i figured this would be a good discussion to have here, as there are many more people here who truly abuse their turbo bp's compared to the fwd crowd.
i cooked my motor recently. damage = i melted the edge of the piston near the valve reliefs in cyl 4. i can see the top ring with my buddies borescope :(. i'm thinking this was probably caused by one injector being a little down on flow... we'll see
i can do one of three things:
1. rebuild motor with forged pistons. its still running fine otherwise, no knocking and it doesnt even smoke. hell it still runs low 12's. i figure this would be pretty straightforward, however it would probably cost just as much as my other options. i dont "know anyone" who can do machine work or assembly work like this.
2. replace with a built BP long block. my friend is selling his built BP but he used a small nose crank engine :(. i could buy his motor, swap out the crank and oil pump, and drop it in. the motor has generic h-beams, wiseco 8.5:1 pistons, arp head/main studs, OEM mazda bearings, etc. solid motor and should take whatever i can throw at it.
3. replace with another GTR engine. if you don't know what the GTR is please click here
for some info. for the same price as #2 i can get a complete (used) GTR engine from another friend. it will come with the turbo, manifolds, everything. if i dont screw up my damn settings again it should last a long time. plus, i can sell some spares to recoup some money since i already have 2 spare turbos, and who keeps spare manifolds?
what would you do, mt.net?
