How To Do an EXHINTAKE Cam Swap On a Miata! [Project 2SJ Ep10]

[@TheCarPassionChannel]

Sup guys, one thing I breezed over a bit in the video is that this modification uses a 99-00 exhaust cam, and can be done to 1.8L Miata engines 1994 - 2000. A 94-97 exhaust cam can also be used, but it's not quite as aggressive as the 99-00 cam. 1.8L and 1.6L parts are not cross compatible as they have different cylinder spacing. The 01-05 engines use a special intake cam for VVT which can't be swapped out for a normal cam. Unfortunately we don't have the 1.6L NB in the U.S. so maybe someone in the comments can speak on that information. As for the BP5A/MSM intake cam swap, yes it's a drop-in part so obviously it's easier than the exhintake mod. But you're looking at $25 vs $300 for about the same gains, the choice is yours!

[@Nasonix2]

As far as I understand, you can use any 1.8l exhaust cam for it though, not only a 99-00 one. Like I have a 99-00 head (bp4w) And if I took my exhaust cam from my '95, it would still be a ex/intake mod. Am I wrong?

[@JamesChurchill3]

My 2001 1.6 doesn't have VVT, does this mean it's still compatible?

[@TheCarPassionChannel]

@@Nasonix2 Yes, but the BP05 exhaust cam is less aggressive than the BP4W/BP6D so if you're going to do the work, might as well get the biggest profile you can.

[@TheCarPassionChannel]

@@JamesChurchill3 Sorry I'm not very familiar with 1.6L NB cars as we don't have them in the U.S. You'll have to do some research!

A- it makes me furious that you don’t get more views. B- cannot wait for the dyno of this.

[@jaguarjay13]

I assume this could be an important question for some: Does this effect the non-interference design of the engine? Will the valves be able to hit the piston with the extra lift?

[@TheCarPassionChannel]

No - as long as the head is not shaved, and the head gasket is stock thickness, this will not create any interference.

[@adri1leusha]

Amazing content! Thank's for all this precious intel. I was wondering, while watching; Is there a way to not drill the cam gear, and instead change timing marks on the gear? If you know the angle needed you can take it into account when putting the timing belt, and set your timing accordingly. Unless there's something else I don't know. Maybe if you try to do that you fall between gear teeth and not get the right angle?

Yes! This is what I wanna see!

[@connorplaksin1821]

@@shrimp562 I’m pretty sure he’s referring to an European Spec NB 1.6. They were rated at 90HP and had a little CAS sensor on the front of the valve cover like its 1.8 counterpart. No physical connection to either of the camshafts like the NA. So I’m pretty sure this mod is perfectly possible on his car.

Greg by doing this morning will it make the motor a interference motor or will it still be a non-interference motor 🤔

[@papiloran]

On my 1.8 na it have a small idle cam sound and more top end. I could do second gear burnout more easy.

[@natereed3409]

Search youtube channel "conrad" for his ex-intake mod. He didn't have to drill a new hole in the cam gear. Simply figured out how many teeth he needed to rotate the cam and then put on the timing belt. Basically you make your own new intake and exhaust alignment marks. EDIT I noticed his video says for 1.6....wondering now if it would apply to 1.8 cars as well

Hey man all I have is a hsk intake and the same exhaust as you have in my 1.8 02 nb, and when I lift at like 4,000 rpm it will shoot flames, completely stock car otherwise, why is this? Of course I like it I’m just curious :)

[@patrickfargie1146]

[@GuernB2]

I feel like Miata Dad made this video just for me. Thanks Dad. I love you too Also I'm curious how the Ex-Intake compares to the mazdaspeed intake cam. I know the Ex-Intake has slightly more lift but not much else.

[@codycolton5740]

i’m having trouble finding oem camshafts around me. is there any advice you can give me to find them, on marketplace i can’t find any part out engines. also if i put a bigger camshaft in, do i need a tune. i still have a stock ecu.

[@hesperidesbell4643]

I have 2 stock cames i need reground. What would you recommend for a good chop?

[@DarkDMD]

I know this is an old video, but I was hoping you could shoot me a reference to actualy dyno numbers for gains off of this upgrade? Searching forums just results in people heckling each other about this since circa 2004!

[@KbrentYT]

Miata Dad! Thanks for all the great vids and info. Question: as I upgrade my 95 1.8L, I'm swapping cylinder heads for a '00 BP-4W. Do you know offhand if the BP - 05 exhaust cam will fit properly as an intake cam in the BP - 4W head. I haven't received the new head to take measurements myself and wondered if you knew. Thanks!

[@TheCarPassionChannel]

Yes it will, and it's the same exact procedure as shown in this video. The BP05 exhaust cam is slightly less aggressive than the BP4W exhaust cam, but is still a slight upgrade over the intake cam

[@paulvanderveen1986]

can i use the 1.6l exhaust cam of a NB? (EU) or is it only the 1.8... so i have measured the intake cam vs the exhaust cam lift: 1mm more lift in the exhaust side. the 1.6 (EU/JP 1999) the length is the same as the intake cam

[@hesperidesbell4643]

I know this is for the 1.8, but would it be possible to do on a 1.6 using the exhaust cam from a 1.6?

[@cafemotorsports]

Kainjection used to sell a adjustable sproket already drill for this mod

[@leoroehr98]

Hello, I have a lot of questions. I’m looking to shave my head 1mm (.040) and to do this exintake swap. Is a aftermarket ecu and tune needed to be a daily? Or can I run it how it is

[@Chimera6297]

you should do a dyno chart comparison of the 14 degree timing advance vs. the 10 degree advance I've never seen the data accurately represented, everybody just says "well, it FEELS faster"

[@TheCarPassionChannel]

On the NB it's a little more tricky, you have to install one of those adjustable crank position sensor mounts, kinda whack. However, Most of the gains going from the stock ECU to the tuned ME442 were in the ignition timing. (113whp -> 120whp)

[@GianucaSimo]

Hi there i actuallt got the CAS attached to the intake side (b6 things) i should use a bp exh cam like and fit the cas without problems right?
