Camshaft Set EJ25 D-AVCS

GSC's cams are fully machined from forged billets cores on advanced CNC machining equipment. Modification to front cam cap bridge may be required for some or all cam options.

S1 cams improve turbo spool and provide power gains across the entire rpm range without any loss in low end. Standard valve springs can be used. Suitable for up to 500whp. .

S2 cams work well with heavily modified engine setups with larger turbos, head work, and other modifications. Requires uprated valve springs (GSC beehive springs suggested for over 8000rpm).

S3 cams are for applications over 700whp with extreme modifications. Modification to the cylinder head castings is required due to the large lobe size. Uprated valve springs are essential.

Usually ships in 1 to 2 days.
