Good Job my friend. Love is coming to you.

The Cartech Turbo Kits were designed for SINGLE TURBO OPERATION. It was available in two different versions. The FI version, whose ducting was geometrically correct for the stock FI manifold and throttle body, and the version you are referring to, designed to blow-thru a triple carb setup via the cartech plenum. If you are planning on buying this kit, you may wish to try Jim Cook Racing in CA if they are still around. They were the last people I knew of who sold the kit and at the time, I think they were limited to the remaing supply on-hand. If you are looking for a way to pressurize your triple carbs, I'd advise against it. Carbs are not designed for changes in atmospheric pressure and that is exactly what will happen (in a BIG way) when you add boost. Go to http://www.twminduction.com and check out their 2900 series throttle bodies. They are shaped like DCOE style webers and have the same bolt patterns. And YES they take VERY well to boost. In my opinion, this is the ONLY way to turbocharge your L-motor. I'm in the process of doing the same job, and now I need to find a plenum. I met a gentleman at a show once who had 2 of them but wasn't willing to sell either. And on the twin-turbo subject... Lotsa turbo = Lotsa money.... and twin turbo means twice that! There are NO products out there for making a L28TT engine. It HAS been done but we're talking custom exhaust manifolds, custom piping, custom EVERYTHING.... If you're going to actually spend that kind of cash you might as well buy an RB26DETT (Skyline) engine from overseas. By the time you're done installing it, you'll probably have spent the same amount of money and you have the added benefit of Twin Cams, 4 valves per cylinder, variable valve timing, and a cross-flow design (another downfall of twin turbo'ing an L series engine is that both turbos, piping, AND induction components are on the SAME side of the motor.... you could always tilt the engine but after so many degrees, a dry sump oil system would be manditory and there goes ANOTHER couple grand right there) Plus the RB is an inline-six made by Nissan.... I think it would look beautiful in there. Apparantly the Aussies think so too because it's purportedly a popular conversion in Australia. Hope that lengthy diatribe helped. ~ Steve
