Well i finally got some money to start building my new motor for my car. The only thing i cant decide is if i want to go turbo or nitrous. I'm going to build a 383. The car is going to be a street car and wanting to make about 600 hp or more with the nitrous or turbo. Just cant decide which one. Its going to be a weekend car and hit the track every once in a while. Need some opinions.

 

The question is how much money you have? A properly-built turbo motor setup will be more than $10k. If it is a really nice setup, it will actually cost you a bit more than that after all is said and done.

 

Yeah i decided im going with nitrous on this one. Maybe in the long run i will do a turbo build.

 

Nitrous will never stop costing you money, because you have to keep refilling the bottle. You're also limited to a couple minutes worth of usage before you have to fill it again.

Those two things are enough to make me never, ever consider nitrous.

 

When I was building my car I considered FI also.

At that time my car was a daily driver, and the goal was to run low 10's high 9's. To accomplish that figured I needed ~650whp. I decided on nitrous for the reason JakeRobb doesn't like nitrous......you can turn it off.

As far as having to fill the bottle....I spent $1200 on the kit and accessories
basic FI setup $5000...$40 per bottle = 95 bottles to match the initial expense of the FI kit.

 

I think one of the things I like the best about nitrous compared to other forced induction setups is the simplicity involved in the actual installation and the lower initial cost.

 

With a boost controller, you can "turn off" an FI setup too. You can also turn it down.

 

This is true, but I nitrous setup works a little better for the dual-purpose street car/track car for much less money. Remember that nitrous likes high compression, so you can build a very stout naturally aspirated motor that has a nice high compression that is also great for street driving, and then just go to the track and hook up the bottle.

I wanted my car to be an animal ALL the time, which is why I personally went turbo. To each his own.

 

I've got a roots blower deal and a nitrous car (for comparison). Both are fun, I'd say the nitrous is cheaper initially and in the long run. Additionally, the nitrous is off most of the time. I do like the idea of turning the turbo down, it's worth thinking about.

Power wise I am convinced nitrous is where it's at, also with streetability. Cam and drive train selection can easily be maximized for the street.

As an example the firebird still gets 19 miles per gallon even with the A3, is still drivable in the snow, has 137,000 miles, yet it rips low 11s in the quarter. See sig car.

You hit the nail on the head "take it to the track every once in a while."
Run a dual stage, I do, one stage for the street and both stages for the track.
