I’m building my daily B18b1 for boost. Going for a full rebuild. Because it’s a daily and I intend to put a lot of mileage on it, I wanna raise the rod ratio even if it’s only slightly so I was thinking about longer forged eagle rods. It’s either this or darton sleeves to handle the lateral forces better. I just wanna know if anyone has any experience with longer forged rods on boost? Want to make sure I won’t be compromising motor integrity drastically

Thanks in advance!

 

Longer rods make the engine last longer doesnt compromise its lifespan.
Youll need custom higher pin pistons..
And yes, its completly not necessary.
Go darton.

 

As stated don't bother getting custom longer rods and adjusted pistons to increase the R/S ratio. Do a CSS block or full-sleeve like Darton and any reputable rod/piston combo.
B18B's do wear the side of the bore (thrust loading) - its a given fact, but not to the point where its failure prone.

Even though the B18B has a poor R/S on paper - the engines are amazingly strong and rev happy when using the right parts.

 

I have already found eagle rods that are slightly longer than stock, isn’t there a piston made for that application?

 

I’m not scared of the engine failing suddenly, but more so the wear and so the life span of the motor when making high torque for often than not. And the rods wouldn’t have to be custom, golden eagle makes them off the shelf. The sleeves are definitely in those top options. What I want to know is if there is anybody who has experience running longer rods in an ls

 

I have really long rods in my B19C5/1 engine. As stated above by Balor Gr and extremeracer, longer rods aren't really necessary and although scientifically increasing the rod-stroke ratio will reduce side loading... there are other improvements to fortify the block that will be money better spent. Sleeving would be one. Now, you have mentioned that you have Eagle rods that are "slightly" longer than the stock rod... does this mean that you have a set of the 5.404" LS rods or something longer ?

 

I do not have the long rods yet but I have found a set. They are a little longer than 5.4 but for now I have in my possession standard length forged rods. That’s why I’m trying to get all the research and info I can. The thing is that I’m more so worried about the piston rings and that wearing down. I’ve considered sleeves as well as certain piston pins with a certain offset, but when it comes down to it I will be running this engine pretty rough as well as putting milage on it
