Head Gasket

what up fellas. I am getting ready to start my build up on my Gen2 3SGTE, i am going to start off with the basics and was wanting some feed back on any Head Gasket any of you guy may have put on your engines. What millimeter thickness should i use, should i go with HKS or GReddy?; keep in mind that i wont have to stock turbo for long.
Thanks guys/women

Thicker gasket will lower compression. and I think thats probably what you want if you are planning on going with a bigger turbo. the material it's made of would be the next issue. there's a few other guys on this forum that can answer that better than I. I still haven't decided which type to use when I take my head in. i hope this thread will start some usefull thoughts from the others...

I've got a .05 or .50 ... can't actually remember right now, but it's thick as could be, and is a tripple layer steel gaqsket. I purchased it for my upcoming 5sfte build.

Unless you are going for crazy hp numbers, the stock one should be fine.

Most of the tech's I know say the same thing. the stock toyota head gasket is fine unless you are going for gargantuan HP. Dr. J&H has never opened up his engine and is running 22psi boost and 351 rwhp. on stock gasket... that says alot

but dr. J&H has a 3sgte engine correct? I'm assuming that the 5sfe has a weaker head gasket, and that's the reason I've purchased the .50 tripple layer steel gasket.

I appreciate that correction on the half inch head gasket ... I hate decimal points! but I needed a new gasket for the build anyway... so I figured why not. the internals I've got are as good as they come for this engine, and I really don't want the weak link to be a stock gasket.... and have to tear it open again. but I seem to have a small problem.... more of a question- I purchased ARP studs sold for a 3sgte simply because the sales "person" (couldn't tell if it was a guy or girl... ~~shiver~~ ) told me they could be used on my 5sfe engine... and I trust TN's replies more than some "persons" sales pitch... so any help or info on the similarities of the two head's bold patterns would be appreciated.

I agree, after all the mods to internals you wouldn't want the gasket to be THE weak point.
I don't know if they take the same bolts.Email Dr. J or MRQTurbo. if anybody knows on this forum, it would be them.I know the parts guys at the Toyota dealer here. They will look for me in the computer & see if same size bolts. I'll get back to you tomorrow. I have to pick up my turbo gasket kit that came in anyway..

thanks for the solid info.... I think it's time for me to get a refund. that really blows. so it looks like I'm stuck with using new stock head bolts.....lower boost....and ultimately, a pansy mobile . but hey.... gotta deal with it....adapt to the situation.. less boost and stress should equal a longer life span. I hope.

Do you not think the stock bolts would hold up? What kinda HP numbers are you goin' for?I would think that if you're keeping it under 400Hp you'd be OK as long as detonation is kept in check...what do the other guys on the forum think?

Early gen 5S-FE block will take later gen 3S-GE/GTE head. It a bolt on. On other gen the different is oil and coolant passage. So bolt pattern is the same, bolt length is another question. Find a 5S-FE head bolt to compare before you get a refund.
Someone check the bore on 3S-GE HG. If its bigger then the cylinder bore, it could be use in 5S-FE. 5S have larger bore then 3S. 5S piston raise pass the block and into the gasket. So if 3S-GE HG bore is too small, the 5S piston will hit it.
Wraith in Camry forum is a good source for 5S-FTE/GTE info. He got a post detailed parts he used.
