I just accepted delivery of a 2003 Silverstone S2000 w/ 10,500 miles on her . She all payed off and awaiting some boost . After speaking to my mechanic, who by the way works on nothing but Honda's and has built turbo S2000's in the past, well he mentioned to me that I probably shouldn't boost any higher than 4-6 psi for daily driving because the motor is a bit weak and that I may experience issues with the rear cylinder.

It seems to me as though many people are getting big power, reliably or am I mistaken.

Are many people experiencing issues with the motor after going turbo? I'm not seeing it.

Really all I'm looking for is around 330 WHP. I thing I'd be happy with that.

Your Thoughts.

330 hp is very doable on stock compression. Not sure where your mechanic gets 4-6 psi from. You can get decent reliability w/ a turbo setup, but it's never going to be as hassle-free as stock. As long as you keep up w/ the extra maintenance and are dilegent about regular inspections of potention problem spots, you'll be fine

 

Gus, i'm not sure who your mechanic is, but i'm not too sure how many turbo s2000's he has built in the past when he says that the motor is "weak." On a stock block many people are pushing 330whp all day long with no problems on low boost, so you can hit your target with no problem. I am at 342whp @6psi, but this will depend upon what kit/tuner you go with. Just keep in mind that the man who tunes the car is even more important then your mechanic. Without a good tuner your turbo setup will never be how you will want it. For daily driving, on stock compression, many people on the forum have run anywhere between 6-9psi, and many others have upped the boost once they installed a thicker headgasket. Just make sure that you do a lot of research so that you will know how competent your mechanic is before you turn over your new car to him. Good luck with it all.

 

Hmm. Not too sure how much I could trust any advice from someone making this comment, if that is indeed what he said and meant.

 

1. It seems to me that his "nothing but Honda" experience doesn't mean much in the S2000 context.
2. You say he's built turbo S2000's in the past. Well, TWO can be considered "plural". Maybe he didn't do them very well, especially if the "past" was more than 2 or 3 years ago.

It's a tricky business to turbo an S and it's only been consistently, successfully and reliably done without immense cost in the past couple of years. Perhaps it might not be a bad idea to find someone else.

 

what are the type of extra maintence or things i should check or keep an eye out regularly while i have a turbo S.

im just tryin to get as much info about this b4 i make the purchase

 

Things tend to get loose on the added parts. Keep an eye out for these. Keep up with your oil changes regularly. Most FI guys change their oil every 3000 miles. Regularly check your oil levels, preferably every fill up. Regularly check your spark plugs... and change more freqently. I usually change my copper plugs every oil change or every other.

Those are just the basics.

 

Those are the major things. You'll want to keep an eye on all your oil and coolent connects for leaks as well.

The only other thing I can add, is that you actually pay attention to the gauges that you add. They can tell you a lot about how your car is running.


Oh can't help but add in regards to the motor being weak: 19 lbs w/ a head gasket, no measurable knock voltage and so far no reliability issues
