Nissan SR20DE Tomei Cams - Bumpstick Boogie - Dyno Cell

Setting the engine at TDC must be done by cranking the engine clockwise, and lining up the crank pulley's TDC mark on the timing chain cover's TDC pointer. The TDC marker on the pulley is on the far left.

The factory manual says to remove the tensioner, compress and lock it, but we decided to make a tensioner tool to keep the chain tensioner from expanding. Although making the tool takes about 20 to 30 minutes with the proper wood making tools, this little device saves about 2 to 3 hours from the normal tensioner process. Trust us: Save yourself the headache from the normal long and grueling task of removing the necessary parts just to get to the tensioner.

Place the chain block between the two sprockets and firmly press the unit so it locks the intake side of the chain.

With the block in place, finish removing the sprocket bolts and upper chain guide and pull the sprockets away from the cams.

Before removing the distributor, be sure to mark the cam journal and distributor with a punch or white correction fluid. To ensure distributor timing is correct, remove the distributor cap and mark the rotor's position. Since the engine is at TDC, the rotor should be pointing to the 5 o' clock position. Once this process is complete, remove the distributor.

With the distributor removed, the cam journals can now be loosened. Do not remove the journals until all the bolts have been loosened to free the tension on the cams. Once the tension from the cams is released, you can remove the journals and the camshafts.

Place all the journals in their proper order so when they are reinstalled, they're set back in the proper order.

Follow the factory service manual for torque sequence. The 10mm bolt will be torqued to a max of 9 lb-ft of torque while the two 12mm bolts will be tightened to 19 lb-ft of torque.
