Lower Compression with our steel headspacer/gasket. When boosting a VR6 engine it is a must to lower static compression. This is easily done with a headspacer/gasket. Most VW engines can handle boost very well if they do not see any detonation. Lowering static compression is the easiest way to prevent detonation.
When turbo charging or supercharging a VR6 engine it is a must to lower static compression. This is easily done with a headspacer. Most cars that run pump gas (94 octane or lower) are best with 8.7:1 compression with boost over a 1 bar (15psi).
This three layer gasket comes complete with a steel spacer and a mk4 VR6 head gasket ½ on each side.
All spacers good for bores up to 83.5mm
Spacer sizes:
.030”
-Corrado/MK3 this will keep compression at 10:1 with stock piston
-Mk4 this will lower compression to 9.7:1 with stock piston
.060”
-Corrado/MK3 this will lower compression at 9.2:1 with stock piston
-Mk4 this will lower compression to 9.5:1 with stock piston
.100”
-Corrado/MK3 this will lower compression at 8.7:1 with stock piston
-Mk4 this will lower compression to 9.2:1 with stock piston
