http://www.zatzy.com/showthread.php?...0&page=6&pp=20 HOW TO DO THE BLOCK FOR THE 95,5 MM CRANC AND 158X23 conrods

[newsh]

So, if I was going for a "tall" block using a diesel block and crank from a van and bored to give 2.6L and running a 3071 on RS2 style mani and 3" turboback, what comp ratio would be best, bearing in mind I want good low and midrange.
I'm also tempted to use 3B cams for the instant pickup.

And where can I study the mods I need to do to the block?
I guess Pisobiker's thread would be a good start?

Just the bottom end with the short block by the looks of it

Yes, but does it mean "just the bottom end" or does it mean "short" as opposed to "tall"

I guess I could always email them, there's no data on block height, crank throw or rod length that I can find.

[newsh]

On the Eurospec site when they use the term "short block" normally that means an engine without the head and ancilliaries, or does it mean as in the height of the block to differenciate it from the taller diesel block?

[newsh]

Looks like I've got a lot of reading to do, I want an engine I can put a lot of miles on thats for sure..

[caterpillar]

you may use the 2,4 diesel eurovan block too,( 78hp) the diff are only you have to rebore the block from 79,5 to 81,0 or bigger....

i agree, he needs to find what he wants and go for that route. But to my remembrence, is there not a company in usa or something, can not find the link. That sells new both long and short block 5cyl engines
They werent that expencive either i think

Eurospec, if you have a look at the links I posted 1st with the Red S6 the engine came from there. http://www.eurospecsport.com/stroker.htm

They only do short ones at the moment according to motorgeek posts how true this is I don't know

Yes, tall block is the key here. Tall block requires long rod. 144mm is not considered as such.

144mm rod and 95.5 stroke crank are not compatible. Most certainly not for 1000hp, sad but true.

No doubt the tall block is better when it comes to extremly high hp levels, both rod/stroke ratio and strenght of block itself!

But I am not sure if I fully agree that 144mm rod and 95.5 stroke are NOT compatible. I know more than one engine with 600-800hp levels that have run very well for a long time with such setup.

Jonus also used short block with 95,5 cranck in the 2004 season. With best time 1/4mile 10.07 and 238km/t. That engine was never dynoed but my guess is that it had very close to 1000hp.
That said: it was not a daily driver, but was driven in a lot of track and dragracing events.

In my opinion the big question when builiding high level hp engine is: Do you want an engine that runs 30000km a year for let say 5-6years without any problems?? Or a trackday racer with 5-10 000km a year with frequent service intervals??

[Jamo]

this is the exact same engine that jonus drove, with 800+hp and no probs. So i would say thats prof. And some one asked if there was a stroker for sale, and i replyed i have one, no need to say bad stuff about engines that one, has not seen or letalone tried and tested.

There is a stroker with the short pistons that blew up on the forum from Aronmatic.

We are not discusing your engine or giving it a bad name merely giving Newsh all angles and being objective about what stroker is best for his goals.

friend of

mine in norway is running this with 700hp and no probs so. They deffo work for more then enough hp. He uses this dayli.

[Jamo]

Oh come on Jamo, you know you want to sell it to me

I need to start doing the research but to start with I need to chose between the diesel and crank or the stock block with crank and rebore and what rods/pistons etc..

Iceland man are you selling? Or just bragging??

Give me a shout it you want, your block choice is going to be key and how much you want to spend.

If you want to use your standard 220mm block I would advise a 92.8mm crank from 034 and go the way of this and you keep your rev range http://www.motorgeek.com/phpBB2/viewtopic.php?t=4966

I don't like the short piston compression height that is required to run the 95.5 in the 220mm block.

[newsh]

I'm leaning towards tall block but not entirely sure of the pros and cons, I guess there's more mods and fiddling about with the tall block..

I want big torque and midrange.
