has anyone here used any aftermarket headgaskets (mugen, spoon, etc.) to raise compression? is there any problems with them or pretty reliable. i want to get jdm type r pistons with a mugen headgasket on my gsr motor, do you think it would be a good idea??

 

bump for a good question looking for an answer to similar type of question

CTR pistons too high compression for a GSR motor? .. next in line is JDM type R pistons ..

What type Of Headgasket is best..

I didn't know head gaskets raise compression on a car. Damn let me get one now!

 

i was just searching inlinefour.com, and i all i could find was spoon, mugen, and toda...is there any other reliable brands out there. i would think with jdm itr pistons, it would put my car at around 11.5:1 cr...and thats pretty much where i want to be, but i havent ever heard any feedback from somebody using this setup...theres gotta be someone out there.

 

ttt

 

.. bump bump .. high compression headgaskets can raise ya .5 compression or so at most!! .. uhh

SOMEONE HAS TO HAVE THIS SETUP

 

Cometic makes headgaskets of differing thicknesses. http://www.cometic.com

 

I believe if your head isn't warped and the block is pretty even/smooth you wont have a problem with it.

There have been cases of failure of those headgaskets and it will seriously **** up the head and/or block.

Here's a pic of 1layer head gasket failure


not pretty

12.042422511586593 with CTR's.

11.362493622638828 with JDM ITR's.

Both are with OEM head gasket. If you want to calculate your compression here's a link. http://www.c-speedracing.com/h...c.php

 

overall, they're reliable.

 

i heard nothing but good things about them, all i heard that people suggest is to get some ARP head bolts and you'll be good....

 

so .. overall what is the highest compression somoen should go w/ pump gas.. 91-92 w/out tuning ..
and I'd be stuck tuning it right after I get these.. correct?

Those are some huge intake valves! Stock?

 

so do you think a mugen or spoon headgasket (2 layer) would be a good idea with jdm itr slugs and a mild valvetrain (type r or skunk 1's)? am i ok with oem headbolts?
