S13 is getting twincharged, thats been the plan for ages, just never did it till now where i got a big turbo and top mount manifold for clearance.
will need an elecy PAS pump too, but aside from that the main hard stuff is getting someone to make the mounts, but should go where the aircon goes if you have it, and i have a spare block they can use to mock it up on.
want to on the 360 too, but want to test it on the SX first
