4age stage camshafts Options

[20v_celica]

ok so i wanna buy camshafts for my 20v bt found some but heres wat i need to kno... ive been told if i go stage2 or higher i have to get new valve springs and everything else, but i have also been told the 4age blacktop was originally designed to be boosted like the 4agze, but due to japans economic situation at the time they upped the compression and left it a n/a... could nebody reassure me of the strength of the 4age head??? or do i really have to redo the whole valvetrain if i want stage2 cams??? anybody help!!!

Which camshafts are you getting? The only ones I can even think of are toda Camshafts. There was a few sets that didn't require you to get valve spring sets but there was 1-2 of them that did, but those were high durations. I don't think you want to make your motor such high duration unless your going for some seriouse Horsepower and high revving. I think if there too high your rpms stick around 2-3000 rpms, and you prob don't want that unless in a daily driver. By the way there so expensive, last time i checked they were around $600-1000 for 1 camshaft.

haha yea i kno well crower makes some and toda makes some... yes they are very expensive a set of two is like $1200 at the least... i kno stage 3's and up will set ur idle at about 3grand... my idle is already at 1100 so i figure some stage 2's will not be so bad, gain horse power without bein too annoyed at the idle and still save a lil bit of gas haha... but if u dont kno about the stages can u at least give me some help on which ones dont need valve springs or how hard it is to install valve springs... i heard it has to go to a machine shope to be remachined if u even wanna adjust them so changing them out must be expensive
