S13 KA-T kit?

do any companies make these, and also how hard is it to fabricate one?

Turbo manifold
Turbocharger
Wastegate
BOV
oil lines
Piping
Boost controller
Cone air filter

This is the basic setup. If you want more than 5psi, you are going to need either a FMU or AFC. You will definately need injectors. SR injectors work just fine. Upgraded fuel pump is also a plus. FMIC is a good upgrade.

All in all, a 5psi setup can be had for under 1k. This is very conservative shopping such as EBAY. But remember, pick one of the three( Fast, Cheap, Reliable). "Some rules can be bent, others can be broken,"

also, did nissan come out with S13's in the us that didnt have flip up lights? i never see any that do.

All S13s here had flips.

but in japan, there were s13's that didnt have flips, right?

In Japan, the S13s all had these long rectangular lights and the 180SX had the flips.
