Lower Compression Head Gasket
 

Does anybody make a Headgasket that will lower the compression on a d-series, I have seen them before but I am not sure where. Thanks

Re:Lower Compression Head Gasket
 

summit racing has them

Mr. Gasket sells the D-series kit I belive.

Yes summit racing sells them the part # is MRG6225
Mr gasket makes this stackable head gasket i just ordered mine today. It cost $124.95 + $7.95 handling

Re:Lower Compression Head Gasket
 

Is that head gasket the only one I need or will I need one more?

Re:Lower Compression Head Gasket
 

Any idea what your compression will be afterwards?

Re:Lower Compression Head Gasket
 

Have no clue, cant find any details on the gasket, hopefully I only need one and after it will be like 8 to 1

Re:Lower Compression Head Gasket
 

The head gasket is stackable the compression can be lowered from 0 to 1.3 points depending how high u stack it.I just got mine today fed ex delivered it.

Re:Lower Compression Head Gasket
 

ugh, doesn't that get kinda risky hehe ;)

Re:Lower Compression Head Gasket
 

well if your pushin high compression like i would be. iwould be pushin 11.0 to 11.2 compression then say you used the gasket to the max height it lower it to 9.9 to 9.7 compression. which is safe for a turbo setup. high compression+turbo=problems

Re:Lower Compression Head Gasket
 

My stock compression is like 9 something to 1, so it would put me at around 8 to 1 something. Kick Ass

Re:Lower Compression Head Gasket
 

Yea, I know the risk of high compression... I just don't know if doing head gaskets would be best way to solve it?
Just a personal opinion I guess, no facts :)
Cheaper then getting new pistons I imaigne :)

Save some $$$ and get a thicker SCE copper head gasket from summit racing, it is only $53 and re-usable. Your stock gasket is 0.047 so I'd get one that is thicker than that, like 0.078, I think it is the right answer, unless you have the extra $1,000 to do it right... Call summit, they'll know what your talking about... SCE copper head gaskets.

You can't slack on the tuning part b/c copper or steel won't blow out like a composite one will. Too much boost on a compostie gasket = blow headgasket, now too much boost on a copper/stackable steel gasket = Bye bye pistons/rods/crank ( basiclly the whole motor ). With great head gaskets come great reponsiblity. They are your gift, they are your curse. ( that was lame...)

Re:Lower Compression Head Gasket
 

using copper gaskets require the block or head to get o-ringed (or both with a receiver grove) This can get done at some machine shops, usually costs around 350-500 bucks, but the head gasket wouldnt blow, something else would break first ;)

btw, I dont know why you guys are lowering your compression into the 8's... that is just crap. I would never go less than 9.1

Keep in mind lower compression without induction means put put put motor :)

Re:Lower Compression Head Gasket
 

i was wondering after you stack all those layers in there how far off i the cam timing going to be?

build your motor to the highest compression possible, with all aftermarket parts, then turbocharge it.
