I have 3 of them if you wanna buy them off me, $5 (includes postage) and its all yours. I dont need them since I run a Picco system on my Evo3.

Off topic DJ, where is a good online place to source Picco Evo 3 conrods? Part number or batch numbers for stronger/strongest ones if thats possible?

Cheers

Very good question!! As far as memory serves me, you might be able to get some from rcmart, or from Sam @ Kamikaze Toys and Hobbies.
I dont think they are supporting it any more since the rods are as good as paperweights I still have only one spare left after I finish getting rid of my Evo3's pinch just around TDC, still can't turn it over by hand and it's got an extra 0.1mm shim in it. Secret of mine is that the piston is from my first Evo3 modified from AB Mods, and the sleeve is from a 2nd stock one I got. Perfect fit for each other, and I copied over the mod but added a little more timing to the Boost port.

Sam no longer has the rods in stock for the .12 evo3. He's working on getting some from a source outside US.

To the OP, the best pipe for the Evo 3 is the 2651 Picco pipe. Using anything other than that will not get you good results.

GREGORY!

one off topic question.
what do you do in your motors?first picco's then rb that you have not run in right.

Not sure what you are asking.
But I'll answer the way I see how it is asked.

First engine was a modified Picco Evo3.
Then when that went out, I tried a stock Evo3. That went out the window even faster than the first one!! (2 months or so)
Then I got an RB T10 - absolutely loved the power and tuning of it! Actually had to make it rich (either the bottom or top) to make it more controllable.

BUT, with these engines, I thought I had broken them in correctly, but I didn't monitor the temps/keep them high enough after the 3-4 tanks or so, so I believe it started off well but then because the temps were not high enough to break-in properly, it actually messed them up by basically doing this:
Because the sleeve expands faster than the piston itself, in the beginning it was fine/where it would probably be at it's maximum diameter. After the 3rd/4th tank, that diameter was naturally reduced due to the lower temperature and because it was much tighter, the piston probably wore away too much of the sleeve and so the ability to create a seal was lost once more heat got into it.

Now that I strongly believe that this is the case, I swapped out the unmodified sleeve from the 2nd Evo3 and used the piston from the first modified Evo3. The sleeve was just as tight as a brand-new set, and now I am STILL in the process of getting rid of that pinch. I still can't turn it over by hand without hitting the pinch almost at TDC and this is now the 4th tank since "Frankensteining" it. Plus I modified the stock sleeve using the same measurements from the first Evo3, but I increased the timing on the boost port (by mistake, but it sure does fly!!!)

Just noticed that the OP posted for an Evo4. The 2651 pipe is still the best. I got a 2651 pipe with my Evo4 Edo combo. For the Picco .12s there is no other pipe that works better.

if the nova gasket feels tighter, use this instead of the picco one. But as
other people are saying, do yourself a favor and buy the 2651 pipe. Or at least
if you could find an older picco/mega #2607 or idm #2617 pipe set at a lower price, with the idm being a slightly better choice for the evo4 (gives more top-end).
