H-beam rods with Speed Pro Pistons, wrist pins wont work...

[91civichatch2571]

I just bought these rods and pistons. I was assembling them and the wrist pins that came with the pistons arent floating. They need locks while the rods have bushings (meaning they are meant for a floating wrist pin.) Probly a very stupid question, but this wont work will it? Im gonna need to end up getting another set of new pistons. Has this ever happened to any one else? Its like the pistons need a C-clip to hold in the wrist pins but theres nothing there, they just slide in and out with a little effort. Also, does anyone have any D16 pistons with a ~9.5:1 compression that will handle a turbo? Either hyperutechtic or forged?

I see you have the same problem I had with my eagle rods and CTR pistons.

you have 4 choices

1. sell the pistons buy new ones
2. sell the rods use OE
3. have the pistons machined to accept a c-clip
4. Fabricate a wrist pin retaining tool (like I did)

how I did it is I used a threaded rod, 4 nuts, 2 washers and some permanent thread lock.

cut the threaded rod to be 2mm (or less if possible) shorter then the pistons. you place 1 nut at each end at so they are flush with the opening of the wrist pin hole. place a large washer on the rod (may be needed to be trimmed to fit flush) and tighten with an other nut.

this way the pressure is exerted on the nuts not the piston itself to bend it out of shape.

once everything is the right size assemble everything with permanent thread lock.

trim sharp edges with a file or small grinder and assemble as normal.

you got any pictures of that concoction? Do the threaded rods just hang there and shake all over when the pistons are going up and down? Im not too sure if I like this idea, although it is creative.

no there is enough pressure against the pistons to keep the retainor in place, in my case the bolts I used fit inside the wrist pin and the pin kept if from moving... not sure how it's going to work... but I have a spare block in case shit hit the fan.

sorry no pics

Oh, you havent ran it like this yet? I think I might have found a set of SRP pistons for $150 though so thats cool.

Same thing happened to me. I just ended up buying some SRP pistons and selling the other ones. That was the easiest thing to do.
