i am currently in the process of having a b20 block put into my car to go with my b16 head. my question is whats the highest compression i could still safely run a 85 shot on or would i be better off to stay with the stock internals for now i am on a fairly strickt budget at this point and wont to maintain some reliability thanks for any help i tried searching already so please dont flame me just help if you can

There is no golden number for compression ratio for a nitrous motor, while i ahvent had experience with building that type of motor most ppl seem to build them similiar to an all motor engine just with forged internals, i would recommend an 85 shot with stock itnernals that you make sure its running a fuel rich condition when you are using the nitrous
