Turbo Upgrade

[Russ F6]

Yeh do it right the first time and save yourself in the long run. Get a built engine, much stronger than a F6 bottom end.

hmmm I wouldnt have classed spending 5k on a bottom end NOT doing it properly. As far as extra boost go's I'm able to go to 20psi right away but until I re do the bottom end I want to leave it, and the clutch I have is rated at 1000hp, which is over 740kw (unless the info I was told about it was BS but I trust his knowledge)

It's going to come down to $$ and also when I will be able to do it I think. Doing a rebuild gets me inline with nizpro stage 3 which is 12k. Re doing the bottom end with upgrated plumbing and exhaust gets me to about 7k and according to nizpro will give me decent power and quality running return. I will be having a good discussion with them when the car go's in next week for service and tune.

Up until now everyone that I had spoken to had said (based on own experience and observations from others) that upgrade of bottom end plus the new exhaust will see me hit just over 400 rear and then speaking to alex from plazmaman suggests one of their 1000hp coolers will see me gain another 30-40kw.

In anycase it's showing me there are alot of options and equally numbered opinions which for someone like me who has very little knowledge and understanding in this area can be both good and bad. At the end of the day having as much knowledge going into these decisions as possible is highly preferrable as it exposes me to things I would not previously have thought about.

Cheers all for the help and feedback, very much appreciated

good luck mate, and if you only end up putting the f6 bottom end in at least do the full oil pump body and billet gears.

Who told you that you could run 20psi through a BA engine?

I think you would be on pretty limited time with that but anyways...

Again - Im not sure who told you that an Option 3 clutch is rated to 700 odd kw's. Mal himself only rates them at 370, granted he has heard that there are some vehicles pushing more than that, but if the manufacturer rates them at 370rwkw then who told you they would handle 1000hp?

I agree that if you spend $5K on an F6 bottom end then you are doing it properly. For an extra $2 - $3K you could have a bulletproof built bottom end that will be able to take more than an F6 bottom end will. There are cheaper options than to have a Nizpro built engine. Obviously pricing will have a lot to do with who does the work.

There have been cases where F6 bottom ends have let go at around/over 400 (arguably tune related, arguably due to the build standards and tolerances from Ford), again granted that some people are taking it above that but most people seriously taking it over the 400 mark have considered building or built an engine.

Im just giving you my opinion on what I think would be most suited for your goal. Yes $$ also has a lot to do with it, but you didnt exactly declare a budget for us to work to... As you say, the more opinions you have, the better suited you are to make a decision.

The guy I brought it off advised me that if I was to do the bottom end I could push it to 20psi like I said until I did that I'll be keeping the boost where it is. Back to one of my original posts my ultimate goal is to have a final product that is built tough and is going to last. Any extra power I pick up is a bonus, upgrading the bottom end or doing a rebuild added with the other mods I want to do will give me that built to last end product. I'd love to say money wasnt really an issue cos if it wasnt id be doing a full rebuild and looking at a stage 3 or 4. But ideally id like to achieve it with 7-8k over say 18 months but being realistic it could be 24 months and 10k.

Like you said mate lots of opinions out there and speaking to the guys that deal with it everyday like the nizpro's, cv performance', etc is the only way im going to learn whats best. Another guy I have been speaking to has given me the list of what he runs, which is:

-t04z turbo,

-manifold,

-external wastegate,

-dump pipe,

-ces exhaust,

-nitto plenum,

-injectors,

-valve springs,

-t56, single plate clutch,

-044 fuel pump and surge tank,

-pwr cooler,

-custom intercooler plumbing

and with a good tuner makes 410rwkws. After a rebuild and a few changes it made 460rwkws. He's actually wanting to sell t04z turbo as he has just bought a t51r.

Like I said the more info I have the more prepared I will be when I go and speak to the guys. I'll be able to ask the right questions and give some of the examples from here that I otherwise wouldnt have thought of.

I double checked with the guy I brought it off and turns out I am retarded and got it backwards the gear box is rated for power outputs of 450rwk+ and that yes I would need option 5 or 6 clutch. And as far as running 20psi, he actually meant it could go to 20 all day everyday once the bottom end was done. And I'm pretty sure I'm dyslexic

G'day,

I just rejoined today after a long absence from the site. I have a BA XR6T and it sounds like the bearing has gone in the turbo; what's the best way to get it fixed?

Wrong section silhouette, but take the turbo off & send it to one of the site sponsors

Sleeper6t, if you're chasing 400+ then go for a built bottom end. Plenty of people are running 380 - 420rwkw on BF bottom ends but they are guys with BF's. There's no point spending $5k to put a BF bottom end in & run it on/over the edge when you can have an atomic short fitted for ~$1k more
