I have asked Greddy the same question and here is their reply:
"Thanks for your interest in GReddy Products. We are still currently working on the 240sx turbo kit. However we do not have any specific data to release at
time, not boost levels, horsepower, or pricing yet. We hope to have the kit available by mid 2002. What we can tell you is the kit will be a good bolt on street kit, that has a lot of room for upgrading. It will probably
include Cast-iron manifold, downpipe adapter, some some sort or TD06 turbo, our FCU, and all the necessary pipes and hardware, but again this is all preliminary and it may change. Please keep in touch with your favorite Authorized Greddy dealer for more updates.
