Modified N/A'd S2000's, how much RWKW?

[Steve695]

Hey all.

To my understanding, the s2000 has about 136RWKW stock.

I was just wondering, from those out there who have done engine mods and left your S2K's N/A'd, what sort of power are you making at the wheels?

I want to aim for 155-160 at the rears, but it seems very hard to achieve with the F20C being so highly tuned from the factory, so I'm curious with what other people have achieved and what sort of mods they used?

[ludecrs]

I hit 145 or 150 before going FI with just a toda header, K&N FIPK, and Invidia exhaust.

Not bad at all.

So if I get a decent exhaust, intake and a good ECU/dyno tune I should be able to crack 150?

I'm not allowed Forced Induction because of P-plate laws, pretty silly laws i swear the people who write them know nothing, a standard S2K's will beat a lot of V8's and turbocharged cars.

However, I personally prefer the N/A'd appeal to S2K's anyway, but just want to try and make some more RWKW's.

It's not a matter of what car beats what, it's the power-weight-experience-ratio. In my opinion, it's torque that kills - nothing we have to worry about! :D

That's not what I meant. In Victoria, P-platers aren't allowed to drive turbo/super charged cars or V8's. I was just making a point that it's silly because it's perfectly legal to drive an s2000 (being an N/A'd 4 cyl).

Anyway back on topic.

[zhong]

Ok. Back on topic.

If your looking for that extra power, do what luder did - but keep in mind that it's probably the max you can do for alot of coin for so little improvement, almost just enough coin to go FI. Wait for your fulls, save up then go nuts!

[ludecrs]

Not bad at all.


Forgot to mention that was also with an Invidia Test Pipe.

[**Ghost**]

Ludercrs what'd you tune it with?

[VeYzZii]

Hmmm. Im going in for a tune in about a month. My mods are: Full exhaust from Liverpool Exhaust (extractors catback and mufflers), cold air intake, ported and polished head, and gonna tune it with an Apexi Neo. Oh and its headlight washers are shaved :P What should i be expecting at the wheels?

How exactly do you shave the headlight washers? It is something I want to do.

Let us know what your dyno reading is when you get it done :D

[nigoape1]

i had header,test pipe,muffler,ECU,injen intake and E85 fuel dyno test was around 155 KW at wheel

[dlai5552]

I've seen a car with buddyclub exhaust, injen intake and 5zigen headers make 145kw atw.
and wow! chris, I didnt know you use E85.

but remember, it all depends on the day you get a dyno.. some days better than others depending on weather and how your car is feeling on the day.

[euromandeluxe]

Recently had this done. Unless you're good with panels you need a panel shop to do it for you. They pull the washers and fibreglass the hole up, then respray the bar. Looks much cleaner

[ludecrs]

Ludercrs what'd you tune it with?

I can't remember if I had the AEM 1052U in at that time, but I'm thinking not, as I only installed the ECU, on the day I put the bigger injectors in, which was a week or 2 after I installed the S/c, so I'm 99.8% sure it was on the OEM ecu.

As euroman said it's best off given to pros for things like this. It's not a big job at all, but skills and tools are needed. They would pull them out, then plastic weld over the whole, then bogg and sand down for reapray. I couldn't quote you how much cause I just send it in to a good friend of mine for body issues. And I will definantly post it up here somewhere.. And maybe add a couple of 0s to the end :P

Oh nice, thanks. Yeah I have seen photos it looks great.

Because all I want to do to my s looks wise is lower it and get that neat looking front lip that clips onto the stock one with the headlight washers, and wheels. Also a few small dents that bug the hell out of me that I want to get removed.

[Steve695]

That is very impressive, what sort of ECU did you use and how much do they cost?

[nigoape1]

well i would like to tell all u ppl out there....!dont use E85 it had given me too much hassle....especially looking for petrol station that sells
E85 and bring all these jerry tank to track day and shit....too much hassle....tune for E85 is very important i had been back to the tuner for about 3 time to fix the tune...could be the tuners fault...not skillful enough maybe and in a long run the E85 will eat the fuel hose and injectors so better of stay with 98.
and my car is at the tuner right now tuning it back to use 98....only 4-6kw diff

[nigoape1]

i am using Haltech and it cost me around 2400 for the ECU and ported TB inlet....plus tune

[vyets]

Daym Haltech baller wish I could afford one, who tuned it for u :D

[ludecrs]

Thats what I've been saying.....

The costs for going to E85 is not worth it factoring in bigger injectors and tune etc. Might as well just run race fuel.

[dlai5552]

haltech is so baller.

btw, vyets, which ecu are you running?

[vyets]

stock lol

[nigoape1]

On safe side better use hondata kpro
Less hassle and even a knob can tune it easy.
Altho haltech is good but the tuner is more important whether he know how
To get the most out of it.

