Jake Mcaulay 6 Posted September 14, 2015 Report Share Posted September 14, 2015 Hi guys.After some advice on injectors.Going to be running a rotrex c30 94 on my vr6 soon and just getting all final bits together before bolting it up.My question is what injectors do people recommend?! The charger is currently running 8psi as standard, in the future I will look at running more.I'm aiming for around 300 - 330bhp so need injectors to suit.I've read about red top and green top but have read that the spray pattern on the EV1 is pretty dated now, this correct?!Are ev6 better with the ev1 adaptor?!What else are people running?!Does anyone have these for sale or know any sites to get them?!Much appreciatedJake Dave_ciw and VR6Pete 2 Link to post Share on other sites
Dave_ciw 507 Posted September 14, 2015 Report Share Posted September 14, 2015 Just bought some siemans 630CC injectors to run on my turbo conversion. A big choice is the Bosch 440 Big Greens tried and tested for years! Got my 630s for £240 delivered from a UK company... D11PS 1 Link to post Share on other sites
Jake Mcaulay 6 Posted September 14, 2015 Author Report Share Posted September 14, 2015 Thanks Dave. I'm no expert on injectors, 630cc a little too big?! Can be mapped down but enough?!That's a good price, where from?!Yeah green are tried and tested but just heard there are far better nowThanksJake Dave_ciw 1 Link to post Share on other sites

Here is a link dude, I also went for my fuel pump from these guys to £80 and lifetime warranty boasting better figures that the Walbro. Benny is running a charger with that pump not sure on his injectors though. Pretty awesome build thread of his worth a read. It may be in there.

dave_424 48 Posted September 15, 2015 Report Share Posted September 15, 2015 (edited) What power you running Dave? Running 15psi at the moment with a GT35R turbo, so around 400bhp+ would be my guess. EDIT: Accidentally turned my best controller the wrong way and boosted to 22psi, injectors handled that fine but good god it was fast Edited September 15, 2015 by dave_424 daveyboy and Jake Mcaulay 2 Link to post Share on other sites
RBPE 198 Posted September 15, 2015 Report Share Posted September 15, 2015 Depend's on the injectors too, the 630's are quite old and slow compared with modern ones, I would prefer not to use them myself. I am a bit bias though as I have spoken to 5-0 about this for a few customers wanting vrt one's then these appeared on the market! http://www.ebay.co.uk/itm/6-1000cc-Fuel-Injectors-FLOW-MATCHED-VW-Golf-VR6-AAA-USE-E85-OXY-GAS-/261115795180 They look like they've modded/customized them the same way as the ME7 Black Ops one's we use for the mk4's, the latency times would suggest that. However you lot keep going the "money" route and go for the old 630's as them come in quite a bit cheaper with duties! Your tuners would prefer you to spend a little more though! Also, they gave me these times for generic 630/650cc USCAR one's they do compared with the Green Giant replacements and looking at the times you can see vast differences in them, it's why the old "they'll be really slow" argument is a little old hat now as you can see huge differences between same size and bigger ones being quicker than older smaller ones. Point being, get as much info as you can on them as no two injectors are the same! ky_uk and VR6Pete 2 Link to post Share on other sites

Not quite, that was on the site wasn't it? You should really always get a set of dead times/latency info with any set of injectors so you can map them properly - above it's the turn on time which says 1.14ms@14V - if you look at the list I put up the 750cc Black Ops we use for the mk4 are 0.587ms which means they are twice as fast at that voltage - i.e. can turn on twice as fast and the custom USCAR 630cc ones are nearly 4 times as fast at 0.35ms. Some people will just mash the times on a tune so it runs right and you could get some decent idea from searching for a list like that as to what the times are for a better tune but you ideally want a copy for any tuning. So it's the turn on time for all the other voltages I am after to add to the list really, I would think the shop had them even if thy didn't give you them? Link to post Share on other sites
Dave_ciw 507 Posted September 17, 2015 Report Share Posted September 17, 2015 I can email them and ask dude. What your asking is far beyond my knowledge I will check any paperwork supplied. Wasn't opening them until Michael sends me the lower intake he owes me so I can mount them straight away. Link to post Share on other sites
RBPE 198 Posted September 17, 2015 Report Share Posted September 17, 2015 Added that bit - these are all VR6 mk3 and mk4 V6/R32 injector fitments by the way to show the options. Link to post Share on other sites

Wasn't opening them until Michael sends me the lower intake he owes me so I can mount them straight away. No worries, thought they might have given you a list. Oh and dead times/turn on times are just how quick the injectors turn on and off as they never continously fire out fuel. Edited September 17, 2015 by RBPE Link to post Share on other sites

Also on the end I've decided to add Water - Meth system (AEM) and a boost gauge. Edited February 16, 2021 by bluemotion Link to post Share on other sites
