WANTED: 3 Standard Ferraru 308 81mm Cylinder Liners/Sleeves in Good Condition - Used or New

What happened to these three please?

 

Thank you
I imagiined your machinist would bore yours to be all out to the same, even if it is a second/third oversize is needed
It seems you want to retain no oversizing so opt to buy three new cylinders then hone all to the same new ring set?

Isn't buying 3 new cylinders to retain one less oversize machining a very expensive way when you should just go 2/3 oversizes on what you have now?

Or did I miss this point and you are beyond 3 oversizes and nobody sells sets that grand>size?

 

The 2 most serious shortcomings in the Ferrari 308 2 valve engine was the junk piston/ring package and the too low compression.
You are faced with the opportunity to correct that and you are going out of your way to retain the worst part of the engine.
There are at least 2 brands of off the shelf, oversize, higher compression pistons available and you should be using one of them.

 

A set of Wossner or JE oversize pistons with 10.5 compression with rings is about $1400 US (1300 Euros) . Way below $2500 Euros and you are well on your way to a good engine.

There are no good rings for the Junk OE pistons and alone they will be considerable money not to mention all the other costs involved and you still have a POS engine that makes little power.

Just doesn't seem like much of a decision to me.

 

Where are you getting JE for that cheap? That's way below even our cost. Last 2V set we ordered was $2k.

All other points.. totally agree.

Maybe they are on sale? Saw 12 330 pistons under $2000

Loads of freight forwarding/mailbox companies will accept the JE pistons with a US address then re-ship them to Europe for a reasonable fee. I use them all the time to get ebay purchases that won’t ship international.

 

Wossners are far better pistons. I only mention JE as an example.

Pistons will work fine with all the other stock stuff and are the biggest single improvement that can be made. They respond very well to increases in compression.
I have built many 2 and 4 valve 308/328 engines with bigger higher compression pistons.

 

I run close to 11:1 on US pump gas.

My use of them is primarily with US cams. I put Wossners in a 308 with stock late US cams a crank timed ignition and it dyno'd at 240 as I recall. May have been more. I was not involved in the runs.

Perfect!
Hell of a deal for a stock refresh to improve the bottom end.

 

I had not used them before and was very impressed with them. At the time they were the only off the shelf OS Hi Comp piston.

Have not been a JE fan for a long time since they lost some important people.

Just wish 4 valve pistons were as easy to get.

GTO Engineering supplies them with their new 12 cyl blocks. Built a 250 motor with one of the new blocks.

 

All the QV stuff we do is custom... And yup it's a touch more.

 

To throw another option, we have a piston mfg in Italy that ship direct from there.

 

Yes

 

Have no problem on 91

 

A little while ago you were content to recycle garbage pistons and won out liners for a not inconsiderable expense when people with actual experience suggest a better use of your time, trouble and money. Now you want a promise of good power.

Am I missing something?

Reread the thread. Its all there.
