Rebuilding an engine and wondering about crankwalk

[dj_lethrow]

I have a 1990 plymouth laser RS Turbo and I am in the stages of getting it out at the moment and is there anything I should worry about when rebuilding I plan to rebuild the internals so I can run a bigger turbo and have the peace of mind that the car is ok. Will my original crankshaft hold up?

4g63 crank has held 1000whp your should do just fine.

The 1Gs are generally believed to be less susceptible to crankwalk than the 2G cars. This may be because there is no crank angle sensor to get killed, however.

There was an interesting rebuild done by a member here (noslaser) that involved extremely precise machining during the rebuild; you might want to look that up. There's no absolute evidence that his technique actually prevents crankwalk, but it looks interesting and logically makes a good bit of sense.
