ok thanks for the advise guys, ill keep everybody updated on the build.

i wasnt talking about keeping my n/t ecu, i was talking about switching to the turbo ecu, would it be wise, and necessary, im starting to think that a 16 g turbo would be better, at what rpm does a 16 g start to spool? im planing on switching to a welbro but if i keep my n/t ecu, would it hurt...

ok so would i need to put a knock sensor in, because if the turbo ecu will just hook right up to the n/t wiring harness then that means i should have the connection in my engine bay for a knock sensor, if im wrong correct me, but would it be wise to go ahead and put a knock sensor in?

i was planing on changing to a turbo ecu, but wouldnt i have to reprogram everything or would it just be unplug the nt ecu and plug in the turbo ecu and be good?

i picked up a GM mass air flow sensor, and i know a guy here in town that will tune my car, hes got all the programs. i was told also that when you switch over to the Gm mass air flow sensor that you have to get a box to hook up the pig tail from the GM sensor to the 1 g nt air sensor pig tail...

im not tring to rush turbo'ing my car, i've done more and more research on it since i got the thought in my head, im first getting a 255 pump, 450 to 550 injectors, im switching the ecu's out, cams and upgraded fuel rail, and FPR. what else should i change, i know im leaving some things out.

what would a "non ebay" turbo housing have on it?

this is the pics of the turbo, let me know what you guys think.

i took my turbo to the tuner shop here in town yesterday and they took a look at it, and they said it was in good shape, but the flange for the waste gate is a older tial 40mm 4 bolt, so im going to have to try and find a good waste gate that will fit my flange or cut mine off and weld an...

and thank you abaum565your advice cleared up alot of unanswered questions, that is what i thought a bov and waste gate were, i just wanted a second opinion, I am getting a welboro 255 and i beleave 550cc injectors. ill be posting pics of my turbo and manifold 2mrw after i get home from work...

i would actually much rather you just not try and help me at all thru this build to be completely honest with you, all im doing is tring to get advice, and honest help from people that has done this before, not self centered pricks like yourself.

i didn't get it from ebay, i got it thru i guy off of craigslist

i know what the main differences are between them, but correct me if im wrong, a bov releases all the that goes into the intake while shifting, and the waste gate controls how much pressure is put into the system?

im asking for your guys input and help on this, but if your just going to degrade me then go somewhere else to do to somebody else

and also whats the difference between a BOV and wastegate?
