Hey guys i have been doing some reading between ITBs, SC and a turbo kit and i really cant decide. Anyone help? roughly what would each kit cost and powergains?
Turbo will yield most gains then sc last is itb.
So essentially what we are doing here is comparing potatoes, oranges and strawberries, and which one is the best.
Ie, its pointless. They're all different, achieve different things for different purposes.
y not get the ITB and use them with the turbo or SC
ITB's are just the throttle body, just individual for each cylinder stack.
^^^ what he said
You mean NA v SC v Turbo no?
NA would mean mods like ITBs, Stroker Kit, Cams, etc
basicaly i want to spend 4ish grand on a power upgrade. i was looking at first looking at toda ITBs then the greddy turbo kit and comptech supercharger and i really cant pick between. i use my s2k as a daily so i want power gains that can still be used in daily traffic and i have about 4grand ish to spend... can go a little more if i have to tho
IF you go FI, there'd be alot of problems with S2k driveshafts with big power. All over the net. People get stronger aftermarket ones. I cant tell you what cause I dont really know but the info is there.
If you run like 8 psi you should be fine though. Maybe less. F20C are highly tuned from the factory with hi comp pistons, with FI you need low comp.
Also when you consider your upgrade, consider othe necessary upgrades to such as a HD clutch, ECU and tune. Installing a supercharger,turbo is simple as 'slapping' it on.
As I hear alot of tools say.
Think about how much power you want. Can your gb realistically handle that power? You may need to factor in a gearbox rebuilt with stronger parts.
-You will need good tyres to get that power on the ground.
-BRAKES, no point in going fast if you write yourself off in the first corner.
^^ LOL ericl33
Really stupid question to be honest. And 4k? you'd need to set your budget higher than that. Take note what DakDak posted before. And btw hows your rear diff? S2k rear diffs are known to be weak. Should set money aside for when it does blow. Also check your engine mounts.
First tell us what engine mods you have done to your s2k?
What I would do is go with turbo or supercharged. Get the kit, get an aftermarket ecu and get it tuned. You can run low boost on stock motor usually around 7-9psi? or something
Also depends on how good the tune is. Otherwise you'd be coming back to the tuner non stop regarding problems etc.
which conversion is cheaper, turbo or sc? i would prefer a sc as i like smooth power over the turbo kicking in... if that makes sence. lol yeh i can spend more then 4 i just have 4 atm... lol. What would the build cost? my car mods so far include: "performance wise"
K&N replacement filter
cooling plate
HKS hi flow catback
hi flow cat 100cel (havent installed it yet tho)
eibach springs
js heat shield
torque damper
oz alegeritta rims 17x7.5 (225 tyre) and 17x8.5 (255 tyre)
yokohama ad08s
ds2500 brake pads
Yeah i know s2k difs arnt great. Mine is fine though atm. makes a little tiny bit of a noise but LSD works fine. I dont do burnouts or anything
I dont know much about turbo/supercharging f20c motors. If you're really serious maybe have a talk with some workshops that have done the work before, or other s2k owners who have done it. Look at some build threads and have a read through on what they have done.
Easiest way to achieve that 300hp is turbocharging. As for what kit is cheaper, gotta have a look around.
For that smooth power delivery a turbo kit would work great depending on what turbo you're running and how its tuned, you may have full boost kick in as early as 3-4k rpm for a more linear power curve. Same as a supercharger kit. I guess it all comes down to your decision, turbo or supercharged.
You can get a full turbo kit for like $7k+
but remember, you have to get it tuned as well, and also as someone mentioned before strong diff.
Why are you looking at more power anyways? What's your purpose?
In your case - the best option in my opinion is the S/C option.
Supercharging your vehicle can be done in your own garage over a weekend - most kits are BOLT ON. You will not NEED to think much about adding sophisticated fuel management, as most super charger kits come with RRFPR. These kits can be bought from the states for around 2-2.5k not incl. shipping give or take quality and completeness of the kit. Well when I was looking at this route anyway.
It'll be more suited to daily driving as it doesn't stress your motor too much if your on a 5psi pulley and you won't be breaking axles on a daily basis!
Oh, and you don't need to modify anything in the bay - so you can return it to stock if you decide to sell the kit for a turbo kit couple months later. :P
Peace.
save more money
420whp.
Stock diff.
Stock axles.
Stock clutch.
No issues.
I really dont understand why people are so negative to FI.. been boosted for over a year at around 250rkw, stock everything apart from clutch and my car takes a beating day in day out.
get a base SC kit if you want to make around 290-300whp.. can be done for 4-5k if you do the install yourself..
you shouldn't break a thing at that power level..
From what I have read the standard f20c can handle 14 psi... Done a bit of reading on s2ki and ppl are putting down over 400 hp atw... This would be insane to drive over stock :)
Check out the mase turbo kit for some inspiration !
Strengthening your drivetrain would be costly, like ludecrs said he was running stock gear and held up fine... If you upgrade what you think might break budget for 20k lol... Just repair as you go.
Turbo itttt
smug self-satisfaction of owning and driving a 300 rwkw convertibleQuote:

