My car is a 1981 GS RX7 that I bought in 1992. I swapped a Hayes Rotary Engineering built 4 port 13b into it in 1996. The engine is street ported and balanced, has a high pressure oil pump, grooved and hardened rear stationary gear, micro tapered eccentric shaft and shimmed oil bypass valve. I have a racing beat long primary exhaust system, racing beat intake and 600cfm holley carb. Direct fire, wasted spark ignition set up with MSD 6AL box. I am in the process of installing a 5" camden supercharger that I have had for about 12 years. To prevent detonation I am installing a water/methanol injection system and will rejet my carb to a richer mix. I am interested in any input anyone may have on my supercharger setup and any tips, esp on how to work my oil injection linkage. Thanks

 

Bought the Percy's adjust a jet for my Holley. It fits between the float bowl and metering block and eliminates the jets. Tuning is by turning a screw. Blocked off the omp, will run premix.

 

how much did that adjust-a-jet run ya? o and excellent engine choice.

 

$75 from summitracing, you need two plus a longer fuel cross over tube which is about $8.
