Boost is the last thing you can play with. 10psi and your safe, bump it up and play at your own risk.

You MIGHT be able to run all the bolt-ons while keeping the boost at the stock level of 10psi. You CAN'T crank the boost up and keep a/f ratios safe with the stock ECU. Some cars, even stock ran 11-12 psi on the first turbo, while still only have 9-10 on the second. Boost also normal tapers off heading towards redline, on a stock car it goes down to ~7psi. Fuel cut near redline is around 10.5psi.

 

Okay, thanks again turbojeff.

I think what I'll do then, when or if I get the car running, as a start is just put the 3 inch downpipe then 3 or 2 1/2" pipe straight to the muffler until I can get a stock or performance cat. Then put on a manual boost controller, boost gage, turbo timer, and run it at stock settings 9-10psi, until I can figure out what I am going to do bigger injectors, fuel pump, upgrade the ecu, ect.

What do you guys think, will it work w/o ruining the engine or am I just foolin myself.

 

Turbo timer = waste of time and $$ for FDs
You don't need bigger injectors or fuel pump for a while, stock is good for over 300hp at the wheels IIRC.

You probably will have a hard time controlling boost without a cat, like as in you can't control. The only thing that might save you there is leaving the stock IC and intake. Otherwise you'll need to port the wastegate.

 

I'm just courious why would you say the turbo timer is a waste of money. I mean it should still be good for extending the life of the turbos, I know the turbos aren't new but still I imagine it could be of some benefit.

LOL, it sounds like I wont be able to get away from the cat, then I think I'll pick one up from the classified section of this forum hopefully just to get me started. Because I don't want to regret not listening to you guys about that.

So what kind of mods would I need, to handle a testpipe install if I later decide to do so?? just an ecu upgrade for the fuel ratio...

 

The TT argument is long. But it basically boils down to if you can refrain from pulling into your driveway at 7500rpms in 1st gear (drive without boost for the last mile or two before shutting down) then you do a better job cooling down the turbos then by keeping the car running with no airflow over the radiator/oil coolers.
