Yup, I couldn’t agree more with that. In 90 percent of cases a turbo 1.6 will be nearly as fun as a 1.8, and then once it blows its worth the upgrade since just getting a manifold isn’t too expensive and you’ll already have the rest of the kit which would only need slight modification
my 1.8 came with the exhaust manifold and downpipe, plus a whole wiring harness and ECU that I didn't use lol when I pulled the valve cover off it, it looked clean as FRICKIN HECK
Nice video! I do feel like you left out a few points on why people might go for a 1.6 over a 1.8. The 1.6 is a lower compression engine, meaning it’s (from what I’ve heard) safer for boost. The 1.6 in the Miata came from the 323 gtx, which was turbocharged. So to some extent the 1.6 is built to be boosted! I think that’s where the argument from the 1.6 comes from. Not necessarily because it’s “more powerful” than the 1.8 (it’s not), but because it’s more reliable
Those are common misconceptions! The 1.6 actually has a higher compression ratio than NA 1.8s. It’s 9.4:1 vs 9:1. Later 1.8s are ever so slightly higher, but not enough to make a difference. The argument for the 1.6 coming from the 323 GTX isn’t a good one because that motor had stronger rods which the Miatas didn’t get, and that’s where it’s advantage comes from. The rest of the reasons that the GTX motor is good for boost (oiling) is carried over to both the 1.6 and the 1.8. I hope this helps and thanks for stopping by!
love your videos, you're very knowledgable and an all around good guy. An na 5 cylinder volvo is 2.4 and turboed is 2.3 volvo made the cylinders smaller ,hense thicker walls. for heat dissipation. So I believe the 1.6 guys say it is better for boost, because of the same theory. thicker walls stronger and so on. but building what you have and all your other reasons you gave are very solid. Keep them coming, those videos heck ya!!! love ya Cash
While I get the logic behind that I'm not sure that it applies to Miatas. The 1.6 and 1.8L have different cylinder spacing and are a completely different block. The 1.8L is known to be safely overbored more than a 1.6 before problems, making me think that it has thicker cylinder walls. I'd love to see some data that backs up that the 1.6L has thicker walls and is better for boost, but I really don't believe it's the case. Once again thanks for your comments!
I agree with all you say. I have a standard torquey 1.8 NB and 2 x BBR Turbo 1.6 NA's. 150bhp & 204bhp. I much prefer the 1.6 engine and it's revvy nature. Diffs - yes essential over 170bhp. I blew 2 in my 204bhp car. BBR told me the NA diff is only designed for 170bhp. The car now has 1.8 flywheel & clutch, 6 speed 'box, LSD and 1.8 wheels & brakes. It's too fast for UK driving [and a 76 year old who still thinks he's 18] so it's used for continental trips. I think the NB is a much better 'car' but the NA gives me more smiles per mile.
Both 1.6L and 1.8L engines are great engines. I plan to buy my second NA Miata soon, and I will get whichever NA I find a good example of... I'm not interested in boost! I just like winding it out in the gears!
I'd like to add that if you own a 1.6L in california. You can pass smog with an aftermarket ECU. We have a thing called the sniffer test. A lot of turbo cars have megasquirt which cant use OBD2 so thats an automatic fail for smog test. It really up to the owner. Do you want to pay $200-$300 for an illegal smog pass? or just pay $40 for a normal smog test. In short, if you want to turbo your miata and still pass smog with an aftermarket ECU, get an older miata(1990-1993) these only came with 1.6.
