Is It A Must To Get New Fuel Pump And Injectors?

[PhilGTR]

Hi All!

Well after a very long time without my R32GTR due to a rebuild as I blew my rear turbo causing the pistons to get scroed badly , it is now finally back on the road.

So far I have got new forgies and rings, n1 oil pump, n1 water pump, main and big end bearings, polished head and crank, stock rods, new timing belt, new r34n1 turbos, apexi pods, trust bov, exhaust from front pipe back etc etc.

I am running it in at the moment but its still got the stock ECU in it at the moment. I am definetly getting a PFC and boost controller which will be my next mods, but is it necessary that I buy a new fuel pump(bosch 044) and injectors(Sard 700cc) before i get the power fc/boost controller installed and tuned? Or could I get away with the stock injectors and pump? Also what boost controller do you guys recommend?

Appreciate any opinions and advice!

Cheers

Phil

I would be doing them all at once, saves money on re-tuning etc.

You dont need 700cc items, you can stick to Nismo 550/555 or whatever the size is for the GTR.

id deffinately do the fuel pump. It depends how much power your after as to whether you need new injectors. If you want more power then they can flow then ofcourse youll need to upgrade. What is your goal?

Thanks for the reply guys.

Well im looking at around 300rwkw. How many cc's are the standard GTR injectors?? So for max of 300rwkw what size injectors would i need so its not being pushed to its max?

Stock injectors ones will go to around 300rwkw... depends on the car it seems as some can and some cant.

You have pistons, stock rods are fine etc etc. So there is no worry about something breaking, i'd get injectors and work the N1's to thier potential

440cc

my injectors maxed at 370rwHP

Thanks the help guys, I guess I will get both the pump and injectors to play it safe.

yes i wouldnt be running stock injectors at 300rwkw day in day out. you are just setting yourself up for some heartache down the track. i say just grab a nismo pump, and a set of sard 700cc injectors, then alll your fueling worries are solved.

What about the bosch 044's? Are they any good? Im thinking of getting that pump.

Stock pump is fine however a 15yo pump may not be, so a nismo unit is ideal for your aplication. Stock injectors wont do the job you will need 550's, of course it will depend on how hard you want to push the turbos .

700's are overkill for the turbos you have but its your call as sards are very cheap .

I've got exactly the same set up and have gone the sard 700cc and bosch 044 route. No problems, plenty of headroom if you want to go cams down the line and as mentioned both parts are in the cheaper spectrum of things that will do the job.

I've got a Blitz dual sbc spec R and am experiencing some difficulties with getting stable boost. I know of other GTRs that use them and have no dramas so i'm guessing i need to do some thinking. Some guys swear by the ProfecBII and i've been told that this is for a good reason in terms of bang for your buck.
