers seat
-i no longer have an intercooler water radiator (it is not my trans cooler!)
-turbo change from original gt80-r to the pt-88 and now this
-re-made merge pipe for larger exhaust housing to clear water pump, change to 3.5" downpipe flange from 3"
-change from 2.5" to 3" and now 3.5" discharge pipe on the turbo end
-wrapped header at alternator as well as the cross-over piping
-now inlet 90* elbow change from 4x4 to 5x4
-changed from short k&n filter to 12" long cone
-some clamps, couplers and junk like that

i didnt get them back with the engine, but I was told that they were in good shape considering the miles and use (abuse). the entire rebuild consisted only of rings rod, and main bearings, so that says something there.
the erl ls2 block has some filler in the bottom of it and billet mains (on my stock crank) w/ standard replacement main studs.. thats it far as i know.

hey i know this is an old thread but how was that 91mm upgrade? did it spool about the same? how much hp did you gain? wasn't the t4 housing chocking the engine up high? what a/r?
i had my pt88 seize up on my new out the box...

spooled faster than the 88, not sure how much gain. the new owner in texas dyno'd 1060 to the tires thru the 4l80 unlocked yank converter /9"
my pt88 as well as this 91 was no issue from either, sorry to hear it.
here were my last passes prior to selling
