Dude, I cannot find this ANYWHERE.

 

RPW sells DEcompression gaskets. With a gasket that is approx 0.02" we're not gonna get much smaller (which would increase compression).

I've been bugging the hell outta Dave, too, about the twin TB setup.... apparently they did the 6 cyl first and now they're working on the 4 cyl..... and this is over 2 years after I asked him about it initially. No word on release date, price, other mods you'll need (although eManage or full-on Haltek is a good guess) or anything, really....

 

doug, here they are from vision imports which is really from rpw http://www.visionimports.com/lancer_headgasket.html

eboy, id love to do the twin tb setup to, emanage would be suffiecnt to run it bc you can buy the MAP sensor for it

 

Mike - those are DEcompression. They LOWER the compression for turbo boys like you. Nothing to raise compression is listed.

It says we run .5mm gaskets stock. They offer 1.1mm, 1.5mm, and 2.2mm. There's nothing smaller.

 

doug read it again, it says that they can make higher compression ones, they jsut dont give the prices, they are probably more special order items, call them

 

All it says is:

We aren't a high compression N/A engine. Our stock is only 9.5:1, which is not very high at all.

All it says is that N/A cars with high compression can use these to lower it a bit.

 

arent those austrailian lancers two doors??? of course theyre gonna be faster! and i thought i had seen thinner head gaskets before, but i cant seem to find the site now.

 

sorry doug, must not have been the right link, my bad.

yeah of course they will be faster in their 1.8L :sarcasm:, they may be a bit lighter, but you can overcome that.

 

much smaller than 0.5mm and you might as well go the VW route and skip the gasket altogether notice that the smallest decomp gasket is more than twice as thick and you get a very small decomp effect (I think it was 0.1 CR... could be wrong). I wouldn't risk going thinner. In fact, I'll probably go thicker by the time I'm done with my engine build Bwa ha ha ha ha ha

 

what are your plans or are you keeping them secret?

 

Pistons are on the table for very near the end of the build.... but size is the question, and if I go too big and do need the decomp gasket, then I need to get an adjustable cam gear (according to RPW the gasket throws off the timing a little).

 

ah yes forgot about that, well i will be getting their cam anyways, but dont really need the cam sprocker for the stg1 which i was planning on getting.

 

well if a smaller gasket can't be had, why not shave a bit off the block? usually there's a bit to be shaven since some rebuilders will have to shave(or "deck," not too good with terminology) the block and run a thicker gasket to get back to stock compression. i believe the ralliart about to run 13's has done this.

 

Hmmm... Hadn't thought of that. But it seems like a long way to go for compression with the easy availability of higher CR pistons.... Good thinking

 

But if we do get pistons, it wouldn't be much work to deck the block, since it's already exposed...
