Carter YH Choke Conversion. This is an electronic choke conversion kit for our beloved Turbos. Alleviates hard starting, poor fuel economy, washed out oil, cylinder walls/piston rings from an over rich [choked] mixture. This kit senses head temperature and regulates the opening rate of the choke for proper operation. Includes a specific designed hold in circuit that senses head temperature during 'hot' re-starts to prevent flooding. Replaces the stock choke cover [black plastic] and the internals of the stock system.

A beautiful kit, bolts right up to carburetor and the sensing unit attaches  to any top shroud bolt. $62.00 + s/h.

Carter YH Inlet Valve. This all metal inlet valve controls the fuel level with three balls. Very accurate fuel control, will tolerate higher fuel pressures w/o flooding or dripping.

Around $185 + rebuild kit.

Vacuum Advance/Retard Kit; for Dale units.

New Weber Carburetors available including linkage kits and manifold.


Weber DCOE Linkage Kit. This beautiful linkage kit will make an easy installation of your 40 or 45 DCOE Weber carburetor on a Turbo.  The kit works equally well with a standard DCOE or one which has been modified to be a progressive two barrel.  [see above].   You do not need to contend with the poor quality linkage commonly available for this install or spend the effort to try and cobble together a working linkage system.  This fully engineered kit uses the stock throttle linkage cross bar on the intake tube and stock chrome swivel link.   A new stainless steel throttle lever arm is supplied for the DCOE.  A matching billet aluminum linkage arm tightly clamps on the stock linkage cross bar.  This billet aluminum linkage arm is designed to be fully adjustable in both position and working ratio to allow for a proper installation on any engine.  $76.

Weber 2 bbl. Progressive Support Bracket.  A billet machined aluminum bracket specifically designed for  the secondary vacuum actuator on these modified progressive two bbl. carburetors.  These new brackets mount directly on the Weber DCOE and replace the bottom cover that the current sheet metal bracket is bolted to.  This stout aluminum bracket resolves the issue with the sheet metal bracket flexing and bending under operation.  This bracket also allows for the mounting the secondary housing in a slightly revised position to achieve a more linear pull on the secondary throttle shaft.  This results in a smoother and more consistent opening of the secondary throttle plate as well as allowing the secondary throttle to more accurately return to its home position and will net a more stable idle.   An easy install to all existing modified DCOE carburetors.  $65.00.  (All DCOE carburetors modified by American-Pi include this bracket.)

Weber 2 bbl. Progressive Adjustable Secondary Housing.  Tailoring the opening rate of your secondary is good practice to obtain the best match of your modified DCOE to your engine and driving style.  It is also important to note that any change in jetting to the primary side of the carburetor also most likely requires a change in the secondary opening rate to match the new primary jetting.  To accomplish this job previously required changing the spring in the secondary housing.  Although this was made easier by the use of a quick change kit, it still requires some dexterity and patience as there is limited working space between the secondary housing and the hot engine sheet metal.   

The new top cover assembly for the secondary housing allows for tuning the opening start point and rate of the secondary by a simple turn of a screw. The new billet machined aluminum top covers now allows for a suitable range of tuning, quickly and easily and gives you an simple and accurate way to fully tune the secondary to perfectly match your engine and driving style. A simple install with great results to any modified DCOE carburetor.   $80.00.

Quadrajet Conversion. This custom made adapter allows the use of a Quadrajet carburetor. on a Turbo.

High Pressure: Supplying 80 to 300 PSI at the discharge nozzle, this high pressure water injection system is unmatched in performance and efficiency.  The highly atomized water vapor can be directly injected into the boost side of the induction system and is also perfect for EFI applications.  This high pressure system can be more accurately termed a liquid intercooler and will markedly lower your intake charge temperature allowing your to run more boost and a cooler running engine.  Complete system including nozzles, special stainless steel high pressure electronic pump, wiring harness, relay, brackets, etc.   Pricing depends on system options.  Please inquire.
