I have an S4 NA motor with 215,000 on the factory installed engine. Its getting replaced for a MARVELSPEED ported engine, T60-1, and a Haltech. Its has been given hell daily and comes back for more. Its to old to rebuild, but works too well to just sit and lose compression. What should I do with this immortal engine?

 

why is it to old to rebuild?

if your not going to use it sell it

 

Don Marvel does not like to rebuild engines with over 150,000 because the housings tend to flake at that age. Besides I have another with only 120,000 at the shop right now.

might be hard to sell, but i'll take offers

 

go cart then
