    And how thick are they? Can they be used as Metall gaskets to lower compression on the gasoline engines?

    Don't destroy my mod man!!!!

      LOL, im not sure, it would be a case of order the thickest one and see how it fits and lasts.

        But do the group A cars not run 10.0:1 / 10.5:1 compression and around 2bar boost?

            Yes but they servicing their motor after every race! This is not very useful for everyday cars!

                They have massive IC, racing fuel (much more than 98 octane), water injection ect and above they have maybe the best hardware that on the market is according pistons, rods (pankl) and cranks!

                So the question now is: Would the rs2 crank be ok with 600-650 NM ? What is the limit?

                Can the Rs2's CRB gearbox cope with that torque?

They should hold boost! The diesel has very high CR!!!! Only prob is that a hole must be enlargen! Anyone knows more about this??

                  Maybe a BILLMAN MOD ???
                  don't forget diesels maybe have a high C.R. but the burn is progressive rather than harsh.so what's the combustion pressure.try to get a diesel's fan to kick in,it takes AGES,so it runs pretty cold,which might not make a difference at all,but......

                    Peak cylinder preasure on a 1.9tdi at 200 bhp is 180 bar. n The gasket is fine.

                        Has someone tryied the Diesel Gasket? What are the differences according the thickness and the holes?

                          Again if i used the Compressor map correct!
                          with stroker you need only 1,2bar boost to have such HP and Nm on those rpm

                            you may use 2 stk steel multilayer gasged.the holes are NOT the same.the boltholes in the diesel are 12mm i think,the petrol are only 10mm.... the bmw engines arp studs does fit i think...then you have a steering pin in the top af the block.you may bore in the gasged there to fit it
