FEATURE / SPEC
■ Type A
Designed to best suit the stock & N1 turbos for optimum performance balance of low to mid range torque.
The Exhaust cams duration was reduced to maintain best idling.
■ Type B
By extending the duration timing compared to the Type A Poncams, both response and peak power was raised and these camshafts best compliment the mid to large size turbo charged applications.
■ TYPE R(for Stock Cat. Equiped Cars)
The Type R camshafts were designed due to popular demand from end users who are looking at upgrading the performance potential of their GTR while staying within the limits of recent street legal requirements.
Recent laws on emissions and exhaust noise was made stricter in Japan so to have a quieter car by running smaller exhaust systems raises the exhaust back pressure which greatly reduces the response and hinder performance. Our engineers then designed these Type R camshafts to suit the needs of those who need to keep such setup and benefit with performance gains.

Theme of TOMEI CAMSHAFT
Asymmetrical G-Controlled Profile
When opening the intake valve during high acceleration the G from the camshaft requires to send as much mixture to the cylinder in the shortest time possible. However if the speed is too high it can damaged the Valves, Valve Seats and Valve Springs if the Acceleration G is too high. The Asymmetrical profile design given to the camshafts will allow the Intake and Exhaust Valves to fulfill the target requirement with the wider duration and high lift without damaging the Valve System.
Maximizing the Valves Efficiency
Maximizing the Valves Efficiency
The general purpose of engine tuning is to change the torque characteristics of the engine by changing the cams duration timing and cam lift amount for maximum torque and horse power. However tuning the engine is not only based on that. When going into finer details by maximizing the Valves efficiency is not just about timing and height lift but to also maximize the intake efficiency. The high valve lift allows huge amounts of air in but at the same time it mechanically damages the valve train and gains added friction loss. Longer cam durations and big cam lifts give deliver more power at higher engine speeds but it also gives a rough idle and at low engine speeds. Tomei engineers worked hard to produce camshafts that will deliver a well balanced profile at 1.3-1.5 times more than the stock camshaft.
Every camshaft is carefully built through these production processes. Plus, strict inspection will be given to them and only the highest quality products are shipped.
Surface Coating
Surface Coating
Coating the surface of camshaft with manganese phosphate in order to protect from damage even when the camshaft has not lubricated yet. This has done by steeping press process that produces 0.5mm to 15 micromillimeter thin of manganese phosphate coating on its surface to prevent from direct contact with other metal parts while realizing smooth operation.
CNC Super Precise High Speed Grinding
The combination of a ultra high-speed main bearing and diamond grindstone is controlled by the computer. By using the same special-purpose machine as an automaker, high precision grinding is realized though in 1/3 period of time. Consequently, incredible accuracy of profile and remarkable price were realized at the same time.
Wavy Groove Finish by Oscillation Grinding
Wavy groove is curved to the cam profile surface by oscillation during cam grinding process. Oil pool that is formed on the cam profile surface reduces a friction loss and prevents locking.

BODY
Keiichi Suzuki was a NISSAN Works Team Driver as well as a mechanic, and other “JOHOKU RIDERS” launched “TOMEI MOTOR Inc”.
That’s right,”TOMEI” was created as a consequence of those car guys gathered.
Although “TOMEI MOTOR Inc.”later changed its name to “TOMEI POWERED”,
its spirit and passion has been inherited, just for more powerful and stronger engine.
In the very beginning we started of as a racing constructor of NISSAN type engines only and since day one we have produced & tuned many racing engines.
Our standard procedures with the biginning of each new engine development, is to thoroughly inspect each engine component thoroughli for every aspevt of each part after disassembling and cleaning each part.
This is our daily routine and habit.
We foumd this to be the best procedure to find and address the engines good points, weak points and it helps us to accurately re-evaluate it for its new purpose.
We then rebuild it and make it close to the original but a new stronger complete ideal balanced engine.
This is the basic procedures of our complete engine development.
We now make many complete engines of various brands and we’re not only limited to NISSAN engines.
But our procedures and goals remain the same since day one. We never neglect anyone nor do we risk taking any shortcuts as to make a better engine will always take time to forge every engine to perfection.
The end result is a complete product which has passed all these enduring processes to bring the best performance available that both we and the end user can be proud of and have every bit of confidence in our products and their cars performance.
TOMEI will keep challenging to make you satisfied.
Thank you very much for your continued support
