Default twins on a 4.8ls

Im building a 4.8ls budget build and have twin ebay gt45 turbos left over from my last build.I was wondering if anyone has tried spooling anything like these on a 4.8ls.I have a stage 2 turbo cam and pack srpings everthing else is stock.Just wondering if you can get any boost on the brake with these turbos on this small of a engine.Would love to hear what people have done and boost and hp numbers.

I've had good luck with more turbo than a pair of GT45s on a 4.8.

Guys spool 94/102's with 6 cylinders, you'll be fine. Better question is if you do get them singing off the line will you be able to hook it?

Tony ran his 351 on a pair of them. Super lazy but made power.... eventually. Little less than the S480 at the same boost number on the same setup. Best I've seen done with them. I think you'd need a 6k converter and an 8k+ redline to make them work well.

2600rpm - 96kpa/0psig
3000rpm - 108kpa/1.74psig
4000rpm - 133kpa/5.37psig
5000rpm - 197kpa/14.65psig
5500rpm - 250kpa/22.34psig
6000rpm - 300kpa/29.59psig

I’d pull that **** off as soon as it cooled down! Maybe wouldn’t even wait until then.
