Been on other US and Australian z32 sites and seems to be recent developments in intercooler pipe sizes. See link for some impressive numbers on stock turbos. Apparently IC pipe dimension can have a big impact on power. Any body tried bigger (2.5") intercooler pipes (with bigger ICs too)?

Yes big power and response gains. I just think they are way over priced.

Good point, maybe someone in the forum knows had to fabricate a set?

Speak to Steve at silverline. A trader on the forum.

A few zeds on the forum already have the kit fitted with good results.
