im putting a streetported 13b in my 86 n/a and i was wondering what all i need in terms of fuel or engine management. can the stock stuff work or am i going to have to uprgade anything? any help would be great. thanks

 

shouldn't need to touch a thing, non turbos don't require upgrades like turbo applications do.

 

thats what i hoped, thnaks

 

what is the average power gain from a street port? i also have an e shaft from an rx8 and pinnapple racing six port sleeves.

 

meh, i dont think hat simply porting your engine will do you good if you cant fine tune the fuel.

 

i have a streetported 13bt. i guess my gains to be around ~30hp. but it doesnt help until around 5k rpm. and my low end kinda stinks.

 

edit: also depends on how big you go.

 

My best guess would be 15-30%, but that's just from speculation, because as jones says, depends on how large it is.

 

cool

 

how much is it to get a streetport? i've never really looked into it

 

$350 im sending mine to mazdatrix thisweekend.
