So I went with the on3 76mm .96/.81 ar t4 and it **** itself. Throwing the oil out the exhaust and all. Not worth rebuilding since it's so cheap so I was going to try that gt45 from ebay that I see some people using. Now the question is.. The on3 turbo has an undivided t4 flange but the gt45 has a divided t4 flange.. what's the difference? Pros and cons of switching to this turbo? Goal is 10-12lbs of boost if I ever get a chance to finish the damn thing.. any input helps. Thank you

Hmm. What size return/feed are you using?
Any pics of the setup?

cjvmboricua08

I went with modular turbo feed and drain with a scavenge pump.

Got pics on my email and on my phone.

Use photobucket to upload them.
How many miles on the turbo?
Any in and out shaft play?

cjvmboricua08

Haven't even finished build. 5 months in. does have a driving tune for work, around town and that's all. No shaft play at all. Just bleeds out the oil. Noticed when my bov started blowing oil and turbo housing went from silver to gold lol

I'm thinking its something wrong with your oiling system

cjvmboricua08

Pulling too much?

Is it a rear mount setup?

Pics speak 1000 words.

How does the motor run ? Any major blowby ? Boosting on the motor with no tune ?

cjvmboricua08

Give me an email and I'll forward the pics. Front mount. 7Lbs but I stay off of boost. Motor runs ok not it's best. I went from stock injectors, maf to sd, so the little tuning I was able to do was to adjust fuel and a little driveability because it's my dd and only vehicle. Another factor was that I was heating up which I'm leaning towards thermostat. Switched to dual pushers and thinking about adding same as pullers. Texas heat is no joke!!! So original question.. ??? could I use that gt45 divided

a4ls2goat

Yes you can use it.
But I don't think thats your problem imo

cjvmboricua08

Should I try a restrictor?

a4ls2goat

I really don't know much about oil pumps.
Maybe some one with more knowledge can chime in.

cjvmboricua08

that would be nice!!

cjvmboricua08

on the first one you can see where the pump sits a couple inches above turbo and on the second turbo you can see the shiny oil spots all around the turbo and bov
