Top 6 22R/RE Proven Performance Upgrades

A clear, direct answer to an ancient question



One of the most common questions we have gotten over the years is: "What are the best things I can do to my truck (or car) to get a little more power than stock without breaking the bank or making major changes?"

Years ago we decided to create a list of proven options to answer this question for all of our friends from our corner of the car culture world. Now we've revisited this list to make sure it all still holds true, especially with new technologies. We've given it a little update and offer this list of choices which are great options not only if you're looking for a little extra oomph from your daily driver but also as solid alternatives to replacing stock worn-out or broken parts. This list includes the best bang for your buck options, and with the exception of rebuilding your own cylinder head, can be easily handled on a weekend. We ordered the list by a balance of gains, cost and difficulty of install.

After decades of building, testing, adjusting, breaking, listening to customer feedback and suggestions as well as race team feedback and suggestions, we've been able to compile this list of the top 6 best modifications you can make on your 22R/22RE engined vehicle whether it be an old-school Celica or a mid 90's 4Runner and everything in-between.


A header (exhaust manifold) is one of the best “bang for your buck” bolt-on performance upgrades for your 22R series engine. The goal of a header is to allow your engine to push exhaust gases out of the cylinders directly, which is more efficient, and to eliminate the back pressure normally created by the stock style manifold. A stock exhaust manifold is manufactured with a shared common large chamber for each pair of cylinders, while our header gives each cylinder its own equal length exhaust pipe. These pipes come together in a larger pipe further “down the line” called the collector. By making them the same length, it guarantees that each cylinder’s exhaust gases arrive in the collector spaced out equally so there is no back pressure generated by the cylinders sharing the collector. This will result in a 10 percent increase in power and added fuel efficiency if driven conservatively.
