Looking at the on3 76mm that can be had for 350$ with a 1.15 AR or the gt45 that can be had for 260$.

Question is which is capable of more power the on3 is 76mm on the compressor and 66mm on the turbine while the gt45 is 70mm compressor and 77mm turbine.

This will be in a 3400lb g body with a 5.3 and small cam in the 220's

gt45..only because I have been using one for 3 years....
for reference, on only 10 psi Ive ran 10.6 at 128....with a 5.3.

GT45. You will run out of turbine on the on3 before you max out the compressor IMO.

i know VS racing now offers the gt45 with a 76mm compressor. something to look into

CX racing has a 7577 turbo 599 i believe, would be a good option if you have room for it.

gt45 hands down best bang for buck on lsx turbo car, will throw down 600+whp thru an unlocked auto like no ones buisness for like 300-330 shipped with Vband clamp and downpipe starter from VSracing

I thought you bought a 80mm gt45 already?

They ended up being out of stock and tried to sell me the 76mm. This is a differrent build tho. Since then ive built a tc78 5.3 camaro and fixing to get started on two g body malibus with gt45's.

Oh gotchya. Well I would either get the 76mm gt45, or if cost is a big issue get the 70mm gt45 for 260 or so. I had good luck with on3 but my buddy hasn't. Also the tiny turbine will kill you on top end, trust me Ive been there lol
