Hi,

I just purchase a Jdm integra type-R long block with a PR3 head but the block and conecting rods are stamped P72. Isnt all Type-R parts P73?? Did I get screwed?

 

i think p72 is 96/97 p73 98 - 01

actual block stamp and cast is shared w/ b18c1 GSR . Yes all GSRs and ITRs will have the same P72 blocks. Difference is in the crank/pistons/rods!

 

when you say crank, do you mean the weight differences, aren't the rods the same? and i know pistons are higher compression... ???

 

Rods and crankshaft are the same castings, they're just machined differently. Check out your oil pan too, P72 stamped on it.

 

jdm compression pistons are 11:0:1 and th will have an r simble on them to show that they are type r rods and the weight diffrences are the same im pretty sure

 

JDM Integra Type-R pistons (P73-00), are 11:1CR. USDM Integra Type-R pistons (P73-A0) are 10.6:1CR.

They don't have an R symbol on them, they simply have the codes stamped on the dome.

The only difference between Type-R and GSR rods/crankshafts are the Type-R components are machined differently, they're the same castings.

They might (the rods) start from the same casting bu the "R" rods are supposed to be forged and have that R on the beam.
