Default Going synthetic

When I install my turbo (Next weekend!!!!!!!) i'm planning on changing to synthetic oil. What kind should I get? 5w30? I'm not even sure what all the numbers mean. I live in Michigan, so we see all kinds of temps, if that affects anything. I'm planning on going to synthetic ATF also. Either Amsoil (hear it kicks heat out REALLY well) or Mobile 1 (heard it shifts harder/better ). Any thought's, opinions.
Thanks guys.
Mike
P.S. At the moment i'm not planning on a tranny or oil cooler, don't have the guages either.

Don't know about the atf but for engine oil amsoil 5w-30 would probably be good, I assume there's not going to be a massive heat wave in minnesota this year , so go with the 5w-30

If I lived in Michigan I would run 0w 20. You don't have to worry about alot of heat up there, so I'd go with a lighter oil.

right but he's installing a turbo, I believe you need to step up the weight in this case.

Oh Wow. I missed that. My bad. 5w 30 sounds about right.

You should definitely look into getting a tranny cooler. They aren't that expensive and it'll only help.

As for synthetic ATFs..I'm using Royal Purple. Shifts are smoother and a bit harder, downshifts are definitely firmer.

An engine oil cooler is always a good idea when you've got a turbo. And from what I've heard out of all synthetics Mobil 1 is tops.

Default oil and tranny coolers

I want to get an oil cooler and a tranny cooler. But i also want to get a heat exchanger for the water for my intercooler too. So if I mount those 3 things in front of the radiader, there will be only 1/4 of the radiater left to cool my engine, and with the turbo it will have more to cool down. Having all that didn' t seem like the best idea. Especially with no absolute need for oil/tranny coolers. That's why i'm switiching to synthetic. To get all I can out of what I have now.
Thanks for the help.
Mike

You don't have to put them in front of the radiator. And you don't have to use a air to oil cooler. I use the factory subaru coolant to oil cooler, and it works great. I like it cause you don't need a thermostat, like your suposed to use in a air to oil cooler

An engine oil cooler surely can't hurt, especially if your using the oil to cool as well as lubricate your turbo (as many of the aftermarket kits do). However, if you're running synthetic, I don't think it's a "must do" type of thing. I've run my car at 2 track events and my engine oil hasn't gone over 230F even after 30 minutes of on-track abuse.

Actually, my sensor is in the drain plug, which makes the readings susceptible to false low readings while driving. I've noticed that when stopping and idling, the oil temp. reading will go up about 30F typically. I have video tape of my gauge from the track that never shows the needle heading north of 200F, so I'm giving worst case temp. After a cool down lap and then idling in the pits, the oil temp. was reading 190F.

FYI, in my case, mobil1 is not tops. I switched to NeoSynthetic driveline fuild and Valvoline 10w-30. This is a change from my previous combination of Mobil1 15w-50 and GM SyncromeshII (synthetic). Performance is much improved. Car just gets up and goes better. Also runs cooler. Also, it seems that the Mobil oil breaks down too fast. I found my self changing the oil every 1500 miles to keep it clean. I know the insides of my block are not that dirty. I use a Napa Engine flush treatment every other oil change (don't worry, its good good stuff). I switch to the Valvoline and the oil is still clean 1000miles later..... hmmmm....
