R33 Gtr Fuel Pump In My R32 Gts-4

[OMGGTR]

Hi guys, used search b4 i decided to make a new thread, but dident quite find what i was after so here it goes!

today i went to Dr drifts dyno day..

jumped on the dyno and initial run i was told the cars running way to lean and its to dangerous to run so i waisted 50 bux for nothing lol

he told me fuel pumps f*ked (standard rb20 one) so i went on home and fitted a r33 gtr fuel pump took me about 15 mins to do it and it all fitted perfect with some slight modifications.

car runs awesome... and all went well... but ITS WAY TO LOUD! like... people driving next to me can hear it....

now i know its not vibration its just the pump sound.... could this be that voltage problem ?

what do i do ?

Mounted it incorrectly, only reason really.

The pump shouldn't be "that" noisy at all.

Although given you've made no mention of any wiring changes (which are required), then that's also a problem.

hmmmm ill just have to pull it out and take another look... ill get back to u, hope its not to do with voltage.. so cbf with electronics i hate it

Wiring changes? theres a positive and negative .... did i miss something?

bah nismoid can u link me to a DIY if there is one? or shed some light on what needs to be done... some 1 was telling me to hook up a relay n straight to the battery? something about r32 voltage drop on idle....

i did a GTR pump in my r33 and its basically silent if mounted properly

you can hear an ever so slightly pump whirr when you tap the throttle but thats it

certainly you wouldnt be able to hear it outside the car

id say its hitting metal or something

when you mounted it, did you slide it back into the same spot, using the ceiling slide mount thingy?

yeh man... look i may get rid of the sound... but shit i duno whats happening if i rev up now 3k upwards the car feel like its building up a lot of pressure and the revs go down as i accelerate... and i loose a lot of power ???? i hope i dident do damage... so i been just baby shifting all day till i get it out...
