Would the 99 pump be good for a 95 block?

I think they have the same pump, a search will confirm if that's true. Or mazda's part number for each year.

That is the correct oil pump. The 99/00 oil pump is now the part for all 90-00 miata's. You will need to order 2 more things for that pump though. This plug is required for the pump. You just knock it into the hole in the oil pump. It will make perfect sense once you have them in your hand. You will also need the o-ring for the oil pump. I don't know if it comes with the oil pump or you have to order separately. Give Priority Mazda a call and ask for Tommy. He will hook you up with everything you need.

Amazon does not say it fits with my 94, so not sure if it is the correct one also. Also not sure if it will require the plug or not. I would personally cancel the order and order the Mazda one. If you give Tommy a call he could probably get it out today.

I bought the cheapest ones I could find on eBay. Here is a link to them. No clue how they work, as I have not used the motor that they are in yet.

Welcome to owning a turbo miata, makes a horrible DD, unless you have a backup car, then it will always work perfectly.

I picked up my first DD about a year after turboing my miata.

My first DD was a 98 Integra GSR hatch. Had zero desire to mod it. Then I moved on to a 93 miata with 300k miles. Then I bought my Mazda2. I have done nothing buy regular maintenance to any of those vehicle and have had zero desire to mod them. I even have lowering spring for my Mazda2 in the garage that I have not installed yet.

Not sarcasm here but do you guys honestly have that many problems with street cars? I know people like soviet, fae, lars, and all the other coolsters with big numbers obviously don't daily their cars but are stock motor builds that unreliable?

It is random **** that pops up that causes issues. I drove my 94 with a Begi setup as my DD for well over a year with nothing major going wrong. Lots of small minor inconveniences though. It just got to the point where I wanted to be able to have the car down longer then a weekend for work.

It is like your engine randomly loosing oil pressure. It should not have happened, but it did.

I daily drove my MiataTurbo for two years (summer only) before putting it away last fall. I rarely had issues that brought the car down for long but I agree that having a backup daily is a huge bonus. I would have hated to be forced to fix my prior issues in an evening or over a weekend. It would have led to shittier modifications or repairs.

Now I am a little on the extreme side. I bought myself a Fiesta ST so my Miata hasn't been on the road since February when I got it out of storage. When you have a fun daily it makes it less painful when your Miata is down for upgrades. I think the Fiesta is making it a little too easy to go without my Miata right now, so in compensation I am going even more nuts with the Miata than I would have.

When done right they can be very reliable. When thrown together they can be a mess.

Mine hasn't been perfect (apart now for a turbo replacement/upgrade) but given the powerlevel I run this car at every day, it's pretty reliable. I daily mine.

The key to a reliable turbo Miata is to build it right, debug it, tune it, and then STOP ******* WITH IT.

I enjoy tinkering with it, so mine is often in semi-incomplete states.

I had the odd hose go, only because they were 20 years old and I thought I didn't need to replace them. Besides the front main seal the new motor has been pretty "reliable". It just sucks that this happened, someone has a 140k 1990 for sale for like 600 bucks, sounds tempting right now

Before I start a new thread I figured I'd pop this question here first.

Tacotaco t3, manifold to turbo hardware. I've been using some short grade 8.8 bolts. Does any one know what would be acceptable to replace these with stud wise? The ones it came with were too short, I ordered 4 begi ones for the head to manifold so I can stop using bolts in that area. I believe the thread is m10x1.5
