I have now received all the pumps and am now awaiting payment. If i do not receive your payment by wednesday i will have to send your pump back to bosch. On that note i have at this point 1x040 and 2x910 spare so any one interested give me a yell

hey guys,

have any of u who bought the bosch 910 pumps installed them yet?

I needed to know if they are loud?

Also, are the bosch 975 pumps much better?

(I'm aiming for 190 - 200rwkws and was told to get a bosch 975 pump, but it only flows a little bit more than a 910 but is a lot more expensive, why is this?)

sorry to hijack but any info is much appreciated.

Thanks heaps!!

A 910 will support up to 335 rwkw which will be ample for you

I'd like to know how you worked that out ?

BHP is the HP measured at the flywheel. Now using my formula below this is what I'd rate those Bosch fuel pumps.

Formula = BHP x 0.746 (hp -> kw) x 0.8 (using a 20% drivetrain loss which is quite conservative) = rwkw

So that means:

910 rated at 450 bhp = 335kw = ~269rwkw

040 rated at 520 bhp = 388kw = ~310rwkw

044 rated at 730 bhp = 545kw = ~435rwkw

I'm personally using the 040 pump.

Sorry calculation error on my behalf didnt allow for the 20% drive train loss. The bhp is still correct so people could have worked it out from there.

Give me a break im doing a favour getting these pumps cheap for you sau guys making no profit for my self.

Was there an 040 left? If so I'll take it but Im outta town til after Xmas.

nah sorry, there are only some 044's and 910's left but I will be sending them back to bosch if they're not purchased by Wednesday (tomorrow).

    • Welcome. This is not really true. We have a whole forum here just for the NA shitboxen. And they are not very different from the turbo shitboxen. Just weaker brakes and gearboxes, and no LSD, for the most part.
    • I'm pretty sure it has an 040 in it @Duncan Also reading up, that turbo should top out at 250 as you first thought. It will be interesting to see how early it chokes due to the changes in the head too
    • Yeah confirmed they are Nismo 555s, found the boxes in the spares with the factory injectors in. Yeah the AAC has been relocated to allow reuse of the factory brake booster line, and yes confirmed it has a 1 way valve in it. Unfortunately the one on the car is cracked, I'll need to replace it. Pretty sure I've got all the AAC plumbing correct in my previous post, but I am going to source some new fittings with 90o angles to help with the hose routing and also one really specific moulded shape for the AAC intake to cold start hose (will raid the back of our local repco when I get a chance and work out some combo that works) One of the big things I learned in the GTR is you need to be able to get your hands all around the bay when something goes wrong. I've done a bunch of re-routing now and it should be much more practical now. Also got the BOV mount re TIG-ed by the local engineering shop so that should be good to go now. Never got to the fuel pump because of some life stuff today, but will pull it to confirm it is suitable for 300rwkw when I get a chance
    • Hello everyone, I am from Malta and have recently bought myself a fully stock 1992 Nissan Skyline GTS. It has the RB20DE engine and thus is NA. Unfortunately, not a lot of information can be found online related to the GTS, unlike the information for GTS-T and GTR variants. Apart of the Skyline, I also got a 1984 Porsche 924 2.0l NA and a 2002 Renault Clio 1.5DCi for everyday use. Excited to be apart of the community and perhaps get better information on cars such as the GTS.
    • The fuel pump bracket just slides straight up.  Below is a pic I stole off a site. But basically put hand in for fuel pump, wiggle it all about a bit while pulling up.
