Hey guys

Im going to boosting my d16y5 at about 12-15 psi, havent decided yet


im ordering vitara pistons, normal sized

now, i know i could use LS rods or whatever, but i would rather go Eagle rods


I have heard from people and read that you need to knotch the block?

I also have heard that the newer eagle rods dont require block knotching?


can anyone confirm for me? this is a stock d16y5 motor.


thanks

 

the eagles we've used required notching... no big deal though.. nuthin a dremel and grinding bit cant do hehe

HTH

 

really?

so no matter what, block needs to be knotched?

how much

 

all dseries need to ne notched for eagles

 

great.

thanks

 

The block and main girdle need to be notched. A dremel may work but a die grinder would be much easier.

p.s. this is the all motor fourm.

 

I know on the a6 the main girdle does not have to be notched. I believe on the y8 and y5 that it will slightly have to be notched. Go to the Endyn website and look in the archive section, it has some good pics of what is necessary for the process of notching the bottom of each cylinder. You really aren't going to want to use a dremel, you will need a die-grinder with a long extension to do it.

 

The oem rods are press fit and the eagle rods are not.

LS rods have to be rebushed at the small end for the d series 19mm wristpin and the big end needs shaved to fit the journal of the d16 crank.

block needs notched for just about any aftermarket rod, Also for the ls rods.

Vitara pistons are floating pin, no machining required.


Why is this in the allmotor forum anyway?

Since when? Every Eagle Ive seen is floating pin.

This setup has been done 100 times successfully with no machining.

 

I just thought the vitara pistons were like the oem piston and came stock without the clips to hold the wristpin

I Have my terminology wrong, you are right the eagle is floating.

So i take it the vitara piston can be used with floating pins and press fit pins?

Oem piston and rods have the pin pressed into the rod and it floats in the piston. So yes, vitara's will work in oem pistons because the pin is held in place by the rod. Eagle rods are floating pin, like used on all aftermarket forged pistons.

Edit: You changed your post before I could respond.

Why the hell do they call the pin a "floating pin" when it is stationary?? thats just dumb. they should call it a "fixed pin".

The pin doesnt float. The rod floats on the pin.

 

its in all motor because i didnt know where else to put it


i have also heard about the vitara's using floating pins on the rods, but i dont understand it, until i read these posts


so the block would have to be knotched no matter what rod is used other than a d-series rod.

The pin is not stationary, what gives you that idea. Its called a "floating pin" because its not fixed in either the rod or piston. The only restriction it has is the circlips in the piston that are only there to keep the pin from hitting the cylinder, it has the freedom to spin in the rod and the piston.

 

Oh I thought the clips put tention on the wristpin. Makes sence now. I have had eagle rods and arias pistons for 3 years and havnt installed them yet.

 

you might want to wait for fjt's new I-Beam rods that require little to no notching.

Those will definitely hold for the amt. of boost you're planning to take. Next time try the tech or FI forum...

 

My girdle is notched on my a6, and I bet it didnt need to be.
