Pinto Yo - Help

[BorniteIdentity]

Hi

 

As you may have read, Alf892 and I are involved in a pinto refurb for the bASe Sierra.

 

He came up with the genius plan of getting another head from a guy he knows and refurbishing THAT - plonking it on and giving the dude my old one plus some lager beer.

 

Thing is, like, we suspect the new head is a 2.0.

 

The bASe is a purebred 1.6.

 

Will the very axis that earth spins on be destroyed if we mate a 2.0 head with a 1.6 lump?

 

If not, what are the likely behaviours of this bastard child?

 

TiA.

I'd check the bore & valve sizes. If the bores are larger on the 2.0 (which I'd expect) with larger valves they might not open as the block would be in the way on the 1.6.

 

My illogical thoughts would be keep the original head because it's the right one for the car even if the other fits.

I agree. It was more about ease, as I don’t really want the thing immobile.

I think they put the 1.6 head on the low compression 2.0, chances are it will make no difference.

 

Edit, if you want to borrow one to swap I have a 2.0 head in Chesterfield with a decent cam and followers but it's burned a valve.

Why not measure the capacity of both? as long as they are similar then it won’t make a massive difference (I am sure you probably know how to do this but if not give me a shout and I will go through it). My guess is that it will either be ok as is or need a light skim to just up the compression ratio back to what it should be.

[garbaldy]

Many moons ago I stuck a 1.6 head on a 2 litre for much improved compression but it didn't last long at all.

 

Come to think of it I'm not sure wether that was down to my teenage lead feet and thrash happy care free nature or not.

[Tamworthbay]

I may also have a spare 1.8 head that you can have and then keep your own and do that at your leisure. If it’s any use give me a shout and I will have a dig in my spares pile.

Are you not going to lose a fair bit of compression as the combustion chambers will be bigger ?

[cort16]

From another ford website

 

2.0 on a 1600 is another waist of time cos the comp ratio will be far to low and you'll need to skim the buggery out of the head to get it back up which will then meen you need a vernia to get the cam timming right.

I'm not sure about that being correct as if it was everybody would want to start with putting a 1.6 head on a 2.0 rather than skimming loads off a 2.0 one.

[cort16]

I Believe there are loads of other complication to putting a 1.6 on a 2.0

I know I'm funny with engine changes so I'd go with what Hooli says it's the original one and is right for the car any others are wrong* but more than that they mean loads of messing an potential for who knows what in the future.

[fordperv]

The compression bowl is bigger on a 2.0 head so will lower the compression, also there is slight valve size difference

 

I would definately freshen the original head up and put that back on

I fitted a 2.0 head on a 1.6 pinto many moons ago. The cam timing was always half a tooth out & it was always lumpy at idle.

[The Reverend Bluejeans]

It will be shit. The 2.0 ports were too big for the 2.0 and hopeless on a 1600. Get the right head and do it rite.

Useless. The 1800 and 1600 Emax have Siamesed bores unlike the 1600/2000.

[New POD]

Or a turbo decompression spacer/ gasket?

That would further make the compression ratio lower

[M'coli]

As many others have said, the 2.0 head is different enough from the 1.6 head to make it a bad move (although the valve head diameter is slightly greater, I believe that the valves themselves are actually shorter by a couple of mm on the 2.0 head).

Keep the original head on it if you can.

[Des]

The 2.0 head is actually a quite decent upgrade when executed properly, with a 2.0 block.

[danthecapriman]

What they all said!^

 

Personally, I’d stick with your 1600 head. Remove it from the car and simply rebuild that and while your at it send it off to get hardened valve seats machined in for unleaded. It’s all dead easy and doesn’t take long if you’ve got all the bits you need ready to go. I stripped mine off the Capri and did all the work and had it back on the car running well inside a day. The only hold up was getting the unleaded valve seats done.

Isn’t the Sierra off the road currently anyway? If so then it’s not going to matter about keeping the car mobile.

Yeah I know, I was thinking about bringing the cam timing back, it’s obviously been a long week.

Chuck lot and fit a 1.6 zetec.

Oh dear your gonna get it in the ear now for daring to mention modifying

No I’m being serious, be a lot more economical, reliable smoother unit than the old pinto, I think you could drop one in and make it look fairly factory. Keep rest looking standard and you’ve got something that with regular oil changes should be problem free.

Fit a VW 2.0TDi to your Ferrari Testarossa while you're at it.

I don't get the point. If you want a newer car experience then you wouldn't buy an older base model anyway.

[lisbon_road]

Different camshaft as well.  Fix original head, quick and less hassle as so many have said.

 

I wouldn't say I'm an originality freak but using the original head on this one seems quite nice.
