How many pounds of boost can the stock engine handle? My biggest fantasy is an s2k with a turbo pumping more than 20 psi. Will rebuilding the engine ever make this even remotely possible?
Also, all you guys putting turbos on your s2k's, you rule.

 

Ohyeah, if you rebuid it good enought it can take anything. I even heard of a Skylive running 42 pounds of boost.

 

A Mike Simon built S2000 motor can boost at 15-20 psi. You just need the engine management and fuel upgrades to go with it. The stock motor with no ignition timing can take about 6-7 psi on pump gas. A safe number with retarded timing has not been seen yet...but my car is finishing up it's tuning tomorrow. We expect to run around 9-10 PSI on the Speedcraft kit with eManage (with ignition harness) and 440cc injectors.

 

I've got 785cc injectors, an AEM, and two pulleys... an 11 psi one, and a 13 psi one... ready to throw on my Vortech SC'ed S2k.


"She canna take anymore, Cap'n!" is what I expect to hear.

 

skylines are a different story, they're known for holding boost. Hey, does anybody know of any good tuners in the tri-state (around NYC) area?
