Sump_slammer 23 Posted March 8, 2015 Report Share Posted March 8, 2015 Hi what are people running for injectors and fuel pump wise on turbo 12 valves? I've got a garret gt3582r turbo so I'm sure it'll get enouph air but I'm after a decent fuel set up now. I know theres the Walbro 255 and bosch pump but was wondering if anything is now the done thing. want a set up which will have room for improvement in the future. I hear Siemens are now the in thing?? Link to post Share on other sites
ibs 308 Posted March 9, 2015 Report Share Posted March 9, 2015 I'm currently running 440cc injectors with a standard fuel pump without any problems but I have ready to go on a "fuel performance" pump and siemens 630cc injectors. Link to post Share on other sites
Sump_slammer 23 Posted March 9, 2015 Author Report Share Posted March 9, 2015 Do the siemens injectors have the same plug? Or do you need to change the plugs? also the inline fuel pumps wheres the best place to put them. Link to post Share on other sites
ibs 308 Posted March 9, 2015 Report Share Posted March 9, 2015 The Siemens do use the same plug. Not sure on inline fuel pumps the one I'll be using is an in tank one. Link to post Share on other sites
RBPE 198 Posted March 10, 2015 Report Share Posted March 10, 2015 (edited) Custom Black Ops spec 750cc's - fastest on the market. We're in discussions about making these direct fit for the 12V VRT's too at the moment as they need wiring and fitment mods for the 12v. They do the Blue Knights now to for the 12V but I think those are ME7 mk4's the US got. Under the car is usually a good place for fuel pumps, keeps the noise down and gives them a bit of air flow - the Deatschwerks surge tank/fuel pump combo is out soon and will be testing them out too!

Sump_slammer 23 Posted March 17, 2015 Author Report Share Posted March 17, 2015 (edited) Deatschwerks surge tank? is this in fitment to a standard tank or is it a fuel cell in the boot job? Edited March 17, 2015 by Sump_slammer Link to post Share on other sites
RBPE 198 Posted March 20, 2015 Report Share Posted March 20, 2015 Similar to the IE one - Mike Deatsch told me they would be out first quarter in 2015 last year.

RBPE 198 Posted March 20, 2015 Report Share Posted March 20, 2015 P.S. DW do in-tank for the mk4's which are the ones we use, the 65V as they are called but as far as I am aware not for the mk3 based cars. Link to post Share on other sites
FishWick 21 Posted March 31, 2015 Report Share Posted March 31, 2015 I used Mazda RX8 injectors and the usual Walbro 255l/h drop in. That lot was fine for 400hp and those injectors had the best atomisation available at the time (circa 2010), which is important if you want a smooth idle and low speed manners with short runners (slower gas speeds at low rpms). I also tried an IE external surge tank with an 044 in it and it was noisy as hell, but such things are subjective I suppose. Link to post Share on other sites

I like the Black Ops injectors, they're 4 hole pintle's too so really good atomisation - quite expensive though. Apparently they do them in direct fit but I am sure they were the thinner EV6 style they showed me but according to 5-O they are direct fit for the VR6's. These are the dead times for the more popular injectors used; Edited March 31, 2015 by RBPE Link to post Share on other sites
FishWick 21 Posted April 1, 2015 Report Share Posted April 1, 2015 Don't have the car anymore but I left it with the RX8 injectors (500cc Densos) and the Walbro drop-in. The idle quality with those, Schimmel 263 cams and his short runner was the smoothest I've ever experienced on any 12V engine, standard or otherwise! Not familiar with the Black Ops, I've been out of the game for a few years now. Are they a modified EV14? I did try some 550cc EV14s (modded by US tuners, not direct from bosch) and below 2ms, they got a lil lumpy in the idle, so I had to increase the idle speed to 850rpm to hold 2ms and a smooth 14.7 AFR. That's the problem with large injectors and the way they drop off their linearity sharply below 2ms. Good injectors though! Link to post Share on other sites
