spacer for exaust manifold?

[smbgsx]

I just ordered a FP cast-iron exhaust manifold and have a few questions...

1) My current SBR mani has some type of spacer between the flange and the cylinder head. is this typical and do you think I will need this for my new FP mani? I'm using an FP30 turbochager.

2) the new header is ceramic coated but I want to reduce underhood temps as much as I can. Do you think wrapping this header will shorten its lifespan significantly? its not driven everyday and never in the winter.

3) I have an EGT probe in my current header that I want to move to the new one. does the probe need to be on the top side of the runner to function properly or could it be mounted on the side or bottom of the runner? this would be just to make the install look cleaner.

Thanks for any help

1) Most people have not had to use any type of spacer with an fp manifold.

2) Heat wrap will reduce the life of the mani and cause cracking. Most users use what is called a manifold blanket.

3) Best to run the EGT sensor from the top as running it bottom side up will cause premature failure. Your manifold blanket will cover it

on point thank you. ill probably run the a blanket with the FP heat shield covering all of it then

from what I have seen most people need the spacer to push the turbo out away from the bottom motor mount and the block. You can trim that mount if it hits.

Thanks for the help but this manifold has been long installed.
