hi all ive changed many time my muffler due to police ticket now im back to basicaly stock look with a flowmaster 40 serie and my exaust line is 2 1/2(stock) for my jdm itr.

my tire are advan neova from japan but never lowered the pressure in it and the car feel lack of power in the range of 5000 to 6000 rpm and when the car is cold i heart the car runing on 3 cylinders but after 2-3 min of riding it its getting back to 4 cylinder... du you guy this its might be a sparks plugs wire problem ?
before this summer I had an injector problem caused by a ground with my injector wire causing 2 of them full open all time but ive not drived the car during it but ive made some road test to find the problem... might be ive broke anything in my engine during this short period ??


my best time at the track was 14,7 at 98 mph i know its feel stock but im not totally stock
its a 97 b18c type-r engine with like 200hp...and 4,40 final drive..

here what i got in the list

fidanza flywheel 7,4lbs
stage 2 F1 racing clutch kit(i think its dosent help my cause)
4-1 headers (dc-sport)

i really dont know what to do beause some of you running 14,3 with basically stock engine !!!

help me

 

when drag racing, your overall et may be skewed by bad launches...

but the 98mph trap speed does not lie...

you seem to have a pretty strong motor

 

14.7 isn't a bad time, at least you broke the 14's, most stock ITR's i've seen with my owns eyes hit low 15's, keep practicing your launch.

 

the Type R isn't a dragracing car.. leave that to the hicks with their mullets.

Go for a nice roadcourse, track... that takes real skill and is alot of fun! other then launching your car and zinging banging hte gears off redline.. NOT MY THING.

But in all respect, you are trapping really high. 98 should yield atleast low 14s... what was your 60ft ??

Cheers

 

it could be your launches not everbody will net the same time

 

BENT valves ?

 

bah.. he said bended...

Louie~ who says a broked timing belt will lead to bended valves.

 

With that trap speed, it seems as though your launch wasn't all that great.
