88351wtsi Posted June 25, 2015 Report Share Posted June 25, 2015 Been installing a MS2 and cannot make boost. Gets to --0.02 and that is it. Checked plumbing all fine. Could secondary injector, fuel pressure, tune or something else prevent this? I know it's vague just losing my mind here. Link to comment Share on other sites More sharing options...

88351wtsi Posted June 30, 2015 Author Report Share Posted June 30, 2015 Headed out for PF Thursday afternoon. I have checked wastegate, even unhooked actuator and tied it closed. Can hear and see it turn, feel the air, and pressure in soft pipe leaving the compressor side but never gets above 0.0 Stumbles like crazy. Had a shop smoke test for leaks all ok on piping and intercooler. Link to comment Share on other sites More sharing options...
88351wtsi Posted June 30, 2015 Author Report Share Posted June 30, 2015 So far here is what all I have done, Rebuilt transmission and Megasquirt, Walbro 255, SPA fpr, New pair of matched 950cc injectors from FIP, upgrade from stock 600/930. 3" downpipe and full 3" exhaust with single chamber race muffler. 3-in-1 glowshift boost/temp/pressure gauge. Innovate Plx wideband. Don't think I've left anything out that would effect my issues. Link to comment Share on other sites More sharing options...
Project87 Posted June 30, 2015 Report Share Posted June 30, 2015 Try adjusting FPR. At least 40 psi. Link to comment Share on other sites More sharing options...
88351wtsi Posted July 1, 2015 Author Report Share Posted July 1, 2015 Fpr was at 65 when hooked up gauge now at 48 Link to comment Share on other sites More sharing options...
88351wtsi Posted July 1, 2015 Author Report Share Posted July 1, 2015 Can feel air from pipe going into throttle body but put hand over end and no pressure if that makes sense. Blow like crazy bland can feel it blow more when brake torquing but will not blow pressure just volume Link to comment Share on other sites More sharing options...
questtuner82 Posted July 1, 2015 Report Share Posted July 1, 2015 Sounds like the wastegate is not sealing. Just because the wastegate arm moves doesnt mean the wastegate flapper is sealing. Maybe its broken or carbon buildup is not letting it seat and seal Link to comment Share on other sites More sharing options...
88351wtsi Posted July 1, 2015 Author Report Share Posted July 1, 2015 Sounds like time for a rebuild...... Which means upgrade. Maybe go with a td05h 20g. Link to comment Share on other sites More sharing options...

scott87star Posted July 2, 2015 Report Share Posted July 2, 2015 05H is too small for these motors, 06 or 06H. Link to comment Share on other sites More sharing options...
