Depends how far you push it, what supporting Mods and who / how it is mapped in, last year I bought a 350z with a blown engine, when we pulled the VQ lump out we found 5 smashed pistons
That was just running an after market ECU with a bad a map - was really quick ..................................................... until it destroyed itself!
So it's only safe if you do it right!!
Hi mate I think its the 3 pulley setup
