Such a frustrating weekend ... managed to sell my yellow car, and taken a deposit on my V6 kit as well as selling various other bits. All that meant I had enough cash to buy the car I had my eye on ...
So I now have one of the coolest cars I've ever owned sat on my drive. It needs a few bits sorting but it's 90% there ... most importantly it has an MOT so I can drive it. Or I could if I didn't have 101 family things to do preparing for Christmas .... no fair!!!

Is this a car with extra cylinders?

Is this a car with extra cylinders? It does indeed answer that description ... Russell |

So here we go... this is the new car, pretty standard looking. I'll ditch the chrome mirrors for some standard ones but that's about it for now  The only external clues that something's going on are fairly well hidden  Inside is pretty standard, it even still has the original radio. Seats and steering wheel are temporary, I'm looking for an original pair of tombstones and an oem ish Momo wheel  Under the bonnet is where you get a few more clues  Yup, this is going to be a very interesting winter! I don't have too many plans yet ... mainly drive it and get used to it before I do anything. The diff is currently open, so that will be changed once I've done some calculations on what ratio I'll need. The wheels are ... well, very 90s, and the tyres are T1r so they need to go. Once I've found a decent replacement. Gutted my Watanabe wheels won't clear the brakes! There's a few things I want to do to make the car a bit more mine, but I'll try to resist for now, I kind of like the sleeper look it has going on Russell |

looks a neat conversion, what gearbox & diff are used? and, I'm waiting with for your decision about the v8 being better / worse than a 4 cylinder in the 5's chassis  and... What would you do diferent?  Rich. |

Brake calipers are Hi Spec, not as common as the Wilwood but from what I've heard they work better.
V8 vs 4 pot ... no contest really, they weigh about the same but the V8 has twice the power and 3 times the torque. There is a bit of extra weight in the gearbox bit that's low down and central so the weight distribution is barely affected.
I know some people would argue you can get the same power with a turbo conversion, but unless you spend crazy money you'll never have reliability. It's just pushing the engine too hard, just go to any track day and the broken down 5s are always the FI ones. If anyone feels the need to play top trumps, the standard internals can take 700bhp ...
The box is Supra, the diff is RX7. There's a few bits I'll change,
But nothing about the installation, I can't think of any way of doing it better

There is a bit of extra weight in the gearbox bit that's low down and central so the weight distribution is barely affected. Nearly 100kg heavier than a 1.8BP before adding additional weight for the gearbox. Basically doubles the weight of the drivetrain, most of it situated in front of the car's center line. Weight distribution will be heavily affected. Might not be the best solution for quick laps around a track, doesn't make the v8 rumble less cool though.  |

Weight distribution will be heavily affected. Might not be the best solution for quick laps around a track, doesn't make the v8 rumble less cool though. Basically, no it's not. There's a lot of guff on the forums about how much these engine swaps weigh, usually taken via Chinese whispers and gossip. The engine weighs a lot more if you use all the ancillaries off the standard engine, but you don't use them all. The subframe is a load lighter, you ditch the PPF, the intake is lighter, exhaust manifolds are lighter, some pieces are just ditched etc. Overall weight gain of another swap (taken from a complete car being weighed before and after the swap) is comparable with a turbo swap. Put another way, this car started as a 1991 1.6, and even after the swap it weighs less than a Mk2. Weight distribution front to back changes by 2% There's a reason Keith from Flyin Miata ditched his turbo and went for a V8 swap for his personal track car. And it's not because it was slower Russell |

I'll try to get some solid info down on the relative weights ... Got me intrigued on where the weight is gained and lost, and what the overall weight of my car will be. I'll be taking most of it out when I get it resprayed, so will check the weights then, however a quick Google has come up with this
Supra R154 gearbox 46kg dry
MX5 gearbox 36kg
Gain - 10kg (less than I thought)
1UZ engine & basic ancillaries 195kg
MX5 engine & basic ancillaries 131kg
Gain - 64kg (More than I thought)
Standard subframe 15kg
Crapengineering subframe 9kg
Loss- 6kg
MX5 clutch & flywheel
Thor Racing adaptor plate, clutch & flywheel
Gain / Loss-
Std 1.8 front brakes 21kg
Hi Spec front brakes 12kg
Loss - 9kg
PPF
Gearbox brace & diff mount
Gain / Loss
MX5 manifold & exhaust
Custom manifolds & exhaust
Gain / Loss
Still lots to confirm, currently at 59kg gained.
I'd be interested to compare that to the gains a turbo build would add ... especially as the turbo kit (intercooler and piping, turbo and manifold) will sit further forward than the weight gain in this kit (engine, gearbox)
So a turbo kit, minus the manifold (assuming the manifold weighs about the same as a standard manifold) is about 30 to 50kg according to Miata Turbo. So I'm currently at 10 to 30kg heavier than a turbo'd Mk1 ... with a few more sums to be done

Love it, sure I remember someone weighing theirs and like you said it only changed the weight dist 3/5% forwards
