930 Euro heat exchanger

[shanghai_todd]

I have decided to hold out with purchasing the turbo exhaust from my last post due to the fact that I want to be able to keep heat in the car, plus the final auction ended kinda high..

Looking at the stock heat exchangers for the 930 can someone tell me the difference between the Euro heat exchangers versus the US style ones? Any HP advantages?

Also for a 81 conversion will I need a different cross-over pipe, I read somewhere that it needs to be flat.

The US HE's are VERY restrictive. You will gain some HP just by going to the less restrictive Euro HE's and an aftermarket exhaust. They are not optimum, because the length of the exhaust path is still very long, but for anything under 400HP, they should be sufficient.

Nothing really beats proper headers, which have been optimized for more efficient exhaust flow to the turbo inlet.

If cost and heat is an issue, then yes, going to a Euro setup is a no brainer.

1986 - 1994 930s all used Euro style heat exchangers.
The US '78/9s are to be avoided.

Here is a picture of both. US top, Euro bottom.

BTW, here are some aftermarket SS headers with heater boxes, which you can get for $1200

Thanks guys, since I will be using my 3.0 I think boosting power over 400 HP is un-realistic Anything around 300 HP and I will be very happy, but like everyone says boost is like a drug. I know this from experience as I have already toy’d with my previous import cars to reach over 400 HP.

Seen a Euro exhaust for sale along with a complete 930 intake (Intake, Injectors, piping and Intercooler) and figured this might be a good start. This setup with a K27 might meet my immediate needs and I could always upgrade later on. With this setup what ignition recommendation would I need. I was thinking a MSD-6-BTW since I am running stock compression and want to avoid detonation

The swivel flanges are cool. I am surprised no one else thought of it. Any downsides?

The primaries are flame-ringed anyway (i.e: with an insert that slips into the ehxuast ports), so it's unlikely you'd get any exhaust gas leakage at the intersections. Swivel flanges are way cool! Looks like a good solution

this is what a euro system looks like installed on a 3.0 with the short bell housing

if you need the oil drip tank specific to the euro set-up, I've got one fs. the stock one will not work

BKreigsr-PM me with a price and also a picture if you have one. Also is the standard cross-over pipe suppose to have the dent in the middle? And does this have any effect for a 3.0 conversion?

[bkreigsr]

S-Todd here's some pics of my leftover parts. The kink in the above crossover (not mine) is to clear the clutch linkage on the short bellhousing trans. the size of your kink may vary. Imagine Auto offers a modified crossover that will clear, I think.

make me an offer for the drip tank. I was planning to unload all pieces at once but will separate if needed.
