Hey all,
Just browsing the forums. I noticed most people quoting s2ks doing a 13.9 quarter.
I've also read somewhere that stock s2ks are faster over the quarter mile then stock s15s which do a flat 15.
Is this dependent on the gas they use? or do they race 0 - 400 downhilll.
How much mods would it take to get an s2k into the low 13 braket?

S15 has been clocked by a local mag at 14.59sec over 400m.
Though, if you launch the S2000 'properly' then it will be quicker. Bellow 100kph there's very little between the 2 cars, but over 100kph the S2000 is quicker. I have a friend with an S15 ... which was 100% stock until a few months ago. I've done some thorough 'comparisions' between the S2000 and S15 so that's what I base these comments on.
ps. In US they use a different timing method to us here. They use 'roll outs' and such while local mags do not. Though, the local drag-strips do have a 30cm roll-out which can be taken advantage of.

Really just what Auss2000 said. There are no N/A mods to make the car noticably quicker. Well, except for gutting it and making it a lot lighter. Though, it does not seem that you can get more than 10kW exytra out of the engine without FI.

ure telling me u cant get an NA s2000 in the 13 sec range?!? Only an extra 10kw out of the engine?!? WTF. Ive seen it done in a dc2r, y couldnt it happen in an s2000. We'll see soon, hopefully by Nov i should be done, tunned and ready to go. And if my experience is going to be dismissed as hearsay, have a look at Hot version, Battles @ 10K RPM. Stock 01 and 04 vs street tune MCR s2k. The MCR clearly has much better acceleration with basic NA Mods. And yes I understand FI will give u power figures NA cant, but dont rubbish NA all together.I mean telling this guys his not gonna get more than 10 extra engine KWs with NA mods thats just BS.

See theres the difference, im not here to prove anything. By tuned i meant ECU to accompany other mods, is that so terrible. Im well aware FI will get me much more power, but Ive chosen to go NA, just like others have chosen to go FI. Difference is I respect others choices and reasons they've made them. Everytime NA comes up its like "Hey moron go FI,other wise uve got no clue,so dont post" I dont think i need to prove u can gain more than 10 engine Kw with NA. Im just fed up of NA bashing. Personally i wouldnt go FI, i would have bought an FD instead, but do u see me trying to ram that down the throat of others with different opinions.

i think what they are trying to get at is cost over benefit. u spend x amount on NA and then x amount on FI and the gains from NA tuning wont be all that great. dc2Rs are different because they respond better to NA mods then the F20C does. It's already quite tuned from the factory.
But i will be watching closely to see how much more u can get out of it with NA mods.

Give it a go and see how you go. With an incredible 60' time almost anything's possible (for any car), but I'll be interested to hear what times you get. Over the last 5 years I'm not sure if anyone has beaten 14.5sec localy.
Only an extra 10kw out of the engine?!? WTF. Ive seen it done in a dc2r, y couldnt it happen in an s2000.
Simple. Both are 2L, one 151kW, the other 176kW. It standsa to reason that the engine with less power can be 'tweeked' more. It's only logical that the IT-R engine one could get ~25kW to get it to S2000 level. Considering that there is no other (road going) engine in the world that extracts more power per liter, what makes you think that you can do better?
If you get more than 10kW extra out of the S2000 N/A, then you're doing better than Mugen or Amuse (who both claim ~5kW gains). The local race team that run an S2000 in GT-P (ie. production racing), run the S2000 with Motec, no muffler, no catalic converted, and a straight through exhaust as well as intake mods (and not sure what other bits and bobs in the engine). Total gain was less than 20kW, and 1/2 of that was due to not running the catalic converter.
Feel free to try and do better, but you'll be the 1st.
The MCR clearly has much better acceleration with basic NA Mods.
What makes you think that MRC had better acceleration? What you saw was better corner speed, and also better exit speed due to the tyres. Also what is the difference in weight between the 2 cars?
