    Yeah, you're right. I can still run my stock gears thankfully until then

        looks like that ebay crap... 'obx' or some other knock-off.... i've HEARD from people being ballsy enough to use those gear that they swap out the bolts.. Not sure how it's faired in the end..

          The gears are some ebay brand, however they'll be temporary..
          Here's a photo of the failure:


          Participated in a car show yesterday in Buena Park, CA. It was a blast. I had the only 2nd gen Escort there and received a lot of positive attention. The trip out and back was fun. The delta cams are a big change in power, and I encountered a couple of strenuous hill climbs where downshifting was necessary. However the near sea level altitude of L.A. was awesome for the car. It pulled hard from 3500 rpm and up. I can now feel the restrictions in the motor though. Time to upgrade.

          My plans for the year are swapping to a 4g64 intake manifold and a Focus SVT exhaust manifold to accompany Carlos' Evo 8 ECU. With this combo, I should be around 150whp on stock compression.. then comes the bp4w head and some port work.

              Since your staying N/A i dont think losing the VICS by swapping to the Mitsubishi manifold is the best idea, and I also wouldnt port the BP4W head either. It will make more power than your after on untouched ports in N/A form.

              I would recommend using the Kia/second gen BP upper intake manifold and doing some mods to that. These are only my opinions though.

              Miata 10:1 pistons are also a good oem upgrade.

                  Well I can see your concerns; they're all pretty good points, however i find myself wondering why you wouldn't want to upgrade the stock intake manifold? I understand VICS allows more airflow beyond 5,000 rpm, but I can feel my car is choking out around 6500. I have heard the kia upper intake is slightly taller, indicating an increase in plenum volume. Would I run into trouble with a factory 2.4L intake manifold now that I have goals for higher compression (bp5e pistons) as well as camshafts with higher duration and lift? Are you concerned about velocity with a larger intake manifold? Carlos noted to me he made 140hp on just the intake and evo ecu, stock exhaust manifold. I feel that's pretty substantial, since most bps dyno under 120whp with bolt ons.
                  Also, on the cylinder head, I do not intend on lowering the port floors, only doing bowl work and removing casting flash. Is there no benefit to doing this?

                    As far as the VICS I was mostly talking about your low end power suffering from losing it. The Kia upper is about 1" taller and has a tapered plenum which will give more even air distribution to each cylinder since that is also an important aspect of any manifold. It doesn't really have more plenum volume and may even have less but the runners are longer which changes the wave tuning aspect of it and it's torque/power peaks. The guy that ended up buying it from me said it felt like it added power top to bottom. I did Ryan's secret manifold porting and removed/reduced the dead spot where the 2 runners merge in addition to a larger throttle body. My opinion is if it feels like it's losing power above 6500 then put on a larger throttle body.

                    Carlos does have far more knowledge than me about tuning and he has tested that manifold so he obviously has some experience to back up the power claim, but I feel like most of that power came from his tuning and much better engine management compared to using 30 year old electronics. Personally I would like to see a dyno chart of a stock BP or bolt on BP vs his 140hp dyno run just so I could see if there was anything lost in the low/mid range with his manifold.

                    The reason I say leave the head alone is that there is a guy that made 170+ rwhp with a Miata N/A with an untouched head. The only thing done to the head was a massive head shave to bump his compression to 11:1 on top of the already stock 10:1 compression Pistons. He had more done to the engine than this but the head and bottom end were untouched, just ITB and cams/valve train and engine management being the major mods. I am a firm believer in velocity being far more important then how much CFM a head can flow based on this and a number of other examples I have found before, since it seems that the first bad mistake that everyone does is "port" the head for more power not knowing that they just made the engine a dog and made the power more peaky and narrow. Once you add a turbo then all these details become far less important.

                    maxbore.com will port your throttle body for $99. I have used them and they did a wonderful job.

                      You have a lot of great information here! Thank you for your reply. I took your advice and bought some 10:1 pistons for my build.
                      More parts on the way soon.. got a lead on acl race bearings for a good price.

                          My rear brake upgrade arrived today. It's from a miata with the sport suspension package. Just waiting on the centric rotors to arrive

                            Just received some mx3 rear lateral arms for increased track width, as well as some bp05-ve 10:1 pistons and rods.. waiting on some centric rotors to pair with my mx5 sport suspension rear calipers.
                            Gonna check if my mazda gtx lateral arm bushings fit the mx3 lateral arms..

                              Did the miata sport brake swap today as I had the day off. Felt great to get some solid work done on the car.
                              I used my escort gt calipers, the miata brackets, miata rotors, miata pads. I had to trim the dust covers back to accept the larger rotor. I used 2 washers behind the bracket eyelets to give the proper spacing for the rotor and pads.

                                I had meant to write you back! Well boost is fun! I have a turbocharged zx2 as well which I enjoy very much, and I really just wanted to be different with this build. Not many go the NA path, and I really enjoyed this car without any forced induction. It's been my daily driver since 2011 and it's a blast to drive. Recently seeing Carlos break some serious barriers with the bp platform has me inspired to break some barriers of my own. 👍
