So it's time for a new turbo and looking to replace my old T25 from an S14 with a GT2860. Anybody have any thoughts or experience? My initial impression is that this may be too big as I'd prefer quicker spool over top end, but I'm open to suggestions and comments. Would like to keep with my current T25 manifold/ 5 bolt flange downpipe setup. 200-220hp is perfectCompressor Size:

* Outlet: 2"(51.2mm)

* Trim: 48

* Inducer Diameter: 49.20mm

* Exducer Diameter: 71mm,

* A/R: 0.6

Turbine Size:

* Trim: 76

* Inducer Diameter: 53.8mm

* Exducer Diameter: 47 mm

* A/R: 0.64

 

I use a gt2871r and it spools pretty quick for me.

 

Thanks Pepe. Has me curious, what engine/boost are you running and what RPM do you hit max boost at? Any idea what your A/R is?

 

Check the random chat thread i just posted some logs

 

Might not be a good comparison since i have the internal gate welded shut and control boost with a tial 38mm and aem v2

the stock gates start to crack open and bleed off exhaust sooner
