I just bought a 1991 1.6 miata and promptly pulled the motor to fix an oil pump leak and a rear main seal leak. I've been looking at some budget turbo setups and I just need some advice for how to get there. I need to do it on the cheap as I am a student, but with that being said I dont mind dishing some money out in places to make things reliable. I'll make a list of parts and I just want to know how cheaply they can be had

I'd like to,

buy a cheap used t25 (or Ebay?)
ebay cast log manifold
Find a used fmic off local classifieds
ebay or used ic piping
ebay lines
diy megasquirt (lots of soldering experience)
rx8 yellow injectors

what's a good option for a cheap Downpipe?

Unfortunately, you bought the wrong car.

You will need to spend 800 or $1,000 on a 1.8 rear differential and Axle shafts and driveshaft. The 1.6 diffs often fail at stock power.

The next big expense you cannot live without is a megasquirt ECU. Figure a bargain-basement unit will be about $400 up to build yourself. You will also need to purchase a wideband oxygen sensor at about $200.

Then you'll need a stronger clutch because the 1.6 clutches do not handle any boost at all. And the cheap ones on eBay don't work. Figure 300 to $450.

You will need injectors. Even used ones will have to be cleaned and tested so you don't blow up your only motor so figure 300 to $500. The eBay RX-8 injectors are almost all fakes and not 550cc.

I almost forgot, you will need a variable throttle position sensor since the 1.6 cars don't have one. Figure about 40 bucks for the modification.

Now you are ready for boost parts. They are by far the cheapest portion of your build. Anybody can figure those out on their own so I won't bother.

No such thang as a cheap turbo build. well, at least one that works reliably. and doesnt blow up the car.

and as said, starting from a 1.6L car, puts you in a big disadvantage.

for a basic 150hp setup, you might be ok with stock clutch and diff for a street car, beyond this, at a minimum you need a 1.8L diff and 1.8L clutch and flywheel.

Minimum to have a working turbo car is $2000-3000, do you have this kind of budget?

I hope this isn't your only car. Mine was down for two weeks just getting the parts I needed that I didn't know I needed until I was trying to get it done.

Is there a way to get him a "noob of the week" image under his name where it says proud supporter or something

I'll take that title hahaha. I have to start somewhere right? And no it isnt my only car its staying in the garage for the winter. I often get lost in my dreams when buried in homework, and these things seem more attainable than they truly are. Guess I need to stop moonlighting and create a better plan.

thanks!

Also mines the vicious lsd, is that just as bad at handling power?

VLSD's are wear items. Considering the newest one is from 1993, essentially all VLSD's are open nowadays. They are also just as weak as 1.6 open diffs, they will break, it's a matter of when, not if.
