I want to do something about my -88 Pinto EFI engine (205 block) to get some more power out of it.
And I´m thinking about in the first step just do the cylinder head with modified ports, another cam and maybe bigger valves.

What cam can you recommend for me. And where to buy it.

Even read a post where someone suggested a cosworth head.
Is that possible without modifications?

Or do you know anyone that´s gonna sell a modified head that suit my fuelinjected Pinto.

I´m going to Stoneleigh this year and it´s not that hard to take a cylinder head as handluggage on the plane.
My friend bought 2 carbon seats last year and took on the plane home.

I,d suggest you first task is to get a book on tuning, Dave Vizard did an excellent one on Pinto's.

I followed this with a carbed engine, 60 thou off the head, larger inlet valves and porting increased the power by 30% with standard cam (its actually quite a good profile).

Regards Mark

Im no pinto expert but am learning fast. I read Des Hammills book many times and thoroughly enjoyed it. Ive since ported my head and fitted FR32 cam onto std bottom end. Feels very strong on the road. unfortunately no rolling road figures yet. Its also got full stainless 4 branch exhaust and 38DGAS carb). Fr32 is not silly high lift (fast road) and ticks over very nicely, power comes in low down.
Mookaloid will no doubt be along soon and will give you some sound advice. He is currently assisting me to great effect. I guess one of your problems will be being restricted with injection system (i assume you are running std injection to keep yourself right with the law??). What exhaust system you got?

Do you have any books? I only have Des's book but would love to get hold of Sir Davids as well. Email me if you dont have Des Hammil book.

FR 32 cam (or piper 285 which I think is very similar) are both very good, bags of low down torque and better top end than the std cam.

For once a cam swap that has no downside.

Used to use one on the sierra road rally car to very good effect in combination with a 38 dgas carb, when set up it was spot on!

If you want to keep the standard ford fuel injection both Kent (FR34) and Piper(can't remember the number) make a cam designed to work well with it. Fit a vernier pulley. You can do a lot with some simple head mods without fitting larger valves. A skim to raise CR, three angle valve seats and a little blending of the ports.

Hi Jonte,

The secret to getting power out of the Pinto is to improve the breathing through the cylinder head.

The things holding your motor back at the moment are the standard inlet manifold, the ports, and the cam. You have a good exhaust system already

you don't need bigger valves for a mild tune but if you use one of the cams mentioned above, do some porting as in one of the books mentioned and put some throttle bodies on you will see some big improvements - I don't know what ignition you are using but this might need some attention too.

Feel free to ask me any questions you may have

Cheers

Mark

I am not familiar with the model you mention but for the SOHC 2000cc engine you can change the cam timing by redrilling the dowel hole in the top timing belt pulley. Usually 2 deg will not be felt in the seat of the pants but is seen in timed runs like drag racing. Keep the change to under 6 deg or valve interference may occure.

Thx for all replies.

For the moment I´m gonna use standard Ford ECU, but I´m gonna change to Megasquirt this year.
And the injection stays there due to some laws here in sweden when I SVA´d the car.

Also I recommend you get a Burtons catalogue (free) by post. It's also an interesting read plus they sell everything you might want.

Where is it possible to find another inlet manifold that fits under the hood of MK Indy?


So where do I find the FR32 or FR34 cams at the best price?

I´ll stick to the injection on my engine.

Found in Burtons catalouge that FR34 is for the FI pinto.

cams come up on ebay quite often

When Mookaloid says throttle bodies are the way forward he doesn't mean carbs....throttle bodies are still injection except they are individual....rather than having a plenum (big tank thing and maybe one throttle body controling the engine you have four seperate ones...this means that you can get rid of the old pinto inlet manifold and fit a custom one so each cylinder in effect will have its own pipe leading to its own injector and then the atmosphere....breathing will be much better and cos its injection you still get all the benefits of well metered fueling etc etc....also should be OK with any laws etc as technicaly your not changing anything eg from injection to carbs where emissions are the problem....throttle bodies work very well with any engine but especially pinto's where they can breath free.....If any of that is wrong I'm sure someone will correct me....Oli.

ahhh....ok
You learn something new everyday

Can someone point me where to find info about that. Thats completly new thing for me.
