Supertech Mazda Miata 1.8L 85mm Bore 30.5mm Comp Height 10cc Dome 11:1 CR Pistons - Set of 4
Piston Kit
For Naturally Aspirated/Nitrous Applications
For use w/ Ring Set GNH8500
Supertech Pistons are manufactured from extruded high silicone, enhanced 4032 alloy (with additional Cu, Ni & Mg) that had low thermal expansion, excellent wear resistance and higher thermal conductivity. Supertech Pistons, with this alloy, have withstood up to 42psi of boost, with alcohol, without any problems.
A two or three step forging process yields a fine structural grain which are then submitted to several machining steps in state of the art CNC machines.
Several heat treatments provide the piston with high tensile strength and evenly distributed hardness.
Contact reduction grooves are standard, and pin bores are honed and reamed for precise fit. Wrist pins are constructed of cold extruded chrome moly steel for high strength and used with wire clip locks.
Finally, the pistons receive a ?phosphate dry lubricant? coating to protect the rings against ?micro-welding? and enhance lubrication on the skirt/cylinder area.
Compression ratios are computed with .030? head gasket and .010? deck unless indicated in each case.

Testimonials
James LoweLooks like I get to be the first review for these guys. Let me start out by saying that I have had 3 other cars of a similar caliber to my GTR serviced/worked on and upgrades installed at other shops and none took the pride and level of detail that these guys did. I wish I could see all the welds on the downpipes and exhaust because it looked like artwork. Their fabricator made sure to send me daily updates and pictures which was also a big deal to me. For being an out of state experience it made it seem more like they were local to me and that I had known them for longer.
Luca HarrisTook the leap of faith on buying a set of their R35 intakes and downpipes because the price was half of anyone elses plus their car hauls a** at the track. Install went smooth and the power seems to be even better than advertised. Cant wait to get tuned in a few weeks. Their shelf tune honestly has to be 600+ hp as I pulled on a Hellcat last night. I see these guys and gals going a long ways if they can get out there and advertise. Customer service is on point paired with BIGGG savings for the winning combo.
Richard WestbrookBought a Motec and had these guys build the harness and set it up fully. Track car that received the level of attention and detail of a show car while here. Made me feel at home every time I popped in for a visit and always offered to buy me lunch/dinner. I don’t see me shopping anywhere else as they make you feel like your family.
