What size are these nozzles?

Sam Powell · 10-16-2007

What size are the nozzles that come with the progressive kit? I am running a Mopar 3.7 litre slant six with a Buick T-4 from an '87, through an unknown intercooler. I am running 9 lbs of boost currently, and can;t get past detonation with a 195 thermostat, and normal heat range plugs,with permium fuel.. ECU is a GEN VII Accel unit which has worked well after initial trouble shooting.

If I put a 180 thermostat in, and colder plugs the detonation goes away, but drivability and mileage suffer. I would like to reduce fuel, and up timing with standard plugs and thermostat, if possible. Thanks for any advice.

They wil be stamped on the side. m3, 7, 12 probably start with the 3 if i was you.

find out what the other slant 6 is using with his Buick GN turbo.. he seems to have a handle on his tune up

PS.. id try using a 160 thermostat.. your ecm should still go into closed loop at 160.

Sam are you doing you own tuning on the GEN 7
