... soon to be vafc hack... will be running low boost (5-7psi)... i was wondering if i will be alright with stock timing (16*+/-2)... or should i retard on the distributor 1 or 2 degrees... lemme know... thanks...

 

you should be fine, maybe retard 1 degree, runing 93+ octane.

 

I might be trying something similar soon, and was wondering about ignition timing also: SMC-450cc-7psi-91octane-stock ignition. I'll be sure to retard it a couple degrees to start off with.

 

why not retard the cam instead of the dizzy

 

im going to be running about 8psi on my setup and will have a msd btm, should i drop the timging about 1* then like .5*/lb of boost????

 

I personally wouldnt touch cam timing.

 

because cam timming is totaly differnt.

i ran stock timming at 8psi on a b16a on 92 octain no problems.

im running stock timming on my d15 7.5psi no problems. u can retard thetimming with the edizzy like 1deg but i wouldn;t go much more. also the btm i used that when iwas at 10psi 3/4 deg per psi worked great.

 

i didn't touch my timing...just retarding it w/ btm 1/2 degree per pound of boost. been boosted for over 12k miles on d16y7...10-11psi for 3-4k miles.

 

stock cam is perfect for boost. the overlap is very minimal with is what you want with forced induction.

Stock ignition timing is different. most people say retard 1 degree per pound of boost. just play with it, retart a lot then work your way back until you get the first sign of detonation. then take it back 2 degrees from that point.
