Toda Racing has just launched it’s new big throttle body for the Toyota GT86 and Subaru Impreza BRZ.

Increasing the diameter of the throttle and in combination with a tapered entrance helps to increase the amount of air the engine can breathe, giving improved performance. The internal dimensions of the throttle valve diameter are increased from 65mm to 68mm, and the tapered entrance starting at a diameter of 72mm all maximum size provides an increas in area of 9%.

With the throttle controlled via drive by wire, the throttle shaft has not been modified to be thinner ; this is to increase the life of the single throttle body by retaining a more rigid shaft. To compensate for this the throttle diameter was enlarged to be the maximum possible size.

The Toyoa GT86 Toda thottle body can be reviewed and purchased here.

The Impreza BRZ Toda throttle body can be reviewed and purchased here.

We love the Honda CR-Z hybrid here at Torque Developments! We love its looks and its economy, but it’s simply not fast enough to excite. As standard the driving experience leaves us wanting more…

Hence why we’ve been releasing a range of produces designed to put more squirt into the CR-Z and the latest (and potentially most significant) is a Hondata FlashPro ECU remapping system for the funky sports hybrid.

So, what is Hondata? Based in sun kissed California, Hondata is the leading supplier of remapping software and has a proven track record in offering reliable, high performance ECU solutions for previous Honda models including the EP3 and FB2 Civic Type R, where it’s FlashPro system has become the choice for tuning enthusiasts and professionals.

What is the Hondata FlashPro system for the CR-Z? The Hondata FlashPro system expands the capabilities of the stock Honda CR-Z ECU, enabling the manipulation of key engine parameters as well as adding advanced extra features that the stock engine management system lacks, including rev and launch limiters, fuel injector scaling and individual cylinder trims and knock control.

The speed of installation and powerful functionality of the Hondata FlashPro system allows professional and hobby tuners to affordably remap the ECU to optimise the performance of mechanical modifications including induction kits, exhaust systems, camshafts or more radical upgrades for the CR-Z such as turbocharger or supercharger conversions.

Hondata Honda CR-Z users can also benefit from advanced features including the ability to swap between two maps (both calibrations can be stored within the FlashPro unit) and the facility to datalog up to 20 hours of key engine parameters.

Hondata CR-Z FlashPro key features:

• Programmable ECU interface
• OBDII diagnostic port connection
• USB 2.0 connection
• Works with laptop or desktop PC
• Live tuning capability
• 20 hours on board datalogging memory
• Windows compatible FlashPro Manager software
• Check and clear diagnostic codes
• Customizable laptop gauges
• Dual calibration storage – upload from one of two calibrations stored in the FlashPro

Hondata FlashPro CR-Z tuning features:

• Ignition, fuel, idle speed, table editing
• VTEC activation window
• MAP sensor based tuning
• Rev and launch limiters
• Map tracing  & lambda overlay
• Choice of either AFM or MAP based fuel tuning
• Expanded fuel ignition and knock tables for forced induction
• 4 bar MAP sensor support (43 psi)
• Support for larger injectors
• Injector latency / dead time
• Individual cylinder fuel & ignition trim
• Individual cylinder knock control
• Starting calibrations for intake, exhaust manifolds, forced induction & larger injectors

Priced at just £486.00 excluding VAT, the Hondata FlashPro system for the Honda CR-Z is available now from Torque Developments International Plc. Click here to buy now and find out more:- http://www.tdi-plc.com/catalog/hondata-flash-engine-management-p-19399.html

The final new teaser release from 2012 HKS range at the Tokyo Auto Salon was a new ‘Super Sound Master’ performance muffler / exhaust system for the Honda S2000.

Designed to let Honda S2000′s  owners enjoy the full vocal delights of the amazing F20C engine, the new Super Sound Master has been cleverly designed to minimise resonance and drone, making it perfect for everyday use.

The HKS Honda S2000 Super Sound Master is now available and can be purchased here

The second of HKS’s new for Honda S2000 tuning goodies that were on display at the recent 2012 Tokyo Auto Salon – a new design of 4-2-1 tubular stainless steel high performance exhaust manifold that’s designed to boost low and mid-range torque without compromising the F20C’s legendary top end power.

As with the factory exhaust manifold, the new HKS Honda S2000 exhaust manifold is a 4-2-1 design, but the key difference is that the secondary pipes on the new HKS manifold are twisted to enable them to be longer, which boosts low and mid-range torque.

HKS also reports that the new Honda S2000 ‘twisted’ exhaust manifold also reduces detonation, enabling users to run a wider spread of ignition advance to boost power even further. Combine this with a top quality stainless steel construction that’s been optimised to maximise flow and reduce back pressure, the new HKS ‘Twisted’ manifold is set to be  a must have for Honda S2000 owners!

Pre-orders for the HKS Honda S2000 ‘Twisted’ exhaust manifold are being taken now, so to express your interest please email Torque Developments using sales@tdi-plc.com

HKS has some very tempting new tuning parts for key Japanese models that debuted at the 2012 Tokyo Auto Salon!

Firstly a great upgrade package for Honda S2000 owners – a GT Supercharger kit.

Called the AP350SC-II Concept, the HKS package is specifically designed to increase the power output of the Honda S2000′s incredible F20C engine. HKS’s engineers specified the use of GTS7040 blower that ideally compliments the high revving 2.0-litre VTEC motor.

The end result is a fantastically responsive, torquey and powerful Honda S2000 that delivers approximately 350PS (345bhp) and is thoroughly engineered to the standards you would expect from HKS.

Pre-orders are now being taken for the HKS AP350SC-II Concept Honda S2000 supercharger kit, so if you want supercar performance from your S2000, please contact us using sales@tdi-plc.com for more details!

Having reduced the exhaust back pressure in part 2 of this blog, we turned our attention to minimising the intake restriction that creates a depression in the intake flow path which reduces engine performance.

Nick liked the look of the MUGEN high performance air box, and duly instructed us to install one.

As you would expect from MUGEN, the quality of the kit is exemplary and the fitment is perfect, taking approximately 1 hour to install.

Below you can see the MUGEN high performance air box kit installed on the CR-Z

Here’s the dyno chart for the standard air box and MUGEN air box, which shows a healthy improvement throughout the speed range.
