450Kw Asking Too Much On Standard Internals

[Paulie2256]

I read the fg f6 internals are forged somewhere and pretty sure the f6 has mahle pistons but no one has been able to confirm this.

Yes I can confirm the FG F6 pistons are Mahle.

Awesome. Do you know whether the rods are forged or not?

Hay XYZ & Paulie , I to believed that the bottom end had to be done to support 400+ safely , something I was considering doing down the track . Had a very interesting 30min talk with a well known tuner from Melbourne and he sweared black and blue that there was absolutely no difference between the fg xr6t and the f6 fg xr6t bottom end , they are identical . ( This shop has built and turned over 4000 xr6t & f6s from BA to FG ) .

This is defiantly something I would like to get a definitive answer for ..

I will try and find some pictures of the rods and pistons we pulled out of my FG F6. Pistons were Mahle.

Can't comment on the FG XR6T internals, as I am only going off what we pulled out of mine.

XYZ , that's the impression I was under . The f6 had forged pistons but the rods were the same as the xr's . I have herd this from my tuner here in Bris who has a f6 , this car has also featured in street fords .

I guess the question is are guys spending lots of $ on there fg's doing bottom ends , even buying short motors , when there really is no need to ( perhaps just doing pistons ) ?. Or is it a only a matter of time before all the guys with f6's going over 400+ start seeing bent rods ?.

Fg xr6t and f6 bottom ends have 2 different part numbers and one is about 700 more than the other an labeled HP (high power) on microcat...

I wouldn't worry about doing pistons or rods if you want to test the limits, I would worry about the oil pump letting go. A broken ring land/hole in the piston/bent rod will not normally terminate the engine. For those that don't have a clue about what to watch out for, they will continue driving an engine regardless of what noises are coming out of it but in but many cases you can catch a bent rod or stuffed piston before any damage to the block occurs. Usually its just a slight wonky idle that says something is amis. .

Just do the oil pump and see.

That's the same impression I had.. If you are in Brisbane, speak to Clinton from Profile Auto Sports he has built a few motors now including mine. He should be able to tell you the difference between the two..

That was one of the first things I got from ATOMIC , bit pricey but a lot cheeper than a whole engine .

will do mate , Its always good to talk to people with experience . Its just hard to no what to do and the path to take when one tuner will say one thing and another will say something else . ( In Bris mate , Redcliffe ) .
