I have been planning to make my car a little more useable on motorways and preferably quicker (that's always got to be the way) basically I'm not going to last for ever in the 55mph club lol
I have found an MX5 that is being broken for spares, it's a 1.6 import with 115BHP and I've been having a look at the ratios to see if it's a pairing that will work well. Here are some numbers, sorry to bore...
Gearbox ratios MX5 (:1) - 1st 3.136 2nd 1.888 3rd 1.33 4th 1 5th 0.814
Gearbox ratios Amazon (:1) - 1st 3.13 2nd 1.99 3rd 1.359 4th 1
Diff ratio MX5 - 4.3:1
Diff ratio Amazon - 4.1:1
Looking at this keeping the original diff will actually give me a car that's a better cruiser than the MX5. Spot On
The other items I need to collect then;
if I decide to lose the injection...
A set of bike carbs
Megajolt, to run the ignition
A custom intake manifold
And/or if I keep the injection...
I've got a Jasma exhaust manifold already
A hybrid of the two propshafts
A hybrid of the two speedo cables
The clutch master cylinder off the MX5
The rad from the MX5
A custom exhaust
A fuel pump
So first thing will be to grab the MX5 parts that are still on the car and get everything cleaned up while I collect the rest of the bits...
