ok, i can't get a straight answer on this topic. some say it's ok, while others say it's a bad idea. the ones that said boost was ok with break in, told me to "take it easy and not floor it." i'm not planning on flooring it but, the method i'm using is (if you have a better procedure, please inform me) the old one's method. it is as follows:

"use 0-30, or 5-30, or 10-30 motor oil and a honda filter. do not use synthetic motor oil for break in...start it up and keep the engine at 2500-3000rpm for about 20 minutes. make sure there are no leaks, or mechanical problems. the only idling will be for setting the timing.

0-200 miles. try to keep the highest rpm under 3000 rpm. every 15-20 miles, zing the engine to 4500 rpm in first and occasionally in second gear.

200-400 miles. try to keep the revs limited to 3500 rpm. raise the zing rpm to 5500 with the same frequency as above.

400-600 miles. go to 4000 rpm for driving limit. raise the zing to 6000-6500 rpm and include third gear pulls. same frequency.

600-800 miles. 4500 rpm driving limit. zing it to 7000+ rpm and include partial fourth gear pulls.

800-1000 miles. 5000 rpm limit with zing to 7500+ with some pulls all the way through fourth and partial fifth gear pulls.

you don't have to scream the engine religiously at the prescribed intervals. if you don't have the space to run the engine up in the selected gears, don't do it. just know that you can, and if the opportunithy comes around, lay into it. don't over do the procedure.

1000 mile oil change is recommended. do a compression check and reset the valves."

that is what i'm referring to when i say the zings that are part of the procedure that WILL build up boost when breaking it in.

couple of questions though: what are the consequences of boosting during the break in procedure? what do i do with the oil return nozzle on the oil pan if i take off the turbo manifold?

and one last thing, it was pointed out to me that the break in with boost wouldn't be a problem because the same situation applies to a turbocharged eclipse with a rebuilt engine.

sorry for the long post. i would appreciate some insight and clarification on this issue because spending another $5000+ on another rebuild wouldn't be very fun. thanks in adv

 

I had the same issue arise with the tuner I am speraking too and the shop which is going to do my build up and his suggestion was you do want to break in the car with boost so that the rings adapt to the power they are going to expect to see but not as you said blazing through every street light or highway but just give the engine the hint of it that it's there. I'll take there word for the fact they have built numerous hondas and all are still running up to this day without a problem and running hard. Hope that helps.

You shoudl use a 30w Non-Detergent, Non-Synthetic oil for break in. Break in should be 500-1000 miles. If you happen to not follow the break in procedure, you are now prone to the rings not setting in correctly.

 

My experience from breaking an engine in w/ boost...

Dont.

drive like a san human being, law abiding speed limit fool... once you hit 1000 miles you can start getting on it. Dont get crazy becuase all the parts you have that are new havn't settled in yet... expanding and contracting over and over... once they are settled then you can boost...

if you dont like your car, then by all means beat the hell out of it... but like most of us, cash deficient peeps... you have to do it right the first time.

 

thnx for everyone's help. for gsrwboost: since you broke in your engine with the turbo installed, have you or are you experiencing any problems with your engine now?

 

I'm breaking my car in right now. I have the turbo on but I haven't revved past 4000 yet. I have 172 miles on it right now. I was told not to boost at all until at least 500 miles. Even then I would take it easy. I'm also breaking mine in with stock injectors because I was told it is very bad to run rich during break in as the rings would never set.

 

this poses another question. is it ok that i break in my engine with a set of 720cc injectors and a hondata 2b (with the base maps that is)?

and how do i plug up the nozzle for the oil return line if i do break the engine in with the factory manifold?

Break it in with everything attached.

30w non-detergent oil (NO SYNTHETIC)

0-200 miles, keep revs under 4k & 0PSI or less (change oil at 200)

201-500 miles, keep revs under 6k & 1PSI or less (change oil at 500)

500-1000 miles, keep revs under 8k & 2-3PSI or less (change oil at 1000)

Then change oil at 1500-2000 intervals. (check oil color for darkness and metal shavings)

With the frequency you mentioned before. Drive like a normal person (average soccer mom), and check everything every day (oil levels, coolant, plugs, etc...)

You want to break it in with a bit of boost so the rings get used to being pushed outwards.

 

what do you mean by "everything attached?" you mean the turbo system, 720cc injectors?

i appreciate everyone's advice on this matter but, has anyone run into problems with boost during break in and has anyone actually had the engine torn down after break in (for whatever reason) to see firsthand if boost caused any damage during break in, especially using the old one's method?

thnx again

 

i say dirve it 1000mile nicly. then slap ont the turbo and turn the boost up one psi every 150 miles. that what im doing

 

no engien related problems.. car runs fine....

only problem is the IAC, not related to any mods... has gone bad...

 

gsrwboost: how many miles do you have on your motor now? and if anyone knows, how can i plug up the oil return nozzle on the oil pan?

i just put a longer hose on mine than the the one i used for the turbo setup. then i just bent in in half and held it together with zip ties. no leaks at all.

 

Just wanted to see if there's any more opinions on the subject....cause my built GSR motor should be done by this week and I need to know if I should leave my car @ the shop a little longer to get the turbo kit put in or just wait until after I've broken it in.

 

you can buy metal caps for most types of threads.
