The whole heads getting re done, I’ve sourced a low k na head so I’ll need new exhaust valaves . Happy with keeping it with Stock ford ones but they are close to $100 each , or xr6t development sell a set for a couple hundred.

Chasing a new set of exhaust valves for my new head . What is a good aftermarket brand to suit my turbo application in my Barra .

Need some knowledge. I’ve got a 2005 bf turbo , im looking at changing the cylinder head to an fg head . My question is , will my stock bf intake manifold and turbo manifold bolt straight on ? Are the heights the same as bf ? Or do they need to be modified. Cheers

I’m in the process of finding a new cylinder head for my barra build. Ive got a turbo bf head which my builder said is to badly worn . my question is are all the cylinder heads from Na to turbo the same ?? I know the valves are different in the turbos . But are the castings the same ? My damaged turbo head casting numbers are - 3r23 - 6090- ac and I’ve just gotten a low k bf gas cylinder head with the same casting numbers - 3r23 - 6090- ac , the only thing that looks different with the two side by side is the turbo one has a cross / X pattern shape on the front of the alloy casting where the Na one is just smooth . Are the Na heads fine to use on a turbo application with upgrading the valves and valve springs of course .

I’m not going stupid with power but want to build it right . Don’t like short cuts . I’ve sourced 2 blocks from the wreckers from na gas motors so fingers crossed ones good. so what part actually wears jeturbo?? ? I thought some might not get made as thick / as much internal thickness

Thanks K31th , I’ve read somewhere 1 in 5 blocks would be under thickness …

can anyone enlighten me on the factory Barra blocks and why they vary in thickness? I've had my engine builder come back and say the block I supplied is to thin (2011 fg block 110,000ks) he said its pretty common. I do have another bf block in my shed but she's done well over 300,000ks ... is it worth pulling a block from a wreck with low ks or does the ks even matter is its going to get machined and honed ect?/ cheers

Pm sent jeturbo . Just getting everything sorted atm . Found a low k fg block with the 2 dipstick holes my cars a bf so I’ll be using the front . Changed the sump , girdle and oil pick up 👌 . I was told by my tuner to find a low k fg motor and not a bf ? The blocks are identical so was a little confused 🤔

whats your cost for those jeturbo???

PW for the win!

im leaning towards the nitto range with the I beam.. I got a pretty good deal on ditto just seeing if they are the old JE stock or the new CP nitto range. the bloke at nitto said they have changed to cp and not je anymore . the je nitto range was still good he said.. has anyone noticed any difference in the atomic rods with the pressure fed gudgeon gallery ?

Hey all , I'm in the process of doing my first engine build on my Barra 6 , I'm tossing up between Atomic Superleggera conrods atomic icon forged pistons or nitto / cp forged pisons and rods .. both are in my budget and I've head good things about both. the atomic gear is a bit cheaper , and differences in H an I beam for choice ? looking to reach around the 550 - 600 rwkw power.

Can you do this without removing the engine from the car ?

Would a bf f6 engine still be better than the Fg xr6t or no?

Are the bf f6 engines identical internals to the Fg xr6t engines also ? Same pistons
