420a is turbo. need help

eclipse787 · #1 07-03-2008, 10:25 PM

ok so everything is installed but it smokes alot and after doing some full throtle take offs there is oil everywhere on the front side of the motor. where is it coming from? has anyone had this happen right after installing a turbo?

eclipse787 · #2 07-03-2008, 10:31 PM

and when i did drive it, it sounded like the bov was opening way to early. like around 5000 rpms. isn't it supposed to open only when i shut the butterfly?

i figured out why oil was every where. when i closed the hood i hit the oil feed flange going into the turbo and cracked it/weakened it. obviosly wasn't paying attention. so when i hit high rpms the oil pressure blew it off and i think that is why i thought my bov was realeasing to early. good to know i had large ammounts of oil spraying into my engine bay. but when i first started the car, it still smoked a little, not as bad, but definitly to much to be driving it. the directions for my oil feed kit said don't exceede 7/32 drill for the oile supply flange. so i drilled it to 7/32 thinking more oil would be better. i think i was wrong. will a 7/32 hole cause it to smoke a little bit?

More oil is NOT better when coming to the feed line. If you got a kit, it was probably already drilled out to a certain size. You should have left it that size. Too much oil puts pressure on the turbo and can cause the bearings to leak eventually... thus pushing oil into the turbo, causing it to smoke. You might want to check if the turbo is leaking oil inside and check your piping seeing if there's oil anywhere inside. And replace that piece.

i got all my lines redone and working, and i love the power my cars puttin out know. but, (of coarse) i dont know what to do with my crank case breather. before i hade the littel hose attached to my cold ait intake, like im supposed to. but for my test drives i left the breather open and when i hit high rpms and high boost, oil sprays like crazy out this hole. being that i just rebuilt the motor im hoping there isn't to much blow by (stock compression) so do i need to lower the boost until i get really nice rings, or can i just put a breather system/catch can in with a hose coming from the crankcase breather line, to a catch can with a filter, then back to the valve cover? im pretty sure that would work for keeping the oil in the motor and still having the crank case breath.

Most people use catch cans. I still have a filter on mine, but then again I haven't been hitting boost at all really.

What psi are you running at?

eclipse787 · #7 07-08-2008, 01:54 PM

apparently i had my wastegate hooked up wrong and was running close to 25 psi. ive spooled up around ten times, and guess what, my rings are fried. 50 pounds in two cylinders and 90-100 in the other two. car died about 150 feet after the last heavy boost. car doesn't even atempt to start now. checked the timing so i know the valves are doing there job. guess thats what i get for running a turbo on stock internals. so what i want to know is if i NEED low compression pistons or if i can get these rings-http://www.cimotorsports.net/motor-sport-products/total-seal-ring-set-eclipsetalon-420a.html i just spent alot of money on the turbo and really can't afford an eagle/je rod-piston setup. i'm hoping these rings will hold up the 5-6 psi i'll be running when my wastegate is setup right. what are your guys' suggestions?

david-b · #8 07-08-2008, 02:15 PM

How did you not know that the WG was setup wrong and that you were running that high? Did you have a boost gauge? Why were you hitting boost so hard when you knew there were issues still? That's just asking to break something. What did you use to tune with?

You will have a lot bigger problems then just rings. And now that I'm typing this, what turbo do you have on and what fuel setup do you have? 25psi is no small fry and you need A LOT of upgrades to hit that on any turbo. Enlighten me please. You should have hit fuel cut long before that especially if it's only setup for 6-7psi.

eclipse787 · #9 07-08-2008, 02:34 PM

i didnt have a boost gauge at the time. and know i cant even use it now that i got it. the turbo i got said it can easily do 25 psi, but the wastegate was set to 8. i dont know a whole lot about turbos yet, but i dont see 8 psi destroying rings on a 250 mile motor. its almost brand new. i know 25 psi is ALOT and would never knowingly run that on stock internals. i talked to a ci-motorsports mitsubishi tech and he told me the hastings ring set works great on stock pistons. i want to know from all of you what are the must haves for daily driven turbo cars? do i need a safc and other controllers, or are these just for making more power?

david-b · #10 07-08-2008, 03:11 PM

Rule number 1... get a turbo, get a boost gauge.

You just said you did 25psi. How do you know?

So you have nothing controlling your fuel? What's your fuel setup?

IF you did run 25psi, you would've blown a stock motor easily... 250 miles or not.

I'm wondering if you damaged any other components or significantly weakened your rods

what turbo is this?
What is your fuel setup?
What are you tuning with?

Im raising the BS flag. There is no way you got 10 runs in on 25psi. The motor would have blown before it even hit that much boost. Let alone do it for 10 runs. The rods break at 13psi. I want a mod list and maybe some pics to.

eclipse787 · #13 07-09-2008, 05:04 AM

ok, what i meant to say was that because the turbo CAN do 25 psi it might have reached that high(JDM T3 A/R50) right now i really dont know how much psi i was running. i have all stock fuel supply and right now nothing controlling it or the air. the wastegate is supposed to be set at 8 psi. maybe it was working and the stock rings couldn't hold that 8 pounds.

SilvrEclipse · #14 07-09-2008, 07:03 AM

What did you use to inject the extra fuel you needed with boost? If you ran nothing then that was your problem. At the bare minimum you will need a bigger fuel pump and a 12:1 FMU and that would be fine up till about 7psi of boost.

david-b · #15 07-09-2008, 10:36 AM

JDM T3/4? We talking a eBay turbo? As Silver stated, even if the turbo is rated at something, you didn't get the fuel that it needed. The injectors got maxed out a long with the fuel pump and I'm pretty sure you hit fuel cut after like 5psi. Stock fuel system sucks. Stock rings can hold 8psi and up unless you run it massively rich causing them to basically melt. But you weren't getting fuel in there so I'm pretty sure you ran lean.
