4Piston Racing upgrade oil pump (Honda K20/K24 engines)
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.
The stock K20 oil pump is a great piece for up to 9,000 rpm bursts. Beyond 9,000 the stock oil pump starts to cavitate. Continuous duty at high rpm and in endurance racing with very high oil temperature, this cavitation can be catastrophic. Our ported pump will allow continuous use above 9,000 rpm, and we have run the pump beyond 11,000 rpm with great success. We start with a brand new OEM oil pump from Honda, disassemble and port and notch for fitment on both K20 and K24 engines. The pump is then cleaned, oiled, and reassembled. This critical part is cheap insurance for your multi-thousand dollar investment.
In a straight back to back comparison, this pump will make 3-4hp more than a modified S2000 pump.
Fits K20 and K24 Engines! For K24 fitment, you may buy our baffle, chain, and guide option.
Does not fit with K24 engines. For K20Z and K24 engines, you need to buy the fitting kit as well. (see related products)
