The RHD setup (I run one) is by far the most economical way to convert to EFI/ITB. Because the system is modular, the price is much lower. While this may upset some purists who don't like the more modern look of the RHD set up, functionally it's no different than any other ITB set up.

One of the drawbacks I found with the RHD set up, is that balancing the individual throttle bodies is much more difficult than on other systems where the throttle bodies are not modular. There are so many linkages and nuts and screws and bolts with the RHD ITB's that it just takes more time and more precision, but it's not impossible and if you're focused, it's readily achievable.

If economics is a priority, then you will have to budget more time and energy to make the system work. If you don't have time energy or the capacity to work on cars yourself, then I would suggest saving up for a more turnkey solution from AT power, JSR or PMO.

All in all you can build an EFI/ITB RHD Megasquirt system for probably about $4k or less.
