I have a 2.0LR and want to go 2.2LR. Which one should i go with? Manley Turbo Tuff Billet, K1 Technologies Billet or Eagle Forged?

 

Go with Eagle. You'll need 150 or 153mm rods in. 4g63 block. Or 156 or 159mm rods in a 4g64. Any of those rod lengths is fine to rev 9500ish.

 

Why Eagle? The other two are Chinese/poor quality? i don't believe i will rev it more than 8000rpm with a g30-660 but is still good to know

 

I don’t have any personal experience with it but don’t forget about the callies 94mm crank. Only heard good things about it so far.

 

I have personally seen TWO manley cranks fail at the 4th journal.

 

I have a Callies 94mm billet crank going in a 4G64.

 

Run a cheap oem 100mm crank if you're only spinning to 8k.

 

There are plenty of good options out there. Most cranks for these cars are built to favor strength over oiling now. Some earlier ones were the opposite. A number of cranks were broken along the way as tuning was being figured out for this platform. Rattle anything hard enough and it will break.Learning curve..

Its well known that the 100mm cranks of any type have less material for strength because of the stroker design and should be tuned well, below 700-800hp or so. To this day TS comp still builds plenty of manley 100mm engines that run well. If you are breaking 94mm cranks less then 1000whp+ it sounds like a tuning issue. If the crank didn't break, something else is going to.

There are a few roadcourse/auto X cars that have broken stock and 94mm/100mm cranks. But its important to realize they are running a big tire, launching it all the time on a less then ideal surface and encountering wheelhop alot. If you load/unload the drive train a something will eventually break.

With that being said I'm running an old manley billet 94mm crank that favors oiling over strength without any issues.

I'm going to 2nd Abacus here, since I think we have the same miles / years on Manley Billets. I'm at 6.5 years and approaching 60k miles with equivalent torque, no issues.

 

This is my setup from Curt Brown

4g63 Block
94mm Eagle Crank (2037005900B7)
JE Asymmetrical Forged Pistons (297479)
Eagle Extreme Connecting Rods (CRS5900MBXD)

 

Or don't because who wants to spin rod bearings in every 15k miles

 

What happens with the 2.4 crank that destroys bearings?

 

Callies is an option that i did not know of and they are built in the States. Not many companies sell this item though...

 

The rod ratio sucks with a 100mm crank in the 4g63 block, and regardless of balance it vibrates a lot due to the poor rod ratio.

 

holy **** my 2.3L 100mm crank rattles every bolt out !!! Thinking of going to a 94mm crank and keeping the same rods
