I just finally finished my B20 swap running pretty crappy right now cause im guessing everything still needs to adjust. Im gonna do a tune up on her soon but I was wondering how many miles is considered breaking it in? before she can really be driven. Any advice you guys got would be great, thanks

1000miles my guess...

 

is it a newly rebuilt b20? if not, you don't need a break-in, just do the maintenance on it and figure out why it's running crappy

 

Are you using the right Ecu?

Check engine light?

 

im guessing it just needs a basic tune up its runnin kinda sluggish and as for the ecu a buddy of mine did a majority of the swap and I just "spectated" lol I was told to get a P75 off a teggy

 

P75 is for a 1.8L... congrats, you go the wrong ECU.

derp

 

It would run fine on the p75, might not get its max power but it will be fine to drive. All the b20 is is a bored out b18, the p75 would operate the motor fine.

 

indeed ^

 

I said I was told to put a P75 ECU in it when I get one, and theirs two other guys in here that say it'll run fine off a P75 so "congrats" for looking like an idiot. ha

 

p75, p28, p06, pr4 will all work. You still need to get it chipped and tuned though for it to run well and even stronger. http://xenocron.com/ they've got great customer service.

 

Thanks bro! I really appreciate it ill def look into that website you gave me!

 

If its a stock B20 (not rebuilt) it doesnt need to be broken in.

 

good looking out guys I think just to be safe ill give it about 500 miles or so it was sitting in my garage for about 4 months.

 

Nah your good to go bro. I had my B20 running on a P75 for 2 years before i got it chipped and tuned it ran fine.

 

Go to a tuning shop and get it tuned.

Sitting in a garage for a few months isn't going to make the engine run funny for any longer than a few minutes if at all.

 

aight cool just out of curiosity what did you chip your ecu with? I gotta make sure it doesnt shoot any codes or anything like that either cause I have to pass emissionss

 

ya know you could always just hit a junk yard and pull a 5 speed crv ecu that doesn't have awd. pretty sure they're under the dash. it'll take you about 10 mins to pull it if you have the right tools.

 

get it chipped to run a b20 map.

 

I Just chipped the P75, Then I switched to a P72 when I went b20 Vtec with a GSR head. good luck bro

 

the proper way to store an engine is to fill it up completely w/ oil and it will run EXACTLY like before it was pulled.if an engine is store improperly(lay'n around),or from japan(lay'n around in japan), it will need a 500 mile break-in. 1000 miles is kissing it's ***, no need for that.

 

good lookin out fellas!

 

really...the first 30 miles is the MOST CRUCIAL.
