im gonna turbo my b20 in a crx very soon.. i was wondering, how can i do the turbo break in period if i dont want to drive it before its tuned? or how can i drive it untuned for the break in period.. idk what to do lol can anyone help?

 

run it on 0 boost...

 

You can disconnect the charge piping and run the stock injectors, or call ur tuner and get a base map, or ur tuner can break it in on the dyno. Good luck.

 

alright thanks, im new to turbo's and its a question not often addressed. most just run without a tune and i happen to like my motor

 

is the motor brand new 0 miles if so i did 2 heat cycles and made sure no leaks then went str8 to the dyno to tune if the motor is not new install the turbo kit turn on the car and check for leak if no leaks take it to the dyno

 

You can break it in on the dyno. If your engine has zero miles, if its a fresh build, run SAE30 oil through it for maybe a heat cycle or two then drain the oil and put in 10w40 oil.

 

no, the motor has around 50,000 on it but its pretty fresh. i was just referring to the turbo break in period, and how i would get it to my tuner and all that. thanks alot guys. oh, and i might be thread jacking myself but im runnin synthetic in it, would i run 10w40 synthetic after i install the turbo?

 

I have too many questions that I want to ask. I'm not really sure where to start. Is the motor built for a turbo? For example, are you running low compression pistons? I'm just worried if you've been driving around with an engine built for a turbo without a tune.

Engine oil is kind of preference. My tuner suggests 10w40 non-synthetic. If you built this motor fresh and put synthetic in before the piston rings seated then you might have a slight issue on your hands. Freshly built engines need break in oil and non-synthetic for at least 500 miles; after that its your preference.

 

Break it in on the dyno tune! To hell with "break in" periods. Tune it the way your going to drive it and if it blows up: then rebuild it the right way lol

 

nosir, its a bone stock b20b so it has low comp pistons but they're stock still. and i dont mean rebuilt, i just mean it only has about 50k on it. and i put synthetic in about 2k miles ago, would it be an issue if i switch to non-synthetic right b4 my turbo goes in?

 

i cant afford the blowing up and rebuilding part lol i can barely afford the turbo

 

Well thats your problem right there. It is going to blow eventually it happens to everybody. Since you cant really afford to do it right, then do not do it at all. You are going to learn the hard way my friend.

 

let me rephrase that. i mean i can afford it if it blows within a month or so..a full b20 longblock is 500 bucks but i cannot afford to completely build my motor lol thats a lil more expensive

 

Ah, gotcha. And that was my bad, I forgot B20's have low compression pistons. Yes, you can swap back to non-synthetic.

 

just stay out of boost and run a stock PCV system until you feel its broken in.

really all it will take is 20ish miles of hard acceleration and deceleration in gear and u are good to throw boost at it.

 

to an extent thats right.

i do always run sae 30 throught it, bring it up to temp varying rpm between 2000 and 3000 for a good 10 minutes then drain the oil and let it cool off.

beyond that, as long as the tune is good (or on the dyno if you are tuning) run it through its paces. my current motor was broken in like that and it has 208 psi compression off of about a 9.3:1 static and 5-8% leakdown. got like 1500 miles on it and was wide open to redline off the wastegate (9 psi about 330whp) with somewhere around 5 miles. (had to just touch up vacuum section)


its all about heat cycles. just be diligent with oil changes. it might be overkill but i do mine with like 100 miles, 500 miles, 1000 miles then onto the 2000 miles regular intervals.
