Alright heres the deal. I got a 1993 GSR (B17A1) I recently pickde up a spare B17A1 short block that had a spun bearing for dirt cheap to build up on the side waiting for my bottom end to start showing signs of the fails since its got 195k on it.

When I took the spare block apart, its got a bent rod on cyl #4. Everything looks fine except for the spun rod bearing and the bent rod. So heres what im asking basically.

I want to put P30 pistons in the spare block, and since i only have 3 good p61 rods, im gonna need another set of rods to (Highly doubt ima find a p61 rod floating around)


1. Can I use P30 pistons w/ P30 rods? The crank is a PR3 of course so I dont know if it will work or not.
2. Can I use PR3 pistons w/PR3 rods?
3. Can I use P30 pistons w/PR3 rods?
Either way is fine, im only looking to raise the compression a tad bit when I do the rebuild, not going for no crazy all out build so thats why im gonna be using either of those.


Lmk on any options I have, I dont really wanna reuse any of the p61 pistons I have and i dont want to just have to take a rod and piston out of my current motor when i put the other block in just to complete the set (since im wanting a higher c/r anyway)

Thanks alot for any help.

 

Never heard of P30 rods. But if you mean the B16 rods then, no you probably wont want to do that as they're 2mm too long. But you would get a nice bump in compression if you put the P30 pistons on the B17 rods.

 

B16 rods will not work. PR3 pistons will work on b17 rods. CTR pistons work too.

 

hey man, i have a clean good condition b17a1 crank, a set of good rods, and a brand new in box set of p30 pistions i'll sell you. shoot me an email if you want.

I PM'd you.

Otherwise thanks for the help guys.

 

I actually may have a couple of P61 rods spare pretty soon here. I think I hydrolocked my engine and when it goes back together it's getting some Crowers or something. I put it together with polished/shot peened OEM rods with ARP bolts.

 

If you wanna spare just 1 of them (Or the set of 4 if need be) then ill buy either or... Cash in hand shoot me a PM man.

 

Same problem, i know this is an old post but need a rod, what can we work out
