i have been running 300whp on mine at 1.8 bar. dont see why a td04 will do you any damage to it

His cr ratio & piston type would have to be taken into consideration though mate.. alot of members run flat top pistons, which could cause more stress on the hg.. but i do agree with u i ran 1.5~1.7bar on a td05 for a long time with the oem hg.. only thing is i was running dished pistons.. but otherwise if tuned well it can take a good beating :)

Or are toyota ones better??

std headgasket will not take detonation well, everyone makes wee mistakes when setting up so for piece of mind i would get a better one.

BGA are good, but oem toyota seem to hold much better mate :)

std one will be fine IF youre tune is always good with no little incidents (overboosting, running lean) . my trd one has been good with lots of abuse and the odd turning the boost up too far by accident.

hmm ok, should i go down the Athena head gasket route or will a standard OEM one be fine?? want to run 1.4bar on a TD04.

sorry, but do the Athena headgaskets have to be on freshly skimmed head and block? and are they a perfect seal?

cheers

he said he was running low comp..so i assumed he was using dished pistons.

i am aslo using dished pistons. but even then i dont see how a td04 will fail a oem headgasket even with flat top. pistons.

i made 300 with shaved 5e pistons and still had no problems but then again i am crazy. :haha:

i know a project which ran approximately 2.0bar and 300whp on the stock headgasket----in fact the complete head assembly was stock

bwoy i dont really see whats so spectacular about the tuning we do down here. most of what we tune is just fuel maps. we like to keep them in the low 11's.

probably the problem lies in the engine builder and not the tuner..........

probably its best i not tell you guys what is being down with stock parts as you all might blow the engine to bits. my engine builder has his own specs when it comes to building his engine and his costomers engines. and he doesnt give up that information so as to preserve his edge over competitors.

best you guys just buy the fancy aftermarket stuff. even i am sometimes shocked with the shit we get away with down here. lol. these parts were meant for 100 hp to the wheels and here we are making three times that amount and still havent changed them. toyota is king :rockon:
