What do you Think ?

Checking compressor maps[majestic] the to4e-57 and to4b 60-1 both seem to be in the 70 + eff. for my 3.4 [14.7 / 6000 rpm] .What are the pros/cons for one or the other ?

The 60-1 is capable of supporting more power and has a larger inducer on the compressor (both use the same exducer diameter). Spool should be virtually identical. No good reason not to get the 60-1 if those are your two choices.

Yes I agree. I was searching for some prices after I made the post and ran across this at Turbo Elements : T04B 60-1 comp. 60 trim .70 ar Turbine. p trim 58-96 ar and T3 / 60-1 comp 60 trim .70ar Turbine stage 3 wheel .63ar both deliver 61 lbs/min Does the first one have a bigger turbine ?

cheaper then a ball bearing and much better then a 60-1 wheel

Of the two you posted, the first one does have a larger turbine wheel. Turbo Elements runs specials on Honda-Tech that beat the prices on their website.

The SC61/PT61/T61 turbos that use the compressor from the GT35R are great turbos and can sometimes be found for under $650 during sales.
