dangerous brain Posted February 18, 2008 Share Posted February 18, 2008 OK I am attempting to identify my injectors. Short of taking them out is there any way of figuring out what they are? They are pink in colour which is apparently unusual. They are fitted straight into the standard rail and don't appear to have a set of resistors so same impedance as JDM. They were supposed to be 650cc injectors of some sort. Now Arnout said they looked a bit like the ones in the VVTi TT but they are 430cc. Why would anyone ever fit those in place of the stock 440's? Also for the car to run sub 10 rich afr on boost if they were indeed 430cc injectors would that not mean the fuel pressure would have to be ridiculous? Anyone have any thoughts or ideas?

Wez Posted February 18, 2008 Share Posted February 18, 2008 PE 650cc are yellow, the 800cc are a brown, look here for PE colour schemes :- http://www.powerenterpriseusa.net/products/fuel/injector/index.htm Quote Link to comment Share on other sites More sharing options...
SimonB Posted February 18, 2008 Share Posted February 18, 2008 Have you got some sort of fuel controller? When I put my 650cc ones in the car wouldn't even start or run until I trimmed them back with the Emanage it was that rich, so unless you've got something controlling them I doubt they are 650s. They're not power enterprise, those are white for 550s, yellow for 650s and brown for 800s. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted February 18, 2008 Author Share Posted February 18, 2008 I am using an AEM to control fuel. Before that there was some sort of HKS Fcon in there fudging the factors. Like I say these ones are pink. Quote Link to comment Share on other sites More sharing options...
SimonB Posted February 18, 2008 Share Posted February 18, 2008 Could be any size then I guess. Only other ones I know of that fit the standard rail are blitz 850cc ones, they are red I think.

dangerous brain Posted February 19, 2008 Author Share Posted February 19, 2008 Ah right I was told there are a bunch of 650s and 720s that will drop straight in. Wether or not they are pink is another matter. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted February 19, 2008 Author Share Posted February 19, 2008 Right I have popped one out now. Its definitely very pink. There is no manufacturer stamp or even an inkling where they were made embossed on them apart from what looks like a three double spoke wheel on one side. There is a number 5 embossed on the opposite side to the wheel. There is a number etched on the metal section G827 then 227 There is a D embossed on the plastic of the inlet strainer housing. Also does anyone have a number for the small o ring seal as the one on this injector looks a little perished? This one is pointing at where the wheel is embossed http://clubaristo.net/forums/imagehosting/2447bab9164aa89.jpg This one is pointing at the embossed number 5 http://clubaristo.net/forums/imagehosting/2447bab917263ff.jpg The etched on numbers are in this one on that metal edge http://clubaristo.net/forums/imagehosting/2447bab917f38a7.jpg http://clubaristo.net/forums/imagehosting/2447bab919247cd.jpg http://clubaristo.net/forums/imagehosting/2447bab919b7b38.jpg Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted February 19, 2008 Share Posted February 19, 2008 They look like Denso 540cc injectors (these are Red and fade like yours). They are used in the Rev3 3SGTE engines and in the UK spec 2JZGTE but not sure if they are red in the Supra's. Denso 540cc's are Low impedance so do you have a resistor pack fitted?

dangerous brain Posted February 19, 2008 Author Share Posted February 19, 2008 Where would a resistor pack be fitted? Its not something that I can see chopped into the loom. These don't look faded they are all an equal sort of pink and quite a light pink that IMO would not have started out as red. Other than having it flow checked what else can I do? BTW how expensive is flow checking an injector? Quote Link to comment Share on other sites More sharing options...

dangerous brain Posted February 19, 2008 Author Share Posted February 19, 2008 OK its looking like I might have to go that way. I just called a guy that specialises in cleaning and testing injectors and he said it would be incredibly difficult to test an injectors actual flow rate. He'd have to know the exact miliseconds they are meant to open the impedance and the fuel pressure they are meant to operate at. How much are a set of drop in 650cc or 720cc injectors?

