N1 Turbo S Wastegate

[RUSSMUSS]

hey guys & girls,

i have a r32 gtr with n1 turbos that will only run factory boost. i have already checked the factory restrictor and it has been removed so my question is what are the factory wastegate pressure on these turbo??? why would it only be .68 bar??

i want to make 330-350rwhp just wondering what injectors i will need??? any what other mods do you think i will need?? i currently have a apexi pfc, sard reg, 044 pump, k&n panel filter none of which is fitted as of yet but will be in the next w/e or so.

thanks russell

I know my R32 GTR stock turbo's wastegate actuators are set for 10psi, 0.68bar = 9.9psi. With the restrictor removed, you should be seeing 1 bar with the factory boost controller, if you want more you are going to need to get a manual boost controller or a electronic boost controller.

To get 330-350hp is fairly easy, just get that PFC tuned and you'll make 350hp with 18psi or less with those N1 turbos (might even get away with using the stock ECU at those kinda power levels, personally I would sell the PFC and go Nistune). Stock Injectors are good for 375hp+. I would recommend a hi flow cat.

Dump the FPR, only put it on when your injectors are maxed out.

thanks moddles2 for your help. just a couple of quick questions what is nistune?? a chip or computer? why would you recommend it over a pfc??. what sort of power have you made with your stock turbos??

thanks russell

If you have a PFC - keep the PFC. No reason to change it.

As for more boost - simply buy better actuators or a EBC.

As stated also, not sure why you have a reg on there, serves no purpose.

cool as for the fuel reg a havent fitted but i thought the injectors would

of run out early but it appears not so ill leave it off

thanks

I've seen 250kw can be made with stock turbos at 1 bar & cam gears with an agressive tune.

I only recommend Nistune is because it's a cheaper solution, it's a daughterboard that is installed inside the stock ECU which unlocks realtime tuning. You could sell the PFC and the money you got from selling it can go towards getting Nistune installed and dyno tuned and still have some money left over for others things like cam gears etc.

If he has a PFC there is no reason to sell it.

You get what, $650-$750 2nd hand.

Then pay $150 or so for a new ECU, then the addon's etc, no point. He has the PFC, nothing wrong with it, use it.
