Making a turbo list and checking it twice
Making a turbo list and checking it twice i know corny lol but im getting ready to do a budget turbo build on my trans am and am just looking for conformation on my list and possible suggestions
t76 on3 turbo
modular turbo hotside
ebay intercooler kit
probably bov and wastegate from modular
oil feed and drain with scavenge pump to oil fill
modular oil feed block
modular ps lines
modular alternator relocation
60lb seimen injectors
aeromotive 340 lph pump
colbalt 2 bar map
317 heads
ls9 head gaskets
arp head bolts
regap rings
ls2 timing chain
chain guide
aeromotive euro wideband
boost gauge
monster stage 3 clutch
tune by frost i live in va
10 psi most likely or 8 looking for 530-560rwhp i have tsp 228r in the car already .... dont plan on track use so im keeping the stock rear until i get funds again ...any help is greatly appreciated this is my first time boosting and just want to cover all my bases i dont plan on brfpr or anything like that i just plan on running stock lines and rails and im doing speed air density ...i also have a ls6 oil pump with .125 washer in relief spring .... thank you guys in advance

I would go with a walbro pump and a 12615136 2 bar map. Also, do ARP head STUDS not bolts. Other than that I think the list looks pretty good. Im assuming you have dual valve springs and a set of pushrods when u did the cam
a double roller timing set is also a nice piece of mind. The ls2 will work but better safe than sorry..

There are other affordable options out there for head studs other than ARP. You seem to have pretty modest goals so you don't need to strive for the strongest and most expensive studs.
Btw, if you're really worried about throwing out the extra $90, then a turbo build is not for you.

I've seen someone on this board make 677 whp through an unlocked 4L80e at 15 PSI with the on3. That puts it right on par with your numbers.
I would also say head studs and I would also recommend a better turbo. Even a turbonetics tc76 would be more reliable. You gotta remember that if that turbo blows during a WOT run your motors probably going with it.

What are you basing this on with regards to the TC76 being more reliable than the On3 76mm? The implication you've made is that there is a greater likelihood of the On3 turbo blowing up. I haven't heard of any trends that the On3's blow up and take out motors at WOT. Where's that coming from?
Again... just curious.

Interesting. I can't say I've come across any threads about a catastrophic turbo failure for On3 Turbos. Not saying that there is no such animal. Just that I don't think there's any statistical evidence that it happens more frequently than any other brand. That's all. Sounds like a wive's tale to me.
Did the blown up chinese turbo of which you speak take out the whole engine too?
Generally, my understanding is that when most turbo's fail, the owner notices that it doesn't make any boost, inspects, and finds considerable shaft play and the bearings would leak oil. I don't know of any street/strip cars that have had an On3 turbo go to catastrophic failure at WOT like you mentioned. If you know of any (or anyone else does), I'd be interested to hear about it, especially since I've got one on my car. No issues in 15k miles.

If you ever plan to remove the heads for whatever reason, the studs instantly pay for themselves.

That list looks complete, I would when you get the 317's clean up the exhaust ports and try to smooth them with some tootsie rolls. Just make sure you build around thepossiblity of wanting more power. That tends to happen
I would disagree, most companies have there products made in china and they make there way onto plenty of high horsepower cars. They are all made the same way. I would suggest taking apart the cheap turbos and inspect and measure everything to make sure it does not prematurly fail. As for the ON3 turbo, dont listen to the negative people, they are just mad they spent 1500$ instead of 500 and are making the same power. As for the turbo taking out the enigne, if that is the case then the people that run into that are fing stupid. You would be able to hear it.

I've seen all of 3 chinese turbo failures. 2 of them were back when the Chinese were first producing knockoffs, and the third was from oil starvation.
Not saying the cheaper turbos are more reliable. The name brand turbos obviously are capable of more power, especially with options like billet wheels and upgraded compressor housings. The problem is that so many people give them a bad reputation because they 'heard' they were bad.

Most of the stories about "Chinese Turbos" failing start out as spun journal bearings due to improper oiling... then someone latches onto that story and tells it to a friend and it changes from a failed bearing to "That turbo blew up"... that in turn perpetuates to the lore of "taking out engines". Again... not saying that they can't fail in that manner, but probably the same failure rate as a Garrett, Turbonetics, or Borg Warner (Catasrophic failure I'm talking about). And like mentioned before, if you see a cloud of smoke behind your turbo car... shut the engine down and check it out. "Chinese Turbos taking out engines" is more lore than not.
Sorry OP if this got off topic. I just don't like unfounded stories being perpetuated. You should be fine with an On3 Turbo in your build, especially at sub 1000rwhp levels.
Good luck!
