Alternative stroker short block combinations

[auditude]

I have a U.S. spec Eurovan motor with the 95.5mm stroke and no oil squirters. I thought the best way to use it would be to replace the rods and pistons to build a 2.5 liter 20vt stroker motor. However there were some questions asked on here that got me thinking about other possible uses. What do you guys think of the ideas below?

The stroker 20vt has been done with the 95.5mm crank using either the standard height or taller height engine blocks. Other stroker cranks are also used in the standard block, such as 94.5mm(I think?).

So I think it was Josh that was asking about which part of the short block to use, the crank or the block. At first I thought it was a question with an obvious answer: Both, so you increase the displacement while keeping piston speeds lower than with the shorter block.

But then I started thinking. Perhaps using the standard crank with the taller block, in 2.22l configuration, would slow piston speeds down enough that the maximum rpm can be increased. This would make sense since most big turbos only start making power at the top end of the rpm range. The graphs often look like they would just keep on making more and more power, but because they approach redline they have to shift.

So what I was wondering is if the combination of the taller block, custom pistons and custom rods that were longer than stock, and the standard crank, would result in more power potential due to being able to rev the car higher than with the standard rod length. Is the rpm limitation at the bottom end, or in the valvetrain? I know people talk about piston speeds, not so much about valve float. I imagine some specialized headwork such as solid lifters might be necessary?

A side benefit is that the crank could be used to build an opposite-spec motor with the increased stroke and standard block.

What do you guys, such as Marco but others too, think about this idea?

Thanks,

Ken

the 95,5 will fit in any audiblock....yea you may use the other crank from 2,2 or 2,3liter(86,4) in the eurovan block (deckheigth 236mm),but you have to use even longer conrods than the 155mm or like me 158mm,or even some 4syl audi 2liter(159mm)...you may use 165mm and 86,4 cranck and custom pistons..... and you will have a really HIGH rev engine,but you will increase more rev (over 8000)and hp if you have drysump oilsystem.the oil will steal about 15% of the top hp.... the S1 engine have max rev at 9500.....with the short block(220mm) and 85mm stroke........
