I have a mildly modified R33 - exhaust, FMIC, etc. The usual basic modifications.

The car came with a Trust bleed valve, which I have removed. On stock boost, the car is pulling 165-170 rwkw.

I'm pretty eager to reach 250 rwkw.

So far on my shopping list (performance wise) I have (in order):

- Apexi AVCR.

- Power FC.

Hoping to reliably have around 200-220 rwkw at this stage at around 11-12 psi.

- Injectors and a new turbo of some description.

So, my question is what sort of injectors and what sort of turbo would best suit what I'm after? And how much is all of this going to set me back (inc. labour to install it as I'm a n00b)?

My other question regards defects. With summer coming, I know I'm going to be defected. I always do my best to minimise defect pain, ie. connecting my turbo timer to plugs so it can connect/disconnect in ten seconds etc.

So, are larger turbos / injectors legal? Because I don't know how keen I'm going to be installing them and removing them each time I get a defect.

I know a Power FC is fairly easy to remove generally, but what happens once I upgrade my injectors and turbo? Does removing it turn into a long or expensive process?

And lastly, my current bleed valve takes around 10 minutes to connect / disconnect. I don't really know how EBCs work. How much harder will one be to remove for a defect and connect again?

I suppose this stuff can't be that hard if so many of you do it so often, but I'm pretty slack and tight on the pennies so I want to know what I'm up for.

P1E i am doing the exact same thing that you are on about with same power figure. I have so far:

- full exhaust with split dump pipe

- bosch 044 fuel pump

- power fc

- cooler

- oil catch can

just waiting on 550cc nismo injectors, and turbo is taking a bit of time (HKS GT2535). its low mount so defects i would not worry about. To do it properly with no short cuts etc and quality parts it will cost around $5,000 or maybe a bit more depends who u go to.

What other mods have you got? 170rwkw seems high for just 'exhaust, FMIC, etc'.

Getting too 200 at 13psi shouldn't be too hard, but at stock boost it might be harder. Bank on needing a fuel pump. You should be able to push the stock injectors to around 220rwkw (might need a fuel reg too).

I'd save the cash and get the boost control kit for the PFC, unless your really keen on the AVCR.

It's a big jump $$$ wise to take it too 250rwkw.

Do a search as there's heaps of threads on turbos for this power range, seems the 2835 is a good match.

Yes, I have a GTR fuel pump already and an oil catch can, but that's sitting on my floor at the moment.

I'm keen on the AVCR based on looks alone and based on the fact that it's about the same price as the PFC boost controller kit. Or is it more expensive?

If I'm looking at $5,000.00 for a new turbo and injectors then I might just take 220 rwkw and be happy. I was hoping $1,000.00 for injectors and ~$1,000.00 for a new turbo. Oh well, there goes that dream for the medium run.

I suppose 220 rwkw will be pretty fun after driving around on 165-170 rwkw for a year.

If I run a Power FC with my stock injectors/turbo, is it simply a matter of disconnecting it and putting the stock ECU back to clear a defect? Or is there more to it? And how much more difficult is it to connect/disconnect an AVCR or boost controller kit compared with a bleed valve?

Jay95R33: That dyno figure was without a tune also. I've had my car for nine months and haven't had it tuned at all, so it might even have some more grunt in it at 5-7psi.

The actual valve is the same between the AVCR and the PFC boost control kit, the only difference is that you get the fancy display with the AVCR (plus the AVCR can do rpm and gear select boost levels). But.... You can get the PFC boost control kit for about $350ish, while the AVCR is around double that (talking new prices here).

Yepp, if you stay with stock injectors and a not so wild turbo, you'll be able to simply unplug the PFC and plug the stock ECU back in. But if you go with bigger injectors you probably won't be able to run your stock ECU with them - it'll run way too rich.

Just on the power increase, stock car is around 130rwkwish... Your upto about 170rwkw now - so about 40kw up on stock. After the mods you'll be up another 40kw, so you should be able to get a idea on the performance increase.
