so i'm ready to start my 93 upgrades and I have some questions>I have a set of gt40 heads off a lighting ,all machine work has been done.I have a f303 cam 1.6 rollers a non egr cobra knock off intake,70mm tb,70 maf,shorty headers 410 rear and t5..I don't think i'm going to use the intake because of no egr and also going to have to use spacer.soo that being said,I was thinking of getting typhoon or track heat and possibly going down to an e cam and maybe spring upgrades on heads especially if I use the f cam...would that be wise to change springs even if I downsize cam to keep in rpm range of track heat or will the f cam and the typhoon be better.I know about the extra work needed with the typhoon cleanup for proper flow.should I use the non egr cobra intake and get the egr trick sensor, should i step up on injector size,just kinda stuck right now because I have all these parts but can't commit?The car is on the street and is stock except for bolt ons,gears ect... any help will be appreciated!
