Stock, upgraded stock, or ATP turbos ??

TopherSho · June 08, 2017, 03:23:36 PM

Maybe? I do not know the metrics of the turbos Vs stock, but they may be more efficient at the same turbine rpm and generate less heat, they may spool faster, they may be lighter (doubt that one)?

I'd talk to tuners who have experience with them specifically .. they re likely to know more.

Been meaning to reply to this for awhile...So busy I can hardly post anymore...I think there is benefit to upgrading the turbos even on a stock SHO...

I don't think the increased size of the wheels on the upgrades are big enough to cause adverse effects on spool..The stockers are so little they can actually spool too early if you want...I'd be willing to bet you could get full boost well before 3k on the bigger turbos.

Even the stock fuel system has plenty of fuel to spark above 4000 rpm so you will get more airflow at high RPM from the turbos which will get the HP up even without the extra torque down low...So you can have more power and not additional stress on the drivetrain or internals....Maybe even a couple hundred more RPM since the turbos won't be the choke point and that alone can be worth power.

I would upgrade if you have the money to spend.

IMHO after all I've seen and done I'd suggest the upgraded stockers. Why? Because the ATP's are overkill for this platform until somebody figures out how to keep the trans together.
On the upgraded turbos I made just under 500WHP on E85 which could also be done on race gas which is more than enough for the drivetrain without having long term negative affects. It also stops you from turning it up just a little more. We all know the stock block can't handle the ATP's for more than a few months on high boost. If you're building the motor and are prepared for semi-annual trans builds as a worse case scenario then the ATP's, if you want a fun daily then the upgraded stockers with the Tial WGA.

I know you have done a TON of work on this platform yourself and if you don't mind me picking your brain... at what hp/tq to the wheels would you consider max for a daily driver? I saw some post saying 500 hp / 500 tq is it... others saying 450 eitherway... at what point would you say is about it?

EDIT: Apparently I skimmed the part where you already said 500... nevermind!

One more thing about upgraded stockers, I send you new CHRA sections to install on your existing turbo "shells", no down time, no shipping turbos, no core charges. ATP you'll have to send in your turbos after ordering and wait 1-4 weeks for them to ship you the new turbos. That alone is a huge consideration.

I thought we had to send the stocker to you for the new CHRA? That is a BIG plus that you send out just the CHRA section for install... I was unaware of this.. I have not found anywhere online that will send out just the CHRA....even stock... thumbs up!! You maybe getting an order soon..

EcoPowerParts · June 09, 2017, 11:51:57 AM

Nope, new CHRA sent out now, makes it super easy. You get two CHRA and two Tial WGA ready to install.

thanks for talking to me on the phone yesterday and explaining all this. I'll probably go ahead and order them today.

My only concern is having thrown a rod is metal fragments having gotten into my stock turbos. As I recall your CHRA replaces the seals and components that I would need to be concerned about where oil inside my turbos could have been contaminated by metal particles / fragments whatever ??

I like the idea of your turbos but I want all of the turbos to be fresh / new with this new longblock install.

68_GT · June 13, 2017, 02:42:20 PM

is this all the CHRA is ?? basically replacing these internal sections ? I assume install is self explanatory or easy with the motor out ?

so this is what you get with the upgraded turbos.
here is the process

Looks straightforward.

To the OP I was wondering what caused the engine failure? At 130k and minimal mods, I was thinking the dreaded internal water pump. Also, how is the car running now with the new engine and turbos?

I'm looking at upgraded turbo's myself soon and thought this was a good resurrection thread since many of us are approaching 100k miles or more.

Its always good to discuss and reread thing from the past that got us here to today.

My question is. Just because you can. Doesnt mean you should.

Why not install the ATP total upgrade turbos. Run them at a Daily Driver known power rating so you dont break things. Isnt that better for the Turbo's and maybe some other components to be run conservatively but keep the car in the Low 12's so its a blast to drive. I know it costs more but why not?

I think its a question of budget/goals as well as car health. For much less you can do the EPP CHRA upgrade, and get the power you want for a DD. If you only want a mid 12s to low 12s car, you dont even need the turbo upgrade necessarily.

It's like in the mustang world where people nickle and dime themselves with bolt ons (CAI, longtubes, throttlebody, etc.) instead of just getting a supercharger or turbo kit to start. Or when people go boosted, but don't upgrade the fuel system at the same time, so they save some money and then during tuning, they have to stop before they get the most out of the blower/turbo because they run out of fuel.

It's all a matter of perspective and patience IMO.
