sup guys,
im about to put on my new garrett turbo,do i need a period of time to break the turbo in,or can i bolt it on and go to town?

Installation and pre-oiling of turbochargers.

1. Remove old gasket form exhaust manifold mounting flange, inspect flange for erosion and flatness and install a new gasket.. if used.

2. Inspect oil dran and supply lines for kinking, clogging, restrctions and other signs of deterioration.

3. Install turbocharger on engine using all new gaskets and O rings (when needed) but do not connect the compressor inlet and oil supply line. Tighten the nuts or bolts attaching the turbocharger to the exhaust manifold to to the toqrue values given in the shop manual. Use of a high temperature lubricant on these threads is recommeneded.

4. Fill the oil inlet hole with clean engine oil and spin the compressor wheel several times to coat the bearings with oil. Refill the oil inlet hole and connect the oil supply line.

5. If the compressor wheel cannot be supn freely by hand or if there is any indication of rubbing, scraping, determine the reason before starting the engine. One cause of wheel rubbing is a cocked compressor or turbine housing. T04 and T04B turbochargers may have a slight drag before running in, which is a normal condition. Connect the pipe or hose from the outlet of the air filter to the compressor inlet.

6. Check lubricant level in engine crankcase

7. Primer the oil filter if it was charged.

Starting the engine.

1. before attempting to start the engine, crank the engine with the fuel shut off for 10 to 15 seconds or until the instruments show an oil pressure buildup.

2. Start the engine and allow it to run at idle speed for 3 to 4 minutes before accelearating.

3. CHECK FOR OIL LEAKS

There is no point in cranking the engine to build up pressure. It will never happen and even if it does it will not be significant. Just start it up and it should be at 75 in 3-5 seconds

very informative...i never done that for any of my turbos except where you start it up check for leaks idle for 15mins then i go to town on it hahaha

komat

if i just crank my motor over and over
i can make about 10psi of pressure

i let it idle for about 5 minutes, then go all out

1.if your engine gives you 75 psi of oil pressure at idle you have problems...

2.you should crank the motor to build oil pressure...remove the spark plugs so the motor spins freely and it will build pressure

At cold idle my engine builds 60-80 psi with no "problems".

1,000+ posts and a 600hp car, but you still don't know at cold idle you're going to get 75-80psi of oil pressure?

it depends on bearing clearences, if the oil pump is shimmed , start up rpm type of oil ect.... so try not to be a smart ***

ive seen many cars not even come close to 80 psi at idle.

not to forget most cars dont idle at 900 rpms when its cold....


and to answer the question of the thread....

id try to put some miles on the turbo before you start boosting...

O16581724 5 2 5

Most cars don't see 80psi period, every Honda i've owned and every person i've talked to with one says they get about 80psi at idle.

thats strange considering the specs in the helms are about 10 psi at idle and 50 psi at 3 grand...i believe these are the lower limits but still....80 psi at idle seems extreme

O16581724 5 2 5

We're discussing cold idle.

10psi is normal for fully warmed, doesn't your 600+hp car have an oil pressure gauge?

no YOUR discussing cold idle ...if you look agian this thread is about BREAKING IN A TURBO and the reason this started is someone said "you cant build oil pressure cranking the motor" which is not correct.....

the car should not idle at 75-80 psi of oil pressure and I never said cold idle ...the cold idle is higher but still not 80 psi....

so save the stupid comments

You sparked the debate, no reason to **** an attitude with me.

75-80psi is what it's supposed to be at cold start up, end of discussion, just admit you're wrong.

And yes, you can build quite a bit of oil pressure cranking the motor, i've built as much as 30psi cold cranking trying to get the car to start after i rebuilt the motor. I had the timing off and injectors wired wrong, heh.

so why do you keep making sarcastic comments about my car which has nothing to do with this?? especially if you cant put a car on timing or wire injectors

there was no reason for the stupid comments .... if you would like to state you disagree with me about the oil pressure just say it without the immature moronic comments

O16581724 5 2 5

I screwed up a few things putting an engine back into a car, big deal, bugs happen. I discovered my problem after checking those two things, i brought my injector harness in from the left insted of right, i'm not sure if i did this, or a friend that was helping me do wiring, i also had the firing order wrong, i looked in my Haynes for the order and it said "1, 2, 3, 4" in the picture and starting at the bottom. I was like "Uh, how does that work?", after trying to start it, i kept reading and discovered "Firing order: 1 3 4 2" written afterwards.

You have a 600hp car, you should have an oil pressure gauge in it, if you watch your gauge, it will hit 70-80psi on cold start-up.

I dont know.. I guess you must be some sort of engineer or something? Maybe you should call up the guys at garrett and tell them a thing or two since there the ones who WROTE THAT!!

To garrett for detailed instructions

lol

very few cars have oil pressure gauges. and ive never seen one fail because they didnt have an oil pressure gauge...

and most dont come close to 80 psi of oil pressure at idle. cold or not here in florida...and trust me, ive been in a lot of turbo hondas

O16581724 5 2 5

Not having a gauge for oil is stupid in my opinion, especially on a heavily modified car. I've had a my oil run low and it saved me, my oil pan gasket split when my car warmed up, this caused oil to pour out, had i not had a gauge, i wouldn't have known and drove the car, i noticed a dramatic decrease in oil pressure, i took it easy home.

Why do people argue with me when i state facts?

Most cars cold start about 2,000-2,500rpms, mine cold starts to 3,000, my oil pressure is at 80psi until the car has fully warmed and it slowly drops to about 20psi. Shoot, the car cold started to 75psi on a crank with all the main bearings worn way out of spec before i rebuilt it.

dude, come on, ive tuned way over 100 cars, none of them come close to idling at 2500 when completely cold.

they are around 1400-1600.


if your car starts at 3000 rpms when its cold, that is def not normal.

your car idles at 3 grand when you start it??? you should stop stating facts already .....
