i have honda civic 2dr coupe d15 vtec-e i have aem cold air intake direact air funnel located in front of the filter for straight ,dc headers b16 troddle body,jet ecu upgarde,aem pulleys. stage 2 act porformance clutch,short shifter,lighter parts weight of the car is 2015 pounds it was 2369 pounds, i have stabilzer in side the and trunck and underneat the car the car is lower 2inches,i did work on the engine basically its now a stage three vtec change out the whole internals the engine was also ported and polish

what does lowering the car have to do with horse power?

I would say you got about 450 horses. Check out a dyno though to be accurate.

Vtec has stages? SOHC VTEC-E Honda's next version of VTEC, VTEC-E, was used in a slightly different way; instead of optimising performance at high RPM, it was used to increase efficiency at low RPM. At low RPM, one of the two intake valves is only allowed to open a very small amount, increasing the fuel/air atomization in the cylinder and thus allowing a leaner mixture to be used. As the engine's speed increases, both valves are needed to supply sufficient mixture. A sliding pin, which is pressured by oil, as in the regular VTEC, is used to connect both valves together and allows the full opening of the second valve.

I would say 250hp. It is a d16. Lowering the vehicle has nothing to do wiht horse power although its great for handling. As for the V-tech maybe you did upgrade the v-tech with a different ecu.

250 ? not on a d15. to get a d series to 250hp n/a takes a shitload of money and more mods then wat he named. he may get 130-180. mabye not even that

With the mods on that engine you are probably in th 140-150 hp range. And just so you know VTEC does not come in stages. and this depends on what internals were used, the engine management system settings and other variables.

You might of made stock hp rating. 130whp if youre lucky. Without a proper dyno tune dont expect much.d15 economy vtec engines are turds for one. It was wise to get header and cold air, but header is pretty much worthless with stock exhaust. Bigger throttle body is worthless without a bigger intake manifold and ported head. Never heard of jet ecu upgrade sounds like a big waste of money. Aem pulleys are a waste of time and tend to break. There is no need for a performance clutch when your putting out jack shit for power.

Your probably in th 145-155 hp range.

10-15 HP
