Hello guys!
I have a big big problem!:
I upgrade my S2k i installed turbo with all the good parts (pistons, rods ect..)
But it's already 2 times damage in my crankshaft bearings (rods bearings) WHY?
Is somebody have a clue?
my S2000 year: 2002
Thank you

There is a bit more to look into.

What about the bearings are failing? Are you spinning them? Or are they scorched, broken?

Also, a bit more details regarding the pistons, rods, etc. Compression ratio and amount of boost from the turbo?

 

also what kind of oil are you using? have you done any measurements for the crank or rod bearing (plastistrip is your friend).
Did you balance the rods and pistons? did you rebalance the crank with the new rods and pistons set?

 

I heared that there is problem with the banjo oil bolts that from year 2002 they change it to 4 holes... somebody know something about it?

 

Banjo bolt is 1 hole only. I can't image a 4 hole banjo bolt.
Do you mean rod bearing? The upper rod bearing bolt might have 4 holes for oil passage. Don't know exactly how many holes though.

 

Yes i mean the rods bolts... co's i have only 2 holes and i eared that they change it to 4 holes....
Do you know something about that?

 

The banjo bolts have nothing to do with the rods. A late model oil squirter bolt now has 4 holes in it rather than 2. They can be installed in place of the old ones. Changing these bolt will not fix your rod bearing problem.

Not sure why your rod bearings failed the first time but if you did nothing to the crank and just replaced the bearings, they will definitely keep failing over and over again. Something is wrong with your crank or aftermarket rod. You may need to swap out your crank and have the big end of your rods rebuilt/resized to fix the problems. It is NOT a problem with bad bearings.

 

Is somebody can offer me set of rods for my turbo S2k?

 

Is it even tuned?

 

Sure! aem ems

 

damn that sucks i hope you get it fixed. Bump for an answer.

Sure shut me up. I have nothing further.

EDIT: A thaught occurs. What were the rod bearing clearances?

I got rods! but now i need 1 size over rods and main bearings....... anybody? here we don't have!

 

Order them??? You can ship stuff everywhere

 

I don't know of any company making oversized bearings for the S2000 yet. Let me know if you find them.

 

Detonation is my first thought.. it shows up on the rod bearings often. Do you have a recent log of a 3rd gear pull?

 

No i don't have any log.... still looking for crank...

 

i have a crank and head for sale 600 for all of it includes cams block and crank bare

 

Do you have an Email ?
