Is the stock intake a bottleneck for a street only setup?
 

I rarely rev over 5000rpm on my daily driver and was wondering if the intake is the next bottleneck on my basiclly stock motor. I have most of the bolt-ons and was wondering what to replace next.

going to an aftermarket intake on a stock engine will get you about 10HP for 300-500 bucks.

If you dont already have gears, get gears.

Later,

both the heads and the intake are "bottlenecks". I personally feel the heads are more of a bottleneck than the intake though... but with the right one you will feel a bit more umph all the way through your powerband.

oh yeah, do the gears if you don't have them already. :)

i agree with both previous post's, it is true that the stock intake isn't the best for even a stock motor, but i would obtain other things before i would address the intake such as:

1. gears
2. exhaust: catback, h-pipe, headers
3. advance timing
4. remove air silencer

then i would go on to the intake, heads, roller rockers, cam, and all the small side items (65mm tb, larger mass air, and so on)

i did mine piece at a time and acutally put a cobra intake before i did the heads and i noticed a good increase at the track 14.79 to 14.55 and i think 1.5 mph, but that was with all exhaust in place and everything and also it depends on what intake you go with. if you stick with a long runner such as the cobra, edelbrock, or gt-40 you will be ok stock, just don't go with a huge intake or short runners and you will be ok if you plan on never doing heads.

I'll add my sig here...

Just wondering what to do next...

I would go with some good aftermarket heads next with an explorer/GT-40p intake manifold.

You have already layed the groundwork for a good performing car with all of the suspension work you have done.
