yeah, but the thing is i only uprated the pistons because it blew up before when it lost oil pressure. my car's an evo 5, and it's had lots of leaks here and there and finally it gave up on me even though i wasn't really beating on it. with these guys saying that the 50 trim doesn't require a built motor, i decided to only get the arias since those were the only choice pistons being sold around here, the stockers weren't available. the eagles cost way too much too but since i have stock rods from an Evo 7, i decided to use those instead.

money IS a concern, as i am not raelly trying to build a monster anyway. just got a 50 trim to add up a lil extra kick.

 

I feel you did the right thing for your budget.

The weak point of the factory rods seems to be the bolts. If you used better rod bolts, you should be ok. In fact, I don't trust the consistency of the (Chinese) metallurgy in those Eagle rods (have seen a couple fail under moderate conditions), so unless I were going to use a premium billet rod, I would probably stay with the factory rods.

If I were going to make a choice between pistons and rods, I would change the pistons. Forged pistons are more durable, and absorb more heat, which tends to reduce the onset of detonation. Cracked cast pistons are a real concern with these engines, and I'm dealing with that now.

If you're putting together a 50 trim setup, this should be fine. Just remember that no parts are strong enough to withstand a good deal of detonation.

 

Thanks for that, Ted. I do believe in what you've said, that if one were to change rods he should go for the premium ones. The car held up for so long already, and when it blew up, it all came back to me, that I've been dealing with low compression on cylinder #4 for years and never bothered to look it up, just kept changing plugs on that cylinder everytime it asked for it.

As for the set up, I have no plans whatsoever to go past the 50 trim. One can't even max out that turbo with the stock block as people said when I searched in this forum. I have good faith that this set up will do the job, as I don't drag race nor track the car anyway. I just wanted a little kick and the 50 trim has done the job well. It's all a matter of how long these stock rods / block will take the abuse. I say give me at least 3 years, and I'll be fine with that. :-)

 

even on a 35r ull be fine.. its all in the tune

 

thanks psphinx... guess i can breathe a lot easier now man!
