13PSI boost my car strart bucking

[Darius2250]

So I have been fighting this issue of when my boosts hit around 13 psi the car just starts bucking like it is hitting fuel cut or something. I am running the stock turbo,stock maf, stock injectors, stock fpr and fuel pump. today I tore out the turbo to replace it with and SR turbo, but couldn't get one of the bolt loose to reclock the housing so it would fit, however in the midst of the tear down I found 2 things wrong, the turbo to manifold gastket was blown out completely from one corner and my O2 sensor was only in finger tight, I am not sure if either one of these could cause this issue or not though. any ideas?

Thanks

if you were still runnig stock everythinh....then you most likely were hitting fuel cut ( aka boost cut )

well I have a Maxima MAF and 470cc injectors I can put in will that help or do I need to change the injector,maf,turbo and fuel pump?

[datsunboy]

yeah that'd help if you were hitting the stock fuel cut.you will need to get your ECU reprogrammed for the MAF and inj tho.you wont need to change the turbo....but since you already have a SR one, you may as well put it on there since its better!noy sure about the fuel pump, as I have never used a standard fuel pump before

it does sound like fuel pump issue to me. Those stock fuel pumps are worthless when you start cranking up boost.

13psi on the stock system if the boost/fuel cut. You need to have the ECU reprogrammed to eliminate the various cuts and be able to use the Maxima MAFS and injectors.

thanks everyone, I been trying to find a place to get a chip, I was looking at the N60 Mafs I have and well I have the plug no wires I tried looking for a wiring diagram but can't really seem to find one. Figure I would just pin it with the CA MaF pins, can somebody help me?

ABCDEF - n60ABCD - Stock CA

Also I am running an SAFC 1 (not the old dial style)
