GTR 'Powerup' Q's

[PSI_GTSII]

Ok my GTR will be here next month, and I will want to increase the performance somewhat.

Basically i'm looking for 120+mph Terminals whilst retaining good driveability.

My plans at this stage are purely bolt on:

Deal with any other issues if & when they arrise;)

1. HKS2530 or similar low mount turbos, although the GT25/30 seems a lot cheaper...?

http://www.horsepowerinabox.com/HPIAB2/prod15.htm

Or can the standard turbos be rebuilt using larger 'steel' wheels with a HiFlow as I've had good results in the past with this?

2. SARD 700cc Injectors

Will these run with Standard ECU?

3. Power FC

Car already has full 3" exhaust and Pod filters, and GTR cooler should suffice.

Will this get me 450+rwHP and 120+mph terminals..?

Any other suggestions? or good places to buy parts?

Cheers

[Mr R32 M-Spec]

greenline is always good man

I have the following and my car makes 218.2KW

MINES ECU

front pipe

3" cat and 3" exhaust

panel filter

Blitz EBC

450hp you will be pushing it with that set up, i own a R32 GTR its got HKS2530's,HKS Cams, Sard 700cc injectors, upgraded fuel punp, Trust drag intercooler, Twin 3inch system from turbo's, Link engine management and AVC-R on 20psi i pump out 330kw's

I want top mount twin turbo's for it then the power figure will really rise, the 2530's are limiting the power output but they boost up quickly and smoothly so its a fairly streetable car at the moment

I have seen a write up on the GT2530 turbo's and they say they are pretty much the same as the HKS turbo's apart from the price...

2. SARD 700cc Injectors

Will these run with Standard ECU?

No these will not run with standard ECU. Power FC is really the best option to take regarding the tuning a of a GT-R.

450hp at the wheels is possible with the the GT2530/ HKS 2530's but you will need to run some pretty big boost to get it. An easier to get this power output is to get some nice cams for the RB26 i.e. 276deg.

This will make your car have excellent top end without the need of running big boost i.e. 20psi (over).

HKS step one cams 272 272 with some 2540's would easily make the 450rwhp but i would start looking at building the motor with that type of HP.

[Dash]

Look up the specs on Pnblights car

Pretty much exactly what your trying to achieve uses garett turbos too.

[PSI_GTSII]

Thx Guys.

It mentions what 'looks like' HKS 272 on the auction sheet!..?

Hopefully it does have the cams fitted

The GT25/30's seem a fair price from HPinabox, these are looking like a good option atm.

I do not want to turn it into a 'narrow high powerbanded' drag car, more of a flexible 'MC motorsport' club racer style thing.

So no one would reccomend the rebuilding of the standard turbos or knows anyone that has done this...?

[R32-GTS]

not worth the hassle and price

[PSI_GTSII]

One more quick Q!

What is the Biggest Injectors anyone has run using the standard ECU?

Or is anything other than the standard injectors out of the question.

Cheers

[R32-GTS]

550's with safc

carefull with these turbos as they are not true bolt ons the compressor out and turbine out put are different to the gtr turbos and will require custom piping and bump pipes

550's with safc

Thx Simon.

Not really worth it then, as 550cc injectors are no cheaper than 700cc units and the SAFC is only about $500 cheaper than the Power FC......may as well spend the extra

carefull with these turbos

You mean the GT25/30's..?

I am actually leaning towards GT-SS atm....closely followed by 2530s...Hmmm...decisions decisions

[R32-GTS]

I would go the gt-ss as well as ppl have had good success with them. The sard 700cc seemed to be the cheapest injector out there and the power fc is also damn cheap now.

your right on the money

here a combo i will make 450rwhp(walk in the park) if tuned well

APEXI pfc (avcr is a good boost controller aswell)

320hp garret turbos or HKS 2530 (stay away from the horse power in a box set)

700cc sard injectors

Tomei poncams 260deg 9.15mm lift (or close to)

Tomei adjustable cam wheels (take the time to adjust them)

afms 20/25rb or z32

turbo back exhaust (twin 3" dumps into 3.5" single good place to start)

custom piping to the new from turbos to 80mm afms(3')

this combo is good for a great deal more than what you want but it will give great drivability and future development.

my car running 530rwhp

rich madsons r33 on good fuel have seen run 550rwhp+

and these cars on std internals have been going hard for sometime now with out a single problem.

hope it helps
