are they any good?
also if not i was going to go the factory option is this a mettle layer gasket?

i wouldnt recommend them mate, is your gsr standard??? what engine mods does it have?? get a standard one or a msl

I've got the Jasma headgasket in my car , 1.8mm and it was a f##k around. You have to drill the small lugs that hold the multi layers together cos they foul on the head and block surface, then you have to drill out a hole for the oil to get up to the head cos there isn't one. Other than that I've had mine on for 10k now running at 21psi and there has been no problems.

standard gasket is 1.5mm and i would keep it that thick. I would keep the factory gasket, I doubt you will kill one with factory rods and if you did then it just saved your rods.

just minor mods its tuned to run 98 and yes its pretty much stock internals. but looking to wind boost up to around 15psi once fixed

If it's only 15psi your going to take it up to, I recommend a standard one. I only went the Jasma gasket cos I needed to have the clearance

I agree 15 /16 psi on stock ish motor go standard or felpro you wont have any problems,

just make sure the surfaces are machine properly and the studs are good and it is torqued down correctly

and you will have fun problem free motoring!
providing your tune and everything else is ok

are they strech bolts or can i reuse the old bolts?

 

[Smutt]

Cometic don't do a gasket for the 1.8 "thumbs down"

I wouldn't recommend reusing your head studs being the standard ones

i think the only mls gasket you can get to fit the 1.8's is actualy for the 4g92 mivec. other wise heres a set that has an mls gasket in it

dunno how good it will be though

 

[DOUGMO]

stock bolts are stretch bolts, there is a spec to measure the length to see if they are still ok to use

The 4g92 ones are only .4mm thick. M&H use to make a 1.5mm 4g93t mls about 6 months ago but I think they are hard to get now.

 

[khubner1]

that might be the case how thick is a std one cause from what i've heard is they're the closest to std

order a 4g93p head gasket from proton, or a SOHC head gasket...identical to the 4g93t gasket
as for mls, you can get either .4, .8, or 1.2 all genuine.... the.4 is the common one... the other 2 are a PITA to get off mitsu

The stock gasket is 1.5mm. I have no experience using sohc gasket but was told some coolant holes need modifying when going on a dohc, someone may know something about that. I would not want to go any thinner on std comp engine.
