D15b4 dual carb

Postby dualcarby » Thu Oct 16, 2003 7:52 pm

You would actually use less wiring than now. Carbs do not need an ECU to run... Plus the carbs will replace your whole intake manifold, throttle body and injectors/rail...

But you might have a problem with the distributor... carb's engines use a different dissy...

If I were you, I would stick to FI, you have much more aftermarket support for your FI setup... to go from FI to carbs or from carbs to FI is a very long process, and it will cost you a bunch, rather upgrade what you've got already. FI does respond well to cold air intakes, ram air, etc...

Since you are simply installing a dual carb and manifold on your car I think it won't be difficult. I'm not experienced in carbs but I think you need some stuff for the fuel to work with both carbs and to have them sychronized. Here's a page i found for everything related to carbs on d-series, 79 pages for reading and sure you will have some answers there: http://www.d-series.org/forums/engine-b ... carbs.html

If you want to make a write up on the process that would be great so people see how is done, being the first is always fun.
