what power should my gtir be making? should i remap?

You can't fit the z32 maf as it won't run until the ecu has been mapped for it.Don't fit the injectors until you get there as you will be injecting 25% more fuel than there is supposed to be.

I'm not sure if the z32 will fit with standard air box, although I'm sure someone can help you out on this. As far as cost goes, you're probably looking at about £800, I'd guess as the Nistune mapping is £410 and then the rest of the parts and fitting etc.
Remember you'll also need to declare this on the insurance as the power will increase, it might be that the price won't change though as they often just like being told what's going on.

The standard intake pipe has some flex in it so it might do, not much difference between the dimensions of the 2 MAFS but think that as standard it bolts to the box so might cause an issue with air being sucked in bypassing the filter if there isn't a good seal.
I personally think you're getting a bit ahead of yourself. - You either want to modify and get more power, or you want to get the most out of what you've got.
This thread has gone a long way from "what kind of power should I be making" to " with a full remap, new injectors, new MAF, etc, what power could I be making". - With all the money that someone had already spent with Forge, I doubt it's looking very standard any more anyway.
Whilst people are making random suggestions, I'm going to throw-in buying some 800cc injectors ditching the ECU and MAF in favour of a Motec system with a MAP sensor instead. F*ck it; why not go for as much power as standard internals can take?
I'm going to second Jim's advice; bring it along to the rolling road day. See what it makes as it is, and fix any problems that are highlighted (if any)... then see if you want to start chasing more power.

You better add a bigger turbo to that list too then as a standard turbo won't put too much stress on standard internals ;-)

NO!. They are a different size.
They will fit with extensive modification to the connection point at the airbox and with an 80mm adapter to the intake pipe.
With all the mods you have and are intending your air box reasons are pretty superfluous.
I'd just leave everything as it is and up the boost to 1.2 bar with an safc or a remap. I ran my car for years at 1.2 bar with just an air filter, exhaust and fuel pump!
What happened to it?
Ok I see your point about getting the most out of what I have. In response, the previous owner laid the groundwork and the car needs a remap IMO in order to get the most from it. However fusion is a few hours away and the cost of nistune and remap is around £500 so I'd like to make sure I don't have to go back for another anytime soon. Hence fitting injectors and maf before remaping. What is the benefit of the motec system over the z32? I don't want more than 330bhp as I'm on standard internals and I'd prefer not to break things if it can be avoided. Won't a larger turbo increase lag further?
Also, what are the downsides of going the z32 and 550cc injector route, why is motec better? I really have no intention of going above 350bhp max. With that power, there can't be much out there that can keep up anyway.

I think Pobody's post was a touch tongue in cheek :lol:.
Motec is a stand alone management system and costs about 1.5K plus fitting/mapping, I'm not sure it's totally necessary for a 330bhp R!
As for a bigger turbo = more lag, the best thing for you to do is check out some of the FAQ's on the forum and do a bit of research online. You don't need a bigger turbo btw.
As per the advice above, get your car on a rolling road, either at the RR day or another one local to you. Doing so will highlight any problems that there might be and you can address them as and when they come up. I'd advise against changing your car if it actually works :-D

STOP!!
before you go any further, 330bhp is achievable on std internals, std injectors, std maf. you could go down the route of a remap with someone who is highly recommended (ed) or you could wait for a mines ecu to come up for sale or something similiar.
330 is easy, very easy with what you've got. 1.3 bar boost is all you need with supporting mods - clutch and fuel pump. you wont want to run high boost all the time, so get a decent boost controller with at least a high and low boost setting.

Bollocks, you can achive it but the injectors and maf are on its limit which is not good if you want the car to last.............
Better to be set up with the right kit than fit the mines ecu that is ment to run on 100ron fuel and risk fucking the car up.

Ed at Fusion can fit the Z32, it doesn't take long(make sure you have a plug too) as its just a bit of soldering and then he tells the ecu to recognise it with his laptop before mapping.The injectors you can take with you and either fit them yourself while waiting for Ed to turn up, takes 10-30 mins or let Ed fit them if you aren't confident doing it.I meant don't fit them for the drive down or you will be overfuelling all the way.

its not bollocks, this was the old school way! pity Rishi wasnt here, he had his running at 1.5 bar without problems. 1.3 bar is the very max i would go for sure without major £££££££

I was running 1.5 with no problems, but that doesnt mean it was the correct and safe thing to do. The fact that you can map a car get 38 odd mpg when cruising and have a safe car and run lower boost is better than cheapness ffs, the trouble with alot of the jap stuff over the years has been that no one actually new how to set the cars up in the uk hhence why so many blew there cars up, if you want to see what a standard engine can do the one i'm building in the workshop at the moment is heading to scotland to go in a fwd car and will be pushing over 400bhp at 1.2-1.3bar. Boost pressure just means there is something holding back the airflow into the engine.. And as for rishi and the others that gave up ask them why...........because they paid tuners to experiment with there money! Which ment that the cars were never finished.
Old school may have worked but is it reliable.........not always,And would you rather spend a few quid more on setup or a whole lot of money buying a new engine?

everything you said is 100% accurate, i just saying if he is happy with 330 bhp then thats as far as you can go with std injectors and maf anyways, a motec is just a bit extreme, but on the other hand when people get used to 300 - 330 bhp they always want more

can you really get 38mpg?

I can.Asked Ed for an economical part of the map at around 65mph, it runs lean between 16-18 afr but as there is no boost and very little load it doesn't matter.As soon as I put my foot down the map richens up again.Could probably get it even leaner as I have water injection.
