Default Air or Fuel???

I'm upgrading as I can afford it, and would like some input on what people think. Which should I go with first..Injectors or Turbo upgade. I eventully plan on doing both, but just wondering which plp think should be first?

do you have head studs? if you dont i would get studs 1st! if you do have have studs i would say turbo first so when you do injectors you will be flowing enough to cool them off just my thoughts thats what im doing i have everthing ready for injectors next as soon as money is right

How hard are the headstuds to do on these engines? Would it be a day job or would I have to cut out a whole weekend for it? I've done them once on an old Supra and it was a PITA

i would say a less then a full day job if you did pulling them one at a time not having to change the hg

the way i see it help prevent a very known problem before it happens if i woulda known what i know now i woulda done it when i first deleted jmo. it didnt say turbo when i posted earlier cause i read your sig! if you dont mind me asking why did you go with the 62?

seen this on another forum and i highly agree (If you do not mod in the proper order, preventative first, then power, you will have to learn the saying "You have to Pay to Play".)

Well, coorsman, as you're saying about the preventive maintenance and upgrades; I figure, once i go in to change the headstuds, I'm probably not going back in for a long while. So I'll most likely change the HG for good measure.

well if your going that way i wouldnt go back to a factory gasket and i would o ring with vulcan hg make sure your surfaces are flat and do it right the first time ----and sluggo i didnt realize it was a compound setup i would def stud it i bet the drive presures are going to be crazy

I agree with the studs next better to change now then when your broke down. Then I would go turbo. The larger turbo with light quick with stock injectors top end will suffer but your going to need to do the CP3 when you do the injectors and if you do them before the turbo your just going to smoke out 3 city blocks send your egt's threw the roof and are not going to see much more hp.

I'm getting the second turbo put on friday, I'll take it easy till I get the studs in. Hopefully in a couple of months I'll have enough $$$ to go to Industrail Injection and have some injectors put in.. The core charge is so high, I'm thinking I can save some $$ by going to them and having them install them. Salt Lake is only about 270 miles from where I live, If I feel really rich I might have em put on a 33% over CP3
