im new to the whole rotary business so ive been doing some reading. am i correct to assume that if you put a high flow oil pump, higher oil pressure, upgraded oil cooler, higher capacity oil filter, upgraded radiator, and high flow water pump on the series 1 engine it would last longer? perhaps not as long as a series 2 since they have an additional oiler but is that not the gist of what mazda did to ensure a longer life span for their prized renesis?

 

To my knowledge, there isn't a high flow oil pump. There is a mod that will provide a higher oil pressure.
The automatic transmission cars came with one oil cooler. The manual's with two. Unless you are road racing the car, there shouldn't be a need to upgrade.
Higher cap oil filter, upgraded radiator & high flow water pump not necessary, unless you are racing.
Some have gone way beyond 100K miles before a rebuild is required. Others have had problems. Any mod you make to the car will not be as rigoristly tested as the car was delivered by Mazda. The only thing that I would suggest for a normal street driven car is to move to a heavier than suggested weight of oil and to consider pre-mixing (look it up) to increase the longevity of the engine.

 

and make sure your temperatures are under control

That's a good start. Unlike zillions of noobs here their first questions was "HOW DO I DO THIS? I M TOO LAZY TO REAd/SEARCH"


there is no higher flow oil pump. what you can try is go with Mazda's or 3rd party's dry sump oil system. but the system itself will cost more than the engine itself so its not worth it.

Its doable. time consuming tho, cuz u have to take the oil pan (wet sump for austie friends) off to remove/install the stock regulator. make sure u have a 26mm wrench/socket before you start.

This is not 100% necessary. You can use a bigger cooler at stock location.

This is easy, but hard if you have oil sandwich adapter installed.

keep in mind a bigger radiator will NOT lower your existing temp. what it will do is it will keep your car at certain temperature for longer.

If u do a lot of 6.5K or more rpm runs (racing application), then u need it. other wise hmm ...

This engine is a hit or miss from factory. it really depends on your luck. Im too lazy to explain it

well, with the increased OMP volume, it is "ok" but of course stock for stock a S2 should last longer than S1. but if the S1 owners premix from day one I don't see any problem with S1.

 

yeah i just read up on premixing, im def doing that. thanks for the help guys.
