The project: LS/VTEC turbo is the ultimate goal. Started out as a straight LS turbo project, but things have gotten out of hand... now it consists of a built b18a block (81.5mm CP 9:1 pistons, Eagle rods, Endyn girdle, ITR oil cooler, fully balanced) and a b16 head w/ GSR cams. Valvetrain will probably be upgraded before it goes on the block.

At any rate, I'd like to be able to break the motor in safely before installing the turbo. I am worried that the air-fuel ratio won't be optimum running the P28 (most likely with a Hondata S200b) on a base map. I would rather not pay for tuning more than once - ideally when the turbo kit is installed - but I'm concerned that trying to break it in without tuning may damage the block (running too lean, too rich, timing off, etc.).

Now I am thinking I'll use the stock LS head, cams and ECU for break-in, then install the head and turbo later, along with the necessary OBD-1 conversion. Maybe in stages: install the b16 head, make sure it runs decently, no wiring problems, etc., then do the turbo after that.

Any advice?

 

Here's what got me thinking about this: http://www.importbuilders.com/breakin.html

 

can u reprogram the hondata yourself? meaning, did you pay for that option...? if soo i would buy the wideband and try to "semi tune it" yourself very conservative, really retarded and not that rich...but that's just me

No, I don't have the equipment or expertise to tune it myself unfortunately.

on the expertise part, is not that hard, i bet your tuner or some people here might give you a lil imput, remember, is not that you're going to tune it, is that you're going to make sure it gets enough fuel and ignition be fully retarted.

Now, on the equipment, well, that's ok.
IMHO, get it street tuned with your tuner, do whatever break in you believe in and then get it fully tuned.
Sorry to answer what you didn't wanted to hear, but do it the right way, believe me, it will be a lot worse if you blew it.
good luck

EDIT: some info i didn't say cuz i forgot, the tough part is this, you can't have a really rich mixture, since a rich mixture will pretty much wash away the oil on the cylinder walls and that will make you eat your walls a lot faster and it might overheat/blew up, and a really lean mixture will cause overheating and will either melt stuff or detonate.....
a wideband is a really good idea, check this link, the unit without the O2 sensor is like 190 http://www.plxdevices.com/M-200_productinfo.htm

if you decide to get it, you just have to make sure that the A/f ratio stays between lets say 12.5:1 to 14.9:1 to be safe, altough i think 12.5 is a tad rich, but i guess is ok.
