Well, I've decided to haul the black mk3 tina out of retirement, but I think its time that the 2.1 pinto was retired, or at very least the 38DGAS needs to go. Its not that the car doesn't go well... more like it goes really well but you have to stop for fuel infuriatingly frequently. So, whatever engine goes in will be injected so I can get the most out of the fuel its (still) going to drink.
Current choices are...
Pinto EFI manifold onto the same engine, sierra ECU
2.0 zetec on either standard management (EECIV, no PATS) or a megasquirt
2.8i cologne (K-jet, no ecu)
2.9 24v cosworth BOA again, either standard (EECIV) or megasquirt
I'm tending towards the zetec for the best blend of power and economy
But before I can do that, the car needs some plumbing. Cortinas didn't come with fuel injection so its time to sort out a suitable pump/swirlpot etc. There are a number of ways of doing this, of course. My mk2 has a sierra swirl pot (plastic box!) inside the tank, and a capri pump and filter underneath, between the tank and the axle in the same manner as a capri or sierra injector does. Its a good way of doing it, but the external pumps are getting hard to find in the scrapyards, and cost a small fortune to buy new. I also don't have a spare one since the pump casing burst on the polo and I needed one in a hurry to get it back on the road.
I also have a golf swirl pot laying around, but as this is gravity fed it needs to sit below the bottom of the tank to work, and cortina tanks are pretty low. Better suited to my mk1 capri, that one
There are "other" solutions too, involving lift pumps and external swirl pots, but I don't like extra complexity and would rather use a "production car" style solution if I can. So today I......
cut the fuel pump mount out of the top of a granada scorpio tank. I did first check to see if the whole tank would fit under the back of the half-tina autofive has left half cut up in the corner.... it doesnt.
and tried it for size over a suitable (ie spare) cortina tank
This is the granada pump and swirl pot(the plastic box), and the cortina's pickup pipe. I checked both gauge senders with a multimeter, they arn't even nearly in the same range, so the cortina one will have to go back in somehow.
cut hole in top of cortina tank, weld swirl pot (it was spotwelded into the granada, I drilled it out) in place.
trimmed the mounting plate to match the new hole
shortened the pump assembly slightly (about 5mm) so it fits properly..
and weld it up.
Inside shot. (camera poked into the old pickup hole, torchlight down the fillerneck, lol..
Still to do.... plate up the hole from the original pickup, and swap the senders over. Then I can test for leaks (I use compressed air and washing up liquid... pressurise the tank slightly, and brush soapy water round the joins. any leaks will be obvious)
IMPORTANT NOTE....BOTH these tanks have been stored empty and vented (no caps) for over a yeaar, I thoroughly cleaned out and dryed the cortina tank before welding on it. Petrol vapour isn't stuff you should mess with