[dlai5552]

kpro is baller-spec as well. But it is definitely easier to tune, but I think it requires other parts to fit it though which costs some more $$$

[Steve695]

I hear that the hondata chips are very good.

[dlai5552]

they certainly are!
i used it in my dc5r, and it was amazing!

[nigoape1]

yeah i heard u needa buy some AP2 component to use the Kpro..
Elliott had bought the KPRO so i let u know wht he thinks after u installed and tune...

[Ferrari]

My Kpro will be installed this week. First dyno run for my car and it's mods.

[dtrang]

two s2k ran at the dyno day yesterday did 153.6kw atw with aem cai and hipower hks exhaust.

the other also ran same aem cai but different exhaust and made 156.5kw atw

[dlai5552]

definitely due to the weather being cooler. The weather has some crazy effects on dyno reading, and would you happen to remember the type of exhaust the s2k with 156.5kw had?

[dtrang]

Ask trust-me he should know

[rokkuchan]

Fujitsubo i believe?

[dtrang]

yeah fujitsubo. i just couldnt be bothered finding the thread until i just saw this email pop up lol

[rokkuchan]

the silver one was my former glory. I don't like HKS overall - their stuff are just generic stuff but made in Japan.

[Steve695]

That's Impressive. Do you know if that was that with stock manifolds? I thought the HKS hipower was only a catback?

[nigoape1]

Is aem cai a ecu...???
Where is this tuner?

[euromandeluxe]

AEM CAI = cold air intake.

[nigoape1]

If only cai and exhaust obly than the number is very impressive
But can they pls tell us more about wht mod they have in car other than
The cai and exhaust ...??such as ecu and test pipe and header..?

[dtrang]

i dont know much else just ask in this thread here and feedback to this thread

http://www.ozhonda.com/forum/showthread.php?150423-Dyno-Day-held-by-SAHAU-28th-May

[vyets]

Just find a place with a happy dyno and you'll be able to achieve high numbers with just bolt on mods :P

[dlai5552]

all depends on the day!
I'm sure if you drove your car to a dyno now with the current weather, it would show a better reading.
GO GO GO... dyno for $50 :D

[sae]

My Kpro will be installed this week. First dyno run for my car and it's mods.
any updates on this?

[Ferrari]

Still at mechanics... Kpro is not just plug and play for AP1.

It was weird how you take so long to start on E85 when your car was fully warm up. Need more cranking fuel? Tuner didn't compensate for it?

Kpro FTW :P

[fatboyz39]

At least you get a brand new AP2 rocker cover :P

[Ferrari]

Yep I saw it yesterday installed looks tops!

Can't wait to pick it up today.

[tamay_s2k]

i got 140rwkw stock so i could imagine with a proper intake and exhaust ull have about 150rwkw? not 2 much of a gain but as there already using some quality bolt ons standard
ive HERD *qoute me if im wrong guys* but apparently with a retune u can potentially get an extra 20rwkw.
bee's dick gain though but it would still help the car as its a light focker :P and bolt ons are almost useless unless u wanna shed weight

20kw gain in an NA is Honda is huge, and that's Top end!
you play around with mid range and you can get around 25-30kw gain there as well, and the car will flyyyyy.

[fatboyz39]

20kw is quite a big claim from just a tune. If your changing fuel and tune on ragged edge then a 20kw shown difference.

[brendan1990]

cause you a p plater you will probably ignor this, i did when i first got my s, but the 3-4k you can spend on a decent I/H/E could buy tyres so good you would destroy any I/H/E build by miles. in fact for the price you could fit some BC br coilover's in there to!

[euromandeluxe]

Hahaha, those tyres really had a lasting effect on you hey :P My fronts landed in Aus today!

[dlai5552]

Hahaha, those tyres really had a lasting effect on you hey :P My fronts landed in Aus today!

Are they direzza star specs!!! I just got some as well :)

[brendan1990]

haha you have no idea, swear to god next car coilover's and tyres and im set!!

[VeYzZii]

Ok well here it is! It made a 148kW prior to the Apexi Neo tune. And now its at 156kW. Dynoed and tuned at Toda Racing.

[dlai5552]

is it just me, or does that curve look kinda funny?
maybe it's the scale of the curve. but the top end power is very good.

The graph starts at 4500, maybe thats why. Thanks man. I was happy with it.

[Steve695]

impressive

[Steve695]

Thanks for all the info people.

Sorry for the late reply, I am all for handling.

First mod I did to my S2000 was Buddy Club N+ coilovers and Enkei PF01 17x9 all around on Toyo Proxe 4's :thumbsup:

[greek_rambos2k]

i have a hks hi flow cat back, makes quite a good noise and i did notice a small power gain from stock

[greek_rambos2k]

how are you finding the starspecs? im running ad08s on my s2k, but i placed an order for starspecs with tirerack for my mr2 gts.
