Turning my 1982 Porsche 911 SC Targa to "the one i always wanted"

Hi Twigs,

The euro bumpers do look pretty nice. I really dig'em. Not at the top of my priorities list but it's something I've considered. The normal bumper has kind of grown on me. My next plan is a few simple exhaust mods and shifter mods but I'd really like to go with a euro bumper setup. I think before I do that I would actually go with a front-mount intercooler setup. The easy way to do it would be to get a 930 bumper and get it mounted. Then get rid of the stupid trombone cooler and move to a front mount cooler which is a really nice temp difference.

just make sure what ever you do, You can un-do!

Front intercooler setup would be sweet, i remember seeing some sort of Air scoop on those particular Porsches similiar to the old MR-2's

But i'll be damned if i can actually find a picture of a 911 with what im talking about, so it was probably a one off type of deal.


I assume on the 930' your talking about those slantnose models with the wide open mouth along the bottom? Man that would be sweet, especially with a nice shiny a@# intercooler sitting inside.


You thought about adding that famous giant duck wing on the rear?

I'm not a huge fan of the ducktail except on the 2.7RS models. I kinda like my whale tail, always wanted one with a whale tail. The scoop I think you may be talking about is molded into the tail, the RAUH-Welt models use them a lot for cooling.

The scoop I'd be implementing if I don't end up with a front-mount oil cooler would be to remove the passenger side signal (2nd signal) and put a scoop in there. They seem to work really well. Especially on days like today where it is super hot and driving long distances on the highway results in 220+ temps lol.

All 930 models had those similar front mount oil cooler setups just because they'd get so much hotter than the regular 3.0 NA models. Slant nose was just a factory body setup, but a lot of the 930 models had those bumper upgrades. The other common "Cool thing" to do is to get an RUF front bumper conversion which not only LOOKS really nice but had a huge front area for an oil cooler setup, so that would be a huge improvement.

My only thought on that is that because this is a winter car as well (driven all times of the year) that may be overkill in the winter. Then again, it's a thermostatically controlled oil cooler anyway, so it isn't like it's going to overcool since the car in the winter time still reaches close to 200F once it's warmed up, it just takes a long time to get there lol.

oh something more like this?

although i think thats a intercooler and not a oil cooler.

not so much poking out the front, behind the bumper more, but yeah, front mount oil cooler like that would be cool. Think I'll try the turn signal removal and put a scoop in and see how it affects my temps first. Then go from there.

I like that bumper above btw, looks good.

Didn't they have 911's with slots in the rear quarter panels in front of the tire tubs?

http://cyberdesignconcepts.com/guent..._slantnose.jpg

lol looks like a awesome place for a oil cooler and A/C Cooler on the opposing side if i've ever seen one. But something tells me thats a crap load more work and money to get that changed.

Unless your brave enough to buy some scoops and take a skill saw to a vintage Porsche that is...


I'm going to have to start a thread on this 86' lincoln we've been working on. new control arms, new bearings, new ball joints, new bushings all around, new struts, sanded polished and sprayed the frame, cleaned and sprayed the springs, new suspension bumpers, new A/C pump (re-filled with R-12 mwuahhaha industrial licence) new radiator, new distributor, new coil, new cables and iridium plugs. replaced the carpeting in the front lol it goes on and on.

Currently taking out the crap engine driven clutch fan and installing two electric fans. Hah we took it around the block with out the engine fan installed one day and it hauled WAY more ass then it did before, so that fans got to go man! We've just got to figure out how/where to place a thermister and a control circuit of some type for them electric fans.


We've basically went back and repaired all the damage and lack of maintenance he did to it as a teenager.

Now we're starting to pimp it out with better parts.

Alright so I went ahead and did a few things for the oil cooling.

- Ordered an oil cooler scoop for the 911 today
- Cleaned off the brass lines with steel wool on the oil cooler

After cleaning up all the oil lines with steel wool and getting the brass exposed again it dropped the temps a noticeable amount today. Yesterday was 85, today was 85, same drive, nothing different and my temps didn't really go above half which was nice.

What I think I want to do, however, is perhaps modify the stock cooler. Right now a carerra cooler setup is close to $1000. I figure why spend that on something that is just an expensive cooler, when I can modify the stock cooler to work better and more efficiently.

So realistically a good bit comes from airflow underneath the car, where the lines route. The rest is the trombone cooler in the fenderwell. So now that the brass is exposed again (not covered in mud/grime/crud/crap) it can do an efficient job again.

But I figured... the bumper DOES have a gap... what if I could fabricate some sort of small scoop in the bumper using the lip in the bumper?
Here's kind of a crappy mspaint example I am thinking of. I think with the turn signal removal and oil scoop addition scoop, and then a small scoop in the fender lip, it would help the original cooler a good bit.

Now... the reason I think this is a fun subject is because I know a lot of you guys deal with brass/aluminum/copper heatsinks on cpus, so a lot of you guys get cooling and how to cool things better. What would be a GOOD WAY to bring air INTO the cooler OR a good way to efficiently cool what is already there with simple modification?

Here's a pic from pelicanparts on what a trombone cooler looks like in the fenderwell (with the wheel removed so you can see)

What are the dimensions of that space? I have this crazy idea of replacing that trombone cooler with a heater core. :twisted:

The carrera cooler basically is just a small radiator type unit that replaces it. I've got a buddy who sells Porsche parts who has a used one he'll sell me for $200. But I'd like to improve on the setup that is there if at all possible before yanking everything out.

