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

Lindsay

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...

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).

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...?

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 :)

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

pete :cheers:

      Wheel Sizes & Offsets For Skylines

      By Kinkstaah · Posted

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
