hey guys just wondering what i can do to get my mid and top speed pull up on a d15b vtec. i have exhaust short ram intake. do you think it whould make a difference if i got cold air intake. and i was thinking of getting my computer chipped. just tell me what you think whould give me some more hp. one more thing is their any way i can find out what year my engine is what rpm the vtec starts thanks for any help.

 

to find out year, there is a year stamp on the head just right of above exhaust ports.

to get a little more top end power you can get some head work done and install a stage 1 cam. getting your ecu chipped will be worthless unless you get it tuned and dyno'd. to see when your vtec kicks in you can install a 12v light on the wire that goes to the vtec solnoid. and when it kicks in the light will light up.

 

its hard to find parts and torque spec for this engine so i dont want to take it apart. but if i can get that info. i would like to do something like that. and were would i buy the cam and how much would it cost. would any d series cam work or what. thanks for the help

 

specs are same as the d16z6.

you will need to buy an adj cam gear also, to adj the timing.
