Just Got My First Import Gtst 93 From Victoria

[ozdaz]

This was one tune with stock ECU

[ozdaz]

My hassle is what the two guys did in 5 months between him an me.

[zebra]

Can't tune the factory ecu.

Which means it still has the standard injectors and MAF.

So its not all there for anything more than 210-220kws

[ozdaz]

I was told yesterday it was running really rich an can't change that till it's tuned but better than lean ?

But they were talking to a Nissan moron ,now I know how other people have felt when I'm going on at a mile a minute on other topics.

[Manuel Kasko]

Larger turbo on stock ECU will run rich

To protect the engine.

No chance of getting 280kw with just a computer.

As zebra said, chances are that it's got stock injectors, fuel pump and AFM because its the stock computer.

So max with those parts and a tune is around 210-220 but with a larger turbo its going to be a laggy 210-220 I would guess.

So start planning what you want and we can help try come up with what you will need.

I'm about to run an injector cleaner through a full tank but still have to find out about the fuel system

Thx

[ozdaz]

The mechanic I seen yesterday said he'd have it running 280kw in a week, but what we spoke about the haltech platinum piggyback I'd have a safe 220-230 but your right about injectors , regulator and pump.

Are I tank fuel pumps a hassle to install?

Have a good look at you injectors and compare with photos on google images.

If your keen, take out the fuel pump and do the same.

If you spend a bit of time reading : http://www.skylinesaustralia.com/forums/topic/55845-rb25-turbo-upgrade-all-dyno-results/

You will see what is actually needed to make power, and what does nothing.

What i learned is if you have a bigger turbo and want more power, you need more fuel. The standard fuel system only has enough for a slightly bigger turbo, and small power gain.

And you need a computer to run it of course. A Nistune is suitable for anything thats not making heaps of power. ( for rb 25s i dont know exactly how much )

Almost anything else you do to the motor wont give more power, like wanky bov's etc. But things like an upgraded cooling system can keep it in good nik longer.

Dont forget the cheap effective things like exhaust and intake, though you may have most of that done already.

Personally id make it run nice with the turbo you have, and concentrate on handling.

Theres a lot of bits and pieces to make it handle good. It can eat up a lot of cash.

I couldnt use all my 180kw because my diff was stuffed, no point having power you cant use.

Ps: im jealous of your wastegate actuator, thats nice and simple, reliable and adjustable.

fuel regulator usually isnt needed as upgraded injectors dont need more pressure.

unless your going for huge power

[zebra]

How can the mechanic say 280kw without knowing what its got.

Not being a flamin mongrel.

Trying to help.

Haltech piggyback is the most ridiculous thing ive heard.

This isn't 1999 anymore.

Nistune will do everything you need for half the price and as a bonus will actually work.

Car wouldn't run with bigger injectors.

If they are purple they are stock.

[ozdaz]

I do t know enough to argue with anyone at the moment, can only quote what I'm told.

Cheers

The turbo has been high flowed an rebuilt though

[zebra]

Ok.

So what you want is.

And this depends on budget too.

Nistune or a powerfc.

550cc or larger injectors.

Larger fuel pump. Walbro or something similar

Z32 MAF

Metal intake pipe

Then better than stock clutch (im partial to os giken)

Then tune by someone who knows what they are doing...once again my preference to take it to yavus at unigroup engineering in sydney (I wont ever take my car anywhere in canberra, but im a fussy prick) others are happy with a couple of the locals.

There arent many highflows that will do 280rwkws on 98 so expect 240-250 at the most.

Now you have a quick car that needs to stop and steer better. So factor in good suspension stuff. A good diff Centre and work on the brakes. New rotors and good pads are enough for most.

[ozdaz]

It's got fully adjustable coil overs for hight and ride, so that's a good start it handles great the breaks are in good nick but stock.

exactly

[Deziner]

Dont think you can tune a stock ecu. Adjust boost and spin the CAS is about it.

[ozdaz]

Just found out the guy I brought the skyline off in apr cashed in the rego 2 days after I did the revs check an I've got to re rego it , have to either replace the steering rack or stop the leak.

3 new tyres and kill 6Db, also raise the adjustable coil overs they do hight but can I do it or do I have to get pedders or such too, same principle as a motorbike shock I think but I want the adjustment to be exact.

Also thought about adjusting the boost with the adjustable rod but don't know what distance to boost it will make.

That's where I'm at.

Also looking for a maf befote tune.

Cheers

[ozdaz]

Oh also found out they wound back the tacho it's got about 300000 not 169000 as it read , is anyone honest anymore

But compression check an engine check is healthy so don't know what to think

I will never do biz in vic again. That's 3 times now I've been screwed down there .

Be careful not only in Vic but every other state. Normalllllly - SAU people are fair honest - as we are a little tight knit community. I purchased Rosie from vic (SAU seller) and it was quite a good deal. Nothing wrong with it and all in good nick - all I could ask for was a little less lazier seller

cheers

[D.I.Y. Mik]

No pedders, they will bend you over and ......

Go to capital steering and suspension.

Or come over to my house i have the adjusting tool and a ruler.

[ozdaz]

Might just take you up in that mike, the mechanics have been giving me a sore back lately , any more bending over an I'll be paying a chiropractor as well lol
