I was just messin' with you. I know exactly what you mean.




Correct me if I'm wrong, but it looks like you typed the first half of your response before you read my entire post...

 

Try the Toda 2.2 NA stroker kit in addition to the comments above.

 

I must admit I calculated wrong on the headwork, it should have been $1000.
But that should be enough, for a NA setup the head is less important than for FI, so you really don't need any extreme headwork done, atleast not in this case.
This comes from a friend of mine who have been working with heads for almost 20 years now, and he's very good at it, made the head for the Pikes Peak Saab for example.
I also put the cost for only one cam, and that won't work very well...

Concerning labour and exhaust costs, that apply to most FI installs too, so I didn't bother mentioning that at all since I just compared the costs for the parts that differ. (even though I did add the EMS cost... hmm...)

I'm not sure how many hp a supercharger adds without an aftercooler but that's like a $1000 more.

Headwork $1000, Manifoldwork $400, Cams $1100, Valves $400, AEM EMS $1000 - Total $3900

Still $2000 cheaper than a supercharger kit, with some reservations for some additional parts since it always gets more expensive than you think.

And I'm very aware of the fact that NA is way more expensive than FI, I'm building an NA engine myself.
But for the stuff he wants to do, it's the cheaper choice. Not by very much though, and not calculated on $/hp...
And he probably won't reach his goal either...

The TODA stroker kit isn't an option in this case since that's another $4300 just for the parts...
And you'll have to wait for it for months and months, I know... took me five months to get mine...

 

thanks for the response guys, it's kinda hard to choose between FI and NA because of the supercharger availability. Supercharger kinda doenst 'exist' in my country

I'm willing to SC my F20c until I find some foreign dealers that can offer good deals.

 

I don't understand you argument. How are you answering his initial question? Are you saying that will get you 300hp at the crank? If you are not saying that then what is the point you are trying to make? It's obvious that NA is going to cost more $/hp then FI. There is no contest. To get 300hp at the crank NA you are going to need a lot more work then what you listed. A LOT MORE!

 

I would say add a lightweight flywheel and carbon driveshaft into it as well...as that'll free up some of the power thats already there

Making it easier, cause your already closer to your goal..once I go to a dyno, I'll let you guys know how much my flywheel free'd up...probably not too much but I noticed the difference in the butt dyno.

 

I thought the J's racing AP1 had 300hp at the crank. If so, just do what they did.


But I could have been lied to...

 

I've never seen a dyno of a NA 300hp S2000. Even if you could pull it off and it's the same price or less, you'd still be looking at being 40hp down on a SC car. And no doubt you'll still have to order parts that will have to clear customs.

If I was you, xda, I'd consider going the superlight route--if you can pare 300-400 lbs off your car (it's tough), you're going to at least get close to the same hp:weight ratio that you'd have with 300 hp--and you'd still be NA. Of course, you're going to have to say goodbye to what little creature comforts the S2000 has.

 

And I don't understand your argument...

Did you read the whole thread?

port the head, port the manifold, get a bigger cam and upgrade the valvetrain for a slightly higher redline (9300 or so).
Then, get a AEM engine management system to work it all.
I doubt you'll need an intake or header as the stock ones are excellent; a single exhaust may help.
With all that, 300 is possible. you may need a fuel pump and injectors...maybe.

To which Nobody replied:
FI will get you 300 at the wheels and is reliable as all hell. Why spend 3x the $$$ for a what would most likely become a fragile and underpowered machine?

Because of this I made an estimate on the cost for the stuff Steven suggested and compared it to a SC setup.
I didn't claim this would make 300hp at the crank, again Steven suggested this might be enough.

So the answer might be that I didn't answer his initial question, but I think it's a valid point to set up some guidelines regarding the costs for both setups.

 

AEM EMS for $1K? Pls tell me where you shop.

And an SC kit can be had for $3900...NEW. Many on this board have purchased them for less.

Also, xda, you should talk to Dubai, AMK and some of the others in the Middle East region who are running FI, and ask them how they got their kits. Clearly, it can be done. Assuming you want to go that route...
