90% van de producten in onze shop liggen op interne of externe voorraad en hierdoor kunnen wij jouw order veelal spoedig verwerken (variërend van enkele uren tot een aantal werkdagen).
Uiteraard is het mogelijk dat een product een (onverwacht) lange levertijd heeft.
Na ontvangst van je bestelling, zullen wij je hierover informeren en bieden indien nodig eventuele beschikbare alternatieven aan. Houd je mailbox dus goed in de gaten.
Wij geven bewust achteraf voorraadinformatie over onze producten, omdat veel leveranciers geen systeem aanbieden om dit te kunnen koppelen en wij vooraf geen ''schattingen'' willen tonen zoals bij vele andere webshops, waar je helaas achteraf alsnog een andere/langere levertijd krijgt te horen dan stond aangegeven.
We willen jou alleen actuele informatie geven op het moment van verwerking van de bestelling, zodat we je niet hebben kunnen misleiden met een schatting.
Als je een product heel snel nodig hebt en je wil er zeker van zijn dat we het op voorraad hebben, e-mail of bel ons dan of stuur een bericht via ''stel een vraag over dit product'' onderaan de productbeschrijving.
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 p30 pistons are heat treated and come with a ceramic hard anodized surface down
to the second ring groove to improve heat dissipation especially with the use of nitrous.
Nippon racing p30 piston kits come with 4 cryogenically heat treated 21mm wrist pins and teflon coated skirts.
All nippon racing pistons sets are weight matched to +/- 1 gram.
Nippon racing pistons have deeper valve pockets than traditional p30 pistons to allow use of aftermarket performance camshafts up to stage 3.
These are true high performance racing pistons with a horsepower rating of 600 hp.
This kit is a floating piston set meaning they are designed to be used with aftermarket connecting rods only.
These will not work with oem honda connecting rods.
If you have oem honda connecting rods see our other listings for our press fit kits.
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.

- 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.
