Nex 17 Posted July 13, 2012 Report Share Posted July 13, 2012 Ok just after a little info, what bhp are the injectors and fuel pump rated to on the 4mo's?So l guess the question is, theoretically at what bhp would you say you would need to upgrade the injectors and pump? Thanks in advance Link to post Share on other sites
bungy 2 Posted July 13, 2012 Report Share Posted July 13, 2012 Depends what your plans are but I'd say they are matched with a small safety margin. The way I had it explained to me was like this:-For injectors it is easier to map a larger injector to open and close quickly than to struggle to open a small one for long enough.I have 630cc injectors and when needed a 300ltr/hr pump.

Nex 17 Posted July 13, 2012 Author Report Share Posted July 13, 2012 cheers Bungy, that is very helpful!I am just working on a possible plan to go FI at some point and just trying to get some of my facts straight Link to post Share on other sites
bungy 2 Posted July 14, 2012 Report Share Posted July 14, 2012 One thing to consider is the 12v injectors are easier and more numerous to find. A 12v injector loom grafts straight on and gives you more choice and cheaper. Link to post Share on other sites
Nex 17 Posted July 14, 2012 Author Report Share Posted July 14, 2012 legend! cheers dude will keep that in mind I was looking at the Ev6 440cc green top injectors as l believe they are direct fit, but will have a look at the 12v setup too and might have to look at slightly big injectors as well lol Link to post Share on other sites
bungy 2 Posted July 14, 2012 Report Share Posted July 14, 2012 Are you going charged or turbo? Link to post Share on other sites
Nex 17 Posted July 14, 2012 Author Report Share Posted July 14, 2012 Turbo just trying to work out price and suppliers ect.. at the moment but its looking good so far, although my brain is melting lol Link to post Share on other sites
spadam 7 Posted July 14, 2012 Report Share Posted July 14, 2012 Are 440cc big enough. I was looking for 630cc same as Mark. Got my 12v injector loom. I assume the car is not drivable once you fit 630cc injectors as i would need to drive to get it mapped sonewhere. Link to post Share on other sites
Nex 17 Posted July 14, 2012 Author Report Share Posted July 14, 2012 I thought they might be till bungy explained it now l will be looking for some bigger ones lol looking at some from deatschwerks at the moThats a good point dude, because if l cant drive it to get it mapped l will have to sort out a mate to trailer it for me :/ Link to post Share on other sites
craggsy 91 Posted July 14, 2012 Report Share Posted July 14, 2012 I think mine are 550 genesis ones but would need to check paperwork Link to post Share on other sites
Nex 17 Posted July 14, 2012 Author Report Share Posted July 14, 2012 Would would be ace cheers craggsy Link to post Share on other sites
craggsy 91 Posted July 14, 2012 Report Share Posted July 14, 2012 Yes mine are Genesis 550ccs Link to post Share on other sites
bungy 2 Posted July 14, 2012 Report Share Posted July 14, 2012 Mine are big but give flexibility. Another thing to consider is how you get calibrated for your mpg reading. Unless this is changed to suit it will be out by the factor of your injector size difference. What turbo manifold are you going to use? Link to post Share on other sites
UnitedMotorsport 55 Posted July 14, 2012 Report Share Posted July 14, 2012 Just so that you guys know. The 2.8 and 3.2 head has different injector fitments.60lb injectors are a direct fit to the 2.8 with 12v injector plugs.52lb injectors are a difrect fit to the 3.2, again the connectors need to be changed.The ECU calibration will need to be changed to cater for the injector size, for fuel and fuel consumption calculations.If your going FI, don't even bother with stock injectors, you are wasting your time.Don't listen to the myth of, "bigger injector use more fuel all the time." If the ECU calibration is correct, injector size doesn't matter. Fuel usage is directly proportional to power, so a an engine producing 100hp is using the same amount of fuel, weather it has 20lb or 60lb injectors. Link to post Share on other sites
Nex 17 Posted July 14, 2012 Author Report Share Posted July 14, 2012 Cheers Craggsy. On a side note what boost controller are you using buddy?This is the one l have brought Bungy, nothing too fancy but will do what l need it to (l think lol)Cheers UM, I will be getting hold of you in the future for the mapping once l have got everything else sorted if that's alright? as l hear you are a coding wizard I have a hell of a lot to do before then mind :/ Link to post Share on other sites
Daverse 175 Posted July 14, 2012 Report Share Posted July 14, 2012 I smell another turbo thread! Link to post Share on other sites
bungy 2 Posted July 15, 2012 Report Share Posted July 15, 2012 Are you not going to keep the standard inlet manifold then and go short runner? Is that a T25 turbo flange? Link to post Share on other sites
Nex 17 Posted July 15, 2012 Author Report Share Posted July 15, 2012 I wasn't planning on changing the inlet manifold to be honest buddy, as l have heard it is good for up to 450 bhp and l will be running an intercooler which should help Yeah its a T25 flange but I will prob have to get it changed to a T4 flange or get an adapter plate made up as the turbo l want has a T4 On-Center flange, .85, A/R Turbine Housing, but will see what happens lolOn a side note has anyone on here had any experience with Remflex gaskets? It seems pretty good. Link to post Share on other sites
craggsy 91 Posted July 15, 2012 Report Share Posted July 15, 2012 Its not the amount of power that can kill the inlet....its the amount of boost Link to post Share on other sites
Nex 17 Posted July 15, 2012 Author Report Share Posted July 15, 2012 Uh ok with ya dude, lm not planning to run massive boost to start with but l will have a look to see what they are good for before a need to upgrade.You're still running a stock inlet right craggsy? Link to post Share on other sites
craggsy 91 Posted July 15, 2012 Report Share Posted July 15, 2012 I was told about a bar of boost maybe a touch more.Im running standard inlet with just under a bar of boost.Oh and to answer the boost controller question....I dont know what its running TBH Link to post Share on other sites
