It's a stock evo manifold, we have no plans on installing it beyond joking around.
We have a lot of the hard stuff out of the way like the clutch, wideband, and MS. But the expensive stuff like a torsen swap, manifold, and DP are still left. We figure with the right custom manifold we could bolt on the Evo cast turbine housing (kind of like FM's cast DP elbow) and fabricate our own DP fairly easily, but that's still $1000+ in diff, injectors, and manifold we could spend on track days, safety, or a 1.8.
I told him to keep his eye out for RX-8 injectors, they're an upgrade in design and would be a small but big step forward in a turbocharger in the distant future.
We'd be looking for something like one of those $100 FM manifolds. We'll keep dreaming.
It doesn't help that Martin turbo charged his purple Galant for something like $800 all in, so he's slightly convinced you can do the same on a Miata. A programmable stock evo ECU, a few stock fueling parts, stock cast manifold/turbo/dp, and you're done in the Mitsu world.

I hear you there, that was why Im going NA 1.8 with my cheap build, even though I fab everything myself. (for now)
Turbo, IC, IC pipe, Manifold (even a log) and downpipe all break my budget when you add it up.

Steering rack spacers and R package tie rod ends for Lazarus in an effort to combat bumpsteer once the car is below 12 inches hub to fender. I must say excellent service from Rosenthal Mazda.

A parcel showed up today from Roush Yates Racing, I opened it eagerly like a kid on christmas and found Laz's new oil cooler. Its a small Setrab unit that is a hand me down to Lazarus from some form of stock car racing. Other than a few scratches the piece is in fantastic shape, no dents or massive fin deformation, the plan is to mount it in the mouth of the front bumper in front of the radiator and attach some mesh to the air guid to prevent it from being hit by debris on the road or pieces falling of other track cars. Even came with a nice Roush Yates Racing decal.
Car now has a GT3 Cup Car harness and a cooler from a stock car, hopefully more cheap ex racecar parts find their way here.

Directions for making a free Momo wheel spacer fit your free Nardi wheel.
Step #1: Select the proper spiral titanium nitrated coated bottom ground 1/4-20 tap and drill. This particular $100 tap may be over kill.
Step #2: Drill out Nardi wheel for slightly larger 1/4-20.
Step #3: Align wheel with Nardi holes between Momo threads, center, mark, drill, and tap first threads.
Step #4: Clamp down with first threads with temporary bolt and washer to protect paint. Nervously center punch remaining 5 holes, repeat drill and tap instructions from step #3 x5.
Step #5: Finish bolting down and step back unsatisfied. Furrow brow trying to think what's missing...
Step #6: Raid wife's garage.
Step #7: Select possible candidate colors and test.
Step #8: Apply flair.
In case anyone was wondering, I settled on Sally Hanson Salon #360, "Wine Not".
The End

Well, the kind folks at LazFab need some advice from the MT crowd. We've been trying to iron out a AFR target table for our little 1.6, but can't seem to get a decent one. We've tried this one:
But it still seems to stay a little too lean (or sometimes a lot too lean) in higher RPMs, so we're thinking about trying something like this:
We'll add in some cruise cells after we iron out the full throttle running.

Well were auto tuning, and letting off in fear of explosions, even N/A. I'm wondering if it's not getting a chances to add enough fuel, quickly enough. Could be I just need to do it manually or try changing autotune to "easy".

This is the weird thing, I drove the car about 25 minutes in a variety of settings with several WOT pulls to the top of 3rd gear, during which the car was autotuning. Compared to what we started with the numbers were much better, no more stuttering or bucking with AFRs shooting in the 16+ @ WOT like before. It wasnt perfect but much better. I then parked the car and went inside curlys house to help with a TB/WP job on another car. When I went to drive home, all of the bad behavior was back, car would lean out massively going WOT and then idle super rich around 11.6. Curly has the laptop with TS on it and does all of the tuning and so there wasnt much I could do since i was driving this car in a torrential downpour on bald RA1s on the freeway and my concern was trying not to die on my way home. We discussed whether the autotune had actually saved and came to the consensus that it was. I think the next step is to actually have curly in the car while Im driving and monitor the autotuning and see what the car is trying to do.
last time we tuned the car was on a dyno, the car did not have a wideband or IAT installed and we still had the stock 1.6 injectors. We barely touched fuel and just played with spark and thats how we got our 115whp. Im hoping with a WB/IAT installed and some playing with fuel and then going back to the dyno to adjust spark we can have more gains. So far however the fuel tuning is proving slightly frustrating

Did some more auto tuning today, night and day difference, car feels terrific, I'll let josh post up our maps. Next we will be playing with spark on the dyno and see what the little 1.6 can do.

No one cares about the god damned maps.
Look, a pretty multi colored spreadsheet. OOOOOH....
Made the 7000+ cells a little more rich to compensate for the fact that Martin likes to be a:
COMPLETE AND UTTER ******* MORON
and rev this completely stock 1.6 to an indicated 8,000rpm.

Ive been revving lazarus up to an indicated 8k for roughly 3-5 seconds per lap around our local racetrack for the past few years, the issue is the gearing, I run out of 3rd and 4th gear respectively right before I need to brake for corners that require 3rd and 4th respectively but I dont want to add a total of 4 extra shifts per lap. I normally shift at an indicated 7000-7200 otherwise.
