Pro-Series IDA Throttle Body Kits

IDA Mounting Orientation:

There are rotary manifolds where the wide bolt spacing on the IDA flange is closest to the engine block. On others, the narrow bolt spacing on the IDA flange is closest to the engine block. 

 

If you are buying an IDA throttle body, and you already own a manifold, you must choose the correct orientation to ensure we send you an IDA throttle body that will fit your original manifold

Choose Your Manifold Type:

*** Note if ordering a manifold with your kit the rotary manifolds have the wide bolt spacing toward the engine***

We can supply the manifold to fit your new IDA throttle body to your rotary engine.  Please ensure you choose the correct manifold to suit your engine.  If you are not sure, contact us before you make your selection.

Choose Your Vacuum & Oil Fittings Option:

Vacuum Fittings - Ports to allow you to pull a vacuum signal from your manifold to use for your fuel pressure regulator or as a MAP input to your ECU.  This option is machined into the manifold, and is only available if you purchase your manifold from EFI Hardware.

Oil Fittings - This option is machined into the manifold, and is only available if you purchase your manifold from EFI Hardware.

Choose Your Injectors:

If you don't already have injectors, you can buy a set with your IDA Throttle Kit.

Here are flywheel horsepower ratings of each injector flow rate based on a naturally aspirated engine.  For boosted engines please contact us to discuss:

All ratings are based on 3BAR of fuel pressure.

4 x 550cc   = 221HP on Pump Gas / 170HP on E85 Total Engine Power

4 x 646cc   = 300HP on Pump Gas / 230HP on E85 Total Engine Power

4 x 1000cc = 450HP on Pump Gas / 340HP on E85 Total Engine Power

4x 1650cc = 360HP on Methanol (Race Use only)

If no injectors are supplied the fuel rails will be supplied to suit Bosch EV14 half height injectors

NOTE; Injector Connectors are not included please go here   to find the right connectors.

Choose Your Manifold Gasket:

This refers to the gasket between the intake manifold and the intake port face on your engine.

Linkage Option

Standard cable pull

Add drive by wire.
An EFI Hardware Drive By Wire actuator is bolted to the throttle body, linkages and electrical connector are supplied.

Make sure throttle body orientation is correct as fitment may be and issue.
If you are unsure if DBW suits your application please contact us or your tuner for further infomation.

Please note: EFI Hardware will not be liable for incorrect fitment or application

Fuel Plumbing Kit:

Fuel Plumbing Kit - Braided Hose and Fittings

4x Speed flow -8ORB to -6AN port adapters & 2 -6 90 degree fittings assembled with 400series Hose

Fuel Plumbing Kit - Rubber Hose and Fittings
4x -8ORB to 8mm barbs.  250mm of Gates Barricade rubber hose and 4x hose clamps

.

Throttle Position Sensor Option:

No Throttle Position Sensor–                                          No sensor fitted

Premium Contactless TPS                                          Variohm Contact less TPS

Bosch Style TPS CTS Brand with Plug                 Standard Bosch style TPS

You will need a Throttle Position Sensor to run your engine on any engine management system.  This throttle has a standard 8mm D drive on the throttle shaft and 32mm PCD M4 mounting holes.  You may already have a TPS that will suit.  If you are unsure, you should include this option with your purchase.

THROTTLE BODY ORIENTATION:

The mounting flange on IDA - Rotary manifolds can be configured in 2 different ways.  It is vitally important that you tell us which way around your manifold is configured to ensure we supply an IDA throttle body with the correct TPS location, cable actuation and opening direction. When ordering online please add this information to the comments section.

Check out the diagram below to confirm how your manifold is configured.

Fuel Pressure Regulator Option:

• No Regulator

No Regulator will be included 

• Include 3 BAR Regulator

A 3 BAR fuel pressure regulator with a -8 ORB screw on housing will be supplied (pictured below)

Include 4 BAR Regulator

A 4 BAR fuel pressure regulator with a -8 ORB screw on housing will be supplied ( pictured below)

QUALITY ASSURANCE:

Every single throttle bore and throttle plate are measured and matched as a pair to ensure the most perfect throttle fit and consistency across every EFI Hardware throttle body.

EFI HARDWARE TAPERED BORE OPTION:
 

Our customers have experienced consistent torque gains using Tapered Bore Throttles over traditional Parallel Bore Throttles without a loss in engine power.  This creates even more torque under the curve for better acceleration throughout the rev range of your engine.

EFI HARDWARE EXTRA FLOW RAM TUBES OPTION:

EFI HARDWARE PRODUCE 6° THROTTLE PLATES:

In the past, 12° throttle plates were the industry standard.  The problem with 12° throttle plates, is that as the plates are moved off the closed position, the change in airflow is huge.  It makes it very difficult to drive smoothly at lower throttle openings.

At EFI Hardware, we only use 6° throttle plates.  This improves off idle and cruise driveability making your vehicle far more enjoyable to drive.

BOOSTED VS NATURALLY ASPIRATED:

We have lip seals behind the throttle shaft bearings to stop grease from being sucked out of the bearings under high intake runner vacuum. These are turned around on boosted applications so there is no boost leakage and also stops the bearing grease getting evacuated from the throttle shaft the bearings. 

We ask you if you are going to run your engine Boosted, or Naturally Aspirated so we can install the Lip Seals in your throttle bodies in the appropriate way to suit your application.

We now recommend and use SKF bearings.
