[Maxxr6T]

Gday could someone point me in the right direction please 're rods and pistons,it's a bf turbo,60 pound injectors,x4 tuner,4 inch dumpy into high flow cat 3.5 inch system,bigger intercooler, zf 6 speed. Any help would be appreciated cheers

they're in your engine block

Seriously that's a pretty vague line of text

I guessing you want to work out what your stock donk can handle and/or what do others recommend for upgrade, at least try a search in the engine workshop section, massive info in there

Or if you're after something specific then the blokes in the know are going to ask what build date, km done, power you're making etc etc

If it's post 06/06 your gunna run out of injector before you will need pistons/rods

Sorry for not being clear, I just wanted some advice about new conrods and pistons, all the other stuff I had listed is all ready on the car, to cut a long story short it suddenly got a rattle and the mechanic wanted $6200 and my motor because he thought it had a broken conrod, I ended up pulling the motor out and found it had jumped a tooth on the timing and the valves hitting the pistons was the rattle, the car is a bf turbo Oct 05 82000km. I thought it might be a good idea to put some better rods and pistons in to handle the rest of the mods, don't know what it's running power wise but I would say a fair bit it's running the 16psi tune, might get new cams aswell. Cheers

You can't just fit rods and pistons. You need to have it bored to suit the pistons and while your there skim the block back flat ready for your skimmed head and new head gasket.

And with rods it's best to balance up the rotating system. Need to get the rods fitted to your pistons as well.

As for brands. Spool make a solid rod for a cheap price. Pistons is how far your budget allows. Ross is a strong cheap option or cp, or mahle, or a set of tbre customs is a nice piston.

Don't forget oil pump gears, atomic timing chain, lower sprocket, tensioner, new guides, arp head studs, main studs while your there.

Thanks for the advice gaz, I thought I could get standard size pistons, the stuff you had listed I will get also and flexplate, I was looking at the spool rods and Ross pistons can get them for $1450

Need to get the correct bore to wall clearance with a forged piston so it's best to bore to suit. Yeah they're pretty cheap. Did you buy a new motor? What are you doing for bearings etc?

Same motor it was running like a dream, don't know why it skipped a tooth I've never had it bouncing off the limiter, I had a ba turbo for four years and not a drama, that only had 10 psi and a uni chip felt sluggish compared to this one. I'm going to get bearings aswell.
