I converted to a manual long ago..and just plugged up the tranny cooler fittings in my radiator. I'm also running twin turbos..heats the hell out of the oil.

Is there any reason I can't (or shouldn't) run my turbo oil lined through the stock in radiator tranny cooler first...then through the turbos?

I'm currently seeing way too much pressure at the turbos anyway...so I'm not worried about a pressure drop.

I think its a good idea. Ther shouldent be enough pressure to blow a line off or anything+ you get some extra oil capacity. Im debating if I could use an oil cooler as a fuel cooler for the summer months. Think that would work?

Sure, why not? The only problem I can see with doing that with fuel is if you get in an accident and where the cooler is. A friend and I put a fuel cooler on his dads motorhome yearsssss ago because of a vapor lock problem with it, and it worked on that so I'm sure it dropped the fuel temp.

Just be careful in where you choose to put it, dont wanna see no fires! Fire bad!

And Jester, yea that will work too, just make sure the tranny cooler dont leak or you'll have coolant in the oil... bad.

yes, there is a reason. trans cooler lines are much smaller and require considerably higher pressure to handle the higher volume. this is why oil cooler lines on a vehicle are 1/2 and up to 5/8 hoses depending on application. it may be a good idea off the turbo lines, but not likely going to cool it that much. if you put twin turbo on it you should have had the money to put a real oil cooler on it.

 

Jester, I'm -really- interested in your twin turbo setup!!! I'm debating wither I should sell my 2.8 to be able to buy a 350 Trans Am quicker, or just save up and buy one and keep the 2.8 and turbo it as a project... If I'm going to turbo it it'll at least be twin... Do you have a site, or some build specs you could share? Or maybe even just a pic?

The lines feeding my turbos now are only 1/4"...and they don't have enough pressre drop at the turbos. The turbos still see 40 psi even when hot with 5W30


What size lines are the tranny fittings anyway?

 

Zenodrgn....follow the JSP motorports link in the sig. the pics are outdated....but it gives you an idea.

No particular reason it wouldn't work. Are you talking about running the return line that way? That would be about as fool proof (me-proof!) as possible since there's almost no pressure at that point.

No the return lines need to be free flowing. The only way I could put the cooler there is if I used a scavenging pump to help pull the oil through. I'm talking about running it from the tap in the block, though the cooler, then up to a T fitting, then to the turbos.

 

That would work too, as far as it goes. However, I doubt the cooler would add any significant amount of restriction (back pressure) in that line. It's pretty big, alot bigger than the #4 and smaller lines that are usually used for the turbo feed & return. How much oil is going to be flowing that way anyway? It isn't usually a huge amount.

And it does seems like it would make the most sense to send to the cooler the oil that just got turned into the hottest in the engine (by way of having picked up however much heat in the turbo), rather than just go through the motions of pretending to cool oil that's already at the normal temperature. That's how the cooler works for the trans... the oil that's forced out of the converter by new oil being pumped into it goes to the cooler on its way back to the pan, after it gets heated up by the converter which is the hottest part of an auto trans.

Well there are 2 problems with that,,besides the back pressure issue.

For one..the cooler fittings are above the turbos..gravity feed won;t be too efficient.

Also while the oil is hottest leaving the turbo, the oil being too hot inside the turbo is worse. It'll coke and clog the return lines...the one was cloged up as it was when I pulled it from the yard. I'd rather have it going into the turbo cool..give myself some extra room for it to heat up.

Jester, Im tinkering with the sigle turbo idea on a carb setup. How would you induct this setup?
Are you using a carb?
Any insite would be apperciated!
