Is anyone using this? Are they actually worth it? Is the install really that much of a hassle as they say?
 
personally i think they do nothing,

it is not the top of the cylinder wall thats at risk as the rod is at its staightist angle, its when the pistons is bout a quater the way up the cylinder the rod is at its steepest angle putting strain on cylinder walls..ie not the top

a friend of mine mate works in golden eagle and was told they on;ly make them cause people buy them and think they do something...

it is also said that they can cause hot spots because cooling is affected..
(but that's hearsay)

im building a b20 and am not using one
 
Thanks for the info mate. :nice: I also heard that they're a bitch to install too. But would you need anything like that for a 1800cc stroked b16b with stage 4 cams, that revs to 9200-9500? Just to be on the safe side i mean.

yea they need to be pressed in while your block is getting machined...

tbh mate darton liners or sleeving is the only way to go if your worried about the integrity of your cylinder walls
 
The engine is in good nick. It's been very well maintained. I was speaking in terms of extra safety measures.

A fool and his money are easily parted, which is probably the reason 80% of the aftermarket industry exists!
 
I hear that the cylinders bulge out toward the center and not at the top.
So a block guard would not help for this issue.

But I thought that a block guard is/was to keep the cylinders from "walking" when under high pressures like one would see on a turbo/NOS set-up.
 
i thought it would be useful to have a block guard of your planning on a high boost/ nos setup or if your going to be revin very high like spoons engine.
 
id personally sleeve a block rather then use a block guard, depending on the application
 
Sleeving is very expensive though, a better solution on a budget would be to have the block posted, this way the liners get the re-enforcement it needs, where it needs it as opposed to the block guard method.
