You can find several different iterations of the kit on ebay or amazon. It's a delphi weatherpack kit made by a private supplier. You'll want some good weatherpack pliers

Added a fuel gauge while I was doing the fuel system. I don't use miata gauges, so I didn't have one before. This holley unit is programmable to E/Full so it really made it a snap, uses stock sender wire and has an adjustable low fuel level warning.  |

Long day at the drags. Short of the story is, it's a silly fruitless exercise without drag tires. I almost walled it a couple times on the big end, just randomly getting loose. Was great fun though, and coaxed some semi decent times out of the baby 205 street tires. Tech line  Tech line  Waitin  Staging lanes  In the burnout box  Best pass of four (12.0, 11.7, 11.6, 11.5), had to let off twice for traction/wheelhop and baby it out of the hole. With a set of drag tires it's a solid 10 second car no doubt.  Videos were took, but those wont be uploaded until late tomorrow or monday |

I should add we weighed in at 1930 on the scales today with 3/4 tank. Fat lady. It's 12# lighter with the hoosiers on it, though, so that's good at least. Weight reduction to do in the future Wilwood front brakes (9/corner = 18 lbs) Wilwood rear brakes (hesistant because I like the e-brake, and the weight isnt great -3lbs/corner) Lightweight clutch and flywheel (64 vs 24 = -40 lbs of rotating mass, this is a big one) Lightweight driveshaft (-5 lbs) Lithium battery? Current battery is 26 lbs (20 lb savings possible) V8R suspension lower arms (Average 4# a corner, so 16 pounds here) Tubular rear cradle (10-15 # estimate) So there's around 110 pounds that can be removed with the wallet to do so (which I certainly don't have, at the moment) Things that are adding weight vs a typical V8 build Accusump +3 extra qt oil (~20 pounds) SFI steel bellhousing (~20 pounds heavier then stock) Odd things that can possibly be done -1 Engine fan (-8 pounds) Custom forged wheels (-3 lbs/corner, but $$$$) Lightweight Alum or polymer fuel cell (  ? pounds, probably not much) Remove side panels (nope) Remove body panels (double nope) T5 transmission (50 pounds savings vs the T56 magnum, but would require a new trans mount, driveshaft, clutch, yada yada, and would lose a lot of strength) |

Really impressive times. Let us know if you ever throw the slicks on and take it out. I'm sure you'll be safely into the 10s. Got me curious to see what my stock one would do. (not well I'd imagine). But if I ever did I'd soon want 4 more cylinders.

Willwood rear brakes can have e-brake. If the weather holds -doubtful- I'm installing mine tomorrow but I have the kit (from FM).

2 hours in the opposite direction for another autox today. Had a real close battle in EM with a brunton stalker (Lotus 7 clone) and lost out by 2 tenths to him, borked my best run on top of forgetting my rear wheel spacers at the house, tires were rubbing the heck out of my frame and slowing me down in corners. No excuses though! Still finished second auto and third overall (kart) out of 87. Not bad www.wichitascca.org/results/2016/apr3_raw.htm |

Minor note that I'm really happy with how the car is setup right now, with just a touch of on throttle oversteer. I think it could use a little more spring rate, but it's really close right now.

Very nice. Looked a little squirmy but that you mentioned already. Good work.

Head swap started. What a mess. Should be done by tomorrow night and back to the tuner Saturday. |

Doing anything else besides the CNC heads?

Bigger fuel injectors to feed them, but that's it. Engine's close to its potential - all that's left is the intake mani and throttle body where another 20hp is hiding ($$) down the road. Going back to the dyno sat, hope to make 450 from the previous 404.

The old, failed, mystery mile head gasket (this was a rescue motor, after all)  Closeup of the failure spot, you can see where coolant seeped in and cleaned the piston  Cleaned up around the failure spot, you can see the pitting caused by the HG failure - basically combustion pressure leaks out and boils the coolant, damaging the deck surface (over time).  Fortunately all of the pitting was localized here, and with the new style MLS gaskets we are using, they block off this port entirely and seal around the pits - AND the pits dont go into the fire ring. It's a win/win, lucky day. This is what the new style gasket looks like, notice that coolant passage is blocked and where the sealing compound is.  New head intake port  Exhaust port  Chamber  As it currently sits, about halfway done.  The new heads should add around 50 horsepower, compression will rise from 10.1:1 to 11.8:1 as well. Heads are the AI 219cc high compression port. |
