I am completing the build of a LSJ motor going into a 1986 Lotus Esprit

Upgrades include new POWER BORe Sleeves, Diamond forged 9.5:1 pistons, K1 Technologies forged rods, Total Seal piston rings, Comp Cam stage 2 cams, Supertech upgraded valve springs/retainers/valves, custom headers, larger capacity injectors, TVS, custom intake, LS1 throttle body, ATI Balancer, polished crank and cam journals, return fuel line, aluminum/steel flywheel, all running on MEFI4B controller.

Note: I am using a mechanical throttle body from an LS1 engine, as the MEFI4B cannot control an electrical throttle body

Not looking for ultimate power, just a nice reliable street machine

I have access to an engine dyno but would like to have a good starting map, as Total Seal recommends running at 2000 rpm for 20 minutes for the initial break-in. I would prefer not having to start and stop the dyno while trying to set the engine map

If you have a build similar and would be will to share you map, it would be appreciated.

forgot to add that it also has the dual pass heat exhanger

 

Looks like it will be a good combination. I can't answer your question but I wanted to verify that Total seal actually recommends running at a constant rpm for breaking in the rings? That seems strange when everything I have seen about breaking in rings they say the worst thing you can do is hold it at a constant rpm and that you should modulate the throttle, accelerate and decelerate, frequently for the first set of miles. I know total seal are gapless correct? Even being so I find the 2,000 rpm for 20 minutes procedure surprising.
