Z1 keeps Stage 2 shortblocks on the shelf for quick turnaround times. So whether we are installing or shipping to you, downtime can be kept at a minimum.
A SR20DE and (T) requires stringent build practices in order to ensure the engine will last and perform 100% in all situations. Bearing tolerances, piston-bore clearances, journal finishes, balancing are all critical areas that demand the utmost in perfection - our experience enables us to produce the best of the best in engine builds ranging from the stock replacement engine all the way up to 1KHP levels.

Piston to wall clearance and ring gaps are set for moderate boost and NO Nitrous. If nitrous is going to be used on one of our engines you must inform us so that piston to wall clearances and ring gaps are increased accordingly. Failure to do so can result in premature engine damage.
When swapping an existing oil pan on to a new Z1 shortblock, the oil pan must be COMPLETELY cleaned of any and all metal contaminants. We prefer the oil pan be vatted and then rinsed and blown out thoroughly many times. It can be difficult and time consuming to get ALL the debris and sludge removed out from underneath the baffles and in particularly in the side chamber. Dents in the bottom of the oil pan can also cause oil starvation and engine damage. There is only a small space between the bottom of the oil pick-up tube and the floor of the pan. A dent in that spot can cause serious restriction in the amount of oil the pump can pull from the pan. Z1 Motorsports will not be held responsible for any damages to a Z1 shortblock due to oil starvation or contamination. We have new oil pans and vatted used oil pans available at extra cost.
