Hi guys long time lurker here
Thought it was about time I made my own build thread
This is my car after owning it for a year I repainted it with my dad.Sadly got very few photos of this and all the work it entailed
Fast forward until 2013 when I found mt.net and a cheap turbo set up, super laggy t3/t4 knock off turbo complete with a gtx motor and "bolt in and go"
some joke that turned out to be.
I had all the pieces "ready to go"
so the assembly began
The old 1.6 engine had to come out so a good mate of mine helped me swap everything over and put the new motor in.
Then came to bolt the manifold on
It was quite warped but I didn't notice and bolted it on anyway
(The manifold was made of decent material just wasn't made very well)
got everything bolted up turbo oil lines etc.
The IC pipes were made of steel and were very rusty inside and didn't line up at all. So I decided to trailer the car to have the new aluminum pipes made up
from a local fabricator.
He mentioned that i had an oil leak (I didn't think much of it at this stage as the car was still in pieces)
The car was almost ready at this stage just needed the engine management sorted
This was also when I discovered megasquirt from you guys.
A local guy from up in the north island (I live in the south island) was building megasquirts, I picked one up from him. Its a ms1 extra which is very basic
and I soon had that running.
I couldn't get it to run properly. The problem was very simple in the end but i tried everything else first coil packs, leads ,plugs nothing made a difference
Until one of my mates came over and wondered if i had put the fuel lines round the wrong way. When I had swapped the motors (was 1.6, gtx motor was 1.8) Instantly started right up and ran decently.
After feeling like the biggest idiot the car was ready to drive
The ecu had a base map for a gtx motor so it was reasonably close and ran smoothly
I got an innovate lc-1 and got that wired in and the car was ready for veal
I had been waiting about 6-9 months to drive the car at this stage
I Grinned like a kid with an ice cream the first time I hit positive pressure 5psi
wastegate spring was all I ran to start with. The car was transformed it was much faster and I was hooked on boost
The next thing I added was a greddy mbc which did work ok and I hooked it up wrong the first time and hit the boost cut (250 kpa) talk about jerky
I thought I had broken something. After doing some research I figured out the vacuum lines were the wrong way around.
I slowly increased the boost 1-2 psi until 12 Psi man the car was fast now.
At the time I was living at my parents house and they have a sign from the petrol station intersection and the open road sign (100 Kph) its literally 400m or a 1/4 mile. This is how I used to test my modifications. The standard mx5 did 140kph by the sign but now it was doing 175-180kph depending how many gears I did.
The car stayed like this for about 6 months I had to get certification for the turbo and the bigger engine. Its around $500 and if you change anything you have to get another certification, its a frustrating system.
To save myself from having to go back for a recert a friend of mine talked me into swapping the suspension to coilovers.
I found a tidy set of tein super streets from the local mazda wrecker (who is also very into Mx5s)
Once I had them done it was ready to be road legal again,
I daily drove the car for six months and the car turned heads and I had lots of people try to race me down our motorways (The best fun beating V8s wrxs etc)
A drag meet came up in Oamaru which is 300km south of where I live in Christchurch, so a few of my friends and brothers came down with me.
I knew theoretically my car could run 13s (according to my sign test)
My uncle races an old Ford Fairlane which is fairly serious 600whp+ He thought I would be doing 14s as his best was 12.7and it wasn't a prepped track.
I even raced him a few times for fun
My best was a 13.3 and I was surprised a little mx5 with a turbo could be so fast. I beat a few skylines an rx7 and some other v8s all who were shocked
Then came the drive home. I decided to check the fluids etc and i had used almost a liter of oil. Wasn't sure whether to be concerned or not. Drove back home to Christchurch
