this morning i had my ca18 s13 dyno’d…the motor has just recently been rebuilt plus i added gtir injectors and an safc 2… the car seemed to be smoking blue fairly bad but only under load/boost…piston rings shouldnt really be an issue because of the recent rebuild… im thinking the turbo is on its way out…btw its a t28bb…ideas??any input is greatly appreciated! ---

did you rebuild the engine or did you have someone do it? also how much break in period did you give it? ---

i rebuilt the motor with the help of a couple mechanics…with reguards to “breaking in” the motor … i’ve barely even drove it that much since i did not have the safc2 working properly…and with upgraded injector’s it was obviously running rich, since no tuning had been done yet…im gona do a compression test 2moro so i guess i’l see what the verdict is then…if there was internal damage (piston rings) wouldnt the car smoke blue at idle too?? ---

Not always. On boosted motors it will blow a little blue when your in high boost. Sounds like rings. Did you break in your rings properly?? If not i would put my money on them. ---

Ballbearing turbo’s need oil restrictors (Smaller than Journal Bearing turbos)…Im gueesing you just used the stock lines… You may have blow a seal on the turbo. ---

> [@silvers13](#): > > i had been babying the car for proly in total maybe a few hours of driving before it hit the dyno…guess we’l find out on the compression test 2moro morning :cry you did not break in your motor. There any many ways to break it in. This is one [Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power](http://www.mototuneusa.com/break_in_secrets.htm) (lots of rev’s little boost) Or the other way is very little bost, gradualy increase your rev’s over 1000 kms and LOTS OF DECEL aka downshifting) Better start know. The first 20-50 kms are the most crucial. ---

so you drove it for 3 hours and put 800km on it? thats an average of 266km/h…anyways it doesnt really sound like you properly broke in the engine, and most likely will need another re build ---
