Which -if any- of these two Garrett BB turbo's would work on a c900 (2,073 cc with 92 mm Cosworth pistons, c.r. ~8.5-9.0:1, projected hp 280-300, daily street/occasional trackday use)?
TB 2808
Turbine A/R Type Exducer Trim w/gate
0,64 53mm T25 42mm 62 yes
Compressor A/R Type Inducer Trim actuator
0,6 60mmT3 46,5mm 60 yes
GT 25 BB
Turbine A/R Type Exducer Trim w/gate
0,64 54mmGT25 47mm 76 yes
Compressor A/R Type Inducer Trim actuator
0,7 76mmTO4S 53mm 48 no
Both are available w/T3 flange, and prices are tempting (only good to 08/31, tho'). Supplier -who just passes on the spacs from Garret - sez TB 2808 is good for 230 hp -which seems very low for a T3/60 compressor- Turnonetics quotes 280 hp for same unit. Quote on GT25BB is 350 HP.
Any insight here?
TIA,
Eric
