Ono Posted June 11, 2015 Report Share Posted June 11, 2015 It's time to purchase the injectors for my MPI....after many, many years......Is Trilogy the best place to get them? Anybody know where the best place to get them are, brand etc? Cost is not an issue. Thanks! Link to comment Share on other sites More sharing options...
NotStock88 Posted June 11, 2015 Report Share Posted June 11, 2015 I found the best price from an ebay seller. They are standard delphi injector size so they are going to be readily available. What size you thinking of going with? Link to comment Share on other sites More sharing options...
NotStock88 Posted June 11, 2015 Report Share Posted June 11, 2015 I work at a GM dealer. Get me what size you want and i will do a quick check for you if you want. Link to comment Share on other sites More sharing options...

NotStock88 Posted June 11, 2015 Report Share Posted June 11, 2015 Delphi require spacers and longer screws. He said for his MPI - not TB where you need the spacers and longer screws Link to comment Share on other sites More sharing options...

Ono Posted June 12, 2015 Author Report Share Posted June 12, 2015 Hmmmm, thanks for the responses guys. I was thinking 75 lb injectors......isn't that pretty much the status quo? Thanks! Link to comment Share on other sites More sharing options...
StarquestRescue Posted June 12, 2015 Report Share Posted June 12, 2015 I have been using http://www.fiveomotorsport.com/ Stay away from trilogy. He no longer sells Delphi's. Link to comment Share on other sites More sharing options...
scott87star Posted June 12, 2015 Report Share Posted June 12, 2015 Injector Dynamics, its a no brainer. They flow test everything and match them in sets. Link to comment Share on other sites More sharing options...
ucw458 Posted June 12, 2015 Report Share Posted June 12, 2015 I got mine from fuel injector clinic. Flow tested and matched set. Cost around $400 but worth it. Don't cheap out on injectors. Cheap crap can lead to engine failure. Stay away from smart fire on ebay. When ordering you want a domestic style injector with o-rings on both ends.

Ono Posted June 12, 2015 Author Report Share Posted June 12, 2015 Outstanding, all good info! So........75 pounders would be good? Bigger? Smaller? Link to comment Share on other sites More sharing options...
TexasQuest Posted June 13, 2015 Report Share Posted June 13, 2015 Depending on your power goals. Always easier to dial back larger injectors than to push smaller ones past their limits. Link to comment Share on other sites More sharing options...
ucw458 Posted June 13, 2015 Report Share Posted June 13, 2015 75 lb will get you to around 350 hp on pump gas before you run out of injector. Remember you want more injector than your HP goal. Calculate your HP goal fuel needs then add 20%. Then make sure your pump can push what the injectors can flow. Link to comment Share on other sites More sharing options...

Ono Posted June 14, 2015 Author Report Share Posted June 14, 2015 Again, excellent info guys, I appreciate it. I really don't have a HP goal, MPI was more to wake the car up and reliability. The motor's been rebuilt (along with the tranny and dang near everything else in the car) with Hyper U pistons..in other words, it wasn't designed to be a HP monster and will never be driven hard or really taxed other than highway speeds plus a little extra. I'll check out the links provided. Thanks fellas! Link to comment Share on other sites More sharing options...
