Does rod only make me a nimrod
Ok so I have a 04 engine with 47k on it ready to swap in. But I want to make 250 today and maybe 300 someday.
What would be involved in just changing the rods to h beams from ebay with arp rods.
What would I need from a work/parts department. I did search and I know I need:
Head gasket(what kind should I look for cost matters)
oil pan gasket
H beam Rods
http://www.ebay.com/itm/MAZDA1-6L-1-...item5d337c1315
Rod bearings (what kind should I look for cost matters)
things I might need what do yall think
oil pump
timing belt
Do i need any machine work.If i keep original pistons do i need to change rings? I figured I would not even take out crank.
Do I need to replace head bolts. arp?
Is it silly to not change to lower comp pistons?
http://www.ebay.com/itm/94-97-Mazda-...item19ce6ff3c3
Are these ok?
what about wrist pin. If I keep stock piston will stock pin be ok to reuse.
New piston new pin?
Are cheap 94-97 like these worth swapping out

I cant see the last reply but if it had to do with searching I did.
What I am trying to figure out is with a newer engine can I just change the rods and if so how and is it a good idea.

read this one and many others but none where as new of an engine as mine or had the higher compresion of 01-05 engines.

Even if you keep the high-comp slugs, I would have the block honed and replace the rings. I would also do all of the bearings, and not just the rod bearings.
Stock pistons are fine at 250, but they are probably a little fragile at 300whp. You will have very, very little margin for error in the tune before you crack a ringland, moreso because it's a 10:1 motor.

oems will cut 250
and 300
at 350 you should be building the car RIGHT and not skimping on things, and if you are then you're a dumbass
But like you guys, I'm kinda curious about the fleagay pistons, though I probably wouldn't run them on my cars ever, even if they weren't that bad. Too many OEM ones available at the local pick-n-pulls to experiment with ebay stock replacement pistons.

I broke a main stud at 350whp. It destroyed the entire motor. Decide for yourself if you want to risk it over $80.
As far as I know, nobody's ever broken a factory head stud, but that's probably because anyone who's making much more than 300whp isn't stupid enough to risk running a factory head stud. I'm not tempted to be the guinea pig like I was on the main studs, so all of our motors get head studs too.

Yeah, everyone trusts "their" rods, it sounds like who ever buys the pistons will be the guinea pig, but I'm going with some stockers. I haven't heard anyone say "**** no" yet though.

Any engine build I will do is not in the near future, so I will keep researching.
And yeah, sometimes "their" rods, for instance, are probably manufactured at the same factory probably using the same design as the name brand ones (since they don't worry too much about "IP" laws in China).
Maybe "their" pistons suck, but it might be you could get nearly the same thing for 1/3rd of the price.
