That is true but will not sell skyline

 

will keep it and tune it later .

what is standard injectors good up to?

 

the issue is when I am calculating the cost it can easily exceed 8-9k in pounds which I could be putting toward an m5

 

i have split fire coil and think i can upgrade exu to link and turbo to straight fit ones which should give me 330 to 340 bhp at flywheel

 

i own an intercooler so can upgrade that as well for no cost

Or thinking more



I initially wanted to go all crazy with 500 bhp but soon realised it is too much work to do at this stage due to personal circumstances
I work 6 days a week and want to do it all myself


But i don't want to wait for a while to get time and also lots of expenses for this
So for short and maybe mid term i want to tune it so have much better performance than stock

Planning to buy m5 in few month

So far i have

Boost controller

K&n air filter
Splitfire coil
Okish intercooler . It is rated at 500bhp but looks like one of those chinese ones which is sold by a uk firm . It came installed
Coilover
Braided lines ..
Uprated brake (350mm) with brembo

What I want to do is

Walbro 255 - £80

Link ecu - £1400
Maybe injectors depending on current injector capacity £400
Existing turbo or direct bolt on ??
I have seen posts people saying you can change the ceramic shaft and others saying some firm make a modified t3 housing

I don't ideally want to change manifold and clutch

With above setup how much hp is realistic ?

I am thinking with around 2-3 k i should be able to get 400 bhp at flywheel
Is that too ambitious?


There are Nistune dealers in the UK.  Buy locally.

Buy the HG turbo from HG in Australia and just pay the $3.50 or whatever it adds up to for import costs.  Stop thinking about it and just do it.  Also get whatever he says you need to fit it (hoses, connectors, etc) from him.

You will need injectors.  Just buy 1000cc Bosch EV14 based ones.

You will need a Z32 AFM if you use Nistune.  That's the price you pay for not swapping to a completely different ECU.

Thanks GTSboy considering most of times you are sarcastic but thank you really:)

The import cost is 20% which is fine but what isn't is that I understood it as I need to send my turbo, they will change shaft and then send it back which means AU may charge import and uk do the same on return

If they sell one without sending mine then that will be great

Will get injectors. What brand would you get

As for AFM i am getting link which comes with a map sensor . I believe this is replacing the current afm installed right before air filter
( i read the difference between afm and map but can't recall it)

Yes but extra pressure can heat fuel up if not used
 

2 words.  Voltage control.

Also, don't buy a high flow from HG.  Buy an ATR to suit your power goal.  But even if you did get a highflow from him, you can just pay him to source a core for you.

Could you decipher this please :D

Who is HG and what do you mean by him sourcing a core for me

Apologies not sure what you mean by atr

Ok so when i install link ecu which comes with internal 4 bar sensor then that will replace the maf? Do i just unplug it

Would i need external maf if I am not going above 20-30 psi? In another word is therea difference between external and internal maf if i don't go above 20psi?

Should i get a new iat?




I am also researching voltage control so can install a bigger pump . Is there anything specific people use? I am wiring a new positive and negative direct from battery to pump to replace existing cables which cannot provide a higher voltage

ok I am about to buy the link plug and play

question I have is, my car is not running well due to boost pressure control ( Hitachi Bosch PS66-01) not working (un plugged).

 

I don't want to waste £120 buying that sensor so would you keep driving car as is with standard ecu or buy link and drive it with base map for a while ?

 

 

It will be good few month before I can take it for remap .

my real question is how reliable is link base map

There is no such thing as a base map.  ECU goes in while the car is strapped on the dyno.  Do not half arse this stuff.  Buy all the shit you need and do it all at once.  This half half stuff will cause you nothing but pain.

Why is the boost sensor disconnected?

the nipple which you connect the hose to is broken and brand new is between £120-150

an ecu is £1300 . the sensor won't be used when putting link it so wasting money really but don't want my car to run bad as a result

 

might just bite the bullet and get the sensor

Which nipple? If you mean the boost source I drilled and tapped a hole in the compressor housing - pretty sure the nipple was less than $10

Sitting down and thinking through this i am still going to get injectors, ecu and pump( bought walbro255)

Then really i am not saving anytime as rather than using hyper gear i could get twin scroll with internal wastegate
The only extra i need is exhuast manifold

The only hassle is custom downpipe. I am not paying fortune to tuners and do it myself so how do you go about getting the right downpipe sorted?

I guess the manifold will be a split design but you still get one twin port to mount turbo on
From turbo to exhaust would you have two pipes or one?


If I go top mount, does it fit in engine bay with my carbon bonnet?

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
