Question For Rb25 6boost Users

[rinmak]

Hey guys,

Did you use the fat washers when installing your 6 boost mani? I cant see any possible way I can get the fat washer, the thin washer and then the nut on any of the bottom studs as the runner gets in the way. I can get just the thin washer in there so will this be ok?

Quick replies would be loved as im doing this right now

Thx

Ryan

pressumably so long as the nut tightens down and there is no play between maifold and block, should be no issue. use a feeler gauge to check this adequatly, but yeh 2 washers seems a bit of over kill

[rinmak]

Oh well ive installed it with just the thin washers on the bottom row of studs....seems ok to me.

If any other RB/6boost users have a comment then please post it up

that's a f**king lot of heat wrap there......

just ceramic coat the bartard, does a better job and looks HEAPS better

[rinmak]

Il try the heat wrap for now.

If it starts to come off then il just rip it all off and run it bare. I think 6boosts have some kind of coating on them anyway?

how the hell do you ceramic coat the manifold?? is it same sort of theory as sand blasting? but with sticky ceramic?

*hopes this isnt a n00b question*

ceramic is a liquid coating that is applied to the manifold after either acid or blast etching - its then cured in a oven at very high temeratures. Often refered to as HPC coating as that was the main providers of the process.

as for the original question, i think you'll find the stud holes in the manifold are round on the 6 boost manifold - have a look at the std one and you'll see they are elongated which is the reson for the large washers. the material thickness of the 6 boost's steam pipe will not allow the room required for the large washers.
