There is a racing gas station down the street that sells 94 97 100 octane gas i wanted to know the advantages of using this fuel will i get better mpg will it improve my hp just wondering kuz the 100 octane sells out here for $5.00 a gallon and thats only $1.00 extra compared to 4 a gallon
for 91 is it safe to use in a stock b18a1 with a b18c1 head and stage 2 cams

 

Do you have a stock bottom end? Just curious

 

yes i do i got the bottom out of a integra at pick and pull the engine was good just car was smashed on the back
so its the stock block stock b18a1 pistons stock rods and and stock rod bolts

 

Ok, why did you go with a stage 2 cam. Might be a little to much cam for that compression.


Back on topic though. Just use 93 octane and go get your car tuned you should see a noticeable difference once you do that.

 

i used the stage 2 cams because they came with the head when i bought it

 

nice

 

You're going to bend a valve with those cams and LS pistons.

 

how so?

 

LS pistons do not have large enough valve reliefs for VTEC size intake valves. You can get away with using stock VTEC cams because they do not have enough lift to cause an interference issue. After market cams have more lift and will most likely cause P2V contact.

 

good point, and thanks for the non dickhead answer makes since.
