    Winter goals...

    So I have finally made the 1st MX-3 BP w/ ITBs in the world. Well I want to take further steps since I want to be in the low 13s N/A. I want to have this parts for next summer. With these mods, I think I can reach close to 200WHP:

    -99 Miata head (ported and polished)
    -Oversized valves
    -Cams
    -Carbon fiber cam gears w/ aluminum lower gear (if they ever get finished)
    -Valve springs
    -High compression pistons (11:1 CR)
    -Hayabusa ITBs (52mm instead of 44mm)
    -Velocity stacks
    -255 Fuel pump
    -SS 4-2-1 header
    -Full titanium exhaust (maybe aluminum)
    -205/50/15 drag radials
    -re-tune

    I'm going to try to collect all these parts this winter for next summer. I will update this every time I get one of the parts that is on the list. Comments are welcomed

    Sounds like a good list, but why titanium exhaust? weight?

    also you might want to run an electric exhaust cutoff, that should help your car breathe HUGE when you're at the track.

    Also are you going to have any crank work done? What about getting casting marks removed from the connection rods?

    Are you running a small or big nose crank too? There's some UDP options out there!

      You need to work on some weight reduction. That will honestly be the quickest way to the 13s.... also maybe an LSD???

        Titanium is lighter and the hotter it gets, the stronger it gets. Cut off would be nice, but I think I want back pressure so I don't loose torque. UDPs are no good, they don't have dampers so it will make my big nose crank unbalanced.

          That's true, Maybe strip it before track day? LSD means I got to get a G-series tranny. I can get a Kia one for cheap... Man this is going to be like build number 3! lol

            Well what happens if i told you of a factory crank pulley? same size, just no extra ribs for p/s or a/c...just bare minimum

            Festiva 1.3L engines, idk if they have big nose crank pullies, but I definitely know they have small nose.

              Since you're going thru all this might as well balance it. Light weight con rods and micro polished crank. Since you have ms why not aim for 13:1 or higher

                IMO these things are completely unnecessary and wont help you make more power. If anything, they just add weight and expense. You're NA, unless you are running on a road coarse, oil temp isn’t much of a concern. The stock FPR works just fine, and you don’t need an adjustable FPR unless you are using the wrong size injectors. At that power level, the stock fuel rail will still distribute fuel just fine, and its probably lighter.

                I'd actually run an aluminum exhaust system after the header. Light, cheaper, and should work just fine. Heck, your cylinder head is cast alum and that’s where the exhaust is hottest...

                Also 225 50 15 drag radials are probably too tall for an NA application, I'd probably go for 205 50 15. if you do want 225 50's I have a pair for sale, though...

                  The crankshaft has been worked on already. Lighter rods would be nice, but the stock BP ones are just fine. If you can find 13.1 pistons let me know. The highest CR that I found was 11:1

                    OK lets scrap the fuel stuff since you are probably right.

                    I was talking to Frogi about the titanium exhaust and he said the same thing. He said to make an aluminum exhaust. I told him that it would melt, but you have a good point. I might try that! Oh another thing that concern me is that to increase exhaust velocity, you want to keep the hot air inside the pipe. With aluminum the heat would be conducted through the aluminum leaving cold air at the tip.

                    205/50/15 would probably be better.

                      just trying to offer some constructive criticism

                      if you're worried about the heat thing, you could try some sort of spray-on exhaust coating that's designed to help control heat. the spray on stuff always burns off when you use it on the manifold, but i'd think it would hold up much better on the rest of the exhaust where the temps are lower

                          i know the aspire pulley works on the large nose crank. thats what im using. its lighter because it has no spot for ac. but im running ribbed pullies instead of v belt
