Hi!
This is my first post, and I wanted to go straight to the point
I am a student who owns a Miata NB 1.6l in Europe, and my friends and I want to try to turbocharge it.
Sadly, because of living costs etc, my budget only comes down around 600 to 700 euros.
So my question is, is there any way to turbocharge a Miata NB 1.6l with around that budget?
It doesn't have to add to much horsepower, it would be nice to bump it up to around 150, and that would be enough. So power isn't much of a concern.
And if it's possible, how could I make it a bit more reliable?
Thank you very much!

 

It's not possible for 3 times that amount, but welcome to the forum. Maybe around 4 times that amount you can begin.

You will need the following items at a minimum:
A standalone ECU
A wideband O2 sensor and decoder
Larger fuel injectors
An IAT sensor
A turbo
A manifold
Oil feed line for turbo
Tee fitting for oil feed line
Oil drain line and fittings
Drill and tap the engine oil pan
Air charge pipes
Air charge silicone hoses
T-clamps for silicone hoses
Custom downpipe from turbo
Welding/connection to existing exhaust (why not a full exhaust at that point?)
Paying for tuning if you don't know how
Paying for the subscription to Tunerstudio or similar if you are tuning yourself

OPTIONAL BUT RECCOMENDED:
Stronger clutch and pressure plate
1.8 rear differential and axles (1.6 differentials fail at stock power levels regularly)
Intercooler

Welcome to the forum. I don't share this list to discourage you, but to share the reality of the situation. Reading the sticky threads will help you understand further. Good luck.

 

Thank you very much!

 

Just to elaborate a bit on sixshooter's post (which I agree with). You can achieve your modest goal BUT at the expense of sourcing and bodging together a conglomeration of used, and/or new "Chinesium" parts which will prove to be unreliable and a constant source of pain and frustration in the long run. You can;

Get a knock-off turbo from China (that will eventually leak oil, burn out the bearings, begin smoking and fail catastrophically eventually)
Source some yellow-top (RX-7?) injectors for marginally more fuel flow (but ancient tech)
Find someone willing to sell a MS2 for cheap (or free - which will give you the ability to tune, but with limited capabilities)
Source a log manifold that will work with the turbo (good luck with fitment and watch out for warpage and/or cracks)
Search the 'net for a "compatible" wide-band O2 sensor on an older car and then figure out how to adapt it to the ECU after snagging one from the local junkyard
Find a kindly old guy in a muffler shop that will make you a downpipe from the turbo to the existing exhaust (or bodge something together yourself and probably die from inhaling exhaust fumes)
DIY your oil and water lines (then do it two or three times again because of leaks, breaks, etc...)
DIY your charge pipes (better buy extra, you'll need it)

Optional but "I don't need no stinkin'..."
Clutch & pressure plate (if you get beyond 200WHP - doubtful - you'll burn up the stock plate eventually)
1.8 differential and axles (ditto)
Intercooler - EBay or equivalent will suffice...for now
And while we're dreaming...how 'bout a 6speed transmission - but that's your whole budget right there

Unaccounted for costs;
Many nights spent trying to figure out how to put your jigsaw puzzle parts together
More nights fixing things that you didn't realize you did wrong the first time
Hours / days / weeks / months climbing the steep "Tuning Curve"
Replacing cheap parts with better ones (as money allows) because of poor performance and/or failure
Taking the bus / train / or paying friends for transportation because your car is down
Regretting all of the above decisions and joining a monastery

See, it's EASY!
