Headgasket Options

[95celgt]

Hey guys, i was wondering if all headgaskets are the same? in bore size i mean, im looking into buying a metal head gasket and want to know if i need to specify that my block is bored 20 over (.020). I think im gonna buy an ACL one (the people that make bearings ;p) so can someone be so kind as to telling me what I have to torque the head bolts to? also should 1mm thick be fine or should i get a thicker one?

HG have a slightly larger bore than the cylinders to allow for overboring.

As for how thick you need, that depends on what C:R you want.
Keep in mind if the head and/or block have been machined this will lower your C:R.

The head bolt torque will also depend on what HG you use and what head bolts you use [might as well get studs if you're tearing into it].

Anyway you can piont me to where I can buy one other than ebay? Thanks:)

most 3S-GTE hae gasket com 88MM that should be good even if you went 60 over the stock bore...

Out of curiousity what are the differences between 5S-FE and 3S-GTE headgaskets. Can they be interchanged (i.e. can you use a 3S-GTE head gasket on a 5S-FE without modification?)?

Anyone have pictures comparing the heads, blocks, gaskets of the two engines?

^ no they are not interchangable.

3sgte = 2.0l
5sfe = 2.2l

cylinder diameter is different, so there for the HG has a different hole diameter.

Well the 3S head can go on the 5S block. The cylinder bore is 86mm (3S-GTE) vs 87.1mm (5S-FE), therefore if the gasket bore is 88mm, I would think it would work on both. Just curious, that is why I would like to see a picture of a 3S head or gasket and a picture of a 5S head or gasket.

I thought machining those two would increase C:R. (that's what you must have meant)

Makes sense for the 3s HG to go on a 5s block.

Pics would be nice, (if only ice with his 5s-gte had some pics of the diff. HG)

Any headgasket that's interchangable for the 7A-FE ?

Or any know who that sells reinforced ones for this engine?

toyota sells a metal headgasket for the 7a.



the 3s and 5s gaskets are not interchangeable because of the water jackets in the gasket dont line up from motor to motor.
