1. How much would this upgrade cost ( i know the single ballbearing upgrade from turbonetics is in the 500ish 600ish range) and who in our area would be willing to sell/do it.
2. what can my expectations be as far as spool up times
3.longetivity reliability expectations = ?
4. have any of you guys done any of you 2.3T guys done any upgrades like these ? is it very difficult/delicate ?

 

changing center sections isnt that big of a deal

ball bearing really isnt worth it IMO. I had one on my accord (2.2L), and spool time only changes about 400-500rpm. not really worth $600 and something u can not rebuild when it goes bad.

remember this motor revs to 8k though...

with the BB, i made full boost (9psi) around 3000rpm, with a non bb, it would be 3400-3600. t3/t04e 54trim, 63ar. wish i would have stuck with my 57, or even a little smaller with a 50.

 

so that was the single ballbearing upgrade that you got done ? it looks like my 57trim t3/t04e (.63 a/r exhaust and .50 compressor housings) is going to take about 4krpms to get fully spooled using my zetec (2.0L) id like to get full boost around 3500ish rpms , you think if i ran it open downpipe that it would help spool times ? iam looking to atleast make 3-4psi by 3000 - 3400rpms (at the very least)

 

unless ure going to have a built motor, 57 trim is over kill. go with the 50 trim and u should get what your looking for.

open DP will help a little on spool time
