metal head gasket experts inside

[two40splease]

I just can't decide on what thickness I need. I'm either going to buy a cosworth or apexi. I may push up to 25 #'s one day and the turbo I will most likely will be going with is the gt2871r this summer. I currently run up to 18#'s on a t28 and i know its time to swap while my luck is holding out. What do you guys think for size 1.2 ? 1.5?

i wanted to keep the stock thickness for mine but they were out so i went witha 1.1 mm no the thing is it will lower the compression ratio a little. so you stick with thinner one and you will theoretically get more power. cause forcing more air in a smaller area.

so i say stay stock or only go one size up.

Either or will work perfect for you.

Either or will work perfect for you.

hoped you would resond Ive been one of the many reading your 400hp thread for the gt2871r.

Which head gasket would you go with if it was your car.

Either HG will hold 25+ psi (apexi will hold ~45psi according to Mazworx). Cosworth HG is a good one and is much cheaper than the Apexi.

Just a small FYI for you Idaho. 1.1mm is stock thickness. .9mm is for non-turbo SRs

weird. thats not what they told me at phase2 when i placed my order but they could have not understood me.

cause i wanted to get stock thickness and they are like we are outta that thickness so i asked for the next size up.

well i will just take what you say for fact then. i was positive lol.

This is taken from Enthalpy's CR calculator:

NOTE - RWD/FWD SR20DET is 1.1mm thick stock. FWD SR20DE (NA) are 0.9mm

I personally have an ApexI on my car....but it's been on there now for a while...there was no Cosworth option then

If I was redoing it? I'd be running a Cosworth Gasket, simpy due to equal quality and a chaper price. If money was no concern, the ApexI

[DrifterProdigy85]

Apexi hands down.

[driftin_sr20det]

Cosworth, hands Up.... Haha Both are great.

[sk_8ersteve]

I thought that the difference between the apexi and the cosworth is that the apexi HG is reuseable.

Can you safely reuse the cosworth HG's?

I thought you were able to re-use all metal head gaskets. I got the cosworth head gasket and I'm loving it.

[two40splease]

Im buying the cosworth which size are you all using and why

[efrain240sx]

I'm using the 1.1 mm.
