Add a piston ring to up compresion 4 ring I6 200

[roghax85]

Hello

I like to know if anybody did it.

I want to add a four piston ring to up the compresion level.

ford 200 1966

Thanks.

Not that I've heard,
I think you'd get more gain per dollar gettin a set of total seal rings for them rather than having custom pistons made.

But a pro might jump on and say otherwise.

The really old Ford Flathead engines use to have 4 ring pistons this practice was dropped with the more modern OHV engines. Adding rings doesn't add any compression but it dose add friction and will reduce power somewhat too. The newer engines still use 3 ring pistons but now are using even thinner rings to reduce friction.

 

[roghax85]

so, this is not a possibility?

I am for looking flat top pistons or dome piston, but not so expensive to 200cid. but I can´t find it.

Thanks

It might be possible get custom pistons made with 4 rings but depends if they have or will make special blanks with four ring lands. I doubt it would not be expensive though. You can find flat top pistons here that would raise the compression ratio and I know they also made hi dome pistons back in the day when the fuel was higher octane. How much compression do you want and are you planing to run racing type fuel?

A better solution is to use Total Seal zero gap rings. I put them on the crossflow and they cut blowby to nearly nothing. Manifold vacuum goes up as does effective compression.

The street set uses a moly filled iron top ring and a zero gap second ring.

Thanks man, where can get this rings?

anybody know if this can be use:

or why not?

thanks

Bore size is too big, these could work depending on your block condition (bore size you now have).

Thanks man

exacly why dont work to me the 2.3 ford pistons?

and if I but the kit that you tell me, what more need?
-thanks

The 2.3L Ford L4 SOHC engine has a stock bore size of 3.780 that’s a .100 oversize of the stock 200 L6

The 200 Ford L6 has a stock bore of 3.680 usually the max overbore for them is about .040 to .060 unless you get the cylinders walls sonic checked it would be risky to bore it .100 over

The Ford 2.3L and 2.5L L4 HSC motors both have stock bore size of 3.680 same as a 200 and 250 L6. The 2.3 L HSC piston will fit in the 200 engine, the 2.3 or 2.5 L HSC piston also fits into the 250 blocks.

Is your engine apart now and do you know what bore your block is IE Std. .020, .030 etc.? To be able to use them in your 200 you would need to buy two sets or find 2 extra pistons, bore, and hone the block out to fit.

8) as to where to get zero gap second rings, perfect circle sells them.

Let me try to understan:

I just need to know the exacly status bore size on my engine and 2 set of pistons with rings, like it:

Example, if my engine is it standard:
kit1 and Kit 2

apart of the kits and pistons rings what more need?

My piston rod / piston pin actual work to me, or I need to replace too?

Thanks and sorry. I am new on it.

Let me try to understan:

1. I just need to know the exacly status bore size on my engine and 2 set of pistons with rings, like it:

Example, if my engine is it standard:
kit1 and Kit 2

1. Correct

2. apart of the kits and pistons rings what more need?

2. Block cleaned bored oversize so the cylinders are straight and true. Install new cam bearings, new oil pump, new cam and lifters, timing gears, gaskets and seals. To hang or install onto your rebuilt connecting Rods and if you plan to race it use ARP rod bolts, polish, and shot peen the rods. Also a polish your crank journals if it still mic's in spec, or have it reground to next under size, a with new set of Rod and Main bearings, balance the rotating assembly too.

3. My piston rod / piston pin actual work to me, or I need to replace too?

3. Pins that come with new pistons should work as is.

Basic Engine Dimensions (inches)
Ford 200 Bore 3.680
Stroke 3.126
Bore Spacing 4.08
Con Rod Length 4.715
Deck Height 7.808
Piston top to Deck 0.019
Piston Pin Diameter .9122
Pin Compression Height 1.511
Piston pin offset .060.

2.3L HSC Bore 3.680
Stroke 3.300
Bore Spacing 4.08
Piston Pin Diameter .9122
Pin Compression Height 1.520
Piston pin offset .090
Bonus the pistons are about 32 grams lighter weight than a stock 200 piston too

The 2.3L HSC was based off the 200 six block so they could use the same machining equipment and mod the casting molds cutting two cylinders off the back of block. The pistons are a direct swap they are flat tops (stock 200 have dish) with a slightlyholier pin location with these two changes to the piston design when they are used in a 200 they will raise the compression ratio about 1/2 a point. They are available in Std. And over sizes up to .080 over.

The 2.3 HSC pistons will work (1.50" compression height), but the 2.5 pitons have a 1.556 compression distance and are a bit too tall for a 200. They will work in a 250 to help bring up compression a bit.

X2 have been thinking of piston combo's to try in my 250 to try and tighten up the quench and raise compression ratio.

 

[MustangSix]

That's still not tall enough to do anything for the quench, but it will help fill up that big depression a little. :roll:

Hello all

I did it. remove a piston and I am attaching picturs.

Cylinder

Where I can get new cylinder sleeves?

The piston to 0.30

Anothe question: anybody bouhgt here: http://www.enginepartsstore.com

And I like to know exacly if anybody used before piston of Ford 2.3L HSC to 0.20, but flat top.

Thanks
