Hey guys,

Gruppe-S 4-1 Headers
We finally got the Gruppe-S 4-1 Headers back in stock!! These headers work well for the 2.0 car and work GREAT for the 2.5 car. Gains of over 18 ft/lbs are seen on a modified 2.5 STI! Order yours now before we run out again! :)

$399 Shipped!!

Want to run 12's without having to run a super laggy turbo? The IHI VF22 would be your turbo of choice. On race gas with the proper supporting mods (turboback, intercooler) and a good tune this is your 12 second package. The key? The larger flowing IHI VF22 as well as the larger injectors for more fuel (100 octane):
-HELIX 660cc Injectors
Want to do it on C16 with a VF34 instead of a VF22? Add $100. Both are good in stock!

New Helix V3 Downpipes!!!

Helix V3 Downpipe for 02+ WRX / STI - $199 shipped

The Helix V3 downpipe incorporates all the popular features of the V2 downpipe with the addition of an external wastegate provision. This provision allows for external wastegate gases to be vented back into the downpipe. Helix also re-designed the bellmouth to reduce production costs without sacrificing the SS304 mandrel tubing, high quality TIG welding, etc. The end result is a better downpipe at a lower price.

The Helix Cams (great for all you Hybrid 2.5L WRX head guys out there) are finally back in stock!!!

Helix RNA Series Valvetrain and Cams- 2001+ Subaru Impreza EJ20 (non-AVCS) $999 shipped
The Helix RNA camshafts are designed specifically for high power Subaru applications without sacrificing drive-ability and streetability. The RNA cams work well on the 2.0 platform, with a minor reduction in low end torque while providing truly impressive mid and top end power gains of over 20+ whp, and truly come alive on larger 2.2 or 2.5 liter applications by providing the extra intake and exhaust that the larger displacing engines need.*
*Helix Valvetrain is recommended for Helix Cams.

Helix RNA Series Cams- 2001+ Subaru Impreza EJ20 (non-AVCS) $519 shipped
While it is highly recommended that these cams are used in conjunction with the Helix Valvetrain, they can also be used with your stock valve train (which allows for 10mm of lift).

-SPECS: 264 Duration, 9.6mm Lift,Titanium Retainers, Dual valve spring, with spring seats
-APPLICATION: EJ205 / EJ207 Non-AVCS only
-RECOMMENDED MAXIMUM REDLINE: 8500RPM (w/ Helix valvetrain and supporting bottom end only)
-This cam and valve train package in the 2.0L WRX heads w/ a 2.5L SB make peak power numbers that are actually better than many of the 2.5L STi motors that we have tuned with similar supporting mods.
