R34 GTT boost levels

[kngp2104]

Ok, there seems to be lots of confusing information out there about the GTT. I would like to know if anyone has some first hand experiance of what sort of boost levels can be run on the std head gasket on the ER34 GTT??

I will obviously be upgrading my Tubby, Injectors, fuel pump etc.

Thanks

1 bar i think with FMIC, recommmended 0.9 bar

Yeh. 1 bar with FMIC maybe a bit more if car is not for track use. ie fang it once in awhile as a daily driver but thats with the standard turbo. I regards with how much boost the standard head gasket can take, i'm currently running 1.5 bar as a daily driver with no problems yet. This is not reconmended if you are planning to do track work hehehe..

Someone here in the states made 587 RWHP with a standard bottom end, head bolts and headgasket with 1.7 bar.

However he did mention the HG started to go. I sure the safe limit is far below that

I have a FMIC, GT2835, fuelling, power FC etc, but there is very little info ocer here about tuning the GTT. plenty about the R33 though.

So I guess the GTT has a stronger head gasket than the 33 :wassup:

Thanks Guys
