hey everyone i was wondering why my integra gsr 4d is so slow i have v2 cold air skunk2 intake manifold and a n1 catback and coputer and im runnin 15.4 why am i having such a slow time do i have dyno it or whts wrong? please help me

 

the intake manifold isnt helping with stock internals. other than that, you have no real hp making mods.

 

the mods you have only really help the motor breathe better! if you're looking to make more power you should do a search and then ask questions if you don't understand or want to find out opinions about parts.

Do you want to turbo or keep it naturally aspirated? whats your budget? are you going to build it yourself?? etc. etc. etc. those are some of the questions you have to answer while you search!

 

Performance header, cold air intake, cat-back exshaust, better cams & cam gears, and something upgrade you fuel control (Chip or Ems) will give you 9's at the 8th mile dragstrip.

 

Alot of aftermarket intake manifolds actually make you lose power unless tuned with a piggy back or chipped ecu or whatever. If you're running a gsr and the ecu is stock, that is your main problem. There is a set of secondary butterflies inside the stock manifold. I don't know if you noticed, but on alot of dyno plots with the stock gsr manifold being used you see a dramatic drop in horsepower when vtec kicks in. It's only for a few hundred rpms. Then all of a sudden it'll jump way back up there and start making power again. The reason for this is because the secondary butterflies take a second to open up. It's programmed in the ecu to do this, for more midrange power . The skunk2 manifold is a straight runner intake manifold much like the type r manifold. They are setup for top end power. You may want to get a vafc to mess with your crossover points for vtec and change how it engages. You might have to raise your vtec point. You may also want to try a type r ecu. You just gotta watch out because if you have a immobilizer it'll cost like 200 to have it programmed to the ecu. Thats only on newer models like 99 and up I think. My old car stock ran a 15.4. It was a 2000 2dr gsr. Remember the 4dr is heavier. With better tires and an aem intake,dc 4-1 headers, spoon flywheel, and stage 1 exedy clutch it ran a 14.6. I hope I've helped
