did you check for any boost leaks?

 

i checked all the couplings they looked ok where else should i check... i am really starting to think that it has got to be the fuel injectors.. i am going to upgrade to 550cc... i dont get it because my boy has an sr20 with a t25 on 16lbs. and he has no problems...

 

evey car is reacts different to mods. even the same motor with the same mods. the white smoke prolly turbo seals sense oyu not coplaing of over heating. the black smoke on higher boost you may have a boost leak. you need to make a tester and hook it up to find out, the couples may look good but under the higher presusre it may be leaking. adding bigger injectors may make it worse. if theres black smoke now bigger injectors will mean more black smoke.

 

Blowing white smoke at idle might suggest that the turbo seals are going. It's pretty common for turbos to smoke a little, especially at idle when the seals are about to go. There's not too much you can do in this case, I'd just leave it be till it starts smoking consistantly.

As for the car breaking up. There are a few things you should check. The first thing I'd check would be boost leaks, start with your intercoolr couplers. How old's the intercooler setup? Cheaper couplers has the tendence to dry rote and or crack. From there, check all vacuum for any leaks. Doesn't really sound like bad injectors to me. I'd also try what DriftingDJ said, get new spark plugs and regap before installing.

 

Yes please check your spark plugs before anything else. Use NGK's

sounds to me like a few things.

1) NGK BKR6E gapped to .028.. not 30
2) turbo seal might be bad. if they are, not only does it smoke at idle, but also smokes on decel when you let off the gas, but usualy not when youre on thegas.
3) i recommend a headgasket check. any decent shop can do it with the right tester. i have one.
4) check for boost leaks for sure. make sure your BOV isnt leaking, no couplers are leaking, etc.

 

I Finally Found Out What My Problem Was With The Breaking Up On High Boost... After Checking And Replacing Many Fuel Componets Thinking That It Was A Fuel Problem.. It Wasn't, I Started To Think Maybe Coil Pack But Then It Would Always Break Up.... So I Started Checking For Boost Leaks,, All Couplers Good.. Bov Good.. I Have A Manual Boost Controller And It Wasnt The Hose To It.. It Is The Boost Controller Its Self.. I Guess There Is Like A Little Gasket Inside That Went Out... But Its Ok, I Just Made The Credit Card Bill A Little Higher.. I Ordered A Brand New Stage 3 Clutch, Turbo Timer, Boost Controller, And A 5 Quart Oil Pan... So I Cant Wait Till It Comes In... Of Course I Have To Wait 500 Miles For The Clutch To Break In But After That, I Will Be Back In Action,, Thanks For All The Help Guys... Pretty Soon My Babe Will Be Back On Her Boost....

 

Good choice on the oil pan SR's love as much cool oil as they can get!

 

glad you got it figured out.
