That 60 works ok, the 6152 is a big shot in the arm compared to the 32 you have now. The 60 turbo will have to work harder to make the same amount of power.
Ive had a 60 on my car, it was slower to spool than a te44, and the 6152 makes more power than both. Minimum of a 6152 honestly....
Since you have ported heads, that turbo you have now is doing you no good.
If it were me, 60s te45a(66mm) , 3400 non lockup, fmic, and a alky kit.
Combo for my blue limited is, ported heads, 60's, te45a with .85 housing, pte fmic, 3400 or higher vigilante single disc lockup, 70mm upper and lower, je .020, built transmission. Dual nozzle Julio kit.
I tell you what, its a nice street combo, spools up lightning fast, and plenty of power on tap.
There is nothing wrong buying a used turbo if you can find a good one
I think there is a 6776 journal bearing in the for sale section for 700.00
I was thinking of it for my daily driver....
