thank's for puting all this info out! I've had a 1.6 na for a few years now, and recently came upon a decent 1.8vvt NB donor. I definitly plan on swapping someday, and these videos are a goldmine of information! I knew that spark was bonded on earlier engine, but I didn't know it was also the case for injectors! doesn't that waste fuel?!

@NappMotorsports Ай бұрын

No it just sends half the fuel required twice.

Outstanding mate... great content, great resource and I'm impressed with the quality of both your work and your YT productions. P.S. What ever happened to the KSwap Turbo build? Last I saw it was running but not 100% sorted... then I saw a KMiata video and your build was referenced as a partnership 'thing'.

wildly off topic question. but you mentioned the IACV, and it got me thinking. i own a bone stock na6 and the IACV under the throttle body is bad. new ones are like $600-$700. is there a way to swap to a nb throttle body and IACV. does it take any wiring? will the na ecu be affected buy a different throttle body and IACV. love the video btw.

One small thing I noticed is that the 1.6 and VVT idle valves use the same terminal in the connector. Just depin the 1.6 connector and pin the wires into the new connector body

Do you use a specific Tesa tape? I bought some before, but mine has more of a sheen to it, and unless it's just the camera, yours looks more cloth like?

No need to change injector wiring harness on na8c right? It is already capable of sequential from stock, or am i wrong?

You are correct. And weirdly the 93 with California emissions is also sequential.

Shot in the dark, has anyone made the radium fuel rail work w/ an OEM NB intake of some sort? The skunk2 has so much clearance. My squaretop...not so much. I have an 99/00 rail + 90-93 FPR and all that jazz but man the radium setup is clean.

@NappMotorsports Ай бұрын

I haven’t tried it, but you could probably fit the rail no problem. It’s the regulator that you’d struggle with. You could do a remote regulator.

How much of a difference does VVT make when compared to the standard 1.8? Everyone is making the jump, but others are still making huge numbers. Is there a video of the actual difference between the two?

@NappMotorsports Ай бұрын

I have a video comparing them a few videos back. VVT won’t make more peak power, but it supplies more low end torque without sacrificing top end.

@eric1138 Ай бұрын

@@NappMotorsports Really? I was under the impression that the NA 1.8 makes 127 hp and the VVT motors make 142. Or do you mean compared to the BP4W 1.8 in which case the difference is indeed negligible?

How about tachometer wiring for vvt swap on a 94?

Your ecu (Megasquirt and Beer Money) should send a tach out signal already with no wiring changes.

Should be a direct bolt on. You’ll just have to drain and recharge the AC

@alphagurder5828 2 ай бұрын

Is the skunk 2 throttle body bad? Or is it just the case that it doesn't provide extra quality/performance over a generic throttle body

@NappMotorsports Ай бұрын

Skunk2 throttle bodies are awful. They snap at the spring. There is a benefit to a larger throttle body, but you should just get the eBay 64mm one instead of skunk2. Less than half the cost and it’s better, just remove the blade screws one at a time and put some red loctite on them and reinstall.

How has the 10lbs flywheel done with AC? I noticed that with my 14lbs ACT flywheel, my AC at idle isn't the best, but once I get back up to speed it's fine. I have had to convert to r134 since the old r12 leaked out unfortunately. EDIT: You don't have to use a 1.8 throttle cable if you have an FM 1.8 swap throttle cable bracket. I know it works, because that's what I have on my VVT NA6!

So I purchased a 92 miata from an insurance auction and came to realize that its been engine swapped with a 1.8 vvt. The oddidty to me is that the vvt system appears to be dissabled. Why would this be done? How can i get it working properly? Edit to add info: the wiring harness appears to be from NB2 and has the pigtails for the vvt acuator and cam senor but both are left unplugged and are zip tied out of the way. It also seems to be the NB2 ECU that has been mounted behind the passenger seat. I wish i could get ahold of the previous owner to ask questions but the insurance company will not release their name. Also, I know the car ran when it was written off and i have moved it around my yard and seems to run okay but the rad is smashed so I cant get a good test drive. My intent is to run this power train in my 93LE.

@@NappMotorsports right? I do plan on making it work and the first step is just to plug it all in and she what she does but it baffles me that it was disconnected at all.
