I had no idea the jag engine weighed that much, but I'm not surprised because its a big ole hunk of aluminum. Its actually a fairly decent design and motorsports versions have done well, but the factory crippled the motor with an insane intake manifold that absolutely kills top end power and super soft valve springs to keep things quiet. Stiffer valve springs to allow it to rev and a nice short runner intake on it would probably yield some impressive power.

Check out Dindale's thread. He's going back and forth what to do about intake modding. Throw him some pointers he's all ears.

ITB setup or bust!

The Jag comment was more or less a joke... he loves that car and already promised his son he'd give it to him (the son is a young guy, married, IT at a tech company, I don't think he knows what to do with a car like that which has been sitting). Plus, the straight six is the engine you want in a E type IIRC. The earlier cars had them. The 70s ones had the V12 I think.

Y'all let me know when the ITB/MAF is happening...

Michael the microsquirt install is nearing its final phase, I've abandoned the idea to get the car running with stock sensors since it seems like it just isnt possible. I'll be converting to ford EDIS ignition and hopefully be up and running with the squirt in the next two weeks. ITB intake is built (in my head) so that will follow once I get the tune figured out. The nice thing is microsquirt supports staged injectors and the ability to control up to 12 injectors, so I'll probably use my 80# injectors as the primaries at low load, and then look into some other injectors to use as standoff injectors up by the butterflies under high load. Power output after all that is said and done will be the deciding factor to whether or not I install the big Holset, and I'm expecting some big numbers from the k27 with a great tune/intake/exhaust and lots of boost. I'm not ready to blow the 2.5 liter up yet.

I really want to do a maserati 4.7L v8 swap into my 968 eventually. Not sure it'll fit as the quad cams might be wide, but the maser engine bay is rather tight and it's packaged tight so it might just work. Rev range and shape of power curve is almost the same as the 968 motor, just shifted up. They don't sound bad either.

A 30000$ engine in a $9000 car is pushing it, isn't it? Cool idea and they sound good but... You REALLY have to like your 968 for that.

BikePilot

They are actually less expensive than a good clean LS6. Lots of wreaked maseratis and no one using them for swaps yet $6k buys a low mileage maser v8 with all the fixings. The maser v8 is based on the ferrari v8 but with timing chain rather than belt, more mild state of tune, and cross plane rather than flat plane crank. Pretty robust/durable motor.

The maser is also a transaxle car so that might help with bellhousing stuff.

But I do LOVE the 968!

Want there an S2 with LS400 v8 in it. That is a 32v V8. They make about 300 hp in stock trim. I would opt for the 4.3 liter version instead.

I designed the adapter for that. You have to mod pan and mod factory headers.

I'm thinking 3.5/3.7 ford duratec

These are 265-300hp in stock trim, way cheaper than an LS, and they almost have to be lighter. Ford and mazda have put them in a lot of cars with good reviews.

The 3.7 gets the 3500lb mustang to 60 in 5.3sec, traps over 100mph in the 1/4, and bests 30mpg. It should do very well in the much lighter 944.

Around have a way to get external dimensions?

I've got a 3.0 duratec in a ford fusion, I'll get dims tonight or tomorrow. It's a nice motor, but the 3.0 lacks the torque it really needs in a car as heavy as the fusion. I've driven a fusion S with the 3.5 liter and it does much better, plus the motor is basically bomb proof.

List of motors that would be good swaps for the 944:

1. Anything not built by Porsche

If you guys do the engine mount design, I'll make the adapters. I saw the 3.7 oil pan looks like it'll clear without chopping

BikePilot

The 3.7L duratec would be great I think. I could be interested in that conversion if something really bad ever happens to my stock motor. I don't think the performance increase would be enough to be worth the hassle. A supercharger would have my stocker cranking harder than the 3.7. I've had rental mustangs with that motor and found it quite good. Would be all the better in the lighter, lower-geared porsche.

The 3.0 is an entirely different motor from the 3.7 and 3.5 I think. The best 3.0 Duratec is the one found in the Jag S type I think. Much better flowing heads, more power. Would still be a step backward from the 968 motor. Jag heads may be a good mod for the fusion

An S2000 motor might be great in a light weight 924 conversion. Very durable, high-tech and revvy. I like them.

thirdgenbird

Yep, the 3.0 is an ok motor, but nothing like the 3.5. It's like comparing the lt1 to ls1

If it is a reasonably easy fit, I am very serious about the swap. Using the stock pan and manifolds would rock.
