Mildly built RB25. A 700HP motor in that car makes absolutely no sense whatsoever. In addition to what was stated above, the chassis would likely need to be reinforced if the owner has any plans of making use of the power.
I think the owner of that car is actually on here. I'll see if I can find it.

You can use other things to blast it, ie, plastic, walnut shells, etc. or even soda blast it. Out of those, I think soda blasting it would be the safest. I wouldn't use sand.
As far as I know, the early 260Z uses 240Z suspension, and the late 260Z uses 280Z suspension. Order accordingly. Based on your description of the fit of the 280Z interior parts, I'm guessing you have an early 260Z.
Someone correct me if I'm wrong.
Someone already did that. There's pictures of it floating around somewhere. It looked horrible.
Speaking of horrible, the car in the first post looks... yeah.
Old guy's hating on the Datsun... and I gotta say he has no taste if he likes the wanna-be speed racer car better. Additionally, can't believe he said stock 240Z steering was "a little tough." My 240z steers with practically no effort.
For the record, I don't see any huge issues with his grammar, spelling, etc. Perfect grammar isn't expected on here, just an effort to make posts easy to read.
