Stock HG

[Inygknok]

well, im gonna take the head off for a sec during the week or next week, just to clean up a bit. thing is, i was thinking about an MHG, but all the head machining work and such is such a big hassle that im not really in the mood for.

now, ive heard of other members using the stock HG with ARP studs torque'd down pretty tight (90 up) and working just fine. would that be completely fine to hold just around 15psi max (maybe 16) once every 2 months?

From what I have heard the stock HG, mounted with arp's and torqued down right, can hold upto 400-450hp no problem.

ah great! so the rumors may be true after all. im gonna give it a try, just so i can tell everyone i kicked their asses with an almost stock motor aside from studs and a shimmed oil pump.

i run a new stock toyota head gasket and new bolts. i bounce mine off 15 psi sometimes no problems yet....

Mine didn't blow up until 20psi on an upgraded CT. For several months.

Of course, at that point it blew up rather completely. :)

lol, it was time for it to kick the bucket eh? good thing my engine got rebuilt around 2 years ago and only has around...... no more than 30k miles since then. might even be exaggerating with that number.... i should really fix the odometer.

[GrimJack]

Not entirely. My engine was in good shape - I was pushing it beyond what it should be able to take on purpose.

ah, masochist ;)

What all did you kill Dave?

[GrimJack]

Err... #2 ringland, piston surface, rings, stock headgasket, and #5 rod bearing was fried. And a radiator hose, the seals in my water pump, and something else that I can't recall offhand... I don't think the rod bearing was related, it had been like that for a while.
