All Motor

[ugadogs_11]

Hello I am wandering what you should do to get great performance withot forced induction. I do not want to get a turbo or supercharger right now, so I am wandering what performance upgrades i should get if I want to run on all motor.

Also, what exhaust should you get if you have an 07'. I like many exhaust systems, but none of them seem to flow well with the rear fascia.

Aaay Uga, owyadoon?
As bolt-ons'll only net ya a max of somewhere in the vicinity of 12 HP r' so, I see no other option than our ol' faithful friend bore n' stroke. Theres outfits out there that have some done-up engines in various denominations that you can buy outright, r', if you're the do-it-yourself type (don't attempt this at home if you ain't got the experience kiddies) you can roll your own.
'Don't see no alternatives once ya rule out forced induction.
I'm also not familiar with jus' how much meat's on li'l Stewie's bones, so I'm not sure jus' how far you could go in this direction. We've got nice folks that'll provide that info, I'm sure.
N' 'zaust systems come under the headin'a bolt-ons n' I'm still runnin' stock so I'm not the fella to talk to. Someone'll be along shortly that're well-versed in 'zaust.
Be well.

If you want to stay all motor, you will spend a lot of money and **might** see 225 WHP, but that is VERY rare. You can spend even more money and see 250, but by then, you have spent as much as going with boost and still will have less then a boosted S.

As for the exhaust question, it's a personal preference.

What brands to you recomend?

I love my Comptech, but I have an AP1.

I also have Comptech (both CAI and exhaust). Dyno'ed at 223 rwhp and 160lb/ft of torque. YMMV (and dyno readings are like statistics). I've seen stroked 2700cc engines and 2500cc turbo'd engines...both make lots of HP but you give up reliability for more power. A trade off you have to decide is worth the effort.

Thanks guys. I really love the Greddy SP2 system, but they do not make it for the S2000. i was wandering if I would be able to get the tips of the SP2 and put them on the EVO 2. Do you guys think that would work? Do they even sell the tips?

I dont think they sell just the tips. maybe the whole muffler, i know skunk 2 does that not 2 sure about the Greddy SP2. As for me i ended up goin with a whole Invidia 70mm Ti tips and test pipe. that i got off a guy on here with the CEL fix throwed in. I love the system. ANd if i ever get the loot to super charge 70mm should be plenty big.
