Hey guys this is my first post, and first time on the site, but i just bought a 2003 S2000 in Sebring silver, and i plan on building it up all motor, but want to start with the suspension i was hoping for advice on everything from what coil's to get to the best roll cage for a s2k. Any little tips or tricks are also welcome im tryin to learn all i can about these things thanks guys.

 

Well first and foremost...WELCOME!

Its a beautiful and well built machine that you itch to drive everyday. Its just that great!
What are your plans for the car? With that in hand, I would be able to add my input accordingly.

 

honestly its going to be just like my last car, i had a track built wrx as my daily driver and i plan to do the same with my S2K. im going to go in the same order as i did with the subaru (suspension, weight, then engine and transmission), it already has spoon sports monoblock front calipers, spoon sports ram intake, spoon sports cross brace, and spoon sports strut brace from the previous owner. he also threw on 16" authentic Spoon Sw388 wheels, the greddy front lip, and JDM lights all the way around. thats all i know about it for now i pick it up this weekend if theres more i'll let you know, but first thing i wanted to put on was a set of coilovers and i was wondering what everyone was throwin on there S's, i personally am a fan of Stance's coilovers but havent found anything about them on here, and then i was going to put on the cusco 4point roll cage with harness bar, and my Corbeau lg1 seats.

 

roll cage on the street is never a good idea and cusco doesnt count. A roll cage shouldnt have bends like that. Im not saying it wouldnt help if you rolled over. If you HAVE to get a cage look into the hard dog.

 

you want advice about all motor... its a waste of money... go FI if you want power... if not I/H/E and gears def make the car alive... but itll prolly cost you around 2 grand...

 

btw cusco/safety21 r not fia approved so if ur planin to do anything more than auto-x or hpde they wont let u compete.

 

This sounds a lot like this car here.

Are you in Colorado, if so you should problably give up on the all motor dream unless you want to spend more than FI to get an additional 60hp if you're lucky. The high altitude is already hard enough for NA cars to overcome, add the fact that the S is pretty maxed out from Honda as it is. If you really want all motor you can start with K-Pro for a quick retune, header and intake with another retune, finally cams and ITBs and another retune. Second option do a K swap as the K series has better gains in NA mods then the F engine does. But that is going to cost money too, also so far to my knowledge only one guy has pulled it off.

As for the roll bar if you get the cusco sell me your hard top as you don't want to cover up all of that baller blue.

 

compete in what the 24 hours of lemans ? cages are judged and certified based on rules requirements for each series, safety 21 has products for many.

as far as all motor it depends on your budget - start with the aem v2 intake and get a nice exhaust - the next step up is a header and tuning so you may want to spend the money stripping down weight ect first as it's a big 3K step for a hytech header and ems with tuning.

 

The cage has illegal bends from what Ive heard.

What would you trust?


hard dog. This is legal for the track.


hard dog. This is also legal for the track. I think gt motoring has this one in red and white S2000. not 100% sure. notice how it still has the stock seat belts.

http://image.hondatuningmagazine.com..._roll_cage.jpg This is just mad JDM. look at all those crazy bends. you will hit your head on that for sure!


cusco roll bar.

Here is the Safty 21 after a crash. This is quated from a memeber on S2ki.

 

Whatever world you are living in, I would like to be a part of it...

Gears and install alone will run you about that alone, not to mention, a good quality intake, header and exhaust will put you close to what you would spend going to the darkside.

 

I would have "liked" the all motor being a waste of money comment if this was facebook. The dark side? Going turbo on a S2000 buying new parts with discounted prices runs you about 5,500-6,000 giving you mayabe 80-250 extra horse depending on what you buy. Then you need to figure out install and tune. A good intake and exhaust will give you maybe 30-40 more horse with a tune at best. I know the gears will help but I would think that would make high way driving a pain in the ***. FI wouldnt sacrifice any of that.

 

I love the fact that Im in the darkside myself...Even though I have the want and need for more power, I wouldnt change it for the world. I respect both FI and NA cars, but Ive always been a fan of having a snail underneath my hood lol

 

To the OP, if you really want to make some good power and have good response, I will be putting up my Greddy kit for sale soon. Its reliable and very very fun for the street.

 

you don't just bolt on 250 extra horse - you bolt on competent tires, suspension, clutch, loss of gas mileage, loss of street tractability ect ect ect.

All motor can if done properly be fun for a daily you can really use all the time - if you really want big power the rotrex supercharger kit is your best option. If you want retarded should of just bought a v8 solid axle levels of power there is turbos for that too.

As far as gears go there certainly fun but your going to average 600rpm more on the fwy in 6th with 4.7's which doesn't really bother most people that much - there's also 4.4's - the gears themselves are 300 and up and you can find install hookups that may do them for another 300 and up.

