1992 ZR1 Seems Sluggish - ZR-1 Net Registry Forums

Please do! A pair? there are two pumps? My plan is to ultimately go through the top end and replace all the fuel rail seals and fix any vacuum issues. May do some top end porting as well. The injectors are original I believe so I may upgrade those too. At the moment trying to finish up my 95 project involving changing the rear gears to 4.10 and swapping over to a light weight RAM dual clutch set up.

How do you like the 4.10 gears? I hear the lightweight flywheel can be noisy buy I added a thicker counter shaft shim as recommended by Bill Boudreau including his C-Beam plates. It has been a fun project but I am ready to get it done. Everything else has been done to it except secondary system removal. I am in the process of registering the car in a county that does not require emissions testing so I am planning on pull all that stuff out as well now.
