Idle: not too bad, a little bumpy, and every now and then almost dies, but the computer saves it every time. Sorta gotta pay attention and keep the revs up, but at a 30 second stop light, it might significantly drop between 1-2 times. Traffic isn’t too fun, but it’s manageable.
Running rich: doesn’t seem too bad, got a faint whiff a couple times of exhaust, but it doesn’t seem too bad. Only time will tell.
MPG’s: seem to have gone down a bit, of course I had my foot in it a lot…
Power: added good power. On the butt dyno the gains were very good, but not overly impressive. Of course it isn’t a turbo or SC, it’s just cams. But if I’m not mistaken, the butt dyno only feels torque. The low end seems the same, with the midrange improved some. It definitely pulls harder on the top end, but by how much I’m not sure. I’d like to get it to a dyno soon…
Miscellaneous: The car seems louder, but it’s not a big deal.
Overall: I’m very happy with them so far. Driving takes a little more attention, but it’s not too bad. I figure this puts me in the league of stock to slightly modded b18c’s, which is pretty damn quick for a street car that is 12 years old.
Do you think you could fix the idle with dyno tuning the gears? I was considering the 404’s but I keep hearing stuff like this with the 403’s. I don’t want the car stalling on me at lights but it’s hard to pass up another 5hp for the same price you know?

I dunno about fixing the idle with the gears and dyno tuning. Right now they’re only at +2,-2 it still comes close to dying every once in a while. At 0,0 the idle would probably be much better, but then you don’t get the added midrange that the gears give you. Now that I’ve experienced the 403’s first hand, I think the 404’s must be an almost stricly race cam. The idle on those must be just terrible. But I have heard of some people liking the 404’s, so I dunno…
G2Integrity: I am not doubting your opinion but do you really think you are running with gsr’s stock or even slightly modded now? I only know of the 403 cams done to your car but what else? I always thought it was real hard to gain 30 hp with non-vtec cars going n/a with bolt ons, I am obviously wrong but please explain.

Well yeah, I won’t know until I run my car in the 1/4 or line up against a GS-R. From dynos I’ve seen, I’m probably putting out about 135-140 whp and 110-115 ft/lbs of torque at the wheels. Now again, I can’t confirm this, but I d want to go to a dyno soon. Those horsepower numbers are roughly equal to a stock GSR, and the torque is about 5-10 ft/lbs better. Then you figure my car weighs about 100-150 pounds less than a GSR and it should be quicker. But then if the said GSR bolts on a few things, it might be about equal. It’s hard to say though, there are so many other factors that go into it. As far as gaining 30 horses from bolt ons, figure about 10-18 from i/h/e and about the same from the cams. All very subjective though.
first off, good job on the purchase. i heard 403s are great but i think you get the springs/retainers but there is a guy on here who runs them with stock but he adjusts the valvesprings every week or so. and im not doubting you but i think GSRs puting atleast 150 to the wheel stock. and if they throw on a little something they can get 160 ez = 14sec run. but like you sed once u get it on the dyno youll know for sure. keep us posted
Originally posted by G2Integrity Yeah, I’m sure some GSR’s put about 150 to the wheels, but I’ve seen a dyno of one putting out 133 whp and 105 ft/lbs of torque.
Hey,
So thats what you did to ur ride. What is the stock whp and wtq numbers? I’m just trying to figure this all out becuase I’m going to be getting the 403’s too, but want to know what I’ll be gaining or how much I’ll be gaining from them.
Originally posted by G2Integrity I’ve seen a stock 1990 b18a dyno at 112 whp and 108 w ft/lbs of torque. Seems like an accurate baseline…
Daym,
Thats kinda depressing. But tell use what you get when u dyno yours. I’m curious about how much output to the wheels you get from the 403 cams. You have all stock right? NO intake, no header, no exhaust??

Horsepower is all up top, racing is all done up top. Put 2 and 2 together. Torque is good, but horsepower is really more important in racing applications.
hehe why not get more horsepower if you can get it? I don’t understand TIroneous’ comment. Why not get more horsepower even with the torque you have? What? Are we gonna just sit there and not do a thing? Might as well increase horsepower.

well it depends on the kind of racing you are doing… Right??
if you are road racing then i agree however, if you are drag racing then torque is a big factor…
