I'm working on the design of the headers now. I have thought about just dumping the full flow into both port, but first I want to see if I can come up with a design that would allow me to direct the flow to just one side, up to a certain point, and then to both sides at higher RPM levels. This would decrease lag, but I'm not sure what effects it would have on the turbine. I would think that as long as the other port was blocked, the gases couldn't backtrack.

One of the ideas that I'm working with is using wastegates to control the flow to the second port.

Ricer: from the latin word Ricarius meaning to suck at everything you attempt

A person who makes unnecessary modifications to their most often import car (hence the term "rice") to make it (mostly make it look) faster. The most common modifications are (but not limited to):

- Huge exhaust that serves no purpose but to make the car louder
- Large spoiler on the back that looks like something Boeing made for the 747
- Lots of after-market company stickers they don't have parts from, but must be cool
- Expensive rims that usually cost more than the car itself
- Body kit to make the car appear lower, usually accented with chicken wire
- Clear tail lights and corner signals
- A "performance intake"- a tube that feeds cold air to their engine usually located in areas of excessive heat (behind or on top of the engine)
- Most of these riced cars (a.k.a. rice rockets or rice burners) are imports; Honda Civics, Accords, Integras, CRXs, RSXs, Del Sols Mitsubishi Eclipses, Lancers, Subaru Imprezas, however there are some domestics such as Chevrolet Caviliers, Dodge Neons, Ford Focus; small, slow, economy cars designed specifically to go slow. Please note that some 3000gt's Supras, Skylines, WRX's and other higher performance imports are designed to go fast, and are therefore not always considered rice, but it really depends on the severity of the case.

I meant the fact that they have billet wheels is pretty cool. From what I understand it makes them some percent lighter so you can run a bigger wheel and get faster spool than say a comparable Mitsu or GT series turbo.

Garrett utilizes that EXACT design on the new Acura RDX's. Works very well.
