New Turbos..

[r32gtrv-spec]

g'day,

i was thinking about buying a set of thease for my r32 gtr.

http://cgi.ebay.com/ebaymotors/Garrett-GT2...sQ5fAccessories

my current turbos are gt2530 from what i was told by the car dealer i purchased the car off (very dodgy bloke/..)

i want to get the block bored to around 2.8L or even 3L, does anyone know if it could go that far ?

the only reason i want to bore the block is because the turbos will lag like mad rite ?

thease are the biggest twin turbo setup i can find..

i basically want to achieve around 600kw for my track car..

if anyone has had any experiance with thease turbos, or anyone that has a better opinion on what should do would be much appreciated.

I have not had any experience ( im poor i only own a gtst) but from what i have seen to get 2.8l you use a stroker kit and for 3.0l you use an rb30 bottom end, im guessing very little inside your motor will be left standard to achieve a reliable 600awkw so 3g+ on turbo's will be the least of your expense.

[GUN_METAL_GTR32]

rb 26/30 (obviously seriously built)

gtrs turbos or something similar/bigger

a f**kload of boost

should definately see u over the 500kw + mark buddy

i wouldnt want to know what the bill would be like though lol

[R31Nismoid]

600rwkw or 600kw @ the fly?

Either way, it sounds like you need to do more reading mate.

If you think you can bore a GTR block out to 2800cc total you're already showing a little lack of knowledge... let alone needing 600kw in a track car.

Also turbos having mad lag, another giveaway perhaps more homework needed.

What is the budget?

What are the current mods?

What are your current lap times?

What lap times are you after?

Hmm that horsepower level will cost around the $50K minimum. I would suggest a more realistic power level is what is required.

[joeyjoejoejuniorshabadoo]

hope you have DEEP pockets lol....

do you realise what 600rwkw will be like? i have 300 and the thought of doubling it is just f**king insane

[Parag0n]

Those turbos are tiny for the power you want, A/R .64? Please.

For 600kw at the wheels you're looking at some serious horsepower, and a built engine, you'll have to fortify the top end with various JUN / Tomei / Whatever parts and maybe even the bottom end depending on what you're going to be using all that power for. Remember you have an RB26 not a 2JZ lol.

Secondly I wouldn't buy my turbos off ebay, I'd buy from a registered Garret dealer where you have things like warranty.

If I wanted 600awkw from an RB26 I'd get 2 GT35R's with .82 rear housings from a registered Garret dealer, like Horsepower In A Box.

Then I'd find a workshop willing to tune such an animal and an ECU that would be reliable at that level of power, you're going to need a custom fuel setup, at least a 2.5L surge using something like a Carter Gold lifter pump and 2 x Bosch 044's with return lines.

I wouldn't bother trying to bore out your engine to a massive 2.8L, is that even possible? Instead you could purchase a stroker kit.

This is all going to cost big dollars, I wouldn't undergo this project unless you had at least $25k and a workshop that you could trust.

Pretty sure he means 500-600kw @ flywheel.

[R31Nismoid]

well 600kw @ the fly is still what, 500rwkw give/take?

[Strik3r]

I'd get 2 GT35R's with .82 rear housings from a registered Garret dealer, like Horsepower In A Box.

that is stupid. 35Rs will flow over 400kw atw EACH. the lag on that sort of setup would be stupendous.

HKS GT-RS's will make the power you are talking about. Lag will be an issue and will require a lot of money & time to try and negate. If you don't know what your doing and havent done much track work before (assuming this based on your post) then start off small and work your way up. You will lap faster in a responsive 400hp gtr than in your 700-800hp setup with lag and traction issues.

amen

[bradsm87]

I'd def prefer HKS GT2835's. They're a bit bigger than the GT2871R's in the turbine wheel which is exactly what the GT2871R needs.

[PM-R33]

Well considering he said 500-600kw i would be thinking 400-500rwkw which is "achievable" more so than 600rwkw.

If you wanted something "fairly responsive" (hell i dont call anything with that kind of power on a RB responsive but whatever) with that kind of power i'd be looking at something along the lines of a 30/26 with twin GT-RS's.

But as has been said, why so much power? I'd be looking at lower power levels but be concentrating on response.

hioctane have demonstrated that a 26/30 with 2860-5's makes for a very quick combo.

with a hollinger...

and special diffs...

and an endless budget...

realisticly you should budget atleast 70k to do it properly with a box and diffs etc and thats not including labour from a workshop

[TiTAN]

even without the extras a 350-380kw 26/30 is more than enough power to throw you around a track quick

It is not stupid it's a solution that I know of several drag cars running 800-900rwhp at only 20psi.

Remember the OP never stated what he wanted so much power for.

Does he want a responsive track car? a dyno queen? highway warrior? something that runs 10's?

More information needs to be posted.

All we receieved was an ebay link and an "I want this much power"

How long is a piece of string? etc...

Umm ye he did...

+1 those hioctane gtr's are insane

I think 600Kw at the crank let alone the wheels is an unrealistic goal to have in the first place .

If you want to have a usable rev range with that sort of output I think even 3 litres (200 odd Cu ?) is a bit lacking .

Having telephone number outputs is one thing and being able to do something useful with it , let alone affording it , is another .

I don't think 600 hp at the crankshaft is unrealistic in a track RB30 but I don't think it'd be a nice drive on the street .

A while back it was mentioned to me by possibly SK that RB30's can be stroked usefully to about 3.2-3.3L and compared to some of the zillion dollar mods people do at times it may not be as expensive ($/Kw) as many think .

Std bore/stroke RB26's revved to 11 may be one thing but the budget must be horrendous .

IMO need more cubes , do any of the later 3.5L V6's have any hope of going into an R32/3/4 ?
