AdamB Posted August 6, 2015 Share Posted August 6, 2015 Lads who make the 0.6 ones in America are goodCan't mind the brandPhilCometic? Why are you after a 2mm gasket may I ask? Athena do 1.9mm I believe. Quote Link to post Share on other sites

turbominicooper Posted August 7, 2015 Author Share Posted August 7, 2015 hes turboing an na adam would the 1.9mm AdamB mentioned do, slight raise on compression? Quote Link to post Share on other sites
AdamB Posted August 7, 2015 Share Posted August 7, 2015 (edited) You'd be lowering the compression mate.Thinner gasket = higher compressionThicker = lower compression Edited August 7, 2015 by AdamB Quote Link to post Share on other sites

Idrees Posted August 7, 2015 Share Posted August 7, 2015 We have Athena 1.9mm gaskets available Quote Link to post Share on other sites
turbominicooper Posted August 7, 2015 Author Share Posted August 7, 2015 You'd be lowering the compression mate. Thinner gasket = higher compression Thicker = lower compression yuh but the NA pistons have an extra 2mm on them hence the 2mm HG so with a 1.9mm it would be raising the compression as its thinner then required??

But to get the C/R exactly the same you'd need a gasket that was as thick as a standard FTE gasket +2mm extra? Not sure how thick the standard FTE gasket is, but for arguments sake say 1mm. Therefore you'd need a 3mm gasket to keep the C/R exactly the same as the FTE. Surely the 2mm won't make a world of difference anyway, a small increase in C/R may be slightly beneficial in the scheme of things?

AdamB Posted August 7, 2015 Share Posted August 7, 2015 (edited) Don't worry too much about getting the CR the same, if that was the case you'd be more inclined to change the pistons, as changing the headgasket is a crude way of altering the CR. Like Phil has just mentioned, the increase in CR is beneficial anyway, otherwise may as well just run an FTE (in my eyes). Don't go too thick on the gasket as it increases it's chances of blowing. Like I said it's a crude method. Edited August 7, 2015 by AdamB Quote Link to post Share on other sites
5e colin Posted August 7, 2015 Share Posted August 7, 2015 1.9/2mm gasket works fine on oem 5efhe bottom end Quote Link to post Share on other sites
Mickey The Fish Posted August 8, 2015 Share Posted August 8, 2015 I ran the TRD 0.6mm on my N/A conversion and even though I'm currently converting to a forged bottom end I shall be using another TRD 0.6mm head gasket. The fun of turboing an N/A is the higher compression and faster spool up. So unless your going big turbo and big power you don't need the thicker head gasket. Rob H runs the TRD Head gaskets on a forged 4efe and I know his motor makes serious power. Quote Link to post Share on other sites

5e colin Posted August 8, 2015 Share Posted August 8, 2015 (edited) amigo for your setup do use the bigger gasket makes life easier for our little black box :) better safe then sorry on a oem bottom end if u have to take out base timing your loosing bhp so whats the point thats just my 2c Edited August 8, 2015 by 5e colin Quote Link to post Share on other sites
