Engine build advice for combined daily & occasional track warrior
Hey guys,
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:
Other stuff I intend to go with:
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?
Cheers

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.

Hey Derek,
In the process of selling the pig, got no tow rig now anyway so it is a no brainer.
As for management I am probably going with a HKS F-Con iS as Danny is getting good results on his cars and they both drive/start/idle like factory management. I love full standalones on track cars but on a daily it's too much hassle.
I am going with CP pistons as I couldn't get the Wiseco pistons in 9:1 CR.
Make sure you share your experiences and I'll do the same.
Cheers

I have a fairly conservative goal and the costs were starting to blow out so I've decided instead to use a low mileage bottom end from an NA then just give it a new oil and water pump and call it a day.
I'll put my NB head on it with some ARP head studs, and fit the MBSP and sump.
Cheers
