It seems like ITB's are all the rage with our air cooled sixes.
The throttle bodies are either PMO or direct to head either with butterflies or AT-Power with no butterflies. Mark dug up some of the pricing!! Thanks Mark!! X-Faktory uses Megasquirt, Link or Motec M84 https://www.x-faktory.com/uploads/6/3/9/3/6...efi_systems.pdf Starting at $4754 Clewett uses TEC https://www.clewett.com/index.php?main_page...dex&cPath=2 Starting at $8400 Rasant uses exclusively Motec, which is the most expensive https://rasantproducts.com/collections/mote...84-ecu-packages Starting at $5700 for the ITB's and $6200 for the EFI AT-Power offers throttle bodies without butterflies, but use special cams to optimize https://www.atpower.com/ Starting at $13K Lots of options which can raise or lower the price. I have a stock Euro 3.2 with DME that does run fine, but I miss the sound of the webers, but I don't miss the hassle of webers, cold start, poor gas mileage, etc. I know ITB's are expensive, but option 2 at X-Faktory is not that bad and pretty popular over on the Pelican 911 technical forum. Anybody on this forum have any experience with any of these toys? |

Honestly, I'd love a way to run 3.2 Motronic—complete—on my 2.2.
Suspect the runners would be too big, and the chip would need "minor" revisions, and that there would be other issues—but one of the things I don't like about aftermarket setups is long-term parts/support. I'd hate to be in a 2020-2040 version of maintaining a 386 or 486 to run an old race car. No thanks… But I'd also love to move on from carbs. |
