5T4R7ET N/A Posted December 12, 2011 Share Posted December 12, 2011 that is over kill, i have heard some starlet have idle problem when they have very large injectors. for 1.4 on a td04 i think you only would need no bigger than 440's and that would go up to 1.6 bar as well if you like.

string Posted December 12, 2011 Share Posted December 12, 2011 460s can support 300 plus. most people go for 460 with td04 at 1.4/.5 Quote Link to post Share on other sites

Stu Posted December 13, 2011 Share Posted December 13, 2011 that is over kill, i have heard some starlet have idle problem when they have very large injectors.It's more with the tune than anything. I have run rx7 550's in the past (which are hose pipes essentially) and have had no problems with idle. Sure if the injectors were in the inlet rather than in the head you might have a problem.440cc mitsi vr4 injectors are good, they have a very good spray pattern and mist well.

As I want the best I can get out the td04 and does anyone want to buy some sard550cc injectors then new except when I tried to run it with them in until I changed them Quote Link to post Share on other sites

lukeEP82 Posted March 14, 2012 Share Posted March 14, 2012 I was running stocks at 1.3 bar no issues, can't remember what duty they were at thoIf you were running stock injectors were you using up rated fuel pump and fuel reg. Quote Link to post Share on other sites
_shaun_ Posted March 14, 2012 Share Posted March 14, 2012 mines maped to 1.3bar td04 stock injectors uprated fuelpump stock reg Quote Link to post Share on other sites
DevonGT Posted March 16, 2012 Share Posted March 16, 2012 Get 440cc or 460cc at that boost, don't think about running stock the duty cycle will be way too high. Quote Link to post Share on other sites
turboloon Posted April 26, 2012 Share Posted April 26, 2012 as above i ran stock at a bar ,i'm now going forged and running 460's.. Quote Link to post Share on other sites
Stu Posted April 28, 2012 Share Posted April 28, 2012 and does anyone want to buy some sard550cc injectors then new except when I tried to run it with them in until I changed them If they're aftermarket Sard's then the spray pattern should be pretty good - its only the rx7 ones that people complain about but I've never had any issues with them. As long as your running a half decent ecu the Sard550's should be fine. Quote Link to post Share on other sites
