Nismo Fuel Pump Rewire?

[RB2600]

I have searched, perhaps my skills in doing so aren't quite up to scratch but have done so regardless.

http://www.skylinesaustralia.com/forums/topic/218752-nismo-fuel-pump-for-32-gtr/

So I plan on using a Nismo pump in a 33 gtr, to my understanding, they flow 276L/h @ 12.5V

Stock wiring to fuel pump generally does not see 12.5V does it?

Therefore I'd like to know if it is just as important to rewire for the Nismo as there was no answer to

a similar question in the above thread.

Absolutely. Run a new wire from the battery and a relay. Make sure the wire is 6mm and just trigger the relay from the stock power feed.

when I installed a tomei My fuel pressure doubled just with a rewire...hit nearly 6 bar....

This may be a dumb question but what would happen if I was running a stock reg that's not adjustable?

Oh and here, tutorial might help

Thanks for clarifying, so it can be done exactly like so on an R33 GTR right?:

It's a little bit confusing because the below diagram seems to teach a slightly different method (or is it the same?):

Is there one method which betters the other?

The former (NARVA relay) seems easier.

[ARTZ]

Yeah I found the narva relay one the easiest..

Beautiful, thank you ARTZ.

sorry, question is not about nismo and gtr33, but should i rewire GTR34 pump when install to R34 GTT?

[33GTRV]

When i rewired the fuel pump in my 33 GTR (nismo unit) i rewired the WHOLE thing. I got rid of the fuel pump speed controller, ran new earth and new feed and relay with a fuse in line, cost me about 50 bux in parts(heatshrink, solder, relay, inline fuse holder, some QUALITY terminals)

I did the re-wire yesturday. Hopefully this will help

That just looks like a standard relay setup.

[89CAL]

The original runs through the controller etc...?

[The Dan]

No I mean the diagram just looks like a standard 5 pin relay setup. Nothing special.

Or was the purpose of the diagram to explain how a relay is wired?

[kitto]

I hope theres a fuse between the battery and pin 30 on the relay.

try this

I know there is one spacific for the R34 GT-Rs but I don't think this is a spacific one

Oh yeah just to put it in a drawing. I found the DIY a biit confusing (where its just written) so thought I'd do a diagram that shows how to do it with the R33 wiring. Its a basic circuit but might help the OP. Only problem I had figuring it out was working out the positive feed because I didnt have anything to test it so just made up a test light. And yes forgot to add the fuse in. I have a 20amp fuse between battery and relay Edited August 30, 2012 by 89CAL
