God damn that looks good. I'm happy with my car as a track car I can drive to work a couple days per week. Look for Lotus Elise seats or Sparco Roadsters if you want to drive it more than once per week.

You want an mushroom shaped flat-bottom back to the steering rack.

Cam gears may give you more power, but you'll have more than you need at the track. It's going to be so much fun.

Nice parts list... nicer than mine

BTW Technoracer says that the 2001+ coils are good for 24+ psi.

I didn't know Hydra 2.7 was out. We have the same injectors. I'm on Hydra 2.6 and yes cold start in cold weather has kind of sucked. I wonder what other benefits there are though-- I'm kinda getting tired of having to pay and ship for lameass hardware upgrades.

How much did it cost for the IM welding?

Yeah the coils are probably overkill but I just couldn't help myself.
I am waiting for the 2.7 upgrade to come back from them right now. 2.5 units had to have entire new board installed, I believe the 2.6 is just a firmware update. anyway there are a bunch of new tables and I am not a talented tuner but I will try and work with Tim Bailey to learn something when he tunes my car.
here is the list of features that hydra emailed me
The Hydra2.7 has complete new firmware and software along with new processor with onboard datalogging and new idle, boost control, aux map and long term trim strategies. The 2.7 will also have capability to configure for additional sensors as inputs with configurability. Stage5 Epsilon has built in CAN Bus for use with external dashes, so you can run a dash and tune at same time. Hydra2.7 will be firmware upgradeable remotely without sending the ecu back. Each stage will be upgradeable to the next remotely without sending the ecu back.

You can also just buy individual Capabilities if you do not want the next full stage upgrade.

Stage 1 Alpha and Stage 2 Beta will be stripped down versions with less outputs and inputs then the current Hydra2.5 and 2.6. To get equivalent Outputs as the Hydra2.5, you will at least need the Stage 3 Gamma upgrade


Alpha
4 injector
2 inputs
6 outputs
Knock control

Beta
6 injector
6 inputs
9 outputs
Aux Fuel/Ignition Map
Launch Control
Intake VCT Control
lambda Target
Tip-in Enrichment
injector phasing
Basic boost Control
Staged Injection

Gamma
8 Injectors
10 inputs
14 outputs
Change datalog channels
Antilag Fuel /Ignition Map
Exhaust VCT
Immobilizer request
Valet Request
Flat Shift
Alternator Control
VE Mode
Alpha N Mode
Boost Compensation
Gear Correction
Individual Fuel and Ignition Trim
STT Ignition Trim
Throttle derivative
3D maps
Manifold Pressure delta trim

Delta
Steering Load
Traction Control
Coolant Temp RPM Trim
External Map sensor
Engine Speed Delta Trim
Idle speed Error Trim
Calibration Input Maps
Fuel Pressure correction
TPS Position Trim
Barometric Compensation
Fuel Temperature Compensation

Epsilon
Onboard CANBUS Control
Two Internal feedback outputs
Humidity Correction
EGT Correction(requires CAN Expansion Box)
Flex Fuel Support
External Wideband Support
Vehicle Speed Pit Limiter

So which coils did you go with? I saw a bunch of coils on the DIY site.


Humidity correction. That's interesting. I wonder how it would deal with water injection :|

Fuel Temperature. Neato. Useful for all out drag guys?

External wideband-- does this mean you no longer need the stupid proprietary Hydra wideband sensor?

EGT correction- nifty. If only this could be used with the knock sensor for timing autotune!

wow. Beautiful. I'm glad to see it all together, that exhaust looks awesome! I too keep paging up to the first post

Did you have an extra set of MVS flanges in your MVS box?

Yeah the manifold and downpipe look awesome Tim! Thanks, sorry it took me so long to get it together.
No we didn't have any extra flanges

Oh yeah almost forgot the cutting and welding on the manifold was about $275 I think

I have the IGN-1A race coils-need to find somewhere to mount them and then get some custom plug wires made

Thanks for the info- will be helpful for some manifold work I'm shopping around for.

Ahh those coils!

Hmm I have thought about going to super coils just in case. When are you doing the upgrade? Maybe I can do it too and we can help each other with the R&D/testing.

Sure, I haven't installed the coils mostly because the main thing was to get it started and running first. I'll let you know where we decide to mount the coils and how. The wiring shouldn't be difficult

I agree with Hustler about those Exige seats. Easily the nicest/comfortable track ready seat I've ever sat in.

This is what my mechanic came up with to mount the coils. Looks pretty slick. It is actually mounted from the strut bar. Hopefully it won't vibrate too much

Hydra is back from upgrade. Coils are installed.
Tuning may commence tomorrow.
I have thought about the oil pressure issue and I will probably just bite the bullet and go with a full dry sump system from Armstrong Race engines as he already has a casting for a dry sump pan for the miata. it will probably be a 3 stage system but I am not sure if a 4 stage system would be able to pull vacuum in the crankcase and the head. Probably overkill. I'll have to work out if it makes sense to keep AC or if it will work. AC is just so nice to have in a street car. Seems silly to have the only dry sump street miata that I know of so complete conversion to a track car may be inevitable. Hmm aeromotions active wing, big splitter, diffuser, flat bottom-my wife is really gonna love that.
All this might depend on another miata project. Found a 99 with a full cage, low mileage engine, Teins, and willwoods for pretty cheap and am considering whether it needs an LS3 swap.

Why go dry sump? I do think that would be a waste. There are several tracked 350hp miatas here and they do fine without a dry sump.

Probably more for fun/interst. It does remove the oil pump gears as a potential point of failure during high rpm use and prevent possible oil starvation with heavy braking that others have reported.-of course at the expense of additional possible points of failure
It might free up a little HP in reduced windage losses/better crankcase ventilation.

Mostly just for fun though. oh yeah and it looks cool too.

Where would you mount the pumps? How much would the whole package run, new pan and all?

Pump unit is mounted to front of the engine with a custom bracket and runs on a belt drive attached to the front of the crank pulley/damper.
this setup would probably be around $2.5K might be more due to length of hoses as I would have to mount the oil tank in the trunk as there really isn't anywhere to mount a 2.5 gallon tank in the engine bay

Thumbs up to you if you do it!

Damn that would cost more than my turbo, pistons, and rods combined!
