I was on Shearermotorsports website looking at their EVO turbo choices.

I wanted to know which one of these turbos would be best?

taken from their website:

SF-11001 T3 GT35R Turbo Kit (650whp) $3900.00
SF-11002 T3 GT3076R Turbo Kit (500whp) $3800.00
SF-11003 T3 61mm BB Turbo Kit (600whp) $call
SF-11004 T3 60-1 BB Turbo Kit (500whp) $3500.00
SF-11005 T3 50 Trim BB Turbo Kit (430whp) $3500.00


The turbo's in question would be the ones that I bolded out.

What the heck is a T3 60-1?

how do the turbo's in boldprint compare to one another in terms of spool-up and max power potential???

Thanks for reading.

 

T3 60-1 is a T3 hot side mated to the 60-1 compressor typically found on a T4 family turbo, made by Garrett. Fairly common compressor that's used by lots of rotary guys that offers decent top end power and good spool and well liked by true street cars. It's fairly easy to find a compressor map. Maybe at ATP or Turbonetics web site? That's all I know!

 

the 50 trim i s asweet turbo i run that now,
i made 400 whp on pump gas you can get more out of it then 430

 

50trim could refer to more than one wheel, without saying what compressor series it is from that is kind of useless.
You have the T4 50 trim, what shearer is advertising has a BB cartridge. That means it could be a GT series wheel if they have a comp with an inducer and exducer that end up being a 50 trim. It's most likely a T4 50 trim, but I don't know why it would ranked that low for HP.

T4 50 trim and 3076 should be similar on spool, turbine housing, turbine wheel size, and manifold design can make a large change in spool though so don't look at two people with different setups for comparisions.
60-1 will be the laggiest of the three.
