Hello all,

I have been making Electronic Fuel injection manifolds for early and late TR6/TR250 vehicles, Spitfire 1500 and now TR4 cars. The basic construction is 100% aluminum with a total weight of 11.5 lbs. Included are the following features:

-Straight aluminum runners (7 inches tr6, 5 inches tr4, 5 inches spitfire)
-Brand new throttle body from a ford mustang
-integrated 3/8 NPT bung for the intake air sensor
- Bungs for vacuum (3/8 and 1/4)
- Durable powder coat finish (polished alloy or textured black)
- Custom aluminum fuel rail machined for 14mm injectors complete with Stat-o-Seals and AN6 fittings
- Custom CAD drawn flanges cut using a waterjet out of 6061 alloy with injector reliefs
-Lathe turned injector bungs cut on a mill to give an angled radius to conform to the runner
-Each manifold includes the injectors (14 lb, 19lb or 24lb depending on the vehicle)
-Each manifold kit includes the main sensors and connectors (Intake air temp, coolant temp, map sensor, throttle position, idle air control). Note the Idle air control does not have the connector since its an optional sensor.
-All sensors are standard GM so they are easily found
-Entire manifold is tig welded by hand

You will need to get an ECU, 02 sensor and the high pressure fuel system. You can trigger using the coil with points/pertronix or go as far as using a trigger wheel. I have a basic install guide for the wiring and plumbing I can send out if you send me your email.

Please remember this is a side hobby for me and each manifold takes upwards of 20 hours to make. I am not looking to argue, give away manifolds for testing purposes or spend the time or money dynoing various cars before and after so people can sift through the data. The manifold will outflow the head and factory manifolds, the throttle response will be crisper due to the injector placement at the valve, power output will increase due to increased flow and precise fueling. I cannot tell you how much because that depends on the state of your current fuel delivery system and engine. These have been installed worldwide on over 40 cars so keep in mind that I am not peddling untested prototypes.

The pictures I have attached are all of units that have been sold and are in peoples hands for months now. At the time of this post I have:

1 1972-1976 TR6 manifold in textured black $1350
1 Tr4 manifold in polished finished $1250
1 Tr4 manifold in textured black $1250

Expect to spend $700 or so on the rest of everything you need. Which I will provide links to.

To place an order requires a verbal promise of purchase and no deposit and about 3 weeks time.

Thanks

That could be a big upgrade for a US-spec car.
Great initiative to do something like this and with 20 hours work it's not as if you're going to get rich, so thankyou.

The picture links are blank for me, perhaps my adblocker.....

Ahh, I see you did, although I haven't found the opener https://forums.6-pack.org/the-6-pack-forums/parts-talk/new-products-parts-sources-vendor-reviews/541916-tr250-tr6-1968-1971-efi-manifold#post542539

Electronics... above my pay grade.. but helping to keep our cars alive.
