PRP Dry Sump System - Nissan RB 4WD
We have undertaken this huge project to design, develop a one-piece billet dry sump with integrated oiling components including a huge Dailey Engineering oil pump!
This is a significant undertaking that will revolutionize the performance engine industry.
The dry sump system offers several advantages over traditional wet sump systems, including improved engine lubrication as well as the key factor of controlling air contamination within the oil.
The use of the compact one piece billet alloy pan construction with self contained oil channels as well as the added bonus of voiding the requirement of external oil lines as potential points of failure, aesthetics and costs as well as modular and removable diff assembly from within the car makes track side gear changes and maintenance a breeze without the removal of the engine.
Through the use of advanced computational fluid dynamics (CFD) simulations, and consultation with industry leaders in the field, PRP has been able to analyze and optimize the oil supply and flow within the system, ensuring that the engine receives a consistent and reliable oil supply.
We have chosen to partner up with Dailey Engineering needing no introduction for an exclusive to PRP designed set up incorporating a cutting edge custom designed 5 stage big body pump + air separator which fits neatly in front of the front differential assembly, as the air separator is crucial to motorsport it has not left any room for a fuel pump so we have added provision for mechanical fuel pump on the opposite side just below and forward of the air conditioning compressor if you were to run one.
Oil mesh strainers are now sandwiched between the sump body and the oil pump allowing easy maintenance and inspection.
Not only have we gone above and beyond with the product design and manufacturing, we've made the listing a one-stop-shop listing so you can purchase everything we recommend in one simple listing. We are confident the several years of R & D has resulted in the best outcome for you, our valued customers.

Q: Do you ship to Quebec?
A: No — and we never will.
This decision is final and intentional.
Quebec’s tax structure and regulatory requirements create unnecessary friction for independent businesses like ours.
More importantly, the region has consistently demonstrated a lack of respect for authentic Japanese car culture, which is the foundation of everything we stand for.
The prevalence of replica parts, low-effort builds, and price-driven behavior directly contradicts our values of craftsmanship, originality, and pride.
We are not here to accommodate markets that dilute the culture.
We are not interested in adjusting our standards to fit in.
We do not respect all builds.
We respect those built with intent, effort, and pride — not for attention.
Trimotive is a brand for enthusiast, not clout chasers.
Quebec is not our market, and never will be.
Q: I’m building something custom — can Trimotive help?
A: Hell yes — that’s what we live for.
While our product line focuses on proven, platform-specific parts, we’re always excited to support builders pushing boundaries. Whether you're working on a custom swap, cross-platform setup, or a full-on Frankenstein project — we’re here for it.
We’re constantly expanding our knowledge base, and community-driven R&D is part of how we grow. If you’re doing something different, ambitious, or just plain wild — reach out. We’re always down to get involved, offer insight, and help source what you need.
If it’s built with intention, we want to be part of it.
Let’s bring that vision to life.
Q: Why doesn’t Trimotive accept returns and refunds?
A: Because we take our parts — and our partners — seriously.
Trimotive works closely with a network of specialized suppliers across North America, Japan, and beyond. Many of the products we offer are platform-specific, custom-built, or limited-production, and in many cases, made-to-order. These parts are not meant to be casually returned or resold.
Some of our suppliers are small, independent manufacturers — including one-man operations in Japan — who pour their time, skill, and pride into every product they ship. Others are high-volume performance brands with strict allocation policies. In both cases, mistakes or indecision on the buyer’s part don’t just affect us — they damage our relationships and affect everyone’s timelines.
We’re proud to work with companies that embody precision, accountability, and craftsmanship — values especially ingrained in Japanese business culture, and values that we fully adopt at Trimotive.
For this reason, we enforce a no-return policy on all non-defective items. We do not do this to be inflexible, but to protect the integrity or our supply chain and prioritize builders who plan, commit, and execute with intention.
We’re not here to accommodate indecision.
We’re here to support serious builds — and the people behind them
Q: Can I pre-order parts?
A: Yes — if you’re fully committed, we’ll make it happen.
Many of the parts we source come from small-scale manufacturers or boutique suppliers, especially in Japan, where lead times can vary significantly. Some items are made-to-order, produced in small batches, or even hand-built by single craftsmen. That’s part of the culture — and part of what makes them worth waiting for.
If you’re locked in and ready to go, we will coordinate directly with the manufacturer to confirm availability and timelines before we take your payment.
All pre-orders are paid in full and non-refundable, unless the estimated lead time becomes unreasonable or changes drastically. In those rare cases, we will issue a full refund and notify you immediately.
Pre-orders are for committed builders.
If that’s you — we’ll get you what you need.
Q: Does Trimotive offer sponsorships?
A: Yes — but only to builders who fully align with our values.
Trimotive sponsorships are reserved for individuals or teams who have a clear, standout presence in one or more of the following areas: drifting, time attack, drag racing, or functional show builds. We’re not interested in social media clout — we’re interested in execution, discipline, and authenticity.
We only consider cars that:
Are built with purpose, not just for photos
Use proven, high-quality parts only (no replicas, no shortcuts)
Represent a genuine commitment to the culture, not just the spotlight
If your project stands out and reflects the level of devotion we expect, reach out with a full build sheet, current photos, and a clear statement of your goals. If we see alignment — we’ll talk.
