We at DS1 Motorsports and Development are proud to announce that we are official Tomei dealers and installer. We carry the full range of Tomei's products for the Subaru and try to keep as much of it in stock as we can (this stuff moves quick). This also means that buying from an authorized dealer includes the 1-Year warranty from Tomei. The research and design that Tomei puts into all of their products is unparalleled anywhere in the aftermarket community. All of their trials for the EJ series engines are published on their website here. Here are a few of our featured products with tons of pictures.

Tomei ARMS M-7760 Bolt-On Turbo $1780.00
The ARMS-M7760 turbocharger was chosen because its size and dimension allows it to be swapped out in place of the stock turbo placement. Increasing turbocharger size usually hinders throttle response, however we have avoided this issue without sacrificing this aspect. This was made possible by carefully selecting the most ideal combination of components. As usual Tomei's kit includes all factory gaskets and necessary hardware. A bigger turbo without the lag, what more could you want?

Tomei 4-2-1 Equal Length Exhaust Manifold W/ Up-Pipe $990.00
Big Primaries and Huge Up-pipe!!! This is the best flowing header we have ever seen. All the flanges are hand ported and gasket matched. Then they are machined flat to provide a perfect seal. A three-bolt flange is used to further improve sealing at the up-pipe. All of Tomei's headers include all factory gaskets, hardware and header wrap w/ ties. It is the prefect complete bolt-on kit.














Tomei Twin-Scroll Equal Length Exhaust Manifold W/ Up-Pipe $970.00
Tomei didn’t only focus on the pipes diameter but also the design layout for the exhaust manifold. By reducing the sharp curves (at the gathering section) & long straight sections, helps minimize exhaust resistance & to increase the exhaust efficiency at higher RPM ranges. All the flanges are hand ported and gasket matched. Then they are machined flat to provide a perfect seal. A three-bolt flange is used to further improve sealing at the up-pipe. All of Tomei's headers include all factory gaskets, hardware and header wrap w/ ties. It is the prefect upgrade to a factory set-up.

Tomei Poncam 252-252 Camshafts $1440.00
The Poncam 252-252's are designed to maximize the stock port size and improve drivablilty. Since the AVCS function is present, A great amount of duration is not necessary. Of the four variations Tomei tested, the 252-252 shared same qualities as stock at the lower RPM range. As 5,200RPM as the boundary, some major power improvements were exhibited. These are hands-down the best cams you can get for stock internals.






Tomei Oil Pan Baffle/ Stiffener $390.00
One of the main causes of engine problems on an EJ20 are the bearings. The majority of the causes of these issues are due to the lack of motor oil in the oil pan (sump) and passages. Also, the lack of rigidity in the crank case is also another problem facing this engine design. Under extensive research, Tomei decided to develop a product that securely remedies these problems. This baffle stiffener will help strengthen the left and right side of the crankcase to help provide the added support with its dual structural design. The baffle design greatly aids the regulation of the oil supply.





Tomei Timing Belt Guide $50.00
Tomei Powered has constructed a beefy belt guide cut straight from aluminum with an extended length to securely apply more tension to the timing belt. This product comes in handy when immediate changes in torque are experienced by the engine, eliminating belt whip. The Anodized surface creates a smooth and precise belt track as well.












Also avaliable:
-Poncam EJ20 Type A (250-256) & Type B (256-264) $1590.00
-Individual Throttle Body System (Special Order) $8010.00

Thanks,
The DS1 Crew

are the three bolt gaskets metal like subaru gaskets or paper kind like ebay? can you get replacement gaskets?
They are a multi-layer steel not like the ebay junk and yes I can get replacements.

How much for the Timing Belt Guide shipped to Australia?
Where in Australia? The shipping is going to be the expensive part.

from my research and understanding, the headers are not actually equal length... on the tomei site it mentions that they kept it un-equal for quicker spool, etc. Is this a new version that IS equal length? any clarification would be great. thank you...
