Most definitely, sir.

I'd still try to find a way to support the header/turbo off the motor mount.

Colin- Would you consider doing an under-car turbo mount? The big plus of those is that your exhaust plumbing at the head is just like a N/A motor - use the stock manifold! I really wish I had found some time to look more closely at Compton's Ranger with the rear-mounted turbo at Carlisle. Talking to Planakis, they pretty much threw it together in an evening on a shoe-string budget, and then worked out the bugs over the next couple weeks. The toughest part was the oil pump, but apparently they finally found one up to the task after the first 3 or 4 failed.

I hate idea of under the car mount. What happens when you go through a puddle and your 1400 degree turbo gets cold water on it?

It gets wet and boils off?

Years ago, Nissan mounted a hood scoop on the 300ZX that pointed right at the turbo.

That said, you'd want to mount it in a somewhat protected area, and a splash shield wouldn't be a bad idea. On a non daily-driver, these type of things become less of a concern.

Is the volvo head a direct bolt on to the 2.3 block? And what kind of hp gains are there from the head alone? Does the DOHC flow alot better than the iron SOHC?

That was stupid

How was that stupid? Do you even know what it's going to do? I do. It will crack.

From what I'm told, even the stock Volvo head outflows the Esslinger head.

If metal is hot, and you throw water on it then it WILL crack. You wash your engine while it's cold... at least most of us would.

Alex, do you even understand simple physics?

Gentlemen...as you were.

Well most metal will not crack when its hot and water gets on it. But cast iron(witch are turbo housings,exhaust manifold are made out of) will crack if its real hot and suddenly gets cold. The reason behind this is the expantion rate of cast iron. When its near glowing and you get it real cold fast, the hot area stays expanded while the cold section is contracting rapidly. Cast iron dose not like to stretch. Plus when you make cast iron real hot and you dump water on it, you also make it get case harden. Witch makes it more prone to crack when its real thin.

Cast iron is real durable. But it has limitations.

Whoa, a month old topic ressurection!

What kind of EEC do you use with the Volvo head conversion? I heard you say you was going to maybe put the coil packs where the firewall was.
It really is looking good

Need a little scoop in the hood with the turbo compressor sticking out alittle, like on the NHRA Sport Compacts

How are you doing on your head Colin? Have not heard anything in a while. You still working on the header? Give us an update.
