you might have the most miles starting out before boosting. Glad to hear it's been strong for 30k miles. How much power do you put down?

 

Original owner
2005 stock engine
SOS base supercharger kit (i.e., 6 psi) installed at 34,107 miles on August 25, 2010.
Currently at 61,500 miles, went to 7 psi about 2k miles ago but still using the supplies "FVM" piggyback.

It's been extremely reliable. The only issue that comes to mind is that the tension bolt/mechanism seized up on me.

 

420 to wheels .. 14 to 16 psi.. And I do at least 6 to 8 track days a year .. This engine is amazing needless to say

 

2008 S2000 w/ stock engine
SoS N1200 379 rwhp @ 8.3 psi
Supercharged @ 5,000 miles in 2013
Currently @ 47,000 miles

No issues (its seen daily duty, cross country road trips, roll racing, drag strip, Tail of the Dragon 2-3 times a year, and garage duty)

 

You've never had to rebuild the engine or anything in all of that time? That's nothing short of amazing if so.

 

Nothing engine related ever . Same starter same water pump same chain .. .. Yes this car is amazing ..went through a few diffs though original tranny .. Rebuilt 2 gear cause i grinded the syncros

 

stock f20c
ap2 retainer keeper upgrade
100 000 mile before boost,
boost for 300 mile and engine blow
14.5psi 394 whp KW kit

 

boosted mine around 100k (14psi - 420whp) now on about 120k, pressure across all 4 is 235psi (JDM compression), all stock.

 

Boosted at 10k miles, currently at 56k.

So basically no one has put more than 50K miles on a boosted S2000 motor without needing a rebuild? This might be the least reassuring thread I've seen on S2ki in a long time.
