Nice car looking for a s2000 myself , OTOH never heard of the slang term marrow but Id assume its some sort of bad to bone thing or runs bone deep .

But back to the s2000 yes my budget has me looking at alot of AP1's and a few higher milage AP2's . Ive seen some mighty hard trashed ol girl's makes me wonder if they wouldnt cost more to bring back a 100k+ miles s2000 or just look for a older low mile one .

I have the 4 door version of the SI now (FA5) its ok I love the honda powerband but Id like a lil more

 

Its hard to find a legit one these days..Most are high mileage or just thrashed like you said,But id honestly shoot for a 2000-2003 ap1 with a little higher miles I mean it is honda. Just look around you'll find one. Nice i love those si's so sweet.

 

good advice get an AP1 and retro fit it
