I have a similar build to this, but I have lsvtec with gsr head. im using p73-a0 pistons which are the usdm type r pistons I believe, I cant remember, but I also used my stock rods, I just had them shot peened and installed arp rod bolts and so far ive had no problems. the ls/b20 rods are weaker and tend to break under high rpms compared to the gsr or itr which can spin up to 9k rpms but if you install the rod bolts and have them shot peened you should be okay
