Jumping back a ways, since I think I may have misunderstood you.

Why would you allow the engine to move?
|
Engines do move a bit- it's normal- the stock Miata engine really moves quite a bit! The engine mounts are rubber so that the vibration/ harness is dampened.
V8r's engine mounts are MUCH more solid than a stock Miata. Poly bushings will only allow the engine to move slightly. I think it will be fine. |
I believe Full Tilt Boogie was being facetious.
But yeah, the V8R mounts will reduce movement a good bit. -Ryan |

The car is now drivable. I still have to figure out why the coolant is not circulating- I expect that I've still got air in the block, but I did drive it down the driveway and back up- everything is working! I can tell already that the car will be RAW and FAST. Pretty much all of the rubber isolation stuff and sound proofing is gone, so she's very racy.
Still have some minor sorting to do- connect CAN lines to dash, wire fuel level sending unit and brake lights, alignment and scale but she's alive!

Unf. That last picture.
I need a moment. |
Good lord that's sexy. Time to give my flip ups an eviction notice.
Any plans to relocate the lighting elsewhere? |
Yours looks good, can't wait for a video.
mines getting there, just working on getting some mock up motor/trani brackets |
What the update...
|
Earth to Carnut.

Yeah, I'm here.
Driven the car roughly 100 miles now. Doing The Jzilla Track day at Road Atlanta on the 8th. I added a header tank to help bleed the system and now its fine- stays around 180'. Also got the dash up and working using the OBD2 protocol from AIM. Veracity built a gizmo that will allow me to display fuel level on the MXL which is neat. The power steering pump was also an issue- it only lasted about 25m without fluid. However, I found a Dorman pulley (with a bearing) that fir right over the factory ps spline which is threaded, so that's been working great. I also installed a Vitesse Throttle controller which eliminates the ECU's delays in opening/ closing the throttle. Way more responsive. I will definitely take some more video on the 8th! |
Did you ever get the hood clearance figured out?

And now that you're on the road with it, what is your feeling on the getrag 3.42 ratio? That MV5 6 speed has a really short 1st/2nd and a really long 3rd, does the 3.42 make quick work of 3rd gear or does it drag on a bit? -Ryan |
Also in for the lighting situation. I have no interest in putting the barn doors back in, and would love to hear your thoughts.
Extremely jelly of this build. Absolutely proper. Hat tipped to you sir. |

Its spaced with washers and I used red lock tight on the bolt and so far it has not moved. I *think* the 3.42 will be a good ratio for the track, but for a street car the 3.2x the V8R used would be better. The ratios used in the AY6 trans are a little odd. 1st is a stump puller. Great for burnouts! 4th to 5th is almost the same but 6th is a good bit taller. We'll see... |
Lighting solution? Run during the day! Seriously, I may add some LED light strips.

The light mounts upside down onto the bracket. https://www.miataturbo.net/attachmen...ine=1433193440 https://www.miataturbo.net/attachmen...ine=1433193440 To mount the lenses I had to cut the ends of the housing off in order to get proper spacing. https://www.miataturbo.net/attachmen...ine=1433193440 Light output at night: https://c1.staticflickr.com/9/8686/1...b386e899_b.jpg |
Mmmmm... This is pretty much what I've been thinking as well. Thank you good sir.
You wouldn't happen to have a drawing/model of that fancy bracket you've got would you? :) |

What are your impressions of the 3.42 and the MV5? For the tracks out here, the MV5 actually seemed like a better choice given the gobs of torque, but bench racing and reality are often at opposite ends of the spectrum.

6th is basically an overdrive, with a big drop for the 1:1 5th down to 0.75:1. The thing I've tossed between, given a couple of our SoCal tracks that would see a 300hp car over 140mph, is whether it would be better to gear longer so that you don't need 6th at all at those tracks, but be stuck with longer gearing everywhere else, or just go short and accept that you'll need to nudge into 6th on the front straights for WSIR and ACS. You aren't accelerating much up at those speeds anyways, so I've decided it'll be better to go short on the rear ratio. So if we're considering a 3.46 and a 3.23 rear end and an MV5 transmission, we get the following at 7,200rpm: 3.46 3.23 34 37 1st 65 70 2nd 96 103 3rd 120 129 4th 143 153 5th 170 182 6th Assuming 205/50-15 tires So how does this look for your Southern California tracks, such as Streets of Willow, Big Willow, Buttonwillow, Fontucky, Laguna Seca (okay, not SoCal but who doesn't want this on your list)? |

I've got a whole mess of graphs that I've compiled to play with all the different ratio options. The main rub with the trans from the Camaro is the ratio spacing. Here's the Camaro's 6 speed with 3.42 compared to a Miata 5speed with 4.10 gearing to show just how short that 1st and 2nd are:
https://www.miataturbo.net/attachmen...ine=1433445760 For the track, that's a useless 2nd gear, so I believe you're better off gearing for 3-5 use, rather than gearing long and having to dip into 2nd gear ever. Addressing the real issue though would be to use a different transmission... -Ryan |
This is a beautiful build.
How streetable is this swap? Can you retain AC and PS just like LS swaps? |
