Here's what I'm looking at for my 93 1.6 and I don't know what thread size to get.

Here's another question. I have been reading that the 1.6 plate should be moved out farther to clear the manifold brace AND the block. I bought the car without the brace, but I'm trying to think what would be the problem with clearing the block? Is it a hose issue where the fittings won't clear?

Would I be better getting the FM plate?

Thanks for the help!

 

If I'm not mistaken, that's exactly what FM sells.

 

Yup. The FM piece is that same Mocal part, however for the 1.6s FM includes a very nicely machined spacer to move the plate away from the block, along with a longer threaded pipe to accommodate for the spacers length.

Incidentally, RPW has the description wrong. Those ports are not 1/2 NPT, they are 1/2 BSP. Very close, but not the same. You can purchase BSP fittings from Pegasus. I replaced the -8AN ones that FM supplied with -10AN.
