Front Cover Swaps...

vex · 05-22-2013, 08:18 PM

Does a TII front cover directly swap over to an NA keg? My gut tells me yes, but I would like confirmation. Does the OMP stay the same?

I'm planning on ditching my scavenge pump system and go to a simple drain setup (which I've wanted to do now for years). So will it be a straight swap going from a NA front cover to a TII front cover on the S4?

Only difference should be the turbo oil drain return.
If you keep with the same series, it should be fine.
Due to a change in the S5 water pump housing, you cannot run an S5 water pump housing with the S4 front oil cover.
You can go vice versa, cause the S4 water pump housing doesn't have that extra protrusion.

What Ted said. I'm running an S4 TII front cover on my S4 N/A block with no issues.

Saweet. So I take it that the OMP and what not just button right up and go. Cool. I guess I should start sourcing a TII front cover so I can figure out how I'm going to route the drain lines with some -AN fittings...

Yes, OMP flange bolt patterns are the same.
