It should fit just fine since you have the same model and engine that he "claims" to. You may have to do some modifications to the charge piping and/or downpipe to fit but the manifold should bolt right on.
Looks like a pretty beat turbo kit though. You could piece one together yourself for a pretty good price with much better parts. But, the problem with that turbo kit and piecing one together is smog legality. I don't know if they would fit, but the only two smog legal kits for you are the Greddy kit and the Edelbrock kit, both which are probably 2-3 times more expensive than the kit you are looking at.
If you can pay someone to smog it for you, it shouldn't be an issue. I, however, like the legal approach, so I opted for the smog legal Greddy Kit.
