Lucas PI Fuel vs Triple Webers

[jeremyrgunn]

Hey everyone, I have the stock carbs but i'm looking at what everyone is using on the TR6 motors now-a-days. I know the european cars came with the Lucas PI sys but seems to be difficult to find in the states and are supposedly tempermental. So i'm looking into ideas or should i just stick with the stock carbs and rebuild em?

Cheers!

s above, or:
Triple SUs, by Richard Good,
Six Mikuni single throat motorcycle carbs.

Also, there are a number of derivative designs, similar to Webers.
DellOrto, Solex, and SK all made their own version.

Also, you could do a single TB, on a shared plenum.

My top choice is Italian Webers.

What modifications have you made, or are you planning to make? What year is the car? Does your state have pollution testing?

Best,

I don't have to worry about pollution testing, the car is a '71 vixen. I have made 0 modifications thus far, planning for spring. However I'm looking to keep the car period specific with slight modifications such as EFI etc.

If you choose to go for modern EFI, do I have ignition and fuel map's for the 2500 engine, suited for VEMS ecu. And you can quite easyly convert the original SU's to EFI. I'll find the links later, but you can get an injector kit, that fit's inside the SU, so you keep the stock apperance but get the economy and drivability of EFI.

This TR6 was converted last year

I would be very interested in the injector kit that fits inside the SU's that sounds about what I would like to see happen.

Hi Jeremy,

Any chance you could post a pic of the compensator/linkage for the carbs please?

It's one original part I'm having difficulty sourcing and I'm not too sure how it all fits together.

I've got twin HS6 SUs with K&N filters on mine at the moment. Not running right yet but I live in hope.

Thanks,

Chris

I will take a picture when I get home tonight and post it up.
