Engine build advice for combined daily & occasional track warrior
I recently sold my dedicated track pig as I wasn't really getting much use from it. I am now focusing on building a fun boosted daily that can handle the occasional track day (probably around 6-10 days per year in reality).
The car is a 1998 NB. The main goals here are good economy and reliability. To keep things fairly reliable I am making use of a lot of factory Mazda bits.
Here is what I already have for the new build:
- 1994 NA 1800 block with the oil feed port
- 2002 NB sump + MBSP
- 1998 NB crank + complete head
- 2004 MSM/SE turbo manifold, exhaust, lines, water pump inlet, AEM intake + turbo fitted with a 15T compressor wheel
- TODA chromoly flywheel
- 2002 6 speed gearbox
- 40mm alloy radiator with good ducting
Other stuff I intend to go with:
- Wiseco 9:1 pistons
- Eagle rods
- VVT oil pump
- Coolant reroute
- Welded -10 drain fitting on sump
- Everything balanced
I intend to run the turbo at approx 1 bar of boost, maybe up to 250hp at the wheels.
Do you think this is a good recipe for a rock solid daily including driving it quite firmly at the track? Anyone got any long term stories regarding forged pistons in a daily?
Apart from properly sorted engine management, injectors and clutch, can you think of anything I may want to consider?
