Thinking of a project for next winter or the one after...........converting a Dolomite 1850 to fuel injection.
I already have the bootlid badge
At least a few TDC members have successfully done this, Jeroen on a LHD 1850 using USA spec TR7 efi
and Stag76 in Australia on a TR7 Sprint and Paulsprint on a Sprint.
What I am interested in is improving fuel efficiency.
As a test car using CVT Tony MacKillop's R reg 1850 achieved 50 mpg (and that was with SU carbs).
This is the kind of figure I would like to achieve. With various improvements including a Type 9 gearbox
my car can manage over 40 mpg.
There is a confusingly huge amount on the internet about different conversions
so I am looking for some pointers as to which way to go please.......
Fuel tank and fuel pump?
Is it better to keep these separate and employ a swirl tank or go for a tank with an integral pump.
I quite like the latter option as it will take up less space overall and furthermore like the idea of a plastic tank.
The Dolomite tank has 12.5 gallons capacity but I would happily use a smaller one,
I am considering the Rover Mini (7.5 gal) but these are steel. Any suggestions for makes or models?
1850 or TR7? I am thinking the latter because the throttle bodies/adapters could be swapped onto a Sprint manifold at a later date.
That would mean employing two throttle bodies. Jenvey do these and HS6 adapters.
Which ECU? I am thinking Megasquirt.
What size of throttle bodies?
Is it better to have the injectors tapped into the throttle bodies or in the inlet manifold?
I have some many more other questions but think that should do now
