First of its kind new product!
Electronic ITBs for your classic air cooled Porsche engine! Computer CAD designed and optimized, custom CNC 6061-t6 aluminum adapters with electronic throttles.
Inner and outer intake runners are CAD modeled to be 99.995% equal in chamber volume.
In stock ready to ship!
Now with BLACK anodize coating
DOES NOT include pictured PMO style intake kit or pictured injector dynamics injectors. These or another intake setup is available on request. No charge for the adapter part for using this style intake. Just let me know what setup you want. Trumpets or other filter setups available.* 964 / 993 style system (3 bolt intake) now available
* Turbocharging? Matching water to air intercoolers with inlets and boxes now available - see my other listingsDyno of my car - 1977 2.7 911 engine (non S). Stock was only 150hp. 164whp = 193hp at the crank! That's over 40hp gained with ITBs, EFI conversion over CIS. No other mods to the engine (stock internally)
Will yield huge gains on built and larger displacement engines!
Two adapters and Used, cleaned and tested throttles sets are INCLUDED.
Also includes:
2x Gaskets from throttles to adaptersFull set of stainless steel installation hardware with jet nuts for lowersUsed fuel injectors and fuel rails (new and custom sizes available)Wiring instruction for throttle motorsFuel quick connect adapter infoBasic settings for EFI settingsElectronic ITB advantages:
* Large 47mm throttles (ALSO available 49mm) can be tuned to any engine size* No linkages to adjust, maintain or install. Cleaner, less crowded engine bay* Works with any modern programmable EFI (Recommend Motec)* Far better driveability over cable ITB or throttle* No idle motor required* Easily add cruise control* "Soft" Rev limiting* Torque reduction traction control* Rev match, launch control, flat shift, and sequential gear box integrationThere are no disadvantages over a cable / mechanical setup. Get some modern tech with vintage flare and sound on your air cooled Porsche!
These should fit any air cooled Porsche engine with two bolt intake mount (Until 964) Please ask if you have any questions. May not fit with some AC compressor without some changes (seems to fit early, measurements available on request)

Toyota / Lexus 90980-11858CALIBRATION FOR MOTEC M1 SERIES ECU:MoTec M1 Throttle calibration procedure (without disassembly):* Key on
* have throttle pedal already installed and calibrated
Open initial setup 2 and open throttle settings tab
Change power save delay to 10000 sec or some long time
enable throttle test static test (throttle test window at bottom of throttle tab)
Press throttle pedal to exit power save mode
Drive throttle position with test to 0% (you may need to go to a different value first then back to 0%)
Quick calibrate (q key) Throttle positionsensor main offset
Drive throttle position with test to 100%
Quick calibrate Throttle positionsensor main scale
Drive throttle back and forth to 0-100% to check operation.
Now we need to force the throttle motors to go as far as possible! This is criticalfor idle etc.Take the LOW (main offset) value andgo LOWER to try and move the throttle further closed. So if it's 0.5V, try 0.475
After you make the change, you'll have to reset the ECU, and then touch the throttle pedal again to get out of power save mode.
Drive the throttle to 0% again. See if it reaches the specified LOW value. You can watch the value at throttle position main voltage.
Continue this procedure until you get the value for the throttle totally closed. Enter this value as main offset. Drive throttle again to 0% and it should read 0% position and your value. Press Q key on main offset to auto calibrate the value and apply it to the tracking values.
Now, do the same procedure with the full throttle setting (main scale) this time driving to 100% until you get the highest number possible. Again, after you get that, quick calibrate to apply to tracking values.
Repeat for the next bank of throttles.After you're done, power up and check that throttle aim and position tracks pedal input for both throttles.This should be done BEFORE any throttle balancing or idle tuning etc. Left and right banks should have pretty even lambda reading when running.
*****
Alternatively, you can do this procedure easily manually if you have the filter / inlet assemblyoff.
Manually move the throttle completely closed with your hands, quick calibrate main offset, manually hold completely open, calibrate main scale.
