Head Gaskets 7 mge
 
Hello.
Tell me please what should be thicker gasket for the engine to reduce 7mge compression 8,4,1

I don't know if u can lower it that much with just a headgasket. But hks makes a 3.0mm headgasket thats the thickest gasket I've seen.

Do not install nor turbo engine 7mge?
Advice on this got into the habit.

I don't recommend 7M-GE + turbo. I prefer a full engine swap. If you must, then using 7M-GTE pistons is the best. If you can't then a 3mm HG or custom HG. 3mm will give you around 8.6 or 8.7 but having the block and head machined will remove material so your CR will be higher in the end.

A thickness of the stock which a gasket in the engine 7mge and what is the 7mgte? Someone has changed the gasket? Can compete thickness? Please.

cre 01-09-2012 07:05 PM

The stock HG thickness (once installed) is 1.27mm. GE and GTE are the same HG.

Prompt please, what better head bolts, are they? http://www.horsepowerfreaks.com/part...ro_Series/1378
And what is the pin? Prompt please, what better head bolts, are they http://www.horsepowerfreaks.com/part...ro_Series/1378

And what better and more reliable seal in the 500 hp this http://www.horsepowerfreaks.com/part..._Gaskets//4822, probably 2.0mm or this http://www.horsepowerfreaks.com/partdetails/HKS / Engine/Head_Gaskets/Metal/1308 3.0mm

Studs allow for greater higher clamping force and greater accuracy when torquing. Studs are my main recommendation when it's possible.

Head gasket thickness is going to depend entirely on your planned build and how much machining must be done to the head and block... I cannot advise you on that. Stopper headgaskets offer absolutely excellent sealing even under very demanding circumstances BUT they require incredibly accurate machining and a VERY low surface RA on both head and deck... failure to meet this will result in failure. Bead type head gaskets are generally more forgiving and are the more common type. They're not as forgiving as composite but hold up extremely well as long as everything was prepped well and the required RA is met as well. Cometic makes the most forgiving bead type HG if you cannot be certain of the surface RA being below 20. Any type of metal HG will suffice as long as everything is done properly.

Thanks for the advice, it is very useful information. :)
