NitroDann SE upgrade kitAfter very thoroughly servicing the car, including all fluids replaced with uprated synthetic options, new tyres, new brake pads, uprated cooling system etc etc I felt I had done enough supporting mods to start playing with power…
So began the rather daunting task of collecting the necessary parts.
Larger injectors: ID725sInjectors are “universal”, however these come with beautifully machined alloy adapters to fit the fuel rail, and connectors to solder/crimp on to the wiring loom.
Larger intercooler: JJR Cooling pro unitIntercooler install was straight foward, used the oem pipes with sections chopped off and rebeaded at the ends. Also used new 2” silicone joiners with Tbolt clamps.
BOV: Tial Q50Hidden in the bumper behind the foglight, the oem undertray and wheel well liners completely hide this. Makes the greatest PSHHHHH noise.
Standalone ECU: Haltech Elite 1500Behold. The most expensive part on the car haha.
Comes with an adapter loom, which required a few changes to work perfectly. Still in prototype stages, however I have been offered a completed sealed loom when it is ready.
WBO2: Haltech sensor + CAN controllerRequires constant 12V and ground, so I tapped underneath the fusebox for power and earthed underneath its bracket.
Very expensive, but i’m glad I went with the Haltech part, as it actually failed the first day of driving, threw a CEL and sent me into a panic attack haha. They remotely scanned the ecu, turned off the cel and told me it was fine to drive to them, where they replaced it instantly free of charge.
EBC: Haltech 3 way mac valveI mounted this in the oem spot like most people, as the oem wires are easy to tap into and it just requires a simple bracket.
I had Dann fabricate a different throttle body intake pipe, as I now have the BOV on the intercooler pipe. It also needed to be a tighter radius to clear the stupid FM top radiator hose.
I also had Dann fabricate me a new intake, as I wasn't having the BOV or catch can recirculate into it anymore, and I wanted an enclosed filter. You know, because the car is so legal in every other way lol.
Just one barb for the boost controller, and a gradual taper to the 3” Works Engineering Carbon Fibre enclosed filter with a bellmouth. Filter is braced off the intercooler pipe. MAF delete because Haltech runs on an internal MAP sensor.
And no turbo car is complete without a full 3” exhaust…
So this was done too. Gorgeous welds and perfect fitment as usual.
Set up consists of turbo back 3” stainless steel, flex joint, bullet high flow ceramic race cat, NO RESONATOR, Magnaflow sports muffler, 3.5” rolled tip.
How does it sound? Astonishing. Completely unobtrusive when cruising around daily, no drone, not loud but audible. It has a beautiful note on idle, screams on harsh acceleration, and the best part? The burble crackle and pop on engine decell/overrun. Words cannot describe the rumble that carries on. It certainly does not sound like a little 1.8L lol. In fact, I had a red P plater kid in a Pulsar ask me “Does your Miata have a V8 in it?”. True story, its that good.
There are a quite a few people who can vouch for how amazing it is, shoots flames and everything. Phenomenal product and responsible for a massive power gain haha.
