Was wondering if anyone tried NOS on their S and what the results where.

I'm trying to decide between Turbo or SC to install in a few months although reading through the forums it seems turbo is the way to go. Less stress on the engine and more upgradable than SC while being more effective in the lower RPM band.

As I understand it I can have 7.5PSI without needing any mods done on my engine and that would put me over 300 hp at the wheels.

Anyone in the UK have experience installing a turbo in an S2K I should know about?

 

You must have been reading a different forum to me - turbos are more efficient but dump more heat into the engine, which is a bad thing. They are also more complex (requiring downpipes etc) and it seems that often the issues the turbo owning S2000 drivers are linked to failing manifolds etc.

 

Be very sure you know what you're getting yourself into before you embark on this route.

There's only one person who posts here whom I'm aware has tried turbo-ing his car, Andy Doherty. He ended up spending thousands and thousands on it and eventually gave up and sold it, after he wasn't able to get it mapped properly.

There's a lot more experience and expertise on the other side of the Pond so it's more of an option over there. Over here, you have very limited choices - unless I was able to find someone I trusted to do it, and who had preferably done an S2000 before, I'd stick to SC-ing if intent on going down the forced induction route.

 

Dont think so. You only get heat problems if you set your PSI too high, 7.5 is not enough for a blow back.

I know lawyer thats why I'm asking if there is a place in the UK that has a good record on it. I'm not going to risk it if I cant get it done properly. But having been in both turbo and SC'd cars I think I'd rather spend my money on a turbo instead, definatly more bang for

 

As I understand it, is there a problem with Turbo-ing RHD models, something to do with the steering rack getting in the way?

 

Turbo's will give better results, but there are a few issues and these are the reasons I didn't go turbo.

Custom - not something you can just hookup over a weekend yourself. Usually require quite a bit of tweaking. The SC is a doddle to fit.

Manifolds - loads of problems on a RHD car due to the steering rack being in the way.

Heat - a turbo under the bonnet will cook a lot of the wiring etc.

Tuners - Not many UK, F20C experts. Even less who know about boosting one.

Then I'd not owned a SC'ed car before, I wanted to DIY the fitting (I like to know how and why stuff goes where it does) and 300@ wheels was my goal. I could get that easy on an SC.

 

Hmm my only concern is that SC isnt very upgradable and your spending close to turbo money.

What can I expect from a Comptech SC for

 

Eagerly awaiting a 'my baby blew up thread"

 

NOS is a company .. NO2, Nitrous Oxide, is the gas. (people with it get rather shirty, as "NAAAWWS" is a bit fast and furious).

The SC is upgradable. For $150 you get a new pulley and belt and then get a re-map.

If you want uber power, you'll still need to lower the CR etc.

For 3k look at Mikey's setup, that is stock. On the stock ECU. You'll never get a turbo to run on a stock ECU without serious piggyback.

So if you are going aftermarket ECU with an SC, why not get a 11psi pulley like Si and Mark did, for over 350 @ wheels.

Give yourself a goal, and workout how to get there.
Maybe get a lift in a blown S2000 and see how you feel?

 

...and he still hasn't had the alignment done. Far more important than mucking about with FI.
