I am considering getting a greddy one because they are fairly cheap (70-80 bux) and wanted to know do I need to get a harness also? I have no idea how to install that thing since there are no kits for the miata. They have a universal turbo timer but I have no idea how to get it to work with our ignition and what not.

They are super easy to wire up.
You don't need one though. If you use synthetic oil and let your car idle for a few seconds before you shut it off you'll be fine. I was told by Corky that as long as you don't shut the car down immediately after being in boost you don't have to worry about oil coking. If your turbo is jacketed for coolant you should also get the turbing and fittings too hook that up as it will also help with this. I let my car idle 10 seconds before i shut it off just because i like wasting gas , no oil coking problems thus far.

sorry to hijack but i got my water run thru mine and run syn do i have permission to shut down right when i pull in the garage? this turbo seems to be spooled up constantly so its hard to keep it from spinning super fast.

I always use super synthetic oil (usually mobil 1 ) so leaving it on for 10 seconds is good? Ive heard some horrible stories from people who didnt leave it on for a couple minutes lol thats why i was considering one

Everyone that has done studies on this or has had alot of experience with turbochargers in general says its ok to shut down when you park, especially if you have coolant going to the turbo. I would still let the car idle a few before shutting down, but no more than 30 seconds. Synthetic oil doesn't coke like dino oil so that solves most of the problem in itself. If you let the car run a second after boosting before shutting down, the oil that was heated up so much drains from the turbo so it shouldn't be a problem. There was a long/large discussion on this forum about this previously as well. A good search might dig that up, about turbo timers or coolant passages i can't remember.

The one I was thinking of.

Should answer most questions.

If you can get one for cheap,I say get it.
There is no harm in not having one,hell I have one.

turbored

I had one, but i pulled it because it made the dash look cluttered.
It's nice. You can warm up your car, or cool it down with a/c when it's hot. Plus people look at you funny when you leave your car running.

Exactly. A turbo-timer is the most overhyped product in the aftermarket tuner world. No, it can't hurt. No, you don't need one. If they did anything at all, Begi or FM would carry them.

Spend your $80 on a cheap digital camera so you can upload pics to your vbGarage.

lmao at spamnavy dat was a low blow dude haahahah

Some are nice though, like the Apexi one. It comes with a NB O2 gauge, volt meter, some other ****, and its a turbo timer.

i turn off my car while boosting just in spite of all the hype.

you really don't need one. They're more for "look at me, i've obviously got a boosted car"

After about 50 "hey man your car just shut off"..you'll get tired of it. Just dont abuse your car then immediatly cut it off.

For the guy with the BB turbo, same story. Even though it's always spinning doesn't mean its always under extreme heat. Heat is built up by exhaust gas, so just take it easy the last minute or so before you shut the car off.

Personally, if I'm say at the drag strip and I just did a run, I'll let the car run for a good 2 minutes before turning it off, or after an extended amount of time on the highway. For normal city driving, you probably dont need to let it cool down at all.

Three things:

1. If Braineack offers his turbo for sale--don't buy it.

2. I use one for the convenience of not having to sit and wait. And; it is a pain to have other people tell you you car is on.

A couple of times I have gotten out of the car with the engine still on(key in ignition) and didn't realize it until I returned an hour later and it was still running. When you get used to the engine running on the timer, you don't have the reminder of the noise to remind you to pull the key.

3. I forgot number three:gay:

Number Three. Found that my ignition switch contacts needed cleaning real bad when I put the key back in and started driving and my car cut off when the timer timed out.

(It was only running through the timer)

i've only rebuilt it twice now. :gay:

The alarm system/remote start that I am about to install (Viper) has a countdown timer built into it, so I'm removing my APEXi. But I like the extra security that comes from knowing the car has been properly run-down, even if it needs it or not.

Letting the motor sit at idle is not without its own abuse.

It would be interesting to see any data comparing excessive idle vs hot shut down on synthetic oil. I would bet that there is less wear from hot shut down.

My cool down ritual is the time it takes to drive into my neighborhood, into the driveway, and wait for the garage door to raise.

I currently use a apexi turbo timer (about the size of magic marker). I have my turbo timer on auto, to stay on for a minimum of 40 seconds and automatic sets it time for a longer period of time if the car has been run hard. Usually, the car shuts off before I am finish removing my work equipment out of the trunk and walk away from it.
