The head flange started out as 1/4" and due to some warpage during welding I surface ground it completely flat. on one end it is only 1/8"!Originally Posted by Juggy
whats the flange thickness at the head???? looks to be 5/16 or 3/8 at most
I see the flange has not been seperated between the ports?? is this thing going to bend n flex? warping the initial surface???
BTW looks great!! if i have/had money id be all over it....and yes aaron is right about the group buy section, it doesnt get the exposure it should!
edit: how much space was between the L body firewall and t4 comp housing???? think a GT30R could fit back there with this?but amazingly enough it worked fine and never really warped enough that it could not be bolted flat. Eventually after many 30psi (intake so what 60 in the header?) runs it did start leaking a little on the ends but nothing you could hear. As stated the copies will be 1/2" flanges.
Very close to the firewall with the E cover, Thermotec on the firewall recomended.
