This fits the 3.0 liter British  Essex V6 found in TVR 3000M and Taimar cars, the Reliant Scimitar, some Marcos cars, the old Ford Capri, any other car running a 38 Weber DGAS or DGES such as 72-90 Jeeps and other conversions (I have final bores in either 38 or 42 mm).

This auction includes:
1) Two CNC machined adapter plates to fit the GM TBI unit onto the stock 3.0 liter Essex V6.  The GM TBI unit has ~44.5 mm bores but at different spacing than the Essex manifold.  The max bore that will fit on the Essex manifold is 42 mm.  So one plate has cones machined from two directions that meet in normal circular bores to make up for this.  The second plate has the mounting holes for the TBI.  The result is a 42 mm bore fuel injection setup... and even your kid knows 42 is not only the meaning of life but 2 better than a Weber 40.
2) A used (but good) GM throttle body fuel injection unit with serviceable (tested) fuel injectors.  You clean it to your liking.  This particular TBI has a convenient throttle body linkage for hooking up carb style cables.  I have installed
a pair of 55 lb injectors which are good to 214 hp when the regulator spring is shimmed up to make 18 psi (~180 hp with the stock 12 psi spring)

3) The (used) electrical connectors necessary to wire up the fuel injectors, throttle position sensor, and idle air control stepper motor.  These will be spliced into your harness.

In order to run this setup you will need:
1) A fuel injection controller.  I am running the same setup in my '73 TVR 3000M.  I am using a Megasquirt to control both this and a Ford EDIS wasted spark crank fire ignition.  (I have posted a photo of the EDIS and may be selling these too if there is any interest.)  The ideal Megasquirt is the Megasquirt 2 controller with at least the PCB 3.0... sound like Greek?  The Megasquirt 2 will control a 4 wire stepper idle air control valve and the PCB 3.0 can run low impedance fuel injectors.  You could run this swap with a cheap Megasquirt 1 but you will not have warmup idle control and you will need to use resistors in front of the tbi injectors.
2) You will probably want a wideband O2 sensor in order to street tune it.  Otherwise pay for dyno time and use a cheap narrow band O2 sensor for the closed loop idle and cruising fuel feedback.
3) Wiring.  It all needs to be wired up.

Sounds like a lot but the DIYer who doesn't mind wiring can get it up and running pretty quick.

I have a video of this running posted on youtube.  Search TBI + Essex V6

I am willing to provide some technical support via email to the buyer.


This is the last of these "kits" I intend to sell... rummaging through junkyards for used TBI's isn't a great use of my time.
