LS V8 swap into a Boxster S

Smallblock454, thanks so much for the links! Very inspiring reading!

I actually read all of the posts by BoxsterLS376. That is what convinced me to go buy this tiny beast of a car. Lol! I had no idea I even wanted one until I heard 50/50 weight distribution, 6 speed, cheap oil changes, etc.

Very much appreciate the link for the tach correction unit. That opens my field of possible engines so much. Stuttgart Muscle had indicated I needed a 58x reluctor wheel. Also found out somewhat recently that a Vortec is also workable. Once you start to research a whole world of swap ideas come to find.

Now to narrow it down to a proper displacement. "No replacement for displacement" comes to mind but then reality sets in. I don't need 600+ horsepower at this stage of life. I just love the sound of a proper V-8 and a stick shift. I'd be happy with anything equal to stock for now, or perhaps a bit of a bump to say 350ish or so.

When changing a cam what does it take to change the computer fuel maps and timing adjustments? Is this already done by the computer or does this need to be hired out to someone with a dyno? I'm old school. You advance the distributor a few degrees and drive it around the block to see if it pings....

Also wondering if the stock harness is easy enough to modify or if I should go with aftermarket? I am an electrician and can follow diagrams so.....

Hang in there gang. Any moment I'll get going with actual progress! Still tearing down and cleaning up at this point.

No.

Yes, but the dyno is not the important part. The person needs to know how to remap the ECU you're using and needs to have experience in doing that.
