Deleting the is common when building a high hp S14/S15 SR20DET due to the failure of the VTC intake cam gear with upgraded valvetrain.  If you choose to delete your VTC intake cam gear on your S14 or S15 SR20, then this plug replaces the VTC solenoid.  By doing the delete, you will either have to run an S13 intake cam or use an adjustable cam gear to dial in the intake cam.  Naturally the S14/S15 intake cam is retarded 15-20 degrees.

If you want the highest level of timing accuracy, a 60-2 crank trigger gives that to you.  Completely relying on the cam for timing introduces error.  We developed this kit from the race team because we needed the most precise timing when making 2000+hp.   This kit uses a 60-2 reference trigger on the crank only.  This kit alone will run batch fire injection.  Or can be used with engines that already have a cam pickup for sequential injection.  We...

This is the crankshaft we use in our Pro Drag SR20 engines making over 2000+hp.  This crank was specifically designed for this application for strength and durability.  The factory stroke allows us to have a better rod ratio for reduced piston scuffing at high boost and a larger connecting rod for strength.  We also implemented the direct oil holes for the connecting rods.  With increased boost comes increase vibrations in a 4 cylinder.  So we increased the flywheel...
