Okay I think i have my distributor figured out so here is another question. im putting together a ls/vtec in my 94 integra ls, the head is from a 2000 si that has 1000 miles on it. iwas thinking of using the si pistons on the ls rods to boost compression and i was wondering if the injectors are any different and which would be better to use? thanks

 

The plugs for the injectors are different so unless your changing the plugs on your harness your using ls injectors. I think theyre the same except for age.

To put an si piston on an ls rod you have to shave it where the rod fits cause its smaller on the b16.
