Can I start my car with the radiator cap off?
Start with a cold engine. Remove the radiator cap and fill it to the recommended level with a 50/50 mixture of antifreeze and water. Make sure any auxiliary tanks are also at the proper cold fill level. With the radiator cap off, start the engine.
Where do you put coolant in a Miata?
The coolant should be at full in the radiator and between the FULL and LOW marks on the coolant reservoir when the engine is cool. If it is at or near LOW, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to FULL.
What coolant does Miata take?
Prestone 50/50 Coolant/Antifreeze.
Where does the power come from in a Mazda BP?
Blueprinting – N/A power inside the block comes from virtually every mechanical interface or area that intake charge contacts. Thus why a pro level N/A race engine is not cheap. Blueprinting, by definition is simply building to a specific tolerance within OEM guidelines.
Can you use stock gears on a n / a Mazda BP engine?
For N/A builds below 7000rpm, stock gears are fine. Low power <7000rpm <190whp F/I or N/A <7400rpm, you can get away with stock gears but have no “insurance”.
What’s the best lifter for a Mazda supermiata?
For any engine that will either have more than .400 lift or see sustained >7500 rpm, we recommend SUB (Shim Under Bucket) lifters. They weigh a bunch less and will retain the lash cap even with the most extreme cam grinds. The reduced weight improves valve seat life and increases over rev protection.
What kind of thrust bearing does a Mazda BP use?
The NB2 engines (01-05) use a wider thrust bearing. ACL only makes a thrust bearing for the 94-00 BP’s so find an alternate for that one. Pistons – The OEM pistons can be made to survive for short periods above 8000 but are limited to about 7500 if you expect them to last 100hrs.
