How do I fit a pinto EFI in my Indy?
I want to fit a 2.0i pinto in my Indy and was wondering exactly what i need to modify to make it fit? I've seen something about getting the
plenum(?) modified, where can i get this done and how much will it cost? Do i have to do anything else?
Also, is the rest of the block the same as the standard 2.0, just with injectors rather than carbs?
Any help appreciated

Not sure how high the Pinto sits in the Indy, but in the Avon, the sump needs chopping and there is no chance for the plenum chamber so 40's or
45's it is.
As far as I know the engine is the same as a carb 2ltr apart from the head which is much better with bigger ports and better flow (don't quote
me on that).

Hi
I used this engine in my Robin Hood and it is probably the best Pinto you can use. The block is the same as the older 2.0 pintos. The head is slightly
different being ready to use unleaded fuel and also having slightly bigger inlet ports (to accept the injectors) so this is the head of choice if you
want to dump the injection system and replace it with some 40/45s
The down points are that if you want to increase the power output by replacing the cam you will find that the ECU cant really compensate. AS far as i
know it’s also not possible to get the ECU remapped.
The lowering of the plenum is something you can do yourself if you don’t want it sticking through your bonnet. Have a look on my site
www.daxrush.organd you will find some pics of a moded unit and a link to the Robin Hood site modifications page.
Hope that helps

Thanks for the help guys.
How much taller is the head? I've got a modified sump but I don't think there will be a lot of clearance at the top with a standard
engine, let alone one with a bigger head. i guess if its not too much taller I could whittle the mounts down a bit and squeeze it all in!

Pete,
Try this link for some interesting Pinto info:
http://www.pumaracing.co.uk/pinto.htm
apparently the injection '205' blocks are (internally) not quite the same as the carb ones- the block walls are thicker for a start! 
If you want to stick with the injection then as you rightly said you need to get the plenum chamber chopped. Have a look at CairB's photo
archive as he did it himself. MK might do it for you I guess but don't quote me on that.
If you fit side-draft carbs 40's/45's then that get's over the above problem but you'll have to sort out dizzy, coil,
amplifier and a fuel pump.
With either system you'll probably need to get the oil filler cap moved/lowered.
HTH,
James

Thanks James, I read that article myself for some info. The way I read it was that the 205 block is the same for carb and injection engines and that
the only difference is in the head - the injection having larger ports and better air flow. Maybe I read it wrong.
Either way I'm thinking of sticking to the injection in standard tune apart from the obvious lowering of the plenum. That way I don't need
to mess around with the engine too much - I've never done much work on an engine before so I want to learn some more before I start messing
around too much!
Do you know whether the injection head is bigger than the carb head or is it just machined differently? i just need to make sure it fits under my
bonnet before i go and buy one you see!

Pete,
I re-read what I wrote and realise it was slightly mis-leading- sorry!
Yes, as far as I know all '205's are the same- what I meant was they were different from non-205 Pintos!
Should'a just kept my trap shut!
Could someone confirm for me: all EFI engines are the '205' type? Also, no carb' were 205?
Cheers,
James

James, the 205 block is for both the carb and injection engines, meaning that the only difference between the two (as i understand it) is that the
injection has a better head, and obviously the fuel systems are different.
As far as i know the injection was only available in the 2.0 version and so i assume that all injection pintos use the 205 block. Im not 100% sure
though so don't quote me on that...

Another question...
Looking at some pictures of lower plenum EFIs i have noticed that they have 4 large holes facing away from the engine that correspond to the position
of each cylinder.
What are these holes for? Are they air intakes? If so, should they be left uncovered or do they require an air filter fitting over them?

Those holes are where the pipes to the inlet on the head originated, before they were chopped off. They therefor need blanking off. The head height
thing im not so sure on, but i would put money on the height being the same. You can remove the Siera rocker cover breather/oil filler cap which is
quite high for one from a granada 2.0efi and you will gain a couple of inches.

You can also blank off the current filler cap and replace it with a tube at the back of the tappet cover- see Bob's archive for pictures.
I did mine by cutting out the hole from a VW Golf tappet cover. Then cut out the hole on the Sierra one and gas welded the wider Golf one in place.
The flat Golf filler cap then fits. Total cost: zero as the Golf had been abandoned near me. Also means you can use splash guard etc. from Sierra.
HTH,
James

For the oil filler cap i've heard you can just cut the existing one down so it sits lower. under the main top piece there are a few thin plastic
slats that stop the cap sitting all the way down. if you just chop those off with a stanley knife the cap sits about 10mm lower. i'll have to
wait until i put the engine in the car to see if this is low enough but i've seen pictures of other cars that have used this method and
they've been ok.
