What size HG for a turbo rb25DE

[Iknowthefuture]

I have a de that I am going to throw a turbo on. as of now its on the engine stand waiting on arp head studs. i have the stock replacement de/det HG from the rb25 gasket kit. I found that the DE has 10:1 compression and IIRC the HG is .051 thick and 86mm bore. the rotating assembly is still stock and hasn't been rebuilt with 60,000 miles on the ODO. I just want 300-350 if I can get that now as a DD, until I rebuild the motor.

Which gasket and what thickness should I go with?

9:1 ftw?

Could I reach my goal with the oem HG, copper spray, and 93 oct?

if you have no luck here, try this question in the RB specific forrum...

An oem gasket could handle 350 easily. There are setups with 400+ on oem.

the rb25de has a point higher of compression than the det... i know that the gasket can physically hold it, i'm worried about detonation on pump gas.
