LS V8 swap into a Boxster S - 986 Forum - The Community for Porsche Boxster & Cayman Owners

That Honda swap is pretty neat, and it does make a lot of sense. The Cadillac V6 mentioned in that thread also sounds like a good swap candidate.

Hi Guys

I was able to purchase the used oil pan. Sheet metal, no name brand or numbers, about 5" deep with remote oil filter mount and lines included. $200 and helped out a friend so all in all a good deal.

Also ordered and received (yay amazon!) a crank pulley for a front drive LS4. Super narrow and only a single flat belt drive. That will save a bunch of space and therefore cutting, I think.....

Still looking for a car type LS intake manifold, and looking at stand alone ECM's. So much to choose from with options all over the board.

Met Sam last week and he knows some guys opening a dyno shop that are LS savvy and may have parts or good sources at least. He is busy now soaking up info from my Bentleys manual. Lots of good info in there to go along with the 101 Projects bible.

Had a buddy refer to the project car as the Frankenboxster. Kinda like that but WAY too long for a license plate where you only get 7 characters. Actually looking for ideas how to create a red letter "L" to go in the trunk letters so it reads Boxster L S. Ideas on that?

I got my coolant pump set-up from Davies Craig out of Australia. Very nice machining and seems fairly straight forward but lots of control items to sort out if I'm using that controller and the factory ECM and the stand alone ECM. They all need to be able to run the cooling fans. Gotta make them all talk nice to each other.

Still researching ECM's. And intakes. Will likely need to convert to a cable operated throttle. Too many options but leaning heavily toward the Fitech unit.

The adapter from kitcarchassis.com is taking longer than anticipated but they had issues with their machinery. Stuff happens! Should be on the way this week. Fingers crossed.

Once I get the adapter I can bolt everything together including the balancer pulley and get going on mounts and clearance issues.

And now, back to the show!

Can anyone recommend an inexpensive scan tool to use while the swap is on-going? I imagine I will need to clear codes repeatedly while looking for the right things to disconnect or hook back up again. I can borrow one from the local auto parts store but not long term and it would be convenient to have one on the shelf when needed.

Thanks!

Hi All

Made my first mistake I can't fix on my own. (Thought that might get your attention.)

Moved parking brake crank assembly and got it all tidied up and workable. Same location but 2" forward from stock. Easy fit! Went to drop the body over the engine one final time and bolt it all in. Got the rear mounts in and went to the front only to discover the strange sound I had heard while lowering the lift was the drivers side cable getting caught on top of the head and stretching it out. Added about 3" of length and unraveled a bunch of housing. Found and ordered a used cable on the E-site. Should be here in a week.

If that's my worst issue I'll be happy! Getting closer to an initial start every time I work on it. Next is wiring and fuel lines. Still moving along and hoping to have it motivating under it's own power in the spring.

Cheers!
