Save your money.

don't you think that a properly staged system on a streetport would outperform the stock SE system?

For that go boost, juice, or carb.

Man please please please do not continue with this ricer B.S. Ive read 2 of your posts on accident, do you even have a license, please note that every and I do mean every fast honduh has an engine other than the d series even SCC notes that they are niothing special, in their words they are emissions and fuel economy engines, not performance motors, and you then have the gaull to say you are winning road races with APC springs, man, when you get your license and some brains come back here, challenge us after you have sold that steaming ricer trashmobile

that, plus this thread s all of his posts, of all that one of them made any sense and all it showed was that he was willing to waste sh*t loads of money on a maybe solution, he even challenges turbos saying they suck, I dont know about you but I think angela proudfoots honda would kick his *** and its... wait for it...TURBOCHARGED

a d15? LMAO!! dude you ain't even vtec maybe you should go get yourself an h22 in your car. then mybe but I say that lightly. If you were smart you'd have put in a b18b2. 145 hp 140torque. Buddy had one and it hauled ***. Now take yor little unbit for nitrous 1.5 SOHC crap bag and go get a real engine. come back when you have a b16, nah still too slow, come back with that h22, but yor front end wil be so heavy you won't win **** for road races. D15 funny, you gonna blow that real soon.

nah dude for real tho carb in my opinion is better, efi is like..user friendly a baby could put gas in tsay ok ecu g for it let it do everything, but actually tuning a car pefectly to run amazingly is the bestfeeling.

Well I have a supercharger with carb set up now. I have decided to try going efi/ecu. This will be happening in the next couple weeks, so will see which one works the best for my application, and I will post and let ya know.
My friend was nice enough to post info on what will happen. So thought Id share.
I wanted to let everyone know what new upgrades I will be doing to my 79 here in the next few weeks. Mitch was nice enough to explain whats going to happen, and how things will work. Here’s some info that he was nice enough to type out for me. I’m going efi/ecu.
Basically I am doing is a complete update to all the newest technology. I am adding a computer into a car that had very little in the lines of electronics for engine management. The biggest change is going to come to the fuel system. In the beginning there were carburetors, and they were good, but then computers made there ways into cars and along came fuel injection, and it was better. Though there are a few shuttle differences. The first major change is the fact that Fuel injection needs pressure behind the injector. This is so that when they do open for a spit second there is a burst of fuel. The spit second that they open for is controlled by the setting you put into the Microtech. Carb's use the flow of air to get the fuel into the engine, it utilizes the physics of airflow to spray fuel into the areas where airflow is the most squeezed through a smaller area. Most of fuel loss occurs in carbs going down the intake, because the fuel wasn't "placed" close to the engine block, it is just sprayed into the carb and has to run through all the intake tubing. By going through the twists and turns of the intake the fuel particles actually land on the faces of the intake tubing, which basically makes it very inefficient.
Using injectors to optimize the fuel (fuel particles floating in air) there is very little contact with surfaces, and ensures that the fuel reaches the rotors still floating in the air. Basically a vapor is more flammable than fluid is, which makes the Injector far superior.
To do this to your car the fuel systems must be to a par that it can hold 60+ psi of fuel pressure. And by stating that, you also must have a fuel pump that can get the fuel to that pressure, and hold that pressure even under a high RPM Load.
As far as hooking up the Microtech it is very easy. You wire in power for it, hook up injectors, air temp sensor, 02 sensors, and also your crank angle sensor. It is very easy to do. The Microtech also comes with it's own fuel pump relay, which pressurizes the fuel system before the engine turns on, and also maintains according to engine dynamics how much pressure is in the lines ready for the injectors to use.
You are going to be using a custom intake throttle body because of your application. This is also another bolt on upgrade to what you have. With the injectors the fuel side is taken car of, now the aftermarket throttle body is going to insure that you have a good seal on the engine for idling and precise air fuel delivery.

That's why it's used all the time now.
A good carburetor can be tuned just as perfectly as a fuel injection system...for one given set of parameters (rpm, load, temperature, etc), but as soon as one of them changes, something will be comprimised.
