Exclamation Turbo Timer FAQ: Read if you are thinking of buying one!
Turbo Timer FAQ

The primary purpose of an aftermarket turbo timer is to allow your engine to idle unattended for a user specified amount of time. This will allow your engine, specifically the turbo, to return from elevated temperature levels to normal temperature levels prior to the engine being turned off. This can prevent oil coking in turbochargers that are cooling by engine oil.

Are these necessary with Subaru Turbos? No.

June 2001 TechTIPS published by Subaru for Subaru Technicians states:

"2002MY WRX TURBO COOL DOWN PROCEDURE
FHI's position regarding this is that it is not necessary to perform a "cool down/idling" procedure, as was recommended with past turbo models. Our current 2.0L turbo engine has a far greater cooling capacity and, coupled with technology advances, makes this practice no longer necessary. This explains why information about cool down is not included in the 2002MY Impreza Owner's Manual.

The heat contained in the turbo charger will begin to vaporize the coolant at the turbo charger after the engine is stopped. This hot vapor will then enter the coolant reservoir tank which is the highest point of the coolant system. At the same time the vapor exits the turbo charger, coolant supplied from the right bank cylinder head flows into the turbo. This action cools the turbo charger down. This process will continue until the vaporizing action in the turbo charger has stopped or cooled down."

Which manufacturer is best? This topic is highly debated. There have been no reported consistent "bad" turbo timers on the market. Obviously, there may have been bad timers sold, but not enough to report as "bad" overall.

Are there any downsides to turbo timers? There have not been significant amounts of problems with turbo timers. It goes without saying that repeated use of turbo timers has obvious effects on gas mileage.

Are there other uses for turbo timers? Yes. A turbo timer makes a great tool to warm up your car during cold days. Jump in, start your car, set the timer, remove your key, exit the vehicle, set the alarm, and enter a toasty vehicle 10 minutes later. It can be a more appealing and cost effective option than conventional remote starting devices. It also eliminates all thought of remote starting in gear (though there are safetys for this on remote starting equipment) for manual transmission vehicles or entering a cold vehicle because you forgot to set the climate controls prior to exiting the vehicle the night before.

Where do I buy turbo timers? Every Subaru/Import performance store sells turbo timers. For purchasing, support your local economy or the NASIOC Vendors.

How hard is it to install turbo timers? Allow around 1-2 hours for install time. Professional installation, depending on your area, is around $100. This is one vehicle modification that is very simple and can be successfully accomplished by even the greenest shade tree mechanic.

How do I install turbo timers? Refer to the turbo timer manufacturer's instructions. For turbo timers without instructions, below is a link to some of the better known turbo timer installation instructions:

nasioc.com instructions (with photos) catered towards factory alarm users

Editors Note

This post was created because I wasn't able to find a good turbo timer FAQ. I came up with the text based on LOTS of searching here. Upon reading this you should have an idea of whether a turbo timer best suits your needs or not. The manufacturer is up to you.

 

Stop wasting your money on pointless things laundry boy. That's money you could be spending on flaps or your stereo.

 

There is your problem, nasioc. Anything and I mean anything you read there, is suspect and may, and very likely is, total BULL****! *stealth edit* even when they are right, check other sources. In this case, no, you do not need a turbo timer.

nasioc is like pirate4x4 only, everyone is full of **** and every bit of tech is crap.

 

how is it wrong in this case?
it says it is not needed for a subaru turbo then tells you how it works if you were to buy one

 

Its cool, save your money. You don't need it. If it was needed, don't you think all turbo'd cars would come with one from the factory? Or at least the new fleet of subarus? Lol

 

You mean like good OEM ring lands or ECU tuning?

 

Yea man, those are needed though! To be a Subaru!

 

Does not apply to a 2015 wrx, the new FA20DIT engine has not have any reported incidents yet of failed engine parts. The only reported problems have been ECU related and those have been fixed with simple reloads at the dealer.

 

I am waiting for the timing chains to go *SNAP* under hard load.

 

I will hold your hand on this. You do not need a turbo timer. No modern Subaru needs a turbo timer.

Your turbo is water and oil cooled. It doesn't need to sit and cooldown. You don' t need it. You don't even need to "warm up" your car. Read the owners manual it will tell you this. In detail.

Did I remind you that you don't need it, cause you don't.

If you really want to **** away $125 send it to me and I will use it.

 

Did someone tell you that you don't need one yet?


What you do need is a nitrogen cooling system.

 

That would be because they went back to a 2.0L design that did not have the same issues that so many of the the 2.5s do.

 

They also didn't have the issues with 04-06's and early 07's that had 2.5s. There was some crappy decisions made that affected later 07's+ in the name of cost savings.
