Well i mean more like.... $1100 gets you motors that don't suck. Instead of a BP.

Miata tax is real.

They work. If you are looking for a fun street toy that uses motors most people throw out and don't want to make a ton of power, it's fine. If you want anything more than that, 1.8 swap (do as I say, not as I do, says the 1.6 turbo owner)

It's not the displacement, it's the head design. The 1.6 heads are archaic.

This is the main reason I finally decided to stick with the 1.6. I can learn engine refreshing, tuning, all kinds of things, and just blow up engines people will litterally give me to get them out of their garage. I have two long block, a really nice low miles short block (with a slightly bent rod) and a whole, running, 91 automatic that I have collected. Total outlay has been less than $200, and most of that was fuel for the van and the dolly rental to get the auto car.

Ive seen this reason posted a hundred times before.

replacing engines is not free (however cheap) and not fun to do.

the 1.6 serves no advantage to "learn" on.


If you want to use the 1.6, thats fine. but dont put one dime into it, IMO. "refreshing" an engine is a slippery slope and even a bare bones, OEM rebuild is in the $1200 range all said and done.

If you are doing it right, sure! I am gonna get a head gasket, couple other seals, pick the best condition pistons, bearings, block, and head, measure clearances, ball hone, cheap OEM type rings, ebay rods and slap it together. Maybe lap the valves in with a drill. This is my tinker car. Replacing engines is part of the fun.

Sorry, for the misunderstanding, I think this, too.You can even get a nice BMW engine for half of that over here in Europe.

Miata tax seems to be a US thing. I could pick up an NB2 tomorrow, lots of stuff is missing, but the complete driveline is there.
VVT engine, 6 speed, torsen - not even 1000€. It's crazy...

Can you link this thread? I couldn't find anything useful.

Why not? If x_25 enjoys tinkering, let him tinker. Though I get where you're coming from. If I pop my 1.6 it's getting a 1.8, and I wouldn't spend the money to do a built 1.6.

because he is a broke college student. throwing money at the obvious disadvantaged 1.6 (just to learn) is fiscally irresponsible for a person without a pile of expendable income.

Just learn on a better platform. Entry level computer classes dont have you start on a Tandy, do they? I mean, its a computer sooo...its LEARNING! lol


IMO, if you intend to ever upgrade to a 1.8, then dont open up a 1.6 for any reason that involves exchanging money with another individual. If you want to turbo a stock 1.6 to "learn how" then do that, but dont open it up.

Actually, I finished college and bought a house and have some expendable income. I have spent the last 3 years watching for good deals on 1.8s that are local. I am not spending $800 on a motor that I am going to need to refresh before I even drop it in (cheapest I found was a VVT at a junk yard for $650, turned out it had rod knock). All the 1.8s and good miatas have been eaten up by the drift kids in this area.

As far as why bother with the refresh, the 1.6 in my car is getting long in the tooth. Been semi trying to kill it for 4 years now. High timing advance N/A on 87, track days, autocross, all kinds of things like that. Then supercharged for 2 years, again, high timing advance, never checked it even with det cans. Now it's turbo abd making 190 to the wheels. Compression is getting low, have some blow by, main seal is shot and the crank sprocket is welded on (done by PO). It's time for a new engine.

As far as dropping money, $240 for rods, gaskets, rings, maybe bearings, then a dingle berry hone and some valve lapping compound. Figure $500-600 all in for a freshish engine ready for everything a TD04-13T can throw at it.

This picture will show you the answer to that question.

Everything we need to know. Ultimately the 1.6L makes more power at 6400rpm than the 1.8L. Ignore all other alternative facts
