This week i bought a full Gas Research setup. I need to order forged pistons for the new motor im building. Wat compression ratio should i be running? Also is there a difference between an X-1 and B-2 convertor?

You should ask gas research about the convertors, Ive never heard of an x-1. Compression ratio can be the same as standard 7.8:1, basically comp ratio will largely depend on how much boost you see your engine using.

gas likes compression!!! and it also likes vaccum.. i'd just stay at 7.8:1 i went with the GRA setup and mine is 7.8:1 with no problems.. cause when you start boosting you'll need that lower compression to allow things to last longer.

im making **** power due to standard turbo... i'd say 170ish rwkw. ive never had a power run with my setup.. all thats left for me to do is, turbo/Wastegate, and ignition system. and maybe a set of 19's for cosmetics.. wanna hit around the 250rwkw on about 18psi.. thats my aim, if anyone's got a problem or thinks its far fetched, PM me with reason cause i dont like to talk **** i know its very possible.
