digs Posted February 1, 2013 Report Share Posted February 1, 2013 Hi, question on injectors for my 3sfte build, I have 3sge injectors (295cc I believe, green top) that I was going to fit, but on reading a lot of the 5sfte builds, they recommend supra n/a injectors (315cc). Can get some from the US used for not that much, but are they needed? Only planning low boost, will I max out the 3sge's pretty quickly ? 3sfe injectors are 200 cc injector info from here; http://www.club4ag.com/faq_and_tech_pages/Toyota_Injectors_Specs_Data_Denso.html Link to comment Share on other sites More sharing options...
Guest Posted February 1, 2013 Report Share Posted February 1, 2013 The 3SGE injectors will be fine on high boost (0.8bar), but you could also use a fuel pressure regulator to bump up the fuel pressure a little to run safer on higher boost. The main reason the US guys use the 315cc as oposed to 295cc is because they are more easily available. They didn't get the 3SGE engine. Link to comment Share on other sites More sharing options...
digs Posted February 1, 2013 Author Report Share Posted February 1, 2013 (edited) Cheers Jeff didn't realise they didn't get 3sge, once size fits all 5sfe then. That's cool, will go ahead with the 3sge injectors then. Have 4 days booked off in march, will be reporting back, two turbos now so have a back up On a slight tangent did read an interesting thread on a guy who put a older 3sge head on his older 5sfe and got it working. http://www.toymods.org.au/forums/tech-conversions/43868-tutorial-how-build-cheap-5s-ge-motor-5s-fe.html Edited February 1, 2013 by digs Link to comment Share on other sites More sharing options...
