as of now le5 sleeves are available they are undersized and made of ductile iron and chrome moly

will be installing a set in a zzp block this weekend

 

Get your car running already man

 

Just a noob questioon i guess, why undersized?

 

waiting on the machine work to be finished

so you can bore and hone to get the proper piston to cylinder wall clearances

 

Nice!

 

alright then, thats not what i was thinking. so its barley undersized. what about the 98MM Sleaves you had talked about in the hybrid thread?

 

putting a le5 sleeve in a zzp girdled block

 

those are a wet sleeve like a darton (I cant install those)and with a le5 crank that gives you a 2.7 litre

 

Right, I remember you posting that, and I thought it would be cool. At links on wet sleeves? I just don't know much about cyl sleeves, but would like to learn!

 

I don't have any links as they are a custom setup made to order

 

ahh ok.

 

care to share the price?

 

Holy hell, what's up Noor!

 

Is that a gen2 girdled block?

 

just some summer fun

 

Any point having these installed in a gen2 girdled block?

 

if you are making a stronger bottom end, no point to spend the $$$$ on a gen 2, gen 3 is superior in everyway

 

don't mind the gen2 portion of the comment. i think what he's saying is if it's already got the guard, and that's proven itself 700+whp many times. along with ryans 900. why do the sleeves?

It's a valid question. but i think when i do my next 2.1 i'll still do these sleeves. for the cost it's more than worth it for the extra piece of mind.

 

And I already have the gen2 zzp girdled short block, bought 3 months before they discontinued it. I would do the sleeves with new pistons, all zzp had at the time was 8.8cr and they suck fuel like greedy pigs. I'd go back to 10.4 cr and have the piston to bore clearance custom honed ...which I doubt zzp does with the stock sleeves.

Just a thought for next season.

 

Zzp never gets there bores perfictly round. They buy pistons 0.002 over size to get it close. Its kinda a halfass way to do it if u ask me.

 

exactly, and because this is my first and last hot rod I will pay the price and finish it to proper machined tolerances.

Barring a crash I plan on having this as a toy for years to come.

 

Ya i got stuck with a block i bought from them with worn out cylinders. 1500$ down the drain

 

This was my block. It is a Gen 2 LE5 and I bought it in January of last year from ZZP, before they introduced the Gen 3. The cylinders were fine and round, but after about 3000 miles the compression test showed low numbers. After taking it apart, it was discovered that the piston-to-cylinder wall clearance had become excessively worn, likely due to my improper honing of the cylinders (since I am an amateur and not a pro shop). It was decided to replace the sleeves instead of pistons as the sleeves were far cheaper.

On a good note, the aftermarket sleeves from mrbelvedere, while being significantly stronger, are actually cheaper than GM OEM replacement sleeves.

Now I have an even stronger block, and peace of mind.

 

yup

to get the clearances set up properly

yes there is a point not every one has 2k laying around for a block

even with the block guard/girdle the stock sleeve will still flex from pressure these wont and you will also have better ring control/sealing from the loss of flex

 

And from my understanding MRB's sleeves have a slightly tighter fit alowing the sleeve and block to work together to support each other.
