im in the middle of buying parts for my motor build and im trying to save money where i can without sacrificing peace of mind.

the car will be well over 600 flywheel hp.

do i use the stock rods with arp wavelocs or do i spend the extra couple hundred and get eagle h beams?

$65 vs 126 vs $400?

is the 190,000psi enough or would the 220,000 be more suitable?

off boost the car will most likely be a dog and will only see stress for short bursts on the street and the occasional trip to the track.

 

how high do u plan on reving the engine ?

if ur keeping the rpms fairly low say 5,500-6k max id trust the stock rods with good bolts
as long as the stock rods are properly resized ,maganafluxed and stresss relived


byt the time u pay for all that ur prolly at half the cost of a decent set of aftermarket rods

btw stock reworked rods with arp wavelocks is what i have in my twin turbo iroc engine ( the old engine) and i trusted those to 23 psi and 50 shot of nitrous .

i limited rpms to 5,800 though

 

Ill go with bolts rod bolts then, i get a decent discount at the local machine shop so ill go that route, i am not going to rev it past 5500 or so...

 

be sure to take into account the cost of the crank abd pistons u are using u dont wanna cheap out by 200 ucks and have the cheap parts ruin the more exspensive ones

 

Pistons are 470 for the set and im using the factory crank. Its going to be a true budget build

 

use factory pistons then or buy a set of speedpros for 1/2 the cost speedpro forged are dirt cheap.

top ring gap and tune are key to making cast pistons survive, cheap speedpro forged pistons will hold up just fine

 

the speedpro powerforged pistons are what im going to use

 

u should be able to get sp forgings for around 220 bucks why are urs so exspensive

 

They are the powerforged turbo pistons with rings... only jegs lists them

 

id just use standard sp forgings and save the money what heads u using what chamber cc , if its a ;large chamber head id use a standard sp forged flat top with 2 reliefs

 

Iron motown 220s, theyre 64cc chambers. If i can find some that are closer to 8:1 id go that route

 

For future reference i bought eagle h beams and dss forged pistons
