hey fellas, just had a read thru. thought id chip in.
ive been running the .92 g25-660 for about a year now. semi closed forged ej25. amazing turbo, spool, mid range everything. almost as responsive as the tiny factory td04.
in my humble opinion, this is too small for an rb. you'll get mad response, but no top end.
runs about 340awkw at 26 psi. under very strict controls, pulled timing, torque limit etc.
clutch and semi closed engine holding us back. still makes 100kw at 95kph, and 200 kw at 110kph.
have since exploded that clutch, now have a new twin plate on there and a more efficient cooler. if i get it back on the dyno any time soon, ill drop back round to post the sheet.
we also, have a sleeved ej28 stroker in the build hopefully to have a g30-770 or g30-900 attached to it. with the current wait times, and gcg having the monopoly (and also charging full price upfront to non traders) it could be a while. once MTQ has stock, we will be all over it.
