13b-rew crossmember mount cover
Trying to understand which cover to use in order to mount via the crossemember and front cover. I have an Rew and but not sure if the front cover has to be a GSL SE 12A or 13b cover to do this conversion?
Thanks Ryan |
it depends.
the only difference between a GSL-SE front cover and a later (83?-85)12A front cover is the metering pump mounting. the GSL-SE uses the same 4 line mechanical pump that the S4 FC does, and the 12A has a 2 line pump. if you run no metering pump, than any 74-85 front cover works. both the late 12A and GSL-SE front covers have the undrilled casting boss for the turbo drain that was used on the 12A turbo. the early 74-83? 12A covers are the same as the later one, they just don't have the boss for the turbo drain. as an option i have seen an REW front cover with 2 blocks welded to it, so you can keep the FD cas, and front mount the engine. |

I won't be running an OMP. Plan on running a single hall on an elite with this setup as well. So adding a bung to the cover is not an issue. Not a fan of the CAS and its slop anyway.

oh then any 74-85 front cover works.
