First street pass in my ls1 billet VS 78/75 Made my first hit tonight, need to do a lot of suspension tuning it appears. But, for 8# and 15* she rolls out pretty good. i can't hold the car to do a decent burnout. H/c ls1, ptc converter, th400. Left off the brake on 3#

I’d be looking at that tune real close. If you damaged it at those power/boost levels. Forged pistons aren’t going to solve the issue.
99% of the time don’t want a restrictor on a journal type bearing turbo… Why would this turbo “not require much oil” ? What are you basing this information off of?
Because someone used a restrictor and his turbo lived, that doesn’t make it the correct practice. Use the Garrett journal turbo oil supply and drain specifications for the china stuff and it’s never let me down. If the turbo smokes etc.. you don’t need a restrictor, you need a bigger drain. To my knowledge unless you are running oddly high oil pressure or run a ball bearing turbo… you don’t need/want a restrictor.
There is X amount pressure and flow that should be supplied to a turbo, if you want to be really **** about it, monitor the flow from the drain for 1 minute and the pressure supply pre turbo. If you aren’t doing this and are just guessing you need a restrictor because “the internet said so” , don’t be surprised when the turbo craps out.

Factory ring gaps, when I built the engine I wasn't planning on running boost. It was on low boost yes, but I am roughly 11:1 compression. This shortb block has had a rough life, im not surprised it happened.
5# and 13*, 186* iat max, roughly 85* Sunday. New engine rings will be gapped accordingly. Now I can build my 347 lol
