I have a T3/T4 eBay turbo kit for sale. Ive ran it on my Miata for about 6 months with zero issues.
1.6 or 1.8 manifold (I have both)
T3/T4 Turbo W/ Internal Waste gate 8PSI (VERY little shaft play)
Intercooler with piping
Blow of valve
RX8 Yellow injectors
This is almost a complete kit. You will need to buy/fab a downpipe & intercooler mounts, tap your oil pan with a -10an fitting and re piece the intercooler piping together. Its not quality by any means but if you want to be turbo this will get you there.
This is being sold as-is, Im not responsible for anything after purchase. You will get everything listed above, nothing more, nothing less.
Im asking $400 O.B.O. Shipped to anywhere in the US.
