I FAILED TO SEARCH ARCHIVES, so my questions were answered, but id still like to know past experiences and DIY outcomes.

what do you guys think of this setup
http://www.homemadeturbo.com/t....html
i plan on going FI with my Y8, and this looks like something that i may want to do, since i am on a budget, has anyone tried it?? and if jeff is on here, have you run this block yet? any help on this subject is and would be appreciated.

i know it isnt the same as having a blockguard, but would it be a good cheap alternative?? and is it worth saving the money? why and why not?

This cost $35 + labor, and is uncertain. A block guard costs as little as $50.

 

isnt installing a block gaurd properly a big and expensive job though? one only to be done by a machince shop?

dude, your talking apples and zebras here man. they serve different purposes.

 

Im going to do it on my d16y7 block.. Personally I think that if endyn does it then its probably going to work fine.. They do alot of research on stuff before they use it..

Not really. Both prevent cylinder wall movement/flex.

 

thats what i was thinking..it seems to me that posting would also be so much easier and cheaper than having a block guard installed correctly..

Plus I have heard that block guards limit coolant flow where block posting does not..

 

There are block guards available that allow better coolant flow.

The only thing I don't like about the pinning, is that when cylinder wall flex occurs, the pin is putting a tremendous amount of stress on the point of the cylinder it is touching. Instead of getting lateral cracks you'll get longitudinal cracks.

The block guard distributes said loads about the perimeter of the cylinder wall, in effect simulating the solid deck that most non-Honda engines have.

I am speaking purely as a mechanical engineering student, not as a Honda expert.

 

The pins are made out of the same material as the block so they expand just as the block does..

 

Now you are speaking of apples and oranges. Thermal expansion and mechanically-induced stress are entirely different.

 

Block gaurds have also been knows to warp sleeves into oval shapes . It's really a tough call.
