200hp on N/A engine?
 

So if a bone stock 99 1.8liter makes 140hp at the flywheel...is it possible to make 200 or a little over by redoing the head and putting in high comp pistons? I need to pull my engine cause I have a whole bunch of stuff that needs to be done, and I thought, "I wonder if I could sell all my turbo stuff off and build the motor up...and if I do, how much power could I make?"
I was thinking, I could use my MS of course, keep the 460's in there...use 11:1 pistons, get my head totally re-done, run 93 octane, put a header on it, etc. I assume a turbo setup on a stock motor is cheaper, I was just kicking around ideas.

no







































but you can make about 250 n/a :giggle:

Do you have $10k?

if the answer is yes, my answer is yes.
if no; no.

Alright...simple question, and a simple answer...thanks guys.

No.

I imagine you could...if you also spend to get it to rev a little higher. I don't think the powerband would be desireable (think sportbike)...where a turbo'd car would be much better (think "area under the torque curve").

If you got an N/A BP motor to 200hp it would have a gay amount of torque compared to a turbo car at 200hp.

Really?

I just thought it would be a peaky little bitch like a Honda.

In that case it might be worth it, and would probably make for a very nice package in a Miata.

I can't imagine it being cheap at all though.

With enough money anything is possiable :)

Seeing as some make 170whp, thats at least 200@crank, although terribly retarded unless you're limited in your class.

waaaaayyyyyy too expensive, but possible

these EVOs make around the same Horsepower as the S2000:

but take a look at the torque:

wanna take a guess which one is the utmost monster out there? Please show me a peaky honda graph please.

wow, thanks for the lesson

s2000
250Nm = 185ftlbs = GAY

Yes you could make it pretty easily if you know what you are doing, probably on mostly stock components, everything but cams and pistons.

If that was the case, don't you think that a "few" of the hundreds of thousands of Miatas built would be sporting this? And to think, I spent all that money turbocharging my Miata when all I had to do is change pistons and cams for the same end result.

Well the only problem with it would be detonation, so if you were going to make 200N/A just throw a set of 12:1 in there with a E85 tune then port the head and make sure to flowbench it, that is the key and have some cams made up, pretty sure that will make around 200 no problem. key is matching up cams to head flow. And most people dont do that b/c when doing this you loose all ability to go further than 200 with any components, forced induction gives you room to go up in hp. So if you are just wanting some peppy DD and nothing more na will be fine, but for all you race car drivers you want 300 or whatever you are making you go forced induction for room to upgrade.

vs. what a turbo ~250rwhp BP motor makes(on a crappy tune)

And how much money does that engine cost?

I'm so doing this, like tomorrow.
