#4305 of 4364 Re: 82K mi on '04 Miata MazdaSpeed - Timing Belt question [toydriver1]
May 12, 2008 (8:35 am)
I just had mine changed this weekend. I was overdue - 76k miles.
They used a whole timing belt kit and did the water pump, too.
The job got a bit pricey but it's the first major expense I've had in 8 years, so I can't complain.
On a bum note, I had my timing advanced to 14 degrees BTDC, and they set it back to stock 10 degrees. Would you believe I feel the difference?
I gotta find those old instructions so I can advance the timing again.

I have the same problem with my '93 Miata. It has 60,000 mile on the clock and I only drive 3 or 4 thousand miles a year so I figure the belt might last until 2018, when the car will be 25 years old. I searched the internet and couldn't find a case of the belt failing in less than 90,000 miles . . . but age may also play a part.
If it fails before the rest of the car I will report on how many miles (or years) the belt actually lasted. I understand it is a non-interference engine so a broken belt won't trash the pistons and valves.

Yeah, it won't do any harm but you may end up stranded.
I advanced the timing, and it fixed the power loss issue.
They had it set to 1 degree BTDC, it's supposed to be 10 degrees!
I advanced it more than stock to 14 degrees. Runs like a champ now.
#4308 of 4364 RX-7 engine swap
Jun 26, 2008 (12:28 pm)
Due to the fact that my '99 miata's engine has died to the point of a rebuild, I have opted to install an R1 engine and transmission into it. However, I do not have the resources or the time. Does anyone know of a shop who could do this in the Alabama area. I'm willing to travel to Georgia and Florida.

Whats an RI engine?
You should go to www.miata.net, a lot more readers there that know a lot about their cars.

reading my post, I guess it was a little confusing. I was talking about the engine out of an RX-7 R1, which is the model type. kind of like you have your gt's, r/t's and slt's. It's a twin turbo on '93 models.

I googled "rotary engine Miata" a year or so ago and got a lot of information about a few attempts at doing what you are thinking about.
#4312 of 4364 Oil Pressure
Jul 20, 2008 (10:10 am)
I have a 1990 MX5 with a new engine. 2500 miles. The oil pressure guage does not show oil pressure till about 2000 rpm then at best only slightly. I know it must be better or I would have motor problem by now. Previous owner installed new motor so I don't know much about the work done. Car runs and performs well. Need a new sender? What should the pressure register?

Well, the 1990-1994 models had real gauges that actually measure oil pressure, not just a dummy gauge like the later ones.
Mine reads low until I rev the engine, but not zero, just low. It jumps up when the engine revs, then stays pretty steady and increases slightly with high rpms.
