i really couldnt say mang....but imho running a better radiator would be a little easier than having to worry about higher oil pressure levels....too high and you could blow your turbo seals...just a thought.

 

i would do the radiator first especially on a watercooled turbo.. i still would want an oil cooler right now if only i have enough space for it

chris, how much oil pressure increase did you notice with the oil cooler?

 

i only see higher levels on cold starts and it takes the oil longer to warm up to proper operating temps. i get high 60's at idle on initial start up. ive even seen it at 70's on a slight rev to 2000rpms. it only gets worse the colder it gets outside, I mean it takes much much longer for the oil to warm up. Like i said before though it really made it worth it at the track, though i think a mish radiator would have done the same job. I do think the oil cooler helps to cut my cooldown time befor i shut the engine off.

 

hey thats not even noticeable.. my cold start is 50-70 too.. pretty much same oil pressure as without the cooler.. prolly 10 psi over than stock when cold, not bad at all.. especially on hot tx summer, i say its good to have one to make your car happy and still not afraid to gun it after several pulls

 

it does make me feel better that i have it when i go to the track......speaking of which im going this sunday.....you coming....(prolly not..lol)

 

nah im back to work already lol..

 

just like i thought..........lol
j/k

 

Perma cool makes a nice inline oil thermostat that will keep the oil from going through the cooler until its hotter than 180F. Its about $40, that would help you with your warmup.

If you have an oil temp gauge and are getting really hot temps for prolonged periods you may need an oil cooler.

A better radiator is often the best first approach as it will help with oil temps, not adding extra things that can leak( as long as a good unit and properly installed, etc) as well as most likely less weight added.

I have a Koyo, a bit more costly than the Mishimoto(which I do not know much about) the Koyo is the manf of the factory radiator, a very good manf and no worries about the unit if you go with them.

If you do not have an oil temp gauge and running long duration events then I would recommend getting one and seeing what the real temps are. If not an issue then save your money for something to actually make you faster or more reliable.

I won many races over the years with underpowered cars that weighed as little as I could get away with in the rules, ususally pushing the limit of what was legal, never busted for it

If you have not done so I would remove the balance shafts(make sure to plug the oil feed hole) and then you can add more oil which is a good thing. Between a custom aluminum flywheel, the right pulleys and removing the balance shafts my engine revs up like mad compared to stock. That equates to much quicker corner exits on the track and a big reduction in lap times Cost, $0

--------------

A better bigger) radiator will hold more fluid, add a bit more weight than stock but a worthwhile trade off if needed.

 

Chris-

if your going to upgrade your radiator (which is a good idea, way before an oil cooler)

let me know asap as it will change your coolant lines for the turbo.

Regards-

Todd

PS- if you do buy an oil cooler/relocation kit do not install it until after the turbo install

 

watching.

 

Yep, radiator first, then oil cooler, in that order


Just no need for a relocated filter, added weight, more to go wrong, pointless on the tC.

 

You know if you go all the way to the bottom of a thread, on the left side. There is a link that says "watch this topic". Just letting you know so that i'm not geting topic notifications every time you post "watching". lol Get me excited for no reason.

 

^^ haha he knows that, he's just checking in!

Oh and todd the mishimoto rad fits perfectly even with my coolant line! :D

 

just looked at it......nice looking out bro.
i may look into that as mola comes in.

 

yeah permacool have some really nice stuff.. and summitracing, their aftermarket catalog is great especially in the cooling section

 

hmm.... so I can use that inline oil thermostat with the mishimoto oil cooler????

 

look at the fittings on the mish...are they 3/8?
i dont think mine are (non mish..lol)....id have to look and its too cold, im also lazy right now.

 

Why not get an adapter plate with a built in thermostat? Less connections, probably less weight , certainly less chance of leaking with the fewer connections.

 

Todd thanks for the heads up but I don't think I'll be getting that radiator anytime soon. A little low on funds. Btw way will I have an issue later after I get the turbo as far as the whole coolant line thing?
