I have a few questions i need answered asap.


1. I know this has been covered before but I want to hear stories from folks who done it or did it,Is it safe to turbo an itr motor?

2. Can CP 12.5 compression b18b pistons work in a b16??

3. My b16 has a knocking rattling from around 200rpm upwards after i ran the shoot out of it one night,also it wont idle.what could it be?im thinking con-rod bearing??

thanks..

 

yes you can turbo a b18....been done over a million times
pistons will work
if your car idles at 200 rpm....thats just not right

 

I know can turbo a b18 but im wondering about a type r as in DC2 motor???Im worried about the high-compression..

typo sorry..I meant 2000rpm..getting tired lol

When its cold it will idle fine but knocks from 1500-2000rpm upwards.vtec is coming in.When hot it wont idle at all and takes long to start almost like a dead battery but yet the battery is almost new.I even recharged it to make sure.

Ideas??


97 civic Si with b16

 

do you have a rev limiter, and oil level good

 

oil is fine,coolant is fine.No CEL's.I havent reved it up to redline since its been rattling but its normal redline for b16.stock ecu.

 

does rattling sound like bb's in a can

 

Kinda yea i guess...im afraid its a con-rod bearing..sounds almost like something loose and rattling but yet everything is tight and the sound is definitely coming from the bottom back of the motor.

 

pull your oil pan off and check to see if there is any play where the rod connects to the crank, if there is, pull the cap off and check the bearing.....if itsounds like bb's check the timing could be detonating.....what grade gas you run?

 

sounds like a spun rod bearing bro ive experienced it myself and on friends cars. not a happy sound. And also turbocharging a stock ITR engine is a terrible idea. compression is way to high to begin with. Unless you knock the compression down with diff pistons you'll be asking for a blown motor

 

Im going to drop the engine in a bit to find out whats up.I need to change the throwout bearing anyway.

Anymore suggestions before I go start?
