New Fuel Pump! Is It Needed Near 200rwkw?

[r32matt]

Hi,

My R32 Skyline is reaching near 200rwkw, when i got it dyno tested it was running a bit lean in the high revs. Would I need a new one when im reaching 200rwkw? Will the standard one not be enough?

Thanks

[R33(00) (00)]

yeah man defenatly need mines running 198rwkw and it has a 400psi fuel pump would be a good opption and some new injectors if u want to go all out

im not sure about r33s but im reaching 220rwkw with no problems....

[R33GOD]

definately change it. if it was a r33 then id say no

i would be changing it simply due to age of the pump, but also i think the stock one would be at it's limits.

new fuel pumps are cheap and take about 1/2 hour to install yourself

like every one else said.. replace.. your at the limits of the stock one and its old.

Ok cool, sounds like I should get a new one! lol

Might get one installed today while its in the workshop.....

My mate said he can get me "JR coilpacks", has anyone heard of them before? Ive tryed doing some research on google but cant find anything. Or would it be best just to get Splitfires?

Best to change it man.

WALBRO fuel pump is like $130ish, very good pump. I think there is someone with an R33 making about 300rwkw with one?

GTR pump is also a good upgrade. Its a similar price to a WALBRO pump, but 2nd hand obviously. There a good size pump and will serve you fine.

BOSCH 040 pump is a slightly larger pump, but worth more like $180. Also a good brand pump good for big power.

Personally running a GTR pump and aiming for about 220-240rwkw which I think it should be fine with.. But I only bought it because I got it cheap.

Would go with a WALBRO if I did upgrade as they are good value for money, just make sure you get an original one.

Just my input, hope it helps.

Oh and just a quick input about injectors. They will be fine to about 215-220rwkw, once you exeed that or get near that its recommended that you change them as they get high into the duty cycle, which means there more prone to failure.

R32 GTR injectors are a good replacement, but for a few hundred more you can grab a new set of NISMO 740cc injectors, about $500-$600.

just think about how vital it is to keep a nice flow of fuel in your car.. change it asap.

i personally wouldn't change your 15 year old standard pump with a 15 year old GTR pump.

if you're really after GTR type, get the nismo pump. if you want your money's worth, get a bosch 040.

change the injectors too. i wouldn't feel safe keeping them close to full load.

that's my 2c

If you dont have ignition problems, then you dont need any.

When you say ignition problems do you mean when i start the car? Becasue everytime i start the car i need to touch the pedal a bit to get the fuel going through? Would this be the fuel pump or my injectors?

With the Coilpacks, i wanna get some new ones as every now and then the car will start miss firing, but then it will be ok for awhile..... Think im gonna go for the JR coilpacks, they are new for $400. Spilfires seem to be $700... bit expensive.... Has anyone heard of the JR coilpacks?

Splitfires are $550 delivered from our traders.

Get those, proven to work

[heller44]

..or get the other ones and play guinea pig for the rest of us..

It'll be okay to run your standard injectors at 215rwkw+ aslong as you've got a good tuner. I think it'll be best to change your injectors at 200rwkw though.

Like everyone else has said about the fuel pump, just get a new one. Don't replace a 15 year old pump with another 15 year old pump.

don't start pulling the cash out yet.. try a couple things.

for starters, have you taken off your spark plug cover? with it on it traps the heat inside which can make your coilpacks go funny.

second, try doing a coilpack diagnostic check to see if they're up to scratch.

and third, slap some injector cleaner in. see if that helps.

Fair point!!

Might just order my self a new fuel pump right about noooww..

[aphid]

Best bet would be to change them out before they do go, as the density of compressed air/fuel in the combustion chamber increases, so does resistance, putting more load on the coil packs which will eventually cause them to fail

Splitfires are proven to work but they're also a rip off.. If you're handy with electronics it doesn't take long to wire up 3 bommodore coil packs in a wasted spark type setup

If you dont have ignition problems, then you dont need any.
