I am very happy with the dyno plot that I posted earlier in the thread. Right now I am building a motor because I know it will go eventually once I start tracking the car. I rather get it done beforehand.

As for Begi and the EO number. Give them a call and talk to them about it. If you are planning on buying a new turbo I would highly recommend going with the 2560. If you want to save some money go with the SR20 turbo.

Take my comments with a grain of salt because I belong to this group and get used to the power quickly. However my pocketbook has me in check and I've been down this road enough times to know when to "hold 'em" and enjoy what you have vs what you want. Rebuilding engines until midnight every night during the week so you can go back to work the next morning is not my idea of fun anymore.

Same here. I'm getting to the point where I'll want to mess with the car/tune it or mod it about once a month or once every few months. Can't be in the garage every waking moment that's not at work wrenching on this ****.

Not that I would know from personal experience... but I would certainly build it in a way that it would be cheaply upgradeable for more power down the road. My initial goal was ~200-225whp but I ended up at 100... I don't think I would have been happy at 200 for very long, and would have likely ended up shooting for 250-300. So in short, don't limit yourself in power with the expensive parts. Spend a little more the first time and have plenty of room to upgrade in the future when you decide you are bored with a set level.

I've been happy with 200-240rwhp for the last 4 years. building a motor can be somewhat expensive and time consuming. Not everyone's situation is the same. If I had my own garage and a more enjoyable DD, I'd probably have kept the car in a configuration pushing dedicated track car. But I enjoy driving the miata as a daily, and the more I did to prep the thing for an occasion track day, the less I enjoyed the compromises I had to take.

Even if I had a built 2.0 stroker, the rest of my setup is weak and would just lead to more pointless upgrades and dumping in more cash to make the car less streetable and enjoyable to drive around town and pwn noobs with.

a 200rwhp miata is plenty of fun and figuring out the way to achieve the best overall torque curve can be half the fun. But I rarely drive the thing where I need more than my little stock 1.6L can output.

I'm very happy with my 200rwhp Miata (so far). In fact, I have a GT2560R sitting on the shelf waiting for a CHRA to be installed. I may have to fab a new turbo to FMIC pipe, but otherwise my setup is ready for it. Still, I'm in no hurry. 200rwhp is a LOT of fun in a daily driver. I too drive my car everyday to and from work. Without another vehicle at the moment, I'm just enjoying driving it rather than wrenching on it several nights a week or all weekend. I think the SR20 T25 is a great starter turbo as they are cheap ($40 for mine), easy to find, and outline interchangeable with the more expensive GT2560R when you are ready to upgrade. It will also get you within 40whp of the bigger turbo.

Really? A 500 hp C6 Z06?

I need to lose 200lb in my car. I'm going to keep the soft top, radio, carpet, and heater so I can still enjoy things like...driving my car to Austin for the weekend, tracking it on saturday, then dicking around the rest of the time in town. I keep telling myself that its a Ferrari substitute and not a racecar.

When you get to the point where the available/upgradeable power is not fun anymore, you are at the point where breaking **** is even less fun.

And then you swap.

Start lower and reliable. Enjoy. Bump up the boost, iron out the bugs, improve what you can. Enjoy. Eventually you'll reach the ceiling and then have to make big, costly decisions.

I'm in the 265rwhp range...and it's fun. No traction issues and able to play with some fun cars. I only have traction issues when it's wet outside. If I can make a solid 300rwhp and I dunno if I'll ever get around to building a motor. I'll probably end up stashing cash away and if a built block comes up with all of the documentation...i'd get it and swap it in.....or just save up for a lightly built FM short block. Honestly, I need to sink more money into a better LSD unit :(

200rwhp is definitely "fun" though. Enough power to light up the rear wheels, enough power to get moving on the track, enough power to surprise a lot of other cars on the street from a dig or slow roll. If you want to make 200rwhp feel like a lot more, turn your car so the powerband is realy pieaky

I've watched a friends ~250rwhp miata walk C5Z06's before. Especially if the 'vette owner can't drive.

You could walk a Veyron if the driver can't drive. Skill is king on track days. With twice the power the vast majority of us are still slower than winning SM track times. You gotta have the skills and that comes with seat time, training and the right genes.

Edit: nm 220-230 seems like a happy place anyway, if I were to build the motor in the future it would be for fun and to keep it going, I don't like the idea of throwing motors away.

What does a mild build list look like?

iTrader: (9)

I want to say yes, but why would you dismantle an entire engine and NOT replace the pistons. There are good deals on pistons that make not replacing them on a built engine not so smart IMHO.

I have been happy with ~150 whp. It's not fast, but it is fun having a little bit more power. I'll hang with a GT and thats about it, but street racing is for ****. I just like getting crooked.

It also helps to have a bike, it satisfies my speed-needs.

Yeah. At ~265whp I would get tugged on just a tiny bit by C6Zs on track. They'd be a joke at 300whp.

Go drive a Stage 2 STi (chip+TBE, ~270whp) - that's what 200whp in a Miata feels like.

12.4:1 AFR and 220kpa, eh?

edit: 110% duty cycle, 20+ degrees of timing at 19psi around the torque peak, all sorts of bad stuff going on there.

Holy ahit that log is heinous!

Nice to know, now I just need to get one of these posers down here to go.
