jtmny1999 Posted August 15, 2008 Share Posted August 15, 2008 I have 2 quick questions. I have rb25det series 2 on my 240z and I just got it running with the stock 280zx turbo fuel pump, you think it will give it enough fuel pressure to drive? Also anyone think I will have any problem using the series 1 MAF on my series 2 motor? I got the wrong Maf at the moment..... Any help will be appreciated. -JT Quote Link to comment Share on other sites More sharing options...
jakeoster Posted August 15, 2008 Share Posted August 15, 2008 If your talking about the original fuel pump that came with the Z then no, I wouldn't recommend it. Itd be best to get a new one. I have to buy one myself as I am swapping an RB25 engine and am not sure which one to buy. Quote Link to comment Share on other sites More sharing options...

ZDrifter Posted August 15, 2008 Share Posted August 15, 2008 I got a walbro 255 off of ebay for 100 bucks. Brand new and it was walbro brand. Works great. Quote Link to comment Share on other sites More sharing options...
Careless Posted August 16, 2008 Share Posted August 16, 2008 how loud are the 044's? I was in a car recently with what the driver told me was a bosch unit, but did not know if it was an 044... and it was kinda loud. perhaps fastened to the frame rail without bushings of any sort? it was irritating if u listened for it. and once you found the pitch with your ears it was hard to shake off.
