Whats been done?

[Suspense]

Hey i just recently purchased a r33 S1, and am goign through the process of workign out whats been done...

As far as i know it has the following

GCG Hi-flow turbo (happily discovered last night)

Aftermarket dump pipe welded onto a hi-flow cat, and i think 3" exhast thereafter.

HKS Pod Filter

Blitz FMIC

GFB BOV

Turbosmart Dual Stage Boost Controller

Apexi Turbo Timer

Stock ECU

Now I am thinking about upgrading the fuel pump, so i opened up the cover in the boot, and just see a few fuel hoses and sum gland thing.... which everythign goes down into... Do i have to take this gland thing off the find out what fuel pump i have. If someone can enlighten me on this process it would be great, and also how to tell if its a stock fuel pump in there now.

I was also thinking if the car may have injectors? or would this require the mapping of an aftermarket ecu? hence ruling out injectors?

That said I will soon be installing a PFC, and not sure wether i should get the PFC Boost Control add-on... or another after market electronic boost controller, such as an AVC-R? I would prefer to stick with a PFC addon, as dont really want extra gadgets unneccesarily, however am unsure of the accuracey, reliability and the ability for a PFC B-controller to hold boost, and wether boost can be tuned through the rev range with this unit?

Also i want to install an oil catch can some time this week, however all the cans i have seen only have 1 inlet 1 outlet.... i want a 100% plumback can, that i can have easy access to baffle, and require 2 inlets and 2 outlets.. should i just use "T joiners" or will this restrict flow. Am i better of just making my own?

Sorry bout the overly long post... just wishign to clear up a few things i am unsure of... thanx in advance, and please keep the suggestions reasonable... and dont go suggesting i get this and this and that to get 500rwkw.. more than happy to get 250rwkw at the end of the day

thanx

basically u would need some form of management to change injectors so that probably rules that out and the pump also (usually)

the powerfc boost kit offers basic boost control , it does not offer gear / rpm / duty based boost control , auto turbo learning boost control (where you do some 7000rpm runs and it automatically learns your boost curve) , scramble mode or any of the ricey stuff . although this stuff may or may not be usefull to you for the price difference (bugger all) you might as well get the avcr , atleast it can be removed and sold if you have to its not tied to the powerfc and you might want those extra features one day . There is a thread covering this if you want to search

with a powerfc , injectors and pump you should see 250rwkw . the turbo will be the restriction so perhaps plan a slightly bigger fuel system that could support 300+ incase you decide to get a bigger turbo later

thanks for your suggestion, i called GCG turbos, and they said the turbo is good for 260kw and 24psi boost...

but as you said i will require injectors and pump, as i want it to be a reliable 250rwkw...

Should i be leaning towards upgrading fuel lines aswell, and will a fuel regulator be in order?

Your stock injectors will look a purpleish color.

To take the black ring off to gain access to the tank then ur pump u will need a bar and a hammer.Sit the bar a groove then keep beating it counter clockwise untill u get it open.It may take a while but it is by far the only way to undo it.And make sure u put it back on the same way it came off.(I used a car jack bar and hammer)

Get into this thread catchcan plumbing question it tells all u need to know,with pics too,about catch can plumbing and will also help u decide what style setup u need.

i have a thread in the tutorial section on how to change the fuel pump to a Bosch 984. the details on what you will find are there, i think predators post on the 910 pump install has some pics for the factory pump.
