I have an 89 sunbird non-turbo and i was wanting to swap in the bottom end from a turbo motor, as i heard they were stronger, but when i checked @ autozone and advance auto parts for the crank, they have remanufactured kits and one says "forging # 399" and the casting # to the crank i have now for the N/A is R90280399 ... so are they really the same cranks? and they also have 2 others, but they dont have forging #s for it, the link to check them is... http://autozone.com/servlet/UiBroker?UseCase=C001&UserAction=performSearch&Parameters=Auto+Store%7C%7EREGULAR+PARTS+LOOK+UP%7C%7ECrankshaft+Kit+Remanufactured

hope you guys can help... thanks in advance

Lotsa myth and magic around the turbo crank. Don't bet it's anything different than the N/A part. Rods and pistons, however, are different.

Search in this forum for the 2.0FAQ. I know theres a section in there about going from NA to turbo, but I don't know if it will be any help to you.

Ok, so im guessing i can use the N/A crank, well the Froging #399 crank, and then use rods and pistons from a turbo.. so itll be a complete turbo bottom end in a N/A? will they swap in? anyone have these for sale? if so how much for the rods and pistons? individual prices if you could please, thanks