I 1.8 swapped because my 1.6 blew. it had 289,122 miles on it so it was about time for it to go I must say tho, the swap is not too bad. you can keep your ECU and just use the old throttle body with an adapter plate I don't remember what else I had to do, but I got some of the parts from the Flyin Miata swap kit and it made it all super easy. especially for someone like me who barely even knew anything about cars. I didn't use the crimp connections tho I just twisted the wires together and heat shrinked em, and it hasn't failed me to this day. overall I rate it 10/10 probably the easiest engine swap you can do. but get the most out of your 1.6 before you swap the engine they're both solid built engines that can handle abuse. and that's really all you need
I believe all manual 1.8s were equipped with torsen differentials as well, while no 1.6s came with torsens, only viscious differentials or open differentials
good video, thanks. It is legal to put a turbo in your miata where you live? lucky guy. I am looking to know which NB i will take between a 1.8 no-vvt and a 1.8 with vvt. I already have a 1.6 without vvt of course, i find it funny, and love revving it. But i am wondering if a LSD could improve my overall experience (not interested in drift) and if a 1.8 could really improve my feeling in general while driving ? maybe then i could get some modifications on it as cams or others, but nothing big, maybe having 160hp should be better (currently on 110 with mine) what do you think?? keep it up!
I think people say 1.6 is better than 1.8 for boost because the 1.6 is a sturdy block from ford, and was in the 323 as a turbocharged version. So it's known to handle boost. I'm not sure about the origins of the 1.8...
@@CashedOutCars No problem. I am the proud owner of a 1999 NB Miata showroom condition. Still has the working Bose Cassette tape player. I researched them before I bought mine. I think after 2000, the NB 1.8's also had VVT which boosted the HP as well but the first year NB's like mine did not. Keep making the videos!
Awesome, I’m looking for an NB myself right now. I should mention that it looms like solid lifters started with the NB, so not all 1.8s will have them. I also should have mentioned when VVT started in the video. Thanks for pointing that out, enjoy your Miata!
If I could have K swapped it for $1,050 I’d have been all over that! It’s not a realistic budget though. Stay tuned for some potential K swap stuff on the channel in the future👀
The 1.8L Mazda engineers' featured a forged crankshaft, piston oil squirters, a structural aluminium oil pan with cooling fins. Doesn’t this make the 1.8L stronger than the 1.6L ?
1.6s have oil squirters too! You'll be blowing 5 speeds well before you have crankshaft issues with either car. I'm not sure about oil pans but my 1.6 has small fins on it and is also aluminum
@@joel-nr2dw so if i would get a 90hp 1.6 i could change the camshafts and maybe fuel injectors to gain about the same power? Because 90hp are safer with abs and strut bars and stuff, and they are definitely cheaper than the 1.8 in my country
@@playcer8388 absolutely, I'd do my own research, here are a few reddit threads which explain lots more about the topic with a lot more depth. The best course of action I'd say is swapping in a 1.8 but I can imagine that would be more difficult than obtaining a different camshaft
Looking at a Clean NA 1997 Miata manual with 97k garage kept its whole life new timing belt and oil change service records since bought also new hypergram rims and new tires worth 6k?
is putting on a turbo on a 1.8 liter harder than a 1.6? like say if you get a 1.8 liter miata and you want to turbo it. can you just take off the turbo on your 1.6 liter and just do the same process you did on the 1.8?
Yeah it’ll be the same process! Neither is particularly harder than the other. The difference will be in manifold, a 1.6 manifold won’t fit a 1.8. Also, depending on what you use for a motor, you may need a different wiring harness or ECU setup if you’re doing a swap
There's a small difference in the way you get oil into the turbo because the 1.8 engines don't have a convenient unused high pressure oil feed like the 1.6, but it's a very small difference and it doesn't necessarily make it harder to turbocharge
A lot of people think that but there’s really no reason why, I can’t tell if you’re trolling after watching the video though😂they have the same rods, so they can both make about the same amount of power before problems!
@@JavierVillalobos but with a higher compression ratio still comes less power. Plus a higher compression ratio means easier knock with advanced timing or a turbo
@@CashedOutCars In any case, they are all fun to drive, here in Europe we have a lot of mx-5 clubs and the 30th anniversary of those clubs is coming up in the next few years, we wil have meetings throughout Europe. Have fun, drive safe!
They last 300k easy if you change oil on time. 200k Miatas can be bought for cheap and their reliability is still a given. My 200k Miata has 190psi on all 4 cylinders on a compression test

Pretty much, Boost your 1.6 until it blows. Then get an 1.8 manifold and 1.8 engine and do it all over again but better.