Wez Posted February 19, 2008 Share Posted February 19, 2008 How much are a set of drop in 650cc or 720cc injectors? If you buy some PE injectors from the US they work out pretty good at the moment, what are your goals HP wise as I have 650cc and they are pretty much maxed at 560hp. PE do some 800cc drop-ins which would be better if your goals are higher than 560hp. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted February 19, 2008 Author Share Posted February 19, 2008 My goal is to get my car running properly lol. I am having sneaking suspicions that these are low CC injectors with ridiculously high fuel pressure. Wouldn't surprise me to find a stock fuel pump busting its guts in there. Would it be possible for say 430cc injectors to have enough fuel pressure to feed a t67 turbo at 1.0 bar of boost pushing out around 470 bhp and be running AFRs of lower than 10's What sort of pressure would we be talking about here?

dangerous brain Posted February 19, 2008 Author Share Posted February 19, 2008 Could it be this one? http://www.sardracing.com/images/products/63564_small.jpg Thats a denso SARD 800cc (SR63564) Side Feed / High Resistance 2 Holes / Oval / 1.60msec Looks almost identical.

dangerous brain Posted February 19, 2008 Author Share Posted February 19, 2008 Bump any one think that the sard 800's are the same ones? Quote Link to comment Share on other sites More sharing options...
Dragonball Posted February 20, 2008 Share Posted February 20, 2008 They look to be the same ones as I have in a rail here I believe these are VVti 440's Numbers on the top (very small) 8F23 and 23250-461000 Just found this on search http://www.mkivsupra.net/vbb/showthread.php?t=71948&highlight=23250-461000 Quote Link to comment Share on other sites More sharing options...

Paul thats exactly what Arnout in Holland said. If its true then my fuel pressure is up in the sky somewhere. I am not sure though why a tuning company would replace the older injectors with VVTi ones especially as the car was singled in and around 95-96. PS thanks for your contribution as I know our last communication wasn't exactly friendly. PS theres no numbers on the top at all though. Only markings are as I described.

Robert Posted February 20, 2008 Share Posted February 20, 2008 i would have thought that maybe as a demo car it would have had the correct injectors but later along the line after do luck sold it they could have been changed? can't the AEM read the fuel pressure mate?

Robert Posted February 20, 2008 Share Posted February 20, 2008 if you want to send me your map i would be happy to have a look see. Quote Link to comment Share on other sites More sharing options...
Dragonball Posted February 20, 2008 Share Posted February 20, 2008 Sounds like there is real hope yet - the Denso's def have markings No probs m8 Stress is a terrible thing - and I have my pills now! Good luck with them! The flow holes on yours look much larger than these 440's - cant tell much mnore from the pic Quote Link to comment Share on other sites More sharing options...

Ah see now Do-luck/sumo didn't do the turbo conversion the guy that bought it from them did that. If you see the pictures on the do-luck site you can clearly see that it has fog lights fitted and no FMIC. As for how the job was done most have said that it looks like a tidy and professional install but that doesn't guarantee cheap components weren't used. To be honest though I really can't see why they would take out 440cc injectors to replace them with 440cc injectors. I don't know if the AEM can read the fuel pressure. Is it a simple job to fit a fuel pressure gauge? Paul I should also apologise for my lack of tact and bullheaded attitude, got any spare pills Quote Link to comment Share on other sites More sharing options...
Robert Posted February 20, 2008 Share Posted February 20, 2008 should be simple to fit a gauge onto your FPR. Quote Link to comment Share on other sites More sharing options...
Nic Posted February 20, 2008 Share Posted February 20, 2008 SARD do an 850ccc side feed, high impedance injector for the 2JZGTE that is described as red/brown in their catalogue, part number 63507. http://www.sardracing.com/products/Injectors.htm Quote Link to comment Share on other sites More sharing options...

BTW how expensive is flow checking an injector? The Resistor pack would be on the back firewall probably. To Check the impendance of the injectors which would make life easier for finding out what injectors they are, pop a Multimeter across the 2 two terminals of the injector and measure the resistance. Under 6 Ohms they are low impendance over 6 ohms they are high impedance. Report back Ryan Quote Link to comment Share on other sites More sharing options...

Report back Ryan 12.6 Ohms chap The more I look at it the more I am convinced its this one you know 800cc (SR63564) should be simple to fit a gauge onto your FPR. How do I go about doing that chap?
