90% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.
Nippon Racing Japan piston kit.
With an advancement in automobile technology, higher quality/performance has been required for automobile component parts. NPR products are used in all kind of engines with high quality backed up by proven technology and an abundant lineup.
Nippon Racing Japan products are all made in Japan by the highest standards and with the best production methodes available.
Most JDM Nippon Racing Japan products are made in the same factory in which large car manufacturers (including Honda) also buy their OEM parts from.
That is why many people from all over the world choose for Nippon Racing Japan pistons, instead of for example OEM Honda pistons because they are much better priced and have the same high Japanese quality.
Nippon Racing Pistons are made using 2618 alloy and a proprietary centrifugal spin casting process.
As well as a 6 step heat treatment process to insure a piston as hard as many forged pistons, but with a mush lower expansion rate.
Meaning that they will out preform OEM pistons by as much as 300% with prolonged engine life.
Teflon Coated Skirts Reduce Horse Power Robbing Friction and Piston Slap
Less slap = less noise, less cavitation (or liner pitting) and means longer cylinder liner life.
Teflon is the slipperiest material known to man. With a film of oil on the Teflon we now have a very smooth riding piston in the liner
These pistons have Holes in the wrist pin bosses to improve oiling and superior lubrication.
40 Percent stronger than OEM Honda cast pistons.
Wrist pin center to dome height has been matched to within .001"
Dome displacement has been matched to within .005 CC
This results in near identical cylinder compression, yielding more horsepower and better efficiency.

- The difference between P30 and PR3 pistons is that the PR3's are used in the first generation B16A engines in Japan, Europe and USA (B16A1 in europe) and the P30 has a higher dome, wich results in a higher compression ratio (about 0.2+) and are being used in for example the JDM gen 2 B16A engines.
