700hp turbo setup

[mac30]

Hi guys,

I am still deciding if i should purchase this turbo I saw. Dont know the exact specs but the seller tells me its a 700-800hp garret turbo. What I like to know is how much KW's I could expect atw? Turbo starts kicking in before & after internals? What specific parts are needed for internals if I were to utilise all the power available? And lastly a good workshop that is familiar with skylines to make the manifold and tuning?

Thanks in advance and sorry bout all the questions, just need to make sure if I should go ahead with the purchase.

dude.. all you have told us is your putting a different turbo rated at lets say 750hp on your car.. we would need to know some exact details like a/r's etc..

[Cool Hand Luke]

You could have a 700hp turbo that makes boost at 3800rpm or one that doesnt till 4500, you really need to know specs.. internals will allow you to run higher boost and revs, but wont really effect the spool up time of the turbo, but once again depends on what cams, what exhaust, what turbo specs, how much and how big your piping is, what intake you run

When anyone selling your something tell you it SHOULD like in your case recon it will make 700hp, usually turns out to be full of shit, the turbo is a truck turbo where u would need a rotor that revs to 10grand to get it to sppol up or is totally farked with farked core and wheel!

But it if is a real 700hp tubro i hope u have 10 grand min to spend of other parts to actually get it to run properly!

Either way i think u r dreaming if u r thinking on putting it on a stock car.

If you are serious about building a big hp car, I would only suggest that you go out and buy a book called Maximum Boost by Corky Bell. Perfect if you are new to the world of forced induction. You will be able to ask the right questions and have a pretty good idea of when someone is pulling your leg.

Just consider too that even circuit cars dont make this much power as it is too much for them, so it would be a waste of time on anything but probably a drag strip.

Thanks for the input.....

The turbo did come from a rotor and the owner reckons its a t5 (watever that is!). Anyways I guess u guys r right, its quite a lot of power as my initial aim was to get 300kw. I have done some calculations and 10K would be roughly wat I need to get this figure if parts r seconhand n not touching the internals.

In the mean time I'll just b patient for the right turbo to come along then.

Thanks again.

mac30, is it a stock car? good luck getting 300rwkw for 10k, I have alread spent 30 (from stock) and still counting, still havent got 300rwkw, still havent got stock internals.

[mac30]

Steve,

U think 10K is too low. Ive based most things to b 2nd hand (turbo at least!) and have already included labour. My car is quite stock, the usual mods - exhaust, filter, boost, I/C waiting to b installed. I like to keep the internals stock to achieve close to 280-300Kw. Wat have u done so far? Wat r u getting atw?

hi my dad sells those 700 hp rated turbos for like 2150

just thaught i would let ya know

om me

700HP is too much for a streetable or track-able skyline. Only good for drag racing - It's all or nuthing. And like Steve says, plan on spending 10-15K on the engine to be able to handle the power - then clutch, then driveline, gearbox, diff, driveshafts, then you got to brake - suspension, handling, tyres.

......and the list goes on !

[Steve]

Well my car was completely stock, so far

HKS 3037S56T

Manifold

Clutch

Cooler (you already have)

ECU

EBC

full exhaust

wastegate

CAI and podbox

Plenum

Wheels

Cradle bushes, and hardmount bushes

castor bushes

Coilovers

strut braces

sway bars

several tunes for different stages, ranging from 200 to 600 a go

Body kit (I justified this cos I wanted a big hole for my cooler)

Cams

Cam gear

Headgasket

A second plenum cos the first didnt deliver

injectors

fuel pump

and a few other bits that dont rate a mention. I had a mate ask me what I had spent on the car to day (before another 1.2k for a plenum, or actually getting the cams and head gasket and new plenum fitted, which looks like it is going to cost 1.5K all up with all the added gaskets, head skimmed etc) and it was just on 30K so already that is closer to 35 (still have brake upgrade to do and camber arms and tyres)

the biggest problem so far is getting the power down - I have 256 at 1 bar, but on 1.2 bar (not sure what it has) I cant get traction in any gear, so I will be buying some rear camber arms and some nitto tyres - hopefully sort it out. I have the head gasket going in this week, hopefully tune next week.

Just a decent turbo set up is going to cost you close to 5K all up, need a decent ecu tuned (2K+), and a good clutch(1.2-1.5+), fuel pump(400 and injectors(1k)

With the mods you have, you may just make it under 10k, but dont count on it - you still have to install the injectors, clutch and fuel pump - there is another 6-700. the above costs are conservative, like everything else the costs always blow out.

Good luck - but I seriously doubt you car will be very driveable with a 700+hp turbo. Much better off going for a good steetable setup.

well said steve, my new 600hp turbo will be ready hopefully to bolt up to my custom manifold my end of this week.

And there isent much change over from 10g just on performance mods.

Where does your dad work?

[R31Nismoid]

for 10 g's you wont get 300rwkw.

You have a vast number of supporting systems that need attending too at the same time.

It's not a case of bolt up away you go with THAT much power.

hi is like an agent kind of thing for garret but he dose alot of other shit too.

like importing old vintage cars from japan

which is just a hobbie
