GT28R and stock injectors? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Nismo240SX · 04-19-2005, 09:40 AM

i'm looking to buy a new GT28R turbo (s15) and run my stock 370cc injectors for the time being. i'm kinda just wanting to go with a HKS 12psi actuator, instead of going with a boost controller. i'm just wanting to know if the 370's will be running way out of breath with that turbo and that actuator. thanks.

SEARCH!! but you prolly should think about it again..You can run stock boost 7 safely

Nismo240SX · 04-19-2005, 12:38 PM

i've searched... i've found nothing. so 7 psi all i can get with 370cc's with the gt28r? i'm looking to get 550cc down the road and a jwt ecu upgrade, but not yet. just need a new turbo...

eyustfu · 04-19-2005, 12:58 PM

just keep it at stock boost around 7psi to be on the safe side, the 370s will probably max out at 12psi

i wouldnt recommend anything over stock boost being that that turbo is bigger and will push alot more air that a 25

Nismo240SX · 04-19-2005, 01:39 PM

true, i was going to get a fpr and bump up the fuel pressure and cheat... but guess i'll stick with stock boost for now

You can also buy those one injectors from deautchworks that are drilled out/rebuilt and flow around 600cc's and are cheap as fuck and yeah. 280 bucks or so I think for a set. I'm just stoked you called it the gt28r, most people dont. Oh, ps. Get a Enthalpy ECU, way better and I think cheaper. He has great tech service too.

Inland180 · 04-19-2005, 05:11 PM

It will run ok... but with some tunning it will run great!!

Nismo240SX · 04-20-2005, 07:50 AM

yeah, i'm going to prolly end up doing the AEM EMS

Nismo240SX · 04-20-2005, 09:17 AM

oh yeah, i forgot to mention... i have a Central 20 ECU

khoadogg · 04-27-2005, 05:08 PM

leave it stock until you tune that badboy! btw, can you run bigger injectors on a stock ECU?

touge factory apparently made a set of 550s that are CHEAP

i believe 350 for a set, sidemount for SR

Eternal_240Sx · 04-27-2005, 09:44 PM

i read in another thread that its just 370's and they drill it to make it 550's

What do most people call it? Are you thinking of the GT28RS?

sideview_180sx · 04-27-2005, 10:50 PM

gt28rs= disco potato........gt28r=not disco potato......BTW if you want to figure out about how big of injectors you will need use this equation (HP x BSFC(.5) x 10.5)/( # of injectors x .80(duty cycle) that shows youhow big of injectors you would need to make such and such HP.
