Hello, new here and looking for help finding a part/looking for advice.

Long story short, it's mom's car. Her boyfriend destroyed a crankshaft bearing while street racing (after I explicitly told them it should not be driven), he bought a jdm b18c off hmotors, did nothing with the engine before swapping it in, swapped the supercharger over, drove it a couple times, ran seafoam through it (he put 3/4 of a can into the fuel), and now it smokes. I drove it for a couple fill ups to make sure the seafoam got burnt through. It still smokes. He came to the conclusion it was the valve seals, so I decided to change them myself.

I found a cracked retainer while changing them. So here's my question, what the hell retainers do I buy. I've searched for what seems like forever and can not get a definitive answer on what retainers to buy. I can find info on the usdm gsr and both type-r's, but no info on the jdm gsr. I thought the heads were different between the jdm itr and the jdm gsr, or can I buy itr retainers?

Also, as far as advice goes. Should something be upgraded because of the supercharger, or is it fine with stock internals. It's a Jackson racing supercharger, about 7psi I think.

Any input is welcome, I just want to get this back in the road for mom.

#1. OEM retainers for any 94-01 USDM B18C1 (GSR) OR C5 (Type R) will work. They're all the same.

#2. If you're supercharged, then you need to get it tuned.

Thanks for the response. I know it needs a tune, but just wanted to be sure the stock cams and valves and such would be fine. Also, I thought I'd read somewhere that the gsr used single springs on the intake side, where as the type-r used dual. Is that not the case, or does that not effect the retainers?

I also see you specified USDM, but this has a jdm b18c, just want to make sure your answer still stands, I could see how that part could have been skimmed over.

Your response to the valve springs is correct, but the retainers themselves are the same.

As far as JDM vs USDM, no difference.
