Turbo Upgrade

[Dirty32]

Told ya...

Have a look into the Atomic engines. For $1k or even $2k more, your gonna have a much stronger engine that isnt gonna be nearing its limits like an F6 one will. Even look into individual pricing of Rods/pistons/bearings/gaskets etc (I know 03XR6T has listed the pricing before). Add machining and building and I reckon it will cost ya around $7 - $8K... I could be out but that's what I reckon it should come in at...

Lol, yeh with the other stuff, running 20psi on a built engine is no probs, nor would over 400rwkw be with a MW opt 5 or 6...

Your def gonna need to address the clutch for 450rwkw.

I agree with everyone else that your making a grave mistake if you use an f6 bottom end.

Yeah seems that way, only early days yet though I guess, and between factoring in a built engine and bigger turbo, and exhaust, oil pump and bigger clutch etc I know I'll be lookin at 10k for sure which doing over 18-24 months im fine with

[Dirty32]

Hate to put a dampener on it, but $10k is a very conservative guesstimate...

Its gonna cost ya over $2k for a good clutch, between $6 & $10k for built engine and tuning (depending on components used), at least $1500 for any form of exhaust, over $1k for billet oil pump gears and a hi flow housing and god knows for the turbo (again depends on what you use)...

As you say though, if its over 2 or so years, it aint so bad. Your gonna have a beast of a car that's gonna pull harder than a thai hooker that's been promised an Aussie Visa!

Ill be watchin the project with interest dude and good luck!

I would say more like 15 to 20k

Thanks mate ive been looking into different things for a while, realistically from what I have researched I'll never hit 450 unless I threw 30k at the car. I've compromised to the more achievable 380-390 figure. But also decided that with that figure I probably wont end up changing the turbo as one thing that was pointed out was that there is no point having a car capable of those numbers if you dont like or enjoy driving it, and putting a bigger turbo on will give me more lag which I do not want.

I've been speaking to a friend of the family about things also to get some advise. So at the moment I am looking into:

- built f6 motor and replace the rods and increase boost to 18-19

- either a second hand AP clutch with 1 ceramic disk or opt 5 clutch

(not using the car for dragging so have been told opt 6 clutch could be too aggressive)

- Latest spec Nizpro IC

- Still looking at the nizpro 4" through exhaust (but also been advised an xforce single 3.5" with 4" dump would be up to $1000 cheaper, and still make good power)

- possibly a bigger cooler

- And though it has no influence on power a bigger diff either 4.10 or 3.75 which is a std BF diff.

Outside of that im then up for bigger brakes and therefore bigger wheels as just running the stock 17's atm, but theres another 8k alone lol

Anyway it's like how do you eat an elephant? One bite at a time, so when I speak to Simon next week I'll just have to ask if this is the right direction to head in, and how can or should it be broken down and then just take it from there.

Thanks again for the replies guy's

Don't buy an F6 motor ad change the rods unless you blow your motor up. Buy a re-build kit for 3500 and you have a stronger engine for the same money.

Nice idea for a build it seems to be the idea that 400 is quite easy to reach but honestly you are in for a whole lot more then you think.

But anyway, I run a mw option 6 in my car and its going to really change the way you drive/drove it they are insanely bitey and not the nicest thing to drive in traffic. And second you will need brakes before you do those engine mods if you like living.

Dont really need to change wheels if you get a decent set of dba rotors and pads. Maybe look at things like bigger fuel pumps/injectors etc as well for that sort of power but hey gl to you. Hope the box holds.

Have gotten some more confirmed prices on the things I mentioned which will get me to the 380-390 mark and not much more at all. As per one of the other post's I wont be using the opt 6 clutch as it isnt suited for the style of driving so again will be one of the ones I mentioned previosly.

The brakes for me come down to personal preference in terms of when you do them imo. So I've planned to do the engine mods first, and I will be going for Brembo's front and rear so I do need to go for a bigger rim, but still havent settled on a look yet. Once the mods are done it won't be that long before the brakes do get done so If I can't control myself and drive responsibly with an extra 50rwk then I have no business driving these cars. Plus the brakes im running now arent exactly stock they are an upgrade and do pretty well at pulling up 341rwk.

In anycase the orginal point of the post was to get ideas and advice for a bigger turbo, so as I'm more than likely going to keep the turbo I have I'll repost details of the next mods with results in another forum.

Personally I would be more than happy with 340 rwkw's but everyones different.. You wont see much of the 390rwkw on the street, I imagine alot of wheel spin in your future..

Good luck with it all