The other concern with pulling out what is there and putting in a new cooler that I haven't used before would also be oil flow, don't want to restrict the flow to the engine by any means, so it'd have to have a good flow.

Ok, so you were just thinking improving the airflow over what's already there?

If you put a scoop where you sketched it, then put a shroud along the bottom and up around behind the cooler with an exhaust up where the cooler hook-ups are, that would let you create the optimal airflow over the existing cooler.

Another thought for a sort of half-way step between the trombone cooler and a straight up radiator that would give you real high flow would be to get some flat copper tube (or even round tube) with the same inside cross-section area as the original cooler tube, then fold that over itself a lot, kinda like a radiator without the fins. It would also probably be a lot cheaper than $200.

Yeah I mean if I can keep my temps at least to 220F or below it would be nice for hot days. Anything 75F and under on a normal temp day is no biggie, but on days where it's in the 80s and 90s is when the temp starts climbing. Yesterday (before i cleaned off the cooler and the lines) it got up to 240F on the temp gauge which is borderline "Pull over and let me cool off!" temp.

the only solution here is to gather 1,000's of CPU heatsinks and epoxy them to your engine block.

Twigs, you crack me up man, love your posts.

Oil cooler scoop came in today! AWWWWW YEAHHHHH! I had to shave some material off to make it fit right, but it took maybe 10-15 minutes and a dremel to get it right. I like how it looks. It should be a nice substantial drop in temperatures too. Almost 90 degrees out today, so let's hope so!

thats actually pretty sweet.

now carbon fiber it yo.

It's tempting. I am thinking what I might do is try and redirect the air right onto the scoop, so I may keep the scoop the way it is, but use the leftover CF that I do have to make something to redirect air right onto the cooler. . Thing is, the horns are slightly in the way. That said it actually DID MAKE A DIFFERENCE! I am thinking since the wiring is very long, I can more than likely move the horns to the other side of the car.

I was a bit pessimistic because I thought "Well.. I AM using the stock cooler... it is not the best design and really.... how much difference could it make?" A LOT!

Today was one of the hottest days I've driven the car in, it was just a hair over 90 degrees F out. The last day I drove it to Bend, it reached close to half way just on the highway! Pretty nutso. On the highway at a normal speed today the darn thing stayed at about 220, and only once I was almost completely in town did it reach even halfway.

The only downside is, it is COMPLETELY USELESS once you get into traffic in town. For that, I am going to see if I can rig up a fan of some sort and see if I can figure out something else.

So far I have...

- Cleaned off trombone cooler to take crap off the brass, expose brass for better cooling
- Installed scoop

Successfully dropped my temps in REALLY HOT weather! That is a huge plus and will help engine life, so that makes me very happy.

Temps on the highway on a high 70s-mid 80ss day before I cleaned it, before the scoop.

Temps today with current scoop upgrade and cleaned up lines on a 90 degree day!

That scoop looks really clean!

well okay...I'll admit that is the first time i've ever seen a oil pressure gauge refered to as a "druck press"


You know you could rig a thermister,a relay and a clutch fan and mount that on the oil radiator so it'll kick on at stops or whenever its excessively hot?


With a thermister it'll automatically regulate the voltage to the fan based on how hot its getting (no electronics needed) Just thermal paste and epoxy it near the inlet for the radiator.

http://en.wikipedia.org/wiki/Thermistor



Oh man though, If that is a iron block, You ought to really..really..really...really flush and clean that radiator if you already haven't. Majorbud's Water radiator AND oil radiator were almost clogged with rust "mud" His water pump we are suspecting is clogged with that rust mud as well.

It was so bad, when he flushed the radiator for the first time, the water poured out jet black like ink, Then a deep brown. Finally a semi clear redish color and about 4 hours later after jamming the house in every hole of the radiator it ran clean.

the engine block is going to be disgusting i can already tell.

Druck = Pressure in german :P

The thermistor and fan idea is a good idea. Just need to find a suitable fan that will fit in there and do a decent job.

As to the flush... There is no radiator in this car, it is air-oil cooled by about 12 quarts of oil :P

The engine isn't all that dirty... I cleaned the entire thing up while it was out of the car.

Oh i was talking about the oil radiator, His had tons of "mud" in it as well. i know its air cooled :)


What size is the radiator? They make toooonns of 12v steel fans of all types.

looking on the internet i found this

"911 FENDER MOUNT OIL COOLER WITH ELECTRIC FAN"

but they want 1,200$ for that hahahhaha.


is that similar to yours? looks like two 120mm or 240mm fans would work. They just need to have a clutch so they can free-spin and not produce back feed.


[edit] now that i think about it, don't them old Datsuns have really small clutch fans?

Yeah $1200 is pretty psychotic for a small oil cooler and fan and 2 oil lines.

I'll have to see if I can poke around and find a solution that is cost effective. A guy on the pelicanparts forums offered me a carrera cooler with fan and lines for $450 which is a good deal, but i'm not sure I want to spend that much right now since all my extra money is going towards my track car project right now.. I'm not mr moneybags or richie rich. I get my cars at good prices and afford to drive them not because I'm made of money, but because I do all the maintenance myself which saves me a ton on labor and only costs me parts. I wish I could just drop $1200 at the word, that sure would be nice. :P If I save up I'm sure I'll find something.

I haven't been on here in quite a while. I haven't dropped off the face of the planet.

Not much changed on this project but I did end up doing a fabspeed system on it

you know its bad ass when you can hear each piston fire while its idiling.

Haha it sounds like it is going to take off and fly away! Awesome!
