SwappedTURBOegg

Looking for some in site on smaller bore engines with big turbos.

I have a 81.5mm GSR and i spin it to 9k on allmotor cams.
Now the turbo i plan on running is quite large.

63mm compressor inducer

74mm turbine.

yes i know this is probably "too big" but all that is up to the driver to decide.

as for spool times does 6000 sound realistic?

i have a T3 top mount but im thinking about boring out my t3 housing 19cm to fit this turbo because selling the manifold and buying another is a PITA. is there going to be a downside to running a t3 housingon such a large turbo?


for fun here is the turbine.
