Upgrading from my 310rwkw 300zx z32!The BA has larger injectors, manifold, td04z turbo, 2.5" zorst, and few other things.My question is, how much power can stock pistons/rod hold up? (depending on the tune which AVO will do). Can I get 350rwkw safley? less? more???I shall be posting up my new car and mods etc once its all ready to go and after a tune.Cheers!(Welcome myself to the XR6T world!!! FINALLY!!!)

Jam the boost in hard early, mmay go bang. Bit of a lottery really.You play, be prepared to payBTW Link to comment Share on other sites More sharing options...

Posted 17/07/09 06:28 PM Author Share Posted 17/07/09 06:28 PM when z32 cost 3k per engine pull and 12k for rebuilds, I can deal with 5k builds lol...I just met someone tonight who has their BA running flat 10s on stock internals pushing 375rwkw. Has 2 sp powerglide and semi slicks. Pump fuel.Springy motors I think it was. Well I shall see what AVO say about stock internals and keep askign around.Are there any straight fit piston and rods (set?) that slip right into block withouth needing any head / block work etc? Like a straight swap to strengthen em to have no problems with 400rwkw? Like newer model xrt6 typhoons or somethgin aftermarket? Link to comment Share on other sites More sharing options...

Last I heard BF F6 bottom ends were going between 2200-$3000, can anyone confirm this? Link to comment Share on other sites More sharing options...
