Two questions:

1. Do you think a 2GR-FE head gasket will fit the 2GR-FSE? I think it will, but would like to hear some more opinions.

2. What is the stock 2GR-FSE head gasket thickness?


I am trying to add just a small amount of margin of safety for the turbo build I am working on. I dont plan on going to a crazy boost amount. Probably only 7-8psi, but would enjoy this extra bit of safety.

Opinions welcome.

 

meh......Im almost certain it isnt worth all the trouble. switching from a .027 compressed gasket to even a .051 only reduces compression by .03


Doesnt even seem worth all the effort.

 

Cant help on the head gasket comparison, but if the only benefit is the very minimal compression reduction I'd skip it. I'm at ~10,000 miles on 7psi without any issues (12:1 compression on my 250 too, versus the 11.8:1 i believe the 350 has), AND youll be using your mapecu, so youre good

Good luck on the build.

 

you're right. THanks

 

I would have to agree, unless our HGs come in a multi-layer metal arrangement. Then, if you wanted, you could purchase multiple HGs and stack the center layer. BUT, for the added cost and the possible complications, I'd most certainly stick with a single OEM HG.

Do you purchase new head bolts when installing a new HG? Are the OEM bolts torque-to-yield?

 

Good idea to stick with the OEM gaskets. Yes, the bolts are torque to yield. 27ftlbs+90 degrees+90 degrees.
