Fuel Pump + Press Reg

[gtst25]

Gidday fellas,

I'll soon be purchasing a big pump + adjustable press reg for a series 1 r33 and am interested as to what people are using on their '33s.

Got in touch with a company called Powerflow awhile ago and got some good prices on in tank bosch 044's.

I've seen a few press regs in nengun's site - one there looked good which is a nismo item - adjustable and looks very similar to the stock '33 unit.

(great price too!) Just wondering if anyone has purchased one of these and are happy with the result?

Anyone use any other products/can recommend anything for me?

ie Sydney kid with that r34 that made 265rwkw?

Thanks!!

Have you got aftermarket injectors, or are you using the standard ones.

Yep, I have a Nismo adjustable fuel pressure regulator that came from Nengun, it bolts onto the end of the standard fuel rail, I'd say $180 well spent.

ive got a walbro... making 273kw @ the rear end.

its maxed out so get the 044... thats my next upgrade... never planned to change turbo's so ive got to go bigger.

still using my stock fuel reg

I've used a Malpassi reg., seems to work fine on mine. I've used the standard fuel pump with an external Bosch 911 to make 450rwhp, but now have an 044 to push past this figure, it's running from a 3lt surge tank.

Hope that helps

Im running a larger bosch in tank pump with a malpassi adj fuel reg. 248@rear out of stock injectors....works well....(yes im in the process of getting 840cc items from japan, i know stock items arnt intended for this power).

there are many different brands and options, my advise would be to go with what whoever is tuning it is recomending and familiar with....

Thanks for the replies.

Looks like I'll order the nismo item and 044 pump.

I've been told there's two different inlet sizes on the pumps in the '33s - has anyone else found this?

The injectors i'm running at the moment are stock but I plan to get some nismo 740cc ones in conjunction with a turbo upgrade after we tune the pfc, but that'll be awhile away.

Still waiting on the pfc but when we dyno I want the fuel system up to scratch as it was leaning out last time with stock boost/computer.

Anyway - hope to post up a dyno graph soon!
