Want 400kw Atw !

[GTR747]

Hey all,

I have a 1989 R32 GTR, stock except for...

900hp Walbro intank fuel pump

2x Greddy filters

Cat back HKS Super Dragger 4" exhaust

Grounding Kit

Tien Coilovers

Front and Rear Strut Bars

They are all installed on the car, i have sitting in my room...

Profec B 2 Boost controller and a Power FC computer and a extreme double plate clutch & flywheel. The engine is only 88,000kms old in going great.

I will be getting sometime soon Splitfire D1 Coils and leads and new plugs.

I am also in the market for sme new turbos....dont know which to get though.

As you know now i want around 400kw atw, but dont want a big single turbo system at the moment.

I have a choice of...

2x HKS GTSS Turbos or 2x Nismo R1 Turbos - the reason its between these turbos is because they are available as a bolt on kit for a GTR, so there is no screwing around getting custom shit made up and so that i can do the work, as i am a mechanic in the RAAF. Get the Power FC installed and tuned by boostworx in adelaide though

Which one's do you all reckon i should go with . Has anyone used Nismo R1 turbos before as im findin it hard to find info on them, but i can get a good price for them. On the other hand im not t sure GT SS will make 400kw atw.

Any help would be great, thank you.

Doug

i dont think either will make anywhere near 400kw

more like 300kw. check the rb26 turbo upgrade thread for power and turbo combinations

400kw sounds like twin 2530s

[GTR747]

are 2530's available in a bolt on kit for a GTR?

Im not tryine to rain on your parade here

but

400 At the wheels on stock internals = Bang

GTSS' are good for around 330-340rwkw

R1s a little bit more from memory

And you will need Lots and lots of dollars to get anywhere near that power figure...

Injectors, Cams, AFMs Dump/Front pipes, Crank collar, Forged Internals etc etc

Maybe you have the budget, But as they say "If you have to ask you cant afford"

Not sure If any of the big power guys will tell you how much they have spent. But its not cheap.

Your Best off going to an engine builder/work shop in your area and straight up say. I have this much to spend, how fast can I go.

Cheers.

oh i know im gonna have to build my engine i am more than aware of this. Im not looking at installing any kit i get until i have built the enigine to handle what i have in mind.

Thanks

First question: Why 400kw? Is this a magical number or do you have a specific reason for chasing this kind of horsepower?

You will need something along the lines of HKS GT2530's or GT-RS's and a decent amount of boost, not to mention a stack more mods, decent cams and possibly some head work to achieve 400kw at the wheels.

what he said...2530's need 2bar of boost to do 400AWKW so its really stretching them too. GT-RS turbo's are the king of bolt on turbo's...currently powering the fastest bolt on turbo GTR on the planet.

save yourself some headaches, heartache's and lots of time and stress. Sell all the gear you have and buy our car...simple 500kw all day every day at a lowly 25psi.

Who has read that article in the current Autosalon Mag by Iain Kelly about how all Aussie import drivers care about is dyno figures and peak power outputs.

Not how the car accelerates out of a corner or the amount of mid-range grunt.

Id rather have a super responsive 250rwkw over a mega peaky 400 any day.

What do you want to use the car for GTR747.

Judging by your forum name its Drag Racing.

Add to that the 6-8k bottom end

Easily 20k to get you going.

I think you need to do a LOT more research GTR747, to not know HKS2530 are a bolt on option, and are the best option for 400awkw... shows there is a very big information gap.

Have a read of the Dyno sticky thread and a few of the links in the FI Guide.

They contain info on setups and what you will need (parts wise) to achieve that power.

Whoever is doing the numbers for the bottom end will also play a key part in its survival at over 650hp.

[GTR747]

Mainly want the car responsive but can hold power throughout the rev range. Gonna use the car on the street but want to be able to hold my own around a track at a track day or soforth.

I think im giving the impression i dont know what im talking about here, thats not true. But to tell you the truth, i was unsure what sort of power these 2 kits were capable off, now im getting an idea.

400kw was really just a throw around number, just wanted to see what you guys thought abuot my - A nice, quick responsive GTR - i thought that was obvious when i specified my turbo kit choices. As zebra said, i would rather a super responsive 250rwkw gtr than a peaky 400rwkw gtr.

GTSS then

then spent the money (and lots of it) you just saved and spend it on tyres. more suspension work and track time (oh and fuel)

[R31Nismoid]

2530's are by no mean a 'peaky' turbo, but the sheer cost of 400awkw vs a more easily achiveable 300-330awkw is phenominal as it can be done on a stock motor for a start.

GT-SS (or equiv) gets my vote if you revise the 400awkw to around 300-330rwkw, response as stock, pulls to redline.

Loads of info about on them, here is a start.

Also plenty of HKS 2530 information around and who has achieved what etc.

(and their equivs you'll find if you read the 2530 threads)

[GTR747]

R31Nismoid - Thanks alot for your help brother - Im reading as we speak.

Of course 400kw is gonna cost to maintain, no questions about that.

So your voting for the GTSS kit then, alrighty then, so far that kit is looking like the one to go for.

Ill be more than happy with a responsive 300rwkw!!!!

[Simon-S14]

so you went from 400 rwkw to 300 rwkw just by taking advice from those in the know.... wow some people do acctually listen!

as for holding you own around the track, 400 rwkw doesnt mean you'll acctually do this... you'd more likely be whipped by a car with 250-300 rwkw and a responsive set up and able to put the power down better.

more power doesnt always = faster....

more power doesnt always = faster....
