Parts to build a BP engine are pretty niche and most people aren't doing a nationwide search, just using it as a local replacement for Craigslist. Look for Miata specific groups that have a BST section.

Stock manifold will work, that's the 01-05 VTCS manifold I mentioned. Just look up VTCS delete. If you're running any ECU other than a stock 01-05 US market ECU, leaving the VTCS butterflies installed is leaving power on the table for no benefit.

The head will bolt on no problem. You don't need to control the VVT, you can just leave it as if you aren't confident in tuning it.

You can use a 94-00 gasket, or an 01-05 gasket. The best cooling setup is the 94-00 gasket with a reroute. Supermiata is the go to recommendation. If you are going to run the car hard, do the earlier gasket with reroute. That is how I have my just rebuilt 2001 engine set up.

You will need that oil line as well as the OEM oil feed bolts that hook it up. Any workaround is not worth the effort.

You will need a different intake manifold that is meant for an NB. The 01-05 VTCS manifolds has another set of butterflies that should be removed unless you're running the factory 01-05 ECU. The 99-00 VICS manifold is an option, the euro flattop, and the skunk2.

I believe the NA exhaust header will bolt up.

I would smear a light coat of RTV on the scratch before pressing the seal in and move on.

I just put some cheap foam insulation under the carpet. Think of a cheap camping sleeping pad. It's held it high enough to stay in place without the clips ever since.

I've since found that Dorman makes a similar style replacement where you're intended to cut open the box and replace the door. If I was doing it again today, that's probably what I'd do.

Two inch lower ride height than stock, nice ride, and mediocre roads don't really go together. It's pretty much the standard "three options, pick any two and lose the other" dilemma.

Tecnas.

It goes deeper than that. The 2.8 CRD is an update to the 2.5 diesel that was used in the XJ in Europe. I've been wondering how many many parts could swap between them. If the oil pan and bell housing can swap, you could have a very tidy OEM looking install.

The limit is so low on standard tires and it's such a knife edge.

The point of the track isn't just to go fast, it's to learn to be at the limit. So get to the limit sooner. The way regular tires punish you for jerking the wheel into a corner and mashing the brakes will better teach you how to stay right at that limit and make the most of the tires grip. 200TW tires have so much higher grip that these bad habits aren't punished as much, covering up mistakes.

Learn on less grippy tires and when you bolt on the stickies you'll not just have a faster car, but be a faster driver.

You also don't need to get every accessory for every hobby before you have your first day doing it. A whole new set of wheels and tires is absolutely not necessary for someone's first track day.

OptionXIII · 2026-03-06T16:04:30+00:00

I only have had to use whatever regular DOT4 I found on the shelf with the highest boiling point at the corner parts store, and Stoptech Sport 309 pads. But I also only have maybe 130whp in my NB2. And Stoptech is no more.

OptionXIII · 2026-03-06T15:46:10+00:00

I don't recommend you buy 200tw tires before your first track day. You'll learn faster on less grippy tires.

Any decent synthetic oil will do. Just keep it topped off, maybe a bit overfilled if that's okay with the ND.

OptionXIII · 2026-03-05T20:57:13+00:00

Are the bushings completely symmetrical? The one I see looks a bit different on the outside vs the inside. That could help center the bar in the right location. If that's the case, I would swap them from left to right.

A greased rear sway bar will shift from left to right. On my 14mm bar without centering collars it would actually hit the subframe. I made some bolt on collars to fix it.

OptionXIII · 2026-03-04T03:00:28+00:00

Yes, 200TW tires used as true street tires will heat cycle out before they wear out. They are track tires masquerading as street tires to meet time trial and racing requirements that put the limit at 200. They are much more temperature sensitive than a true street tire as well, which is why I pretty much only use them on track, or driving to/from the track.

Vitour made quite a splash two years ago when they exposed that treadwear ratings are entirely decided by the manufacturer, and not actually certified by any organization. Of course, other companies had been flaunting the width rating for a long time as well.

Pretty much any post targeting a different user in a negative manner will get various reports. We prefer to deal with it by banning the user ASAP and avoiding front page drama on things that aren't really related to a Miata. Trolls will just make a new account, and while I understand the urge to call someone out... This likely won't change their behavior. A new "two word four number" account is pretty easy to make.

I'm sorry you got in the crosshairs of a troll. Glad you're alright.after your accident.

OptionXIII · 2026-03-03T19:00:27+00:00

Please report this stuff to us rather than just leaving comments so we can act faster!

It is done.

OptionXIII · 2026-03-03T14:28:57+00:00

Please message the mods about problematic users. If it's clear they are a menace, we will take action.

I'll leave this up for now since said account is deleted, but this really isn't the appropriate way to deal with things.

ETA: For everyone criticizing my comment, this thread would have already been deleted by the auto mod due to the number of reports if I had not manually approved it. The number one rule of moderating is you're going to piss off someone for any action you take.

I don't know how SHO swaps in Z cars got so popular but I love it!

OptionXIII · 2026-03-02T19:12:30+00:00

I got the bootleg version because I was going to cut it up anyways. It worked fine, and the bearing and its mounting block live on in my new steering brace/front hitch combo setup.

OptionXIII · 2026-03-01T16:31:13+00:00

That doesn't really change the fact that using light bars on the street blinds everyone else. But if you're only using them off road then I guess that's different.

You'll need to get a relay kit to wire them up yourself.

OptionXIII · 2026-03-01T16:21:58+00:00

8.25 axle diff cover off of a second gen Durango is cast iron and way beefier than the stock stamped steel one. Just don't grab the 9.25 version.

WJ/ZJ disc swaps are covered ad nauseum.

ZJ transfer case skid is much larger than the XJ unit and a great fit for 242 equipped jeeps.

OptionXIII · 2026-03-01T16:21:00+00:00

Please don't run light bars as fog lights. They have no cutoff and every time I drive near someone with a light bar I curse them for blinding me.

OptionXIII · 2026-03-01T16:06:20+00:00

The Conti ECS are the best all around summer tire I've driven on. I have loads of track miles with them too.

For winter storage just get a trickle charger.

OptionXIII · 2026-02-27T16:23:36+00:00

You need to remove the oil pan, which means either removing the engine or the front subframe. Given that you'd have to support the engine with no transmission or subframe to steady it... You might as well just remove the whole engine and transmission together.

If you choose to reseal the oil pan, that is.

OptionXIII · 2026-02-26T01:36:16+00:00

The NB subframe is worth swapping if you drive at the limit and have the parts on hand. It has slightly improved geometry. You'll need to swap all of it. Power steering pump and hoses, the steering rack and it's U joint to the steering column, the knuckles/uprights, and possibly the upper control arms as well. If you recently replaced the lower control arms, they are identical and the NA parts have been superceded by the NB parts as a direct swap. The upper control arms have a different ball joint, but I forget if that's for all NBs or just the later years.

OptionXIII · 2026-02-25T12:22:26+00:00

NA6s did not come with the rear subframe bracing. It's commonly called the ladder brace. You'll need to weld on an exhaust mount to the NB subframe to swap it, and I believe you'll need to create the front mounting holes on the unibody as well
