is 10lbs reliable?, garrett T3bb Options

[Kerr1]

ok im wrkin on a turbo kit 4 my freshly rebuilt 5sfe. heres a list of everything done to the motor:

bored .040 w/ topline pistons
arp head studs
soon to have arp rod bolts
cometic metal head gasket
everythin else if brand new but still stock..
new motor now has around 1000 miles on it

ive always heard a motor w/ arp head studs and rod bolts combined w/ a good head gasket can handle a lil more power and i was wondering since burien kits run a reliable 7lbs do u think w/ the right setup and proper tuning a 5sfe could be daily driven on 10lbs....

ne advice as appreciated thanx.

i was just thinkin that since a stock motor is "supposed" to handle 7lbs...i asumed w/ the few minor parts that r supposed to make ur motor a lot stronger i could run 10lbs fairly reliable......the kit is not going on my car until i have all the parts to tune it the right way...

Thats kind of what your not understanding. Mechanical strength is only part of the equation. Fuel and timing control is what really decides how much boost you can safely run. Plenty of people have blown their motors in the past on 7psi of boost, because they failed to upgrade their injectors or make any attempt to visit a dyno and tune their car.

The weak link in your case is the safc. Its a really crude way to try to tune for bigger injectors. If you want the car to last, you should look into something like an emanage, map2ecu, etc... that allows for direct fuel and timing control, and is not just fooling the stock air sensor like the safc does.

Don't take any examples from the burien kit. They sold only one of those, and didn't offer any form of tuning.
