Pre-Order you MazdaSpeed6 adapter plate and make your Speed6 all it can be!

Blow off valve adapter for MazdaSpeed3 or MazdaSpeed6 2.3 Turbo Engine.

This kit is on hand to ship. Allows you to install a Turbo XS RBV-H (RECIRC VALVE), BOV-H or BOV-H-RFL to a 2006 or 2007 MazdaSpeed6 or MazdaSpeed3 Turbo 4cylinder! This is how to get your car to hold that big boost from your boost control, it also allows you to show off that massive turbo sound of the TurboXS BOV-H-RFL

The BOV-H and BOV-H-RFL are vented to the atmosphere. These do not use the OEM recirc system. The effect of this will be such that during shifts the car will momentarily go into a fuel rich condition. This condidtion will not hurt the engine or the car. The only time this effect comes into play is during the shift period when the car expects the OEM system to be dumping the pressure from the intake after the turbo out the BOV and into the pre-turbo intake tract. This split second period will instead be dumping the pressure out to the engine compartment resulting in a short rich condition.

The BOV-H and BOV-H-RFL will result in significant increases in sound during the period of blow off of the pressureized air. Each shift that you boost before the shift nad cut the throttle for the shift period will result in a much louder sound as the air escapes the valve. The RFL version with its megaphone shape will result in a violently loud blow off that will attract attention from many blocks away. If you like to sneak in and out of the local housing complex at 2 AM, I do not recomend the RFL at all! If you want women and children to dive for cover as you go past...this is the one for you!

This plate will work on the MazdaSpeed6 and mate the properly matched TurboXS BOV-H-RFL or the the quiet version, the BOV-H. This plate is designed exclusively by TurboXS for use on the MazdaSpeed6 or MazdaSpeed3 car, and the two recomended blow off valves have been tested to work great and be the best match to the stock turbo. Aftermarket turbo's may require differant blow off valves...

Picture is not of actual kit! We have 3 units on hand, and will have more coming!

This is a universal blow off valve, but is well matched to the MazdaSpeed6 adapter plate. The adapter plate is shipping out between Oct 5th and Oct 10th. Pre order today, this is a limited supply deal!

High Perfomance Boost Controller (BC-HPBC) Retails for US $ 135

Utilizing a uniquely engineered ball/spring mechanism combine with an adjustable bleed valve, the BC-HPBC allows you to spool your turbo to full boost up to hundreds of RPM faster than stock! The adjustable bleed mechanism lets you minimize the massive boost "spike" that can occur with poorly designed ball/spring manual boost controllers.

High Performance Dual Stage Boost Controller (BC-HPDS) Retail is $269

The TurboXS High Performance Dual Stage Boost controller provides the ultimate in dual stage boost control. Two preset boost levels allow you to switch from "street" to "race" boost with the flip of a switch from inside the cabin - even while under full boost.

Standard Boost Controller (BC-SBC)

Simple, inexpensive, and effective way to control your boost level and generate more power from your engine. Bleed type boost controller allows you to increase boost approximately 12psi over your wastegate boost setting.

The DTEC-BC-PRO is quite simply THE BEST boost controller ever made. It turns your Gameboy Advance SP into a powerful Electronic Boost Controller cabable of controlling boost pressures in excess of 60psi. The DTEC-BC-PRO allows everything from simple "one number" boost control that can be set up in minutes to the most advanced closed loop, gear dependant, RPM, and throttle position based programmable boost controller ever conceived. It comes standard with 60+psi cabaple inline boost control solenoid; 45psi MAP sensor; KnockLite detonation detector and more. Advanced features include the ability to store and switch between five (5) different boost maps; scramble mode; overboost protection; "start boost" feature to speed turbo spool up; and gain control. You even have the option of adding a second solenoid (sold separately) to completely control pressure to both the top and bottom of you external wastegate for the ULTIMATE in high boost control. These are features you will not find in the $680 Greddy E01; the $655 Blitz SBC-id; the $629 Apexi AVC-R; or even the $725 HKS EVC V.

The Gameboy Advance SP is not included. While it is required to set up the boost controller you do not have to leave it plugged into the DTEC-BC-Pro.

Racing Bypass Valve -Type H Reversible (RBV-H) Retails for $189

Identical in design to our RBV-H34 with the exception that the outlet of the valve is our standard Type H female inlet instead of a 34mm hose adapter. This allows the valve to be used either in normal fashion or "reversed". Using the valve in the reversed orientation ensure that the valve will only open up under vacuum. This is perfect for your drag racing car running 35+ psi.

Racing Bypass Valve Type H (RBV-H) vents excess pressure back into the car’s air intake making the valve ideal for Mass Air Flow (MAF) metered cars where venting to atmosphere can create a "rich" air/fuel ratio right after the valve goes off. The Racing Bypass Valve Type H is CNC machined out of billet aluminum and brass. Valve operation, while louder than most stock valves, is quiet compared to a BOV that is vented to atmosphere like our BOV-H or BOV-H-RFL
