About 4-6 months of late '88-early '89 models are 9:1 the rest are 8.6:1 compression.
So no need to worry about the compression, the factory cast piston rings would be your concern though, but with good fuel control your safe their for awhile.
jgstools.com/turbo there is a do it yourself kit and a log manifold already welded up with external wastegate for $305.
