hi im having bad time deciding what to do soo i need help of you guys ...

i have everything to build the engine i just have to order the pistons , but before ordering they, my builder says that he prefers to build the engine in LONG ROD configuration because it can rev to 8500 rpm without problems.. i already have 150mm rods .. the problem here is that i have crower billet i beams rods these are very good rods..

the problem is i dont have money to buy another set of rods of that price range.. the only option that i see is to buy manley 156mm rods but not the turbo tuff ones... i can buy the H beam ones that are cheapier like 365 dollars...

so my question is... what is better for me

built the engine with the 150mm crower billet i beam rods that i already have and rev the engine to 8,000 rpm and can have 600+ hp in the future dont know the time...

or

built the engine with the 156 manley h beams rods and have less quality rods and the limit of 600 hp but rev the engine to 8,500 rpm....


Please Helpp i need good answers now i stopped the engine built because im not sure what to do ..

 

I would stick with the Crower I beams, no need in switching. They are just giving you their opinion on what they like the best.

 

he told me that is just to rev the engine 500 rpm more but idk if that helps a lot or not... thats what have me thinking

 

You would need a big turbo to even take advantage of the extra RPM, like something to make in the 850+whp range. I don't think it is worth it.

 

i have a 6262 JB .. he says that the advantage to the extra 500rpm are Big because is 500rpm more of power.. but in my case i just want 550 or 500 hp he says that the reason to rev it 500rpm more is to have more power band across the gear... i dont know something like that

 

need opinions ppl ... help

 

You might benefit from the extra 500 RPM if the 6262 doesn't fall off at higher revs. I don't know what a 6262 powerband looks like on a 2.4L, but I don't think it'll be making any power over 8000 RPM.

If that's the case then you won't need the extra 500 RPM for this setup. I don't know what your future plans are with your car, but I doubt you'll need the 500 RPM.

Another alternative to increase the powerband is to install a 4.11 FD. That should make your gearing more comfortable. It's a more expensive option, but it's a good one.

 

so if in the future i want to use a 6466 ill need the extra 500rpm or not

 

Rebuilding an engine when your low inadequate rods break is a lot more expensive than buying the right beams to start with. I would go with what you have. It's an opinion of your builder, and with your goals, not necessary to go long rod. Enjoy a safe, reliable ride with lots of HP with the peace of mind from having great rods.

 

Yes, you would want that extra 500 RPM with a 6466.

 

Pretty much my setup right there. my 6265 starts to drop off a tiny bit before 7500. i havent been to the track yet but the new 4.11 i have feels good to me

 

Yeah if the 6265 starts tapering before 7500 then there's no way a 6262 is going to be able to make power beyond the 6265, so the extra 500 RPM would not be necessary for this setup.

When do you hit full boost with your 6265 silver9mr?

 

I don't have the boost chart but I hit 440tq at 5k so I'm hitting full boost In the 5k area

 

Thanks will use the crower billet i beams !! But later i want a 6466

 

Then you'll want the 4.11 FD to compensate for the "lack" of RPM.
