Ok so im trying to decide what i should do with my block to finish my semi built na gsr. Which would be the more reliable route to go with on the block? Jdm itr pistons (maybe bore to 81.5) and arp rod bolts for the gsr rods or should i go with a ls crank and rods with arp rod bolts with pr3 b16 pistons? I already have the crank and rods from a ls and a set of pr3 pistons but if its more reliable to do the itr pistons then i would go that route instead. which would be the more reliable route?

The Head is setup as follows:
stock gsr head not milled
crower stage 2 na cams stock idle design
crower valve springs
crower steel retainers
skunk2 cam gears
skunk2 intake manifold (not pro series)
68mm TB from AEBS
hondata heatshield gasket
ebay intake with aem dryflow filter

 

anyone?

 

put the head on and the itr pistons with a quick re hone. ive never been a fan of the ls crank and gsr bottm. Not to many people do it. go get a tune and take the money from the kit and get a nice header. that ebay one isnt going to cut it with the supporting mods.
