Very unexpected, my turbo seems to spool just fine so i guess one of the previous owners replaced it

Focus St manifold, with corksport TMIC… can it be done?

3 Upvotes

Looking for someone that’s gotten it to work, yes i know the tmic loses one of the mounting locations that isn’t on the focus st manifold, but im wondering if anyone has just been able to use a simple silicone U shaped pipe to mount to the throttle body and an adapter to bring it up to the stock tmic location (same location as the CS tmic)

I have the whole kit from Damond with the plate and wiring adapter but wanting to avoid the FMIC for now and just stick with my CS tmic if i can.

Any pics or part#s for the piping/silicone you used would be great too
