Products Shipped in a Timely Fashion
Nobody likes waiting long to receive their parts. In the world of N54 tubular turbo kits it seems that every kit is built to order and comes with wait times ranging from 2-10 weeks depending on how busy the shop is. Now this isn't a knock on other companies, but who wants to wait? We don't!
DOC Race identified this issue, and is currently the only tubular manifold producing company that keeps kits in stock ready to ship. They have streamlined their production processes, and allocated the company's resources in order to give the fastest turnaround time possible. Aside from extra features such as the available ceramic coating, and various turbo choices, or a freak accident, not much can get in the way of your kit shipping the same day you order it.
Why we like this Kit
The DOC race kit is a complete hot side turbo kit that comes with everything needed to replace your puny stock TD03 turbos with a large single turbo. The kit features a twin scroll design, with long runners promoting both quick spool and high horsepower.
Heat management can be an issue with top mount turbo kits. We like the included heat shield protecting the valve cover from heat radiating from the turbo, manifold, and downpipe. We would still recommend using header wrap on the downpipe, and looking into the ceramic coating service offered with this kit.
Our Experience with this Kit
We have not installed one of these kits, but according to DOC Race making installation as easy as possible was a goal. They recognize that a lot these kits are purchased by DIY'ers who usually do these installations from jack stands in their garage, so they made the manifold a two piece design to make things easier to get to.
We have tuned one of these kits, and we were quite happy with the results. The kit we tuned utilized a Comp 6267 journal bearing turbo. Now Comp turbos aren't our favorite for a few reasons, and power wise tend to leave a little on the table compared to competitors. Despite that, the kit showed some very good numbers.
Very soon we will be tuning another here locally that will utilize a Precision 6466 turbo, automatic transmission, and 93 octane. Stay tuned for those results!
If you are looking for a high quality kit, with minimal wait times, DOC Race may be just what the doctor ordered. For a limited time Boost Addictions will be offering free shipping on DOC Race n54 turbo kits to anywhere in the continental United States.
