gazzi123 Posted December 5, 2010 Share Posted December 5, 2010 A random question but when people do Na -T conversion headgasket is changed for compression - if you changed headgasket to a thicker one only (without any other mods) what would it do to performance or would it do nothing to benefit the car? cheers Quote Link to comment Share on other sites More sharing options...

It would reduce the compression ratio and would reduce the performance. Quote Link to comment Share on other sites More sharing options...

I think he is saying add a bigger hg when adding a turbo to a NA to lower compression instead of the Tt piston change way of lowering it Quote Link to comment Share on other sites More sharing options...
Nic Posted December 5, 2010 Share Posted December 5, 2010 Fitting a thicker head gasket is a very crude way to reduce the CR and will effect the squish pad. See post 8 HERE for a good explanation of what the squish pad is. Quote Link to comment Share on other sites More sharing options...
davej705 Posted December 5, 2010 Share Posted December 5, 2010 I agree,a better way would be to fit tt pistons if going NA-T route. Quote Link to comment Share on other sites More sharing options...
