Been told and looking for information on the MALPASSI FUEL PRESSURE REGULATORS

basically is anyone using these on turbo cars and what are the results?

my engine builder and tuner have strayed me away and told me not to use it as it stuffs around with your A?F ratios too much (ie. 3 runs on dyno same tune and 3 diff A/F ratios?)

can anyone confirm this and give me info and results if you have used them

Thanks

Have useed them in the past to get more power out of standard injectors, the pressure has to be setupm as it isnt out of the box. There are three different models, 1:1, 1.7:1 and 2:1. no problems with varience on the dyno. i dont understand why do you need one?

i bought one cause i've just turboed my na and havent upgraded the injectors but a little extra pressure will make them flow a little better as i dont quite need to replace the injectors just yet, putting it on on friday when the car goes on the dyno. ill see how it goes.

i think he was refering the n/a injectors to my post earlier, and i didnt pick up stock injectors cause right now i dont need them for the car, im planning on upgrading the fuel rail 550ish injectors high flowed turbo cams bigger cooler and prob a head gasket in about 6 months and who knows what condish the second hand injectors are in at least i know mine are good and up to the task im asking of them right now

    • Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure
    • Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.
    • Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15  
    • Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.
    • 8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
