Any ideas if the bypass valve below would be any good? After adding the T3 I think one of these would be a good idea to add.
88 TC 241K:
T3, bored .030 over block and bowl blended, harden seat added, un-cracked head from an 84 TC. Ranger Roller cam, upgraded valve springs, CP forged pistons, self-polished upper and lower intake, mild ported un-cracked E6, cold air intake, bypass valve, looking for 3" exhaust.

I dont see any link?? For boost levels under 18 or so psi, the plastic Bosch valve, which can be found at the JY in VW, Audi, etc seems to work OK. They can be had new for around $30 to $40 or so. I blew the diaphram out of one of those years back at 24 psi, so I got a Forge all metal piston valve that is a direct replacement for the Bosch and am very happy with it. The Forge is rebuildable.

I may push the boost up 20, but I think that would be the most I go.
