First off, 10psi of airflow would demand about 20% more from the injectors than they can actually flow. That alone will kill the engine from running so lean. SEcondly, even with an intercooler, you are simply cramming too much air and fuel into the cylinder and peak cylinder pressures/temperatures will exceed the flash point of gasoline. This will lead to preignition, which is even worse than detonation. Pistons will yield, parts will fly and the engine, undoubtedly, would die a sudden and catastrophic death. I've done the math, cylinder pressures with that much air will simply set a stage for failure. In my calculations, 6psi was the max that one could see unless other measures were taken such as very high octane fuel, aquamisting, better intercoolers and colder plugs. Even then you would have issues with running any more than 7-8psi. That leads us back to the original problem too, the stock injectors simply cannot flow enough fuel to keep up with the demands of that kind of airflow. Even if you put TT injectors and a TT ECU in there, ignition timing for that kind of airflow is going to be about 7 degrees too far advanced. Think of taking your CAS and advancing it 7 degrees on a TT and try pulling a 1/4 mile pull. You will coast through the traps, having melted/broken a piston or two at about the 1000' mark. The reason we have never seen a 'turbo kit' for the NA is simply because Nissan never intended for it to be turbocharged. They built the car naturally aspirated with everything squeezed to the ragged edge. Very few 'base model' cars run 10.5:1 compression ratio.. The NA was an afterthought for Nissan, designed specifically to boost sales.. :
: : What all is included in the 'kit'? Just putting turbos, manifolds and piping alone is not sufficient. Do you remember me talking a long time ago about putting turbos on my NA engine? Want to know why I didn't go that route? Well, for one, it seemed like a bad idea based on the sole fact that the engine is 10.5:1 compression and the combustion chamber design sucks balls... It is no grand national engine, although I am fond of the VG. This problem makes it much more susceptible to detonation. Add to that the NA injectors dont flow much fuel, there are no provisions for intercooling and I am suspecting that an ECU is not part of the kit, you will certainly have a disaster on your hands. Neither the NA nor TT ECU have the proper mapping to handle boost with such a high compression ratio. It will not get enough fuel and the ignition will be too far advanced for proper combustion. If it doesn't come with an ECU, is it intended for those who are planning to use some other aftermarket engine management system? I also doubt that JWT has a program for such a beast - probably with good reason too.
: : Going the route of putting these turbos, or any turbo, on an NA engine I'm sure is possible. Getting into boost safely is a whole 'nuther ball of wax that even I, the infamous Fab Whore, with all my resources and knowledge, shudder at the idea.... :-)
: : *hmmm.. now If I can just get my head to fit through the door...

: : : The design of their custom kit is simple as you can see...No intercoolers needed (but they can be added as well at extra charge) and no needs of oil feed lines for the turbo is required.
