I have a MK1 escort with obligatory 2.0 pinto I have had the car for 9 1/2 year now and its well past its best. I am planning on beginning my restoration on it just after Xmas and I have been collecting bits for the last year for it.
I have a ported big valve head to go on. I have a pair of sidedrafts to go on but I have changed my mind and am now planning to go for injection instead. At the minute I am considering getting an injection sierra engine (205 block) using the bottom end of that with my new head I am also toying with the idea of using the inlet plenum from the injection pinto so I would just have a single throttle body. Has anybody got any idea how much of a restriction if any this would give over a pair of 40mm throttle bodies.
The reason for going down this route is the obviously cost. I should be able to use most of the sierras sensors including the sierra throttle pot, not sure of the injectors capacity I know they can be used for 125bhp but I am planning on around 150-160bhp so will probably have to change them. Admittedly not a lot compared to a modern 2.0 but I really want to keep a pinto in this and if I loose a bit of weight from the rest of the car I should be getting closer to 180+bhp/ton.
Bit of a long winded thread for a simple question but any ideas or criticism greatly appreciated

Costwise, it may be cheaper to look at bike TBs...?

id just use the block and put carbs on it! as we did with my cousins mk2 1300 auto sleeper a few years ago after oil pressure probs with the dry sumped rs2000 block! went rather well considering we borrowed the engine from his 2.0i sierra e-state parts chaser.. u aint got any mk2 scort ghia square headlamps laid around going spare have you? know a fella who needs a set...

The only problem I can forsee is the engine management. The Ford setups include stuff like road speed and whether the vehicle is 2-up or 4-up (God knows how it works that out!), so unless you've got the correct sensors, it may not run right. Not sure if the injection 'box has a speed sender on it or not, but final drive ratio could come into it. If it's any help, the injection Sierra's have a 3.92:1 diff ratio. I've taken this info from a Haynes workshop manual, so I'm making no claims as to it's accuracy..............

You could use bike TBs. I got some for the Imp for about £40 delivered via fleabay. If you shop around patiently on there, you can get a bargain. A plenum system could be used. Some 2.0i Sierras had injected Pinto motors. Get the bits off one of them and bung a larger throttle body at it for less flow restriction. I'm

Not in my Experience That explains it then there was an article in either PPC or RCM about doing this swap, Injected motor replacing carbed Pinto Bolt in/out with 3 wire connections if I remember correctly ?? certainly not much more complicated ?? The biggest issue you`ll have is running into the limitations of the standard ford system pretty quickly, it wont like anything more than a mild road cam... I think you will struggle to get 150hp on the standard setup, wheras a Twinchoke Weber will do this easily If you are running standalone management then thats different, but if that was the case you may as well cut down the manifold and TB it using Bike throttles HTH Dom

I intended on either an emerald or megasquirt with the sierra temp sensor and throttle pot and a crank sensor fitted and the dizzy blanked off. don't know why but I quite fancy the idea of using the standard plenum just wondering if it would create a restriction. I think the surface area of the sierra throttle body is over 50% the size of 4 40mm`s throttle bodies. If I was using carbs then 40`s or 45`s would have chokes about 36mm so its even less of a difference. Plus if I wanted to create a forced induction system at a later date I could also carry on using this.

Thats fair enough then, the thing you will lose out on is throttle response, as a single throttle on the end of a plenum will never match individual butterflies close to the head for response. but it will work ok, and like you say, makes it simple for forced induction later

topghia and i were pondering installing 3i bosch k-jetronic injection to his mk2 xr2 to release an extra 15 bhp, and found that we only needed to add 3 more wires to the loom to get it sorted, not sure what managment the 2.0i sierra's are tho... as i think there were a few used, and i think the cvh had different managment to the pinto

But that is really only of use as standard so I would have no real gain over the DGAV I have fitted now, possibly slightly better fuel consumption but considering I drive it everywhere at full throttle I don't think thats much of an issue ;D
