how many psi, and do you have/have you had any problems?

6-7 psi, stock injectors/internals. no problems other than my constant paranoia.

in about 1.5 months, 15 psi on 400cc and a vt block w00t!

8psi on a t3/t4e 50 trim

stock internals/injectors/93 octane pump with other mods-

-nitrous cams
-cam gears
-55mm TB
-2.5" turbo back
-UDP
-and 38,000miles on a CENTERFORCE DF CLUTCH....holds like a mother

-no problems other than with the turbo itself, the engine has been 100% rock solid.

countless of us. I am affraid that i might have a blown head gasket, but thats after a year and 30k miles. Also, i think it was caused by the bodyshop making some runs , when i got the car back the boost controler had popped off and the car was low on coolant over heating.

a blown head gasket can heppen regardless of the turbo though.

7psi for about 9 months. Talonized has been pushing 10psi on a star kit for about 2 years.

6psi/310cc Injectors/SAFC -- 12 months, 13,000 Turbo miles no problems.

I can't even believe that this is being asked. Anyway, 2 engines later, I guess stock internals for about 12 months now ??? 6-7 intercooled psi.

5psi, non-intercooled, stock internals/injectors. No problems, except for, like mentioned above, constant paranoia. Headgasket was replaced before going turbo. Got 117K on the car, been boosting for about 3k. If you keep up the maitnence, watch the CEL's, and watch the fuel pressure, there shouldn't be any problems.

1 year 10,000 miles on 8psi intercooled. No problems at all and I still have the Craptech FPR. ( I check my fuel pressure every few days, can't wait till I finally get my electric gauge, and then later an SFMU )

Thats the problem with you guys... You guys live in the middle of everything, dont put many miles on your car. Then theres someone like me, who has to drive 10-15 miles to and back anywhere I go, lol bastards. :)

stock internals 7-8 psi 65K miles. No problems other than blown spark plug gasket (1). Don't get too greedy and you should be fine.

10 psi daily 415 injectors safc 13,000 miles turboed

I boosted 8psi on stock internals for about 3 months and then a ring gave out so I went and did the full rebuild.

7 psi on stock rs

nice post man, i just wanted to give u props on that. someone will read this and be helped, couldnt have said it better :-) watch the fp and cel's and shouldnt have any probs with stage 1. :thumbsup

1 1/2 years of boostin at around 6-8psi intercooled. Blew one motor on dyno from overboosting and have been on current stock motor for for then a year. Used to have overheating problems and now car just smells bad and runs mad rich. Corbin is still the man boostin at 6psi on stock internals for at least 3 years now.

As long as you can adjust fuel pressure properly with an understanding of what the engine is going through during the transition from vacuum up to full boost.. you'll last. I was HRC stage 2 @ 10psi for 3 years (37,000 mi.) before I decided to change out the guts.






420a and ej20... both with boost

6psi for 1 weeks every since then 9psi i would say over one year, then 12psi for a few months.. soon i will have my engine in and in a few months it will be 15psi on a built motor.

i am at 6-8 psi intercooled, 67,000 miles, weekends only, since May with no problems... not a long time, but she runs like a dream and hope to stay that way!

6 psi non-intercooled (for a few more months at least}() 69k on the motor and only 3k on the turbo even though I installed it January and hit 66k during tuning. I guess I don't drive much:wary. Anyway I'll only be boosting 6psi intercooled until the rebuild. Oh yeah, and no problems here.

i lasted about 9 months at 8-9psi daily. The abrupt halt was caused by attempting to tune my 440's/SAFC/3:1 fuel system, and getting greedy with the fuel. 250 miles on a full tank of gas made me yank a bunch out in an attempt to retain my gas milage. Dumb, but i learned my lesson.

Ran 5 psi for a few months, then up to 8 psi, with no probs at all. Then got a bit boost hungry and cracked some piston ring lands at around 11.5-12 psi, with great tuning and plenty of fuel..Dont just say if you have enough fuel you will be fine..the stock cast pistons can only take so much power...You guys are pushin it at 10+ psi :o

I have been for the last 3 years. I want to rebuild, but not enough $$$

8psi for about 3 years.. no problems whatsoever.. now breaking her in for 15psi :)

I feel so much better........

I feel alot better myself to read about so many of you guys boosting on stock internals. I myself am in the works of installing a star stage 2. I will keep the boost low, and baby my car even more:thumbsup

started off with 5 psi
then 7-8 psi intercooled

for like 1.5 years
