Lucas Petrol Injection

Share this page

First YOU can build a 205 HP turbo-charged EFI system with for less than $2000. Why would anyone spend more for less? More details at my web site:
https://www.turbo-tr6.info

Next I have a fully operational Lucas PI system that is available. Photos of the installation is shown on my web page:
https://www.turbo-tr6.info/tr6_engine_PI.html
I was planning on selling it later this year on e-bay but might be motivated to sell it earlier.

Finally - Know what you are getting into! Potential Lucas PI problems are listed on my web page:

Hope this helps

Hi Lee,

I was very impressed with what you built for your TR6. I'm not sure I'm ready to tackle a fabrication project of that magnitude, but I have to admit in a 'blue sky world' it has a lot of appeal, just like the supercharger setups being offered by Moss and others.

Thanks for the great insights into the Lucas PI, I can certainly see why you took a different path.
 
Hello Lee,

if your engine is non standard then you have to do a bit of adjustment to suit. The P.I. unit can be set to physical dimensions as far as full rich by measuring the gap between the shuttle and the fuel cam once the total travel is set.
There is no cold start adjustment at all, that is determined by the cold start cam, the screw you were talking about is set to have a 6 to 8 thou clearance, that's it. I note that the page you copied was for a 10" Hg idle, later units ran much higher.
Also the pressure either side of the regulator is not the same as excess pressure is dumped back to the fuel tank, if the pressure is equal then you are not dumping fuel due to insufficient pump capacity.

Hello MichaelottiTR,

just for interest, here's a set up on Uk E Bay #260029408729,
currently at ÂŁ30.0. Check out overhaul prices here:- https://www.prestigeinjection.fsnet.co.uk/pricecarg.htm

Depending on how much you can do yourself determines the price.
If you have a standard engine then you can set up the P.I. system with just feeler gauges and a variable vacuum source. I have used a Mityvac pump with a vacuum gauge to set mine.

Thanks for the info, I'll keep an eye on it. Prestige Injection is one of the places I contacted concerning a complete system, but they haven't replied so far.

Wow, lot's of great input on this topic - guess I need to step back and try to digest it all. Please keep it coming, I'm learning a lot here! /ubbthreads/images/graemlins/thumbsup.gif
