Forged Conrods - Group Buy

No I meant the main bolts holding the crankshaft bearing cradle, they are the same as Evo bolts. The rod bolts for the prism rods are general ARP rod bolts

Why do we should replace them with evo bolt? I think reused stock bolt still able to do its job. CMIIW the main concern is about rods bolt and cylinder head studs, should be replace with ARP

The OEM main bolts wont hold the crankshaft firmly enough if you are going for big power with forged internals. Better to replace them with ARP studs

I see, whats your custom engine spec now and max potential power?

[Anderz]

Main specs are CP Carillo pistons, Prism H-Beam rods, Kennely cams 262 cams, EV14 1000cc injectors, ARP bolts. 2xTD04L-19T billet turbos and flexifuel E85.
Have not tested it yet but should be good for over 500 hp

Wow the car should be ready for 1000Hp if the turbo able to handle boost over 2,5 bar. is it carillo better than wiseco? cheaper or more expensive?

[Anderz]

They were a bit more but not much. Bought the CP pistons because I planned on raising the compression ratio to about 10, however still made them in stock CR

does everyone know what ARP bolt part number that will suit the conrods perfectly, A lot of ARP rods bolt on ebay offered that said will suit the Prism Rods. I wonder which is the correct one. thanks for responds

I am not lazy, just confuse which ARP bolt I should buy. doubtful reference. I think my question is simple and if you can help me just answer the question, i m very gratefull no need to insult me

3/8" UNF thread, with a length of 1.5". The part number will depend on what material you want them made out of. It's up to you to decide that. Maybe you should contact ARP directly?

Roger scott, I ve sent email to the prism seller to help me choose the ARP bolt on ebay. after all he's the one that inform me the bolt size. so I think in the end its better to let him choose for me
