Alright I been reading everywhere and this was the best info I could find about the l26 rods.

Engine Info/Differences

The L67 and L32 have a 8.5 to 1 compression ratio
The L36 and L26 have a 9.4 to 1 compression ratio

The L67 and L32 have the fuel injector bosses in the heads
The L36 and L26 have the fuel injector bosses in the LIM(lower intake manifold)

The L32 and L26 have an Electronically Controlled Throttle
The L67 and L36 have a Cable Controlled Throttle

The L26 and L36 have one Belt
The L67 and L32 have two Belts

The L32 and L26 have a 4 bolt square throttle body bolt pattern
The L67 and L36 have a 3 bolt triangle throttle body bolt pattern

The L32 and L67 cars have a 3/4" Radiator
The L36 and L26(Maybe) have a 5/8" radiator

The L67 has a Gen III M90
The L32 has a Gen V M90(the gen V is considered much more efficient)
****The Stock Pulley for both Gen III and Gen V is 3.8 inches in Diameter

The L36 has a Plastic Upper intake
The L26 has an Aluminum Upper intake

The NA motors have the cam timing off one degree from the factory

The SC pistons have more space between the piston top and top compression ring than the NA pistons

The L32 and L26 engines have Powder Forged connecting rods and Moly Coated Piston skirts

The L32 and L26 engines' heads flow slightly better than the Series II heads
(thanks to slightly bigger valves and slightly better port design)

What I was trying to find out was are the l26 rods the exact same as the l32. Reason being is because I plan on running nitrous in my l26 motor. I dont want a rod to fail over nitrous. In the facts I pasted above it says that the l32 and l26 rod are the same, are they the exact same or are they made the same way? Im asking many questions because I would rather be safe than sorry. thx for the help guys.
 


they're not the same.

L26 are rumoured to be the weakest of the bunch.

L32/26 are powder forged yes, but different rods.

L32's are shorter and stronger. L26 are longer and weaker.

You must use the same rods as pistons.

N/A rods with N/A pistons and so on. But you can interchange the type of N/A rods and pistons.

Alrite that helped alot. thx man but by chance do you know how much the l26 bottom end can handle, as in torque and hp? thx
 
apparently (Aka take with grain of salt): any M90 build, its good.

If going turbo, be afraid.

N/A? Let 'er rip.
 


just curious doesnt really have anything to do with this but are L67 and L36 valve covers the same like would L36 valve covers work on a L67?
 
did you mean L32 and L67? If so, yes.

But serious: never looked into 3800 + nitrous. Was a thread on it a while back, a serious one. Might want to try and find that.
 
L36 is the N/A 97-03 right? if so i did mean L36, i just wanted to seeif they were in case i go to a JY and see a set i was gonna grab them. L67 don't pop up around here that often and when they do there always stripped
 
They wont work.

If you want a set of L67's i can send one out to you for shipping. They're painted black. Maybe red stripes. Can't recall. PM me if you want them.
