FMuscle Posted August 16, 2014 Share Posted August 16, 2014 (edited) I just want to know the differences between 1st gen, 2nd gen and FHE rods. I never had one of each in hand and I read different specs everywhere on the interweb...What I have now is a 1st Gen FE. It is mostly agreed that 2nd Gen is weaker. Some say FHE are stronger, some say they're the same as 1st Gen....And if one was to gauge strenght based on pressure (Boost), which one would be the stongest?Found this pic, but it doesn't mention which 5E-FE gen it is...

5e colin Posted August 16, 2014 Share Posted August 16, 2014 wel 5efhe rods will withstand 1.4 1.5 bar of booost i have tested this fat rods are fhe and scinny are 5efe i still have some ere if u need fhe 1s Quote Link to post Share on other sites
Sudden Posted August 16, 2014 Share Posted August 16, 2014 This topic is highly controversial. The picture you posted is only one of a pair. The fhe rods are thicker front to rear(of the engine not the car) and thinner exhaust to intake. In my opinion, because of how the rods rotate on the crankshaft, the forces acting upon the crank would indicate that a wider rod (exhaust to intake) would withstand more strain, while a narrower rod front to rear of engine will be more "aerodynamic". Regardless, bad fuel/poor or no tuning causing detonation will destroy any rod. I recently built my engine using 5efe dis rods because i believe yamaha/toyota wouldn't step backwards in their parts design or construction. My pc is down, would be nice if you could source and post the 2nd picture to match the one you posted. Quote Link to post Share on other sites
Sudden Posted August 16, 2014 Share Posted August 16, 2014 (edited) Sorry double post. Edited August 16, 2014 by Sudden Quote Link to post Share on other sites
FMuscle Posted August 16, 2014 Author Share Posted August 16, 2014 Found and added the pic to 1st post. So 1st gen and FHE are definetly not the same? Damn Wiki, letting me down... LOL I just replaced the pulley on my SC14 to push 10.5 Psi (sorry, I don't get that bar s*t yet, I just learnt how to use kilowatts so bare with me, bar is next ), so I want to make sure that the rods can take it. I read somewhere that the stock 5E internals can take up to 12Psi, but again no mention of which 5E. Quote Link to post Share on other sites
Sudden Posted August 16, 2014 Share Posted August 16, 2014 (edited) The 3e, 1st gen 5e, and fhe rods all look the same. The 5efe rods in that pic are the dis rods. Same ones im using. The width in the 2nd picture now shows how the fhe rods are skinnier than the dis rods, in my opinion where it counts the most.

FMuscle Posted August 16, 2014 Author Share Posted August 16, 2014 Yeah just saw that. Funny how it's not the same rod in both pictures... I thought it looked shinier... i still have some ere if u need fhe 1sHow much for them? Quote Link to post Share on other sites

Sudden Posted August 16, 2014 Share Posted August 16, 2014 Pic 2s 5efe rod next to the fhe rods is exactly how mine were when I compared them, that's why I used the dis rods Quote Link to post Share on other sites
gorganl2000 Posted August 28, 2014 Share Posted August 28, 2014 when people post pics of bent rods they are normally bent on the side (front to rear as per above)...so seems that the 5efhe rods are stronger than the 5efe/thinner rods in that event http://board.tercelonline.com/viewthread.php?tid=38598 some more pics there Quote Link to post Share on other sites
