suprattgaz Posted August 3, 2008 Share Posted August 3, 2008 I just need to check that I am not hurting my new turbos!!! I think this is a fairly unique set-up so can't find anything on here for it. Something isn't running quite right, but just need to ask the question: I have UK hybrids fitted to my Jspec. Now I have not altered the injectors (still 440) or ECU (still std). Running at 1 - 1.1 bar will the fuelling be handled correctly by the std jap kit? I have some UK injectors and am looking at getting an emanage ultimate off Nic in the near future, but want to know if it is safe to run as it is without these on it yet?

Tricky-Ricky Posted August 3, 2008 Share Posted August 3, 2008 I already had an emanage when i fitted these, but i only ever removed fuel, but then i ran them in TTC, so there could be a potential weak spot as the second turbo comes in in sequential mode, so its probably a case of getting yourself an EMU and wideband asap, what is the running problem? slight miss around 4,000RPM by any chance?

Nothing to do with missing - it seems to be getting a weird loss of boost once it warms up. I'm wondering if the fuelling is wrong, creating a lot of heat and hence loss of boost due to less dense air??? I'm sure the engine bay was never as warm as it is at the mo (no gauges fitted at present so can't give figures). It makes a funny sucking whistle nosie after 5 mins or so of running, and drops boost to about 0.85 bar? Checked BOV, not that. Left it over night to cool, took it out today, ran fine, 1.1 bar for 5 - 10 mins, then slowly dropped to 0.8 after a few more runs and that noise came back again (noise goes hand in hand with loss of performance). Turbo 1 oil feed has a very small leak I hven't got round to fixing yet, that couldn't cause a problem would it (it is weaping, not actually dripping so much it is going on the floor)? I never booted it until this past couple of weeks as i was worried about easing them in, so this may well have been there from day one.

Nic Posted August 3, 2008 Share Posted August 3, 2008 It's impossible to say without an AFR readings, the 440cc injectors are okay with stock J-spec turbos at BPU levels, but with hybrid turbos you're probably pushing them close to their limit.

BUt the emanage ultimate I am getting off you will help with this won't it? Along with the UK injectors? Quote Link to comment Share on other sites More sharing options...
DaveSupTT Posted August 4, 2008 Share Posted August 4, 2008 (edited) Bump, im interested in this. I am just wondering if this could be part of the reason why my engine is the way it is. I too am running bpu with hybrids and as far as im aware i have stock injectors. I am at the process of starting a rebuild, and I may have a cracked piston head. Plus other lurking issues!

suprattgaz Posted August 4, 2008 Author Share Posted August 4, 2008 What is a emanage ultimate. Whats it do/replace and how much do they cost? Piggy back ECU. All in £490 off Nic (sensors, hannesses etc.) Then you have to map it (£300 ish) Quote Link to comment Share on other sites More sharing options...

heckler Posted August 4, 2008 Share Posted August 4, 2008 I ran my hybrids with UK 550's with no probs - but i belive some run 650's. Of which both will require some sort of control Quote Link to comment Share on other sites More sharing options...

heckler Posted August 4, 2008 Share Posted August 4, 2008 Is a piggy back ecu the only option? or stand alone with 550's and no emanage, it will over fuel like buggary Quote Link to comment Share on other sites More sharing options...
bolarbag Posted August 4, 2008 Share Posted August 4, 2008 What power are you making? If its over 400bhp your injectors will be close to the max duty cycle at wot, I'd lay off until you get the 550's, 650's would be even better Quote Link to comment Share on other sites More sharing options...
DaveSupTT Posted August 4, 2008 Share Posted August 4, 2008 Well at the moment I am not to sure what power im making! As at the moment I am just starting an engine rebuild I have loads off issues, which I was wondering if this could be one of the reasons for some of my problems. Link to my issues etc http://www.mkivsupra.net/vbb/showthread.php?t=158179 All I know is that I am running BPU with Hybrids. Quote Link to comment Share on other sites More sharing options...
Nic Posted August 4, 2008 Share Posted August 4, 2008 What is a emanage ultimate. Whats it do/replace and how much do they cost? If you don't plan on going single, then I'd replace with a set of Power Enterprise 550cc injectors, these are a straight swap into the stock rail, they are also high impedance so no need for a resistor pack. If you may go single in future then PE 680cc injectors. Quote Link to comment Share on other sites More sharing options...
DaveSupTT Posted August 4, 2008 Share Posted August 4, 2008 Hi Nic. Im definetly not going single. How much are we talking for the Power Enterprise 550cc injectors? Quote Link to comment Share on other sites More sharing options...

DaveSupTT Posted August 5, 2008 Share Posted August 5, 2008 Bump for Nic Also is there anything else I will require. On my car at the moment I also have a Aeromotive fuel pressure regulator but im not convinced this is set up correctly. Any advise would be appreciated.

Dash Rendar Posted August 5, 2008 Share Posted August 5, 2008 Dave, it was 315RWHP, which is a little shy of 400FWHP. (That's before your engine troubles started, that is). Quote Link to comment Share on other sites More sharing options...
