Say you are building a d16 for boost (new pistons/rods, bearings, arp head studs, stock head) , and you have a turbo setup only partially put together, with basic fuel management, fmu and a 255lph fuel pump, and no intercooler. Do you;

a. Wait until you have all the turbo goods, intercooler, hondata, injectors, etc. and install it all together with the freshly built engine.

b. Install built engine and basic turbo setup, running mild boost for break-in and eventually upgrade turbo components.

c. Install built engine, break-in without any turbo, wait until complete turbo setup is on hand to install it.

Just would like any thoughts on the subject, and any detailed pros/cons you might consider with each option. Thanks guys.

 

I would personally break it in first, without boosting at all, and then run mild boost until your setup is complete.

 

patience is the key in a project dude !

 

install complete setup built motor and all and take it to the track after only letting it idle for 30min and changing the oil once.

Trust me, I do realize that. This project has been ongoing for a long time.

I just want to know if there is any reason one option is better than the others, and what the reason is.

 

I'm doing exactly what you are.

We're putting the engine in and getting all the issues worked out if there are any before we even touch the boost. One thing at a time.. this project has about 5 months budgetted, we have most of the parts in the basement now.

Tis what I'm gonna do - well, break it in first at least

See, now that is what I was thinking. Just wondering if it would be detrimental to the engine if it were broken in with boost, even mild.

 

I got my last car running and drove it around normal (everything hooked up just didnt get on it at all) for a few hours and made sure everything was coo then I just drove it for about 500 miles not getting on it hardly ever but I had no trouble with ring seating or anything ran fine. Id say as long as you are easy on it and dont boost it alot if any (just keep your foot out of it) you will be fine.

 

Sometimes its almost harder to do it half-***. Having proper fuel management to be able to fully tune it for driveability is worth so much and often over looked.

Patience

That's a good point. But do I postpone the engine install as well, or have it nicely broken in for the completed turbo setup.

 

It won't hurt anything at all to run without boost. We're going to run the stock ECU with a different intake manifold. Power will be down a bit (9:1 SRP pistons) but it won't hurt anything, and it will make sure the rings and bearings have seated before we hit them with boost.

 

C.

Perhaps the most important thing I've learned in life...

Patientce is the key to success.

I'll admit, I was leaning toward my third option, but always wondered if it would be better to boost for break-in, since it will be a built for boost engine.

Just looking for some re-assurance, and any opinions on the subject. Thanks to everyone that has contributed here so far.

 

I am also going with option C with my setup. I look at it as an easier way to work out the bugs in the car since there are less variables that can go wrong at one time.
Once the motor is broken in and running strong then the turbo parts can be installed, and if anything needs to be worked on then there are again less variables to be attrributed to the problem since you know the problem must lie in the turbo setup itself.

I see it as less headaches but thats me :shrugs:

....worst thing you can do to a new motor is let it idle. The absolute worst!

start it, and beat on it. It needs to see maximum stresses from the moment it warms up to properly break in.

There are a couple of schools of thought when it comes to break-in it seems, but they do both agree that idling is the worst thing to do to a fresh engine. Thanks for the input all.
