Noz Posted November 23, 2011 Share Posted November 23, 2011 (edited) What kinda boost are you going to be running dude? EDIT: seen your comment regarding 6-7psi. Assume your using standard injectors at that pressure? I'm sure you could run safely at 8psi with a good tune on stock compression. I've been told you have go just over 9psi but on standard compression its not recommended for long runs.

pjavon Posted November 23, 2011 Author Share Posted November 23, 2011 Ah good mate! There's nothing worse than somthing that small holding you back when your just about ready to put her back together Ain't that the truth:D What kinda boost are you going to be running dude? EDIT: seen your comment regarding 6-7psi. Assume your using standard injectors at that pressure? I'm sure you could run safely at 8psi with a good tune on stock compression. I've been told you have go just over 9psi but on standard compression its not recommended for long runs. Yes I'm leaving all that alone for now, I was just going to try and get it running nice on low boost and then MAYBE try for higher boost at a later date. It sounds silly I suppose but big power isn't the main goal, just hopefully a reliable car with a bit of go but we'll see;) Quote Link to comment Share on other sites More sharing options...
Supra_Scott Posted November 25, 2011 Share Posted November 25, 2011 I wouldn't recommend using the stock NA injectors as they will be pretty much maxed out with your proposed spec. If I remember right NA injectors are around 330cc so they are not running anywhere near maximum at stock BHP and have a big safety margin. My NA-T is running a dyno proven 374BHP @ 6psi boost which could be an issue if i had kept the OEM injectors. I went for some MKIII Turbo 440cc injectors. I paid a measly £60 for the six injectors off the MKIII Supra forum then had them ultra sonic cleaned and flow tested for peace of mind. They fit the NA fuel rail perfectly and are top feed unlike the MKIV TT side feed units. The resistance of these are lower than the MKIV NA injectors so i made up a resistor pack to compensate for this as it can affect open/close operating speed albeit not by much but this is your pride and joy!

pjavon Posted November 26, 2011 Author Share Posted November 26, 2011 I'm thinking of fitting one of these into my down pipe as I'm using cheap ebay stuff to try and eleviate any stress from the exhaust into the manifold. Anyone got any opinions, my view is it can't do any harm but thought I'd ask incase I'm wrong:D Quote Link to comment Share on other sites More sharing options...
-Welsh-Stealth- Posted November 29, 2011 Share Posted November 29, 2011 Really nice clean build! Subscribed really nice colour scheme! Looks the bee's I'm running stock injectors fine by the way but I'll be doing the same as gixer Quote Link to comment Share on other sites More sharing options...

I was thinking about the stress on the manifold without the flexi included. If toyota put it in, there's definitely a reason why. Let me know how you get on, as I need a new down pipe and could incorperate this if it works. Manifolds crack, this would reduce the chances enough to save you some pennies IMO. Good idea for sure! im going down the NA-T route so this will be great help looks great, cant wait to build mine Thought you were going TT? Turning to the dark side...

pjavon Posted December 3, 2011 Author Share Posted December 3, 2011 (edited) Started my oil feed at the filter end tonight. This is the bolt drilled And with the nut ready to TIG welded on tomorrow in work So it should look like this tomorrow night then I can connect my oil line up fully. Finished my oil feed this week so I mocked it up. I need to play with the oil line though as I can't get a nice arc in the line and it just isn't sitting right coming down to the oil filter housing. I think it might be a bit to long but I'll contemplate it for a while before I cut it and end up with it to short:D Got my BOV of StuartW on friday. I think it'll look much nicer than the HKS ssqv I had already bought but if not there the same fitting si I'll swap them over:tbup Edited December 3, 2011 by pjavon (see edit history) Quote Link to comment Share on other sites More sharing options...

pjavon Posted December 3, 2011 Author Share Posted December 3, 2011 Got my MKIII turbo injectors this week, I take it they fit the electrical connection if I sand these tabs off Quote Link to comment Share on other sites More sharing options...
Supra_Scott Posted December 3, 2011 Share Posted December 3, 2011 I would advise on getting the injectors ultra sonic cleaned and flow tested before fitting them. There is a guy on Ebay who offers this service, he did a great job on mine and took the NA injectors as part payment. I'm not sure on the injector plugs, gotta be worth a try. I went in far too eager and cut the plugs of to put the MKIII ones on. I'm liking the look of the oil return flange you have used, I used the TT one and blanked one side off, it doesn't look as pretty but it is functional. For the feed on mine I used one of the spares on the oil filter housing where they are blanked off with a hex head fitting. I intend to use the Lexus style mod you are doing for your oil feed to plumb in my oil pressure gauge. Keep up the good work. Quote Link to comment Share on other sites More sharing options...

Don't suppose you can remember who you used can you mate, I've found these ? Also have you got any tips on the resistor pack you made up to control the flow you mentioned earlier. I can't find any info on how to do this anywhere. Thanks Quote Link to comment Share on other sites More sharing options...
Supra_Scott Posted December 3, 2011 Share Posted December 3, 2011 Hi Jon, it was either the seller on the link above or a seller called nik-pro. Both come up when you type 'ultra sonic injector' into the eBay search function. As for the resistor pack, if i remember right the resistance has something to do with the time it takes for the ECU open/close signal to operate the injector. The NA injectors are high impedance and the MKIII turbo ones are low. The difference is around 10 Ohms when you test across the injector with a multimeter, but don't take my word for it. I ordered SH50 10R 5% Resistors, which are 50W, 5% tolerance 10Ohm resistors with a decent heat sink on them from Farnell @ £2.59 each ex VAT. We traced the injector loom back to behind the carbon can on the passenger side bulk head, and wired one resister to the feed for each injector. There may however be a better way of doing this. I had a stainless steel box made to house the resistors just to tidy things up. Hope this helps. PS. If you are using E-manage Blue you will need: Greddy 3bar sensor Greddy pressure sensor harness Greddy E-manage injector harness all availiable from Envy at around £150 when i bought mine.

Lacee Posted December 4, 2011 Share Posted December 4, 2011 great work mate. Like the color of the intake manifold But i will go with a standalone ECU Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 4, 2011 Share Posted December 4, 2011 Very very good idea re the flex pipe in the down pipe. I can flow test and clean the injectors, £11 each. I have got a suitable resistor pack, £25. Let me know if I can assist. good luck, very nice work indeed. Quote Link to comment Share on other sites More sharing options...
Noz Posted December 4, 2011 Share Posted December 4, 2011 You need a resistor pack OR in-line resistors. the 7mgte injectors are plug and play. Never noticed the difference with the tab before, thought I haven't put my injectors up again the clip... best for my to check that I think! If you need a link to the required resistor let me know. Resistor box is mega bucks, which in my opinion is money not required to be spent as an inline resistor will do the same thing, though not as tidy, about 10% of the cost.
