Max boost on a s15 t28 with stock injectors.

specs;Stock injectorss15 t28maxima mafssafc2, ca16de jwt ecu, fmic, walbro fuel pump.

Since the new turbo has more flow than the stock ca t25, i was wondering whats the max i should be boosting at. 10psi on this one would be equivelient to higher boost on the t25 because of efficicency and flow.I assume 10psi, but id like to hear from anyone who has experience or knows. I expect it would be round about the same as a s14 t28.

Right now walbro pump isnt in so its staying @ 7psi.

thanks

yeah....10 MAX. Personally, I would run it as low as possible until I could get it on a dyno with a wideband to see your A/F ratio is.

the walboro/370's combo runs pretty rich stock...so u should be fine between 7-10psi...but like c-rad said get on the dyno or find someone w/ a wideband and checkout those afrs....good luck

ca16 ecu???

I'm running 12psi with a S15 T28, RB25 afm, stock CA turbo pump, injectors, intercooler and ecu tuned with a SAFC. It is still a little rich but I won't run more boost until I sort the fuel system and intercooler. Fitting the large afm required the addition of a lot of fuel to get the air/fuel ratios right, it was very lean so get yours tuned asap.

car is already running pretty rich right now.i could also richen up the mixture with afc if needed.10psi it is for now tho.
