Hybrid Turbos & "Stages" - 04/04/2011 13:15
Hybrid Turbo Overview
I thought I’d put together a list of the hybrid turbos commonly used on the 20VT. The turbos are listed in a rough order from the standard turbo (least power) to the largest spec (most power) you can fit, and includes commonly referred to names.
Hybrid turbo definition
Hybrid turbos are a standard turbo which has had part of its internals changed from the standard specification and is a direct replacement for the original turbo. A GT series turbo requires a V-band adaptor or a 5 stud downpipe eg GT28RS.
The turbos which have been refurbished should have a 360° thrust bearing & staggered gap seals. These refurbished turbos, hybrid or not, will be able to safely run a decat without the risk of blowing the turbo seals, which is common for the Fiat factory fitted TB28. Each turbo has two sides, a “hot side” the exhaust turbine, and a “cold side” the compressor.
Standard Turbo:
50 trim compressor, 0.6 actuator & 62 trim exhaust turbine.
Hybrid Turbos:
55 trim compressor (Superspool Barbz)
60 trim compressor (CR Turbos Stage 1 & Power Italia Stage 1)
60 trim compressor & 0.8 actuator (GTiR Barbz)
62 trim compressor & 0.8 actuator (GTiRS Barbz)
62 trim compressor, 0.8 actuator & 76 trim high flow exhaust turbine. (CR Turbos Stage 2 & Power Italia Stage 2, FC Performance Stage 3).
Additional Information
Barbz may have supplied his GTiR without the 0.8 actuator which would make it the same as the “Stage 1” turbo from CR Turbos / Power Italia.
Power
Referencing the FC Performance Dyno Thread, the potential for any of the hybrid turbos with supporting mods is between 280bhp (Superspool / Stage 1) up to 350bhp for the Stage 2 / Stage 3 turbo. Flea mapped refurbished standard turbos with or without a decat seem to range from 247bhp - 288bhp (Listed as TB28 in the dyno thread).
"Stage" 1 is a not a standard turbo
The standard refurbished turbos have been quoted as a "stage 1" hybrid numerous times, and stage 1 numbers from the dyno table being linked to the standard turbo (TB28). Flea has confirmed that these refurbished standard turbos are NOT listed a hybrid stage 1, they are listed as a TB28. TimC's car has the highest listed power as a stage 1, with a 60 trim compressor, and so it is NOT a standard turbo.
FC Performance are now offering new listings of hybrid turbos, unfortunately this list does not come with the turbo specs.
