I owned an '01 Jag S-Type 3.0 with only 88k miles that I bought to fix and flip. Two bad coils, radiator hose leaks at molded-in plastic tees, PCV hose disintegrated under the fuel rails in the middle of the vee, drive by wire (good luck with that), engine oil leaks already, bad fuel pump, bad window regulator, bad tie rod ends, fractured overflow bottle, fallen headliner, fractured center console, fractured dashboard components, and on and on.

The point is that the component quality sucked ass, especially rubber and plastic parts. It is a Ford engine and, if I recall, is also used in their minivans. It is not a narrow engine so I imagine packaging and exhaust will be compromised at best. The front sump is more fun requiring more fabrication.

I hope you enjoy it. It wouldn't have been my choice. I certainly wouldn't have picked an abused example to start with.

THis is the 3.0 liter version of the 2.5 v6 from the mazda6 (which shares no relation to the KLDE) right? A local built up the 3.0 liter version with a bunch of nobel parts and made some decent N/A power on an engine built for boost through some cracked up shitty ebay headers. I kind of cant wait till he gets money again because IIRC theres a PTE 6262 sitting at his house waiting on hotside parts to go in.

I was already planning if this engine has to many problems, then I was going to use it for moc up purposes until I pick up a new one. But yes it does not share any relationship to the KLDE. Like I said before, NA versions hit 400+ hp and boosted hit over 1000+.

The only thing Ford did is design the heads, Porsche designed the block and Cosworth did the crank, pistons and rods. In stock form the engine is not good on the outside, but it is strong. It might be wide but it does fit.

Here is the only one in the world that I have heard of that did this swap and to make it easy I'm not doing anything he did ;)

Just be sure to return that shit to the junk yard before the warranty expires.

That engine is a miracle, it somehow manufactures bearing grease. Pour your used motor oil into it, run it off a generator or windmill or hamster team and use the results to pack hubs and what not. I bet if you ran lightweight synthetic through it you would get a good gear oil.

Seems more like a Chrysler engine than a Ford/Porsche/Cosworth. Only MOPARs have the ability to create hydrocarbons and leak them in an endless organic cycle.

What EMS are you planning?

My engine looked like that. I said f-it cause I was rebuilding it anyway. Big mistake. For mockup sure, but Do not plan on using it for your actual 300 hp engine.

I have access to all sorts of fancy chemicals and cleaning equipment yet still some of that waxy sludge survived. If there's any oil galley that was blocked off after it was drilled as many are, then you are screwed.

Good luck though, it will be fun if you finish it!

I'll bet it got hot to make sludge like that.

I'm thinking of a mega squirt with a custom wiring harness.

I went through the engine and so far so good. Cylinder hone looks good along with the bearing surfaces even tho i'm changing all bearing, seals and gaskets. So yes as of right now I am keeping this engine. I will put up some picks soon.
