Is the to4s a good all around street turbo? Or is it too big? I do mostly street, with some drag, some autocross and a little roadracing.



Running on a stock port s5 13B



Thinking .96 undivided.

Word is its very good for street use. What turbo are you using right now?

find out what rpm that thing will spool at autocross you want a faster spooling turbo...there was a guy here using a to4s in his rx he drove it at an auto cross...it didnt do to well took to long to spool up..but thats just what I saw and he wasn't a good driver so that played into it.

stock s5



anyone know how quick it spools? How much power between 10 and 20psi?

to4s with a .84 p-trim exaust will spool fast and do everything you want.. It'll do better if you throw a nice ex port and decent size side port behind it...

divided or undivided? How much power?

divided low 400's on pump gas with a GOOD size port. <500 on race gas

i woudl look at t04e 60 trim

to4e 60 trim, 60trim being compressor wheel size as in a 60-1 sized compressor wheel?

Nope, the 60 he is talking about is the compressor housing a/r, the wheel is a to4e wheel.. I would recomend the T04s, it's a good all around turbo and if you don't have what you need to make 400 (IE. FUEL) you just don't run that much boost.. It's a good all around turbo that will make good power from .7-1.5 kgcm of boost or 300-500 hp..
