Thanks so much Dave. Clifton

I got some boxes of Koni 28B-1130 shocks from a Z car friend. He delt with Konis years ago but doesn't know what the app is for. They have been in his garage for atleast 15 years. I have looked everywhere and have seen a part cross reference from KYB for a 1979 200sx, Sunny, and a B310 but this is questionable. I was hopping that someone with a B310 or 180SX/200SX could tell me if these measurement are the same as theirs, assuming they happen to have a rear shock laying around. Thanks, Clifton Extended length 21.75" Compressed length 16.25" Bottom eye .464" / 11.85mm Top pin .385"/ 10mm

I should add. Once the compressor wheel is off you will have to give a tap on the compressor shaft end to get the turbine out. It is only being held in by the piston ring at this point. Same to get it back in. Push it in as far as it will go, make sure the piston ring is seated in the bevel as far as it will go and tap it. I use a peice of hood. A hammer handle end works too. You will need a small tip snap ring plier to remove the snap rings that retain the bearings iside. You may have have to grind the tips down. A 6 point 14mm socket works better than a 12 point on the turbine end.

I have done quite a few turbos and never had a problem. You don't need to balance. Compressor wheels and turbnes are balanced individually. Compressor wheel on th eback, turboes on the fastener. Only Turbonetices that I know of for sure balances their assemblies. They take the weight off the compressor nut and usually not much. There is not one local turbo rebuild shop in my town that balances. Rebuild kits are cheap. When changing the piston ring on the turbine. Put the end gap up. There really isn't much to them. Compressor seals differ but bearings and thrist washer are all the same on small shaft Garrett, what you have.
