Ok Iv been building a GSR motor. Here is the run down
Eagle H beam rods
CP Pistons 9.0-1 cr @ 81.5mm
blockguard
full ferrah valve train from ti retainers to ss valves.
Every internal nut & bolt is ARP
RC 440 AEM cam geras
etc
etc.....

Im planning on going boost but, my question is should I break it in before I go boost? or break it in with boost?
Is their a posative or negative to doing it either way?

Any other personal thoughts on break in will be taken into consideration. Im just trying to get some opinions.

 

i would break in atleast 500 miles before you boost it.. but thats my opinion..i dont know turbo to much,will the car run with the low comprision.

 

i think either or will be fine...while ur breakin it in u prolly wont hit full boost anyways....i plan to have mine installed with turbo and just put 9psi on it durin the break in..which it wont see over 4000rpms for a while so it should be fine...

 

Im kind of leaning towards not boosting it untill it is broke in. Wich means getting it tuned two times. Iv got soooo much money tied up in this damn thing I double check everything just to make sure its right.

 

Simple run down.
1. Cycle the motor to ensure oil pressure
2. Start the motor and monitor oil pressure / coolant temp
3. Monitor true air/fuel ratios to ensure the fresh rings/pistons are not being washed out by fuel. At this time setting ignition timing is a good idea.
4. Top off coolant / let system cycle with radiator cap off etc.
5. After everything appears to be ok, no leaks, motor is at operating temp & thermostat has cycled 2-3 times, shut down the motor.
6. Change the oil & filter (if you want to).
7. Drive the vehicle and watch for proper air fuel ratio mixtures again...
8. Keep the rpms away from one single load level for a long period of time.
9. Watch the motor using a vacuum gauge to monitor the amount of vacuum it is pulling (you can tell when the rings are seating).
10. Put the vehicle through a couple of heat cycles and simply change the oil.
11. Tune the car at full load after everything checks out.

I can go on and on..
Some builders re-tq the cylinder head & check valve lash after 1000 miles etc.

Everyone will have their own 2 cents on this subject.
Good Luck.

 

I was waiting for your response Do you think I should get it tuned before I break it in if Im not boosted or could you just chip me an ecu for my set up (non boost) & I break in & watch my guages? Then once Im satisfied that all is well & broke in Ill go boost. She will be spending some time with you sooner or later.

 

It is honestly up to you. Some people pay to have their motors broken in on a dyno. Some people trailer there cars out to tuners for 1st start up. Some people pay tuners to come out to their location and start up the car etc...

One thing you could do is start the car on a stock set of injectors & a stock ecu. This would allow for less of a chance of your rings being washed out.

Starting a new build up on a basemap is hit or miss. I would not recommend it unless you have a wideband oxyen sensor installed in the car.

 

can u explain washed out...im about to build my motor etc...and i dont want this to happen...ty

 

too much fuel in the cylinder & it seeps past rings & removes the oil from the wall (washed out) & causes premature wear
Ok thx alot

 

Install the turbo kit and everything you plan on running. If you are confident that you have everything setup correctly and that you won't have any issues, pay for your tuner to come out to you (or you tune the car with a wideband). I have built over 15 different engine setups with this with no issues. My same turbo motor has been in my car since 2000 with this method. Then I concur with the following modifications below:
