Hello guys and greetings from Cyprus!!!!!

I am thinking of using a TRD headgasket on my forged 4E vf30 setup due to Cruise hg failure.... I was running a 1.2mm hg and now i am thinking of using a TRD 0.6mm hg...
Any opinions or expiriences about TRD gasket and what is the limitation of boost that can handle from the VF30 setup....
I know that with the thinner hg the c.r. will raise... Is this affects me from running the engine at 1.6- 1.8 bar of boost??? Also is this hg reliable??
Thanks in advance and please let me know quickly because the car is daily driven and must be fixed immidietly!!!! ;)

You will have to adjust your fuel and timing maps to compensate. You will more then likely have to run lower boost pressure with the .06mm headgasket unless you got access to high octane fuel. In my opinion i would go for a thicker headgasket as you will have to resurface the cylinder block and head for the headgasket. I think that is alot of boost pressure for a VF30, but you can peak 1.8 bar then tail it off at high revs so not to overspeed the turbo.

you will give yourself/your tuner a headache with a 0.6hg at 1.8bar of boost.

The TRD headgasket is tried and tested and proven to work, it is a very high quality headgasket used by many members here to great effect. I think for what you are trying to achieve, this combination will increase cylinder pressures sky high and more then likely blow the headgasket which really is not it's fault, unless you go conservative on the tune and boost pressure which it seem's i don't think you want to do :haha:

ive ran 265 hp at 1bar on just a td04 using a trd hg.

it works, but at the boost your talking it imagine that your tuner will have his head cut listening to det and struggling to get any timing into the tune.

Chris/Tim@TB/weejohn/jay/sxturbo could probably share more info but basically by upping your static compression you reduce what you have left to work with when tuning.

on my previous setup i was running a vf24 at 1.5 bar with a ZEP 1.2mm hg and made 289hp atf , 253hp atw.... now with the vf30 turbo, the 0.6mm hg, a 5E intake manifold and a 5EFHE intake cam at what boost probably would make 300+ whp safely???? :-/

My aim now is 290-300 whp... Is this possible with the VF30 and a 1.2mm gasket??? :-/ new mods will be a 5E intake manifold and a 5EFHE intake cam...

Pretty sure Jaycglanza17 is running a TRD headgasket.

He has TD05 at 1.5 - 1.7bar. Mapped on standalone ECU.

I believe he is mate.
You could always double up on the TRD gaskets to make 1.2mm. I've heard they are very good quality and take a lot of detonation before they blow.

Great option this head gasket. Mine took loads of abuse without any Problems. Helps with off boost performance.