The most common problem in Australia with our cars is that noone really knows how to tune them [oh and haltech costs an arm and a leg]. The same goes for basic n/a mods and FI tuning.
But yeah, out of all three ITB's seem so gangster. Not the best with Australia's weather; hot and cold every second day but if you go through with it i'm sure it'd have merits of its own.
Definitely +1 for being unique
Sell your s and get an Evo.
Turbo a d15
the only thing wrong with this thread is the 4k budget.
would you get much gains from an e85 conversion? (keeping it NA)
Yes.
Gains are normally 15-20kw more than your normal 98ron.
This will also depend on your supporting mods and tune.
Selected caltex supplies these but during winter they mix the ethanol blend to suit the winter season. (less ethanol ron)
Something to think about
I think I know what graph ur.talking abput. There are mid range gains of.about.20kw but peak was only about 5 ish.
If you're sticking NA you won't get much out of your ITB's without atleast all other supporting bolt ons and preferably some head work done as a starter.
You'll need an airbox made up for them to or be destroyed by the first cop to look under the bonnet. Also good idea to have as you can run your ITB's but still have a single big filter for all the air to come through, do not run them unfiltered or you'll **** your shit eventually.
Also you will need an aftermarket computer to run them.
Ethanol has lower calorific content than petrol so that's a negative. On the positive side it has a higher octane (resistance to pre-ignition) so you can run more timing and compression. But compression is a physical change to the engine so requires a rebuild and I don't see how timing alone with give you gains over petrol.
So if you want NA ethanol be prepared for some engine work. At least shaving the head.
BTW, when you read through this thread weight posters opinions by what level of experience they have personally had. I note one poster suggested a turbo will kill your gearbox, diff and driveshafts yet drives a DC5 type R. Not saying he hasn't built an FI S2000 but still...
FI doesn't kill your gearbox, diff or driveshafts, stupidity kills them. FI just gives you the tools to do it quicker. Ask me how I know?
This is good info...
Timing alone can gain power IF the engine combo has been running retarded timing due to using fuel with a low octane rating. Although if this is the case someone has wasted their time...
E85 can provide good gains on N/A motors, however they need to be high comp ratio (higher than stock Honda comp) to see the gains.
F/I motors work so well on E85 due to their Effective compression. An example is my turbo falcon, normal comp is 8.8:1 but with 19psi peak boost it is running 20.2:1 comp.

With 4K you wont get a hell of a lot.... basic power upgrades.. every change has a knock on effect as already mentioned by Dakbak.
Read as many forums as you can, learn from these, look at other engine builds ask more questions. Sort out the bull shit from the facts.
Some guys love turbo some are more purist and love the high reving all motor builds as I do. I have driven them all, from Porsche GT2's GT3, Honda S2000 turbo with 420whp to All motor race engines of every make. Each gives you a different sensation when driving hard.
Take your time to decide and do it once dont cut corners and do things on the cheap because it will end up costing you way more...
noooo dont talk about diffs. mine is making noises :( but it has been for a yr and my LSD still works so meh
If I were you I'd pick up jowjeh's dud diff and have it sorted before yours blows.

If you want to make 300hp, put nos on it
Greddy turbo kit. DIY install. $4k w/pre tuned ecu.
hmmm im thinking of going for the greddy kit. i do like it
Maybe have a good thorough read of this if you still want to go with the Greddy kit, not to mention the # of greddy kit owners that do change onto more expensive & powerful kits out there. I hate to sound like one of those ppl who talk crap coz I don't own one, but I have been doing extensive research on kits, particularly on RHD ones, and have come down to two. Anyways, each to their own, here's some reading that should put u to sleep :)
http://www.s2ki.com/s2000/topic/6479...bo-kit-thread/
thanks for the link s2kjn, interesting read..
So u still gna go for the Greddy kit?
yeah i think i might...
SC ftw
Check out Steve from msc performance turbo built s2000.
When I was at his shop the other day he just finished supercharging a s2.
Best guy to speak too
Tuned my car also and did a great job
Yeah, what could be better than talking to a guy who has built both an SC'd and turbocharged S2000!
Lol.
Nar is all seriousness speak to Steve.
He will show u the cars and the setups and give u the best info in regards to making ur choice.
Information is power
yeah after reading that 4grand wont get me far ill just put more money in. it will just take me longer to get there lol
Stop wasting it on wings and valve covers. ;)
^hahahhahah.
Ooo, them's fighting words!
lmao iv always wanted a wing though. its cool i dont mind spending more it just means i cant do it within the next 3 months lol ill do it end of the year instead.
^grow up, lets keep on topic
hurry up Simmoyo I want to see your numbers :)
