I have a GTS engine block for sale. These are very hard to find. This one has been bored to 104.0mm Makes a 6.0L motor when assembled with the stock GTS crankshaft.

Asking $2300

Green hue is the sealant placed on the cylinder walls to keep them fresh until the engine is built and run.

What kind of pistons would go with this setup?

Rob Edwards

I'd stuff it with 968 pistons.

ROG100

That is 928 **** right there!

To what exact spec is it bored?

James Bailey

This the block which went missing during the Phil Threshe debacle ??

Jim Morton

Suspect it is... Hans should not have the COA for the GTS this would have come from.

If so, hopefully Carl will work with Hans to get the correct block back with the car.

Pistons are designed depending ion the application. Boosted, NA, compression ratios, piston ring size, coatings and venting (if any). I can help you order the right piston for your intended use. Our pistons are made by Arias to our specifications.

I would recommend this block be used for NA only in its current condition because of the wall thickness. If you wish to run it boosted, then I would sleeve it with steel liners for you.

what is the wall thickness after it has been machined ?

Carl Fausett

I'll measure and post it.

Can you make it a bored and stroked engine? Like a 7.0L or something?

Carl Fausett

Yes, I can and I have.

If you use the stock GTS crank (that has a 85.9mm stroke), this block with a 104.0mm bore will make a 5327 cc (5.8L) engine.

If I install our stroker crank with a 95.25mm stroke, it will make a 6472 cc (6.5L) engine.

To go larger, I would use a different block (no need to cut up a GTS block) and install wet sleeves.
I have built 7.0L 928 engines this way.

Carl - Can you describe the differences between the wet and dry sleeves? From the photos it looks like the "wet" sleeves have superior cooling? Does a wet sleeve using this block significantly reduce rigidity? To what effect?

Thanks,

Carl Fausett

Yes, I can. I will be out of the office until Wednesday, I will try to answer this then. Until then, there are several here who should be able to answer that question also.

No hurry. I'm still trying to decide what to do with a spare 5.0L block from an '85. It's isn't going anywhere soon.
