so i want to buy another s2k soon and i wanna boost it this time. i want a reliable build that wont be in the shop all the time. im looking at around 350 minimum and 450 max, as far as reliability goes, i might go with a SC. but my questions are

-what would be most reliable (SC, turbo, pro charger ect.)

-what internals would i have to build

-what kit u recommend

-any reliability advise

also tell em why u think so to any of my questions. thank you

 

Recommend you take the time to educate yourself first by reading through the FI thread. I have been doing this for the past year or two and am now ready to move on the SoS Stage 1 Kit. Getting my clutch upgraded in the next week or two and then on to the SC. Already have an exhaust and the car has had the proper maintenance (Valve adjustment, compression test, leakdown test, 'shakedown' for issues, etc.).

Once you have some knowledge, you can answer alot of those questions yourself and be prepared for the next step.

Good luck.

 

I'm not sure the S2000 is the most reliable platform for boost. Between the blown head gaskets, broken differentials, piston/ block issues and more. It's an expensive proposition to do it correctly. My inline pro stage one was enough to shred my differential in short order. And I don't launch it at all. That was a $3000 upgrade.

Now dealing with a head gasket problem, and possible ruined cylinder. Plus it's laggy as hell, so it's annoying to drive.

If I were to do it again, I'd do a complete build or purchase a corvette.

Any way you slice it, boost on an s2000 is not a simple or cheap affair when done properly.

And before the claims that low boost or modest increases are "safe", that's simply not true. The s2000 is a highly tuned car and, yes it's rather fragile.

 

S2000 is the perfect platform for boost. Incredibly reliable, motor handles a ton of boost without issues, no need to build engine unless going for crazy power!

Low boost setups are extremely reliable and very safe. No idea what you are talking about..

Only thing fragile is the diff if you don't know how to launch the car or abuse it constantly.

For reliabaility and your goals I would go with a supercharger setup. Either Kraftwerks new kit or the Science of Speed Novi 1200 supercharger kit.

Bolt on both would get above your initial goals.

We are having a group buy sale on the Kraftwerks kits if interested in one of those.

They are bolt on 400+whp kits.


As for reliability with superchargers on this car I have over 65k miles on my sc setup on my S2000 which has 193k miles total on it. Zero issues. Same exact maintenance as stock and I am making 420+whp with it.

As long as you get a good tune a good sc setup will be basically as reliable as stock.

 

I agree with Modiction here. The club is full of FI experiences, and after spending time here and educating yourself, you will understand what the limits actually are, and then what people are willing to push for the sake of performance over reliability.

If you get off on the wrong footing, as in not educated yourself and rely on someone else who is not real experienced in the kit you are utilizing, and doesn’t give you the appropriate tune for it, or if you have some other previous OEM issue with your car or engine that hasn’t surfaced yet, then you can make short order of ANY motor in any car running boost through it. With a sound F20/f22 and drivetrain, a 350-400whp Supercharged set up on a stock car CAN be more than reliable. I’ve experienced both conditions of reliability, and bad luck and limitations with abuse. If your in it for the long haul with this car like some of us, just be prepared to spend more money then if you were to leave the car stock. How you use/drive the car has a sizable impact. The supercharger is the way to go for overall short/long term cost and reliability though.

 

As Moddiction said, a supercharger would be a great way to go. It produces less heat than a turbo and will typically run less PSI, both of which are beneficial for the longevity of the motor.

We sell the Kraftwerks kits as well and always have great pricing on them. You can check out our website to get details on the kit. The Kraftwerks website also has a ton of information on it as well.

As Moddiction and S2000junky said...I couldn't agree more. When PROPERLY set up, tuned and maintained (not to mention driven properly as well) all should be fine. Start sidestepping the clutch and running at the dragstrip all of the time and stuff will surely break (mostly the rear diff). I personally think that the addition of a supercharger is a fantastic addition to an already superb automobile!

 

sorry i honestly dont agree with that statement at all.

 

It's Just fine to disagree, I promise not to be argumentative or to post anything that I know to be inaccurate. I have no S2000 supercharger experience, so I cannot say. And, I would defer to the experts who own, sell and install supercharger systems. However, my IP turbo setup has not been good. I simply wanted to point out the issues I'm dealing with. I did not install or build my setup, it was done at professionally by IP. I've never drag raced my car, I've not launched it even once. 2nd gear gets full throttle though.

A quick note about me: I've been involved with factory and race turbo cars (mostly Ford) for well over 30 years. In the early 1980's I was building 700+ HP 1.7L turbo engines for race teams. I don't claim to be the worlds leading expert on Honda's or any other make. I simply observe what some people do and the mistakes they make. I'm a busy guy, I don't have the time to do a full sleeved engine build on my S2000. Clearly, I believe, it needs it to be reliable.

There have been a good number of "low compression" events. Due to various reasons. Head gaskets come to mind, especially the 3mm head gasket, and of course poor tunes. Even guys with good tunes have lost engines on the dyno. Here is an example of a supercharger install that lasted 2 weeks. https://www.s2ki.com/s2000/topic/107...#entry23075286

Here is an interesting entry from someone who simply gave up on his supercharger setup, "S/c kit is sold to a local, sorry guys. I sold it with specific instructions. Stock motor. 14 pound. Don't bother with a buil motor. LOL."

There are a very large number of documented failures on this forum alone. Another interesting quote " My car has been good as of late.
My car ran fine for the first 22k miles. Driving hard and beating on it taking it to the track. Never launched it tho.
My head gasket blew at 22k I changed it an so far I've put about 4k miles on it. Nowadays I don't beat on it as much as I use to but I still try to make it to the track everytime my friends go"

Another guy: " Quick update: Pulled the motor. Brought it to Laskey to take a look. Looks like my #3 piston is damaged."

I'm not yet convinced the stock engine is reliable with just a bolt on kit and a good tune. The guys above had some of the best tuners.

This is my stock pinion gear, 13,000 miles boosted, 40,000 total miles.



Here is another guy that made it 4000 miles before the rings cracked, Evans tune:

 

In conclusion, I may not have been tactful with my choice of words. However, I believe a properly boosted S2000 is not a cheap project. That was really the point I wanted to make.

Differential: I believe it's a "must do"
Clutch/pressure plate: Also necessary
Fuel pump upgrade: required