I can tell you this - I've seen what a fully built all motor s2000 can do - it can crush world challenge spec vipers on the high speed banks of cali speedway and zip through any corner faster than most anything else.

As for stance stuff thats KW v1 and 2 almost v3 money I suggest that instead.

I run Koni Sports with eibach pro kits and GC top hats and they work perfect - the faster autox s2000 are using the gc coilovers

 

I bolted on a extra 100 and had stock suspension, stock clutch and the stock tires... I guess I was doing it wrong? I went from bone stock to FI. I also had better MPG with the turbo. I have a new set up in the works and with a better tune and longer final drive, I should be getting +25 MPG. I know all of this from first hand experience. Doing it the wrong way and doing it the right way. How do you know what you know?

Side note. Inline pro ran 9s with stock suspension

 

i think im living in the same world as you... but if youd like to join ill consider...

first of all i didnt say new parts... you have to shop around and wait for good deals... these are the prices that I personally paid:

4.77's with yellow jacket - $300 plus my AP2 pumpkin
Injen intake - $250 new
T1R 63mm single - $300 used
berk HFC - $100 used
berk header - $500 new

do the math... seems to me that it adds up way under 2 grand... I understand that I got a crackhead price on the gears hence why I boosted up the price a bit... but theres no reason why you couldnt get similar products for those prices... and the best part is that all of my parts are top of the line quality ****... also, theres no reason that a weekend mechanic couldnt install everything listed above including the diff... grab a friend and a 12 pack and your set...

 

My advice is to buy a car that already makes power. S2000 is a headache, especially if you do it wrong.

 

^^ if you're chasing power, this is true

 

should just get a civic, its God's chariot

 

y'all need corvettes

 

Very true. Actually, stock suspension is the best and cheapest suspension choice in order to catch traction at the track.

I too have better gas mileage now than I had when it was stock.

 

Do you know what s2000 drivers usually mod first??? Its actually tires. NA or FI, you need traction.

You will spend the money on the bold things mentioned above whichever way you go, so dont make it seem like its a deciding factor in going NA over FI.
It has been proven time and time again the FI is the most cost effective way of reaching any decent amount of power.

As for your built all motor s2000 statement bolded above, I call bs on that too. And you think that a fully built all motor s2000 wont eat more gas than a turbo one???
To give you a real life example. My friend has a k24a ep3 with cams/intake/header/exhaust/kpro and he pays more visits to the gas station than i do in my turbo S.

 

If the OP is really set on an NA build, then a good intake, free flowing header, test pipe and exhaust along with some 4.77 gears will be perfect for him. If you have the need for a bit more power then I would suggest some cams and aem ems to get the best of it all.

 

to give me an example of what - you have no idea of what your talking about.... because your friends POS craptastic hatch runs crappy you know what your talking about ? lol

Most likely he goes to the gas station more because he races his hatch around on the secondary cam more - hardly scientific

and when did 250 like I said become the same as 100 ? the math says you fail and even the fact you decided to bolt a turbo kit to go fast in a straight line does not impress me and tires are not part of any turbo kit I can recall.

BTW it's simple math if a turbo equipped car is required to run 10:1 afr on boost and a all motor car can be tuned to 13:1 or better all the time. The only way it's possible for a turbo car to get better mileage is to not actually use the turbo....

when have you ever personally "fully built" anything for the street or otherwise ?

BTW that car I referenced was Dave Karners Honda Cup race car, you don't have to take my word for it the owner of s2ki will tell you, Derek from Hondata will tell you, john @ hytech who built that motor will tell you. Shaun Church at CAT who tuned his and all of the other dominant s2000's running in that series and many others will tell you.

If you really want to go boos there is alot of cheap used kits people are selling and going back to all motor....must be because it's so awesome they want other people to experience it

 

Well first off, you dont know how he drives the car, so stop assuming. He drives like a regular human being, and it requires for him to fill up more often than i do. Not to mention, its called calculating gas mileage, we both have done it, and yes mine is more efficient when it comes to consuming gas. YOU CAN THANK JEFF EVANS FOR THAT. Its all in the tune.

My AFRs are very very conservative. If you knew ANYTHING about how Jeff tunes, you know he tunes very very conservative. They are pined at 11.2 at WOT.

As i recall, yes tires are not part of a turbo kit, but they are not a part of an all motor build either. You will STILL need better tires for an All motor build, not to mention HEADWORK. We dont need headwork on a boosted car to make over 500whp or even 600whp, or even 700whp, and you should know that if you did your research.

Take a look at my signature, you can see that I have had fully built motors quite a few times, so I am very familiar with them. No need to criticize or assume anything about me.

You apparently dont know dick about anything, pardon my french.
