Details of the parts required for the 3.4 -> 3.8 swap would be good.

Are all the engine mounts in teh same place?

Are all the engine/ electric sensors in the same place?

Could you run the 3.4 inlet manifold and throttle (to avoid going to eGas if you have an early car) with a remapped 3.4 ECU?

Instead of getting the whole engine, could you just swap the bottom end and run 3.4 heads and induction (remapped) which may make the swap easier/ cheaper. Or, would that not work? I assume head bolt pattern etc are the same and all the oil/ waterways but I am thinking that the cams *may* be driven differently etc.

If you could just swap the bottom end out (even just buy a crank and rods) then it may cut the cost down significantly, especially when using new parts, particularly if you could build your own engine at the same time. Maybe upgrade with Nickies liners while you have it apart.

Anyway, lots of thoughts in my head for power/ capacity, reliably but on the cheap! LOL!

 

my car is at roock now for a 3.6 upgrade

 

Hey wey..... why a 3.6 and not a 3.8? and how much is it running you? i want to do the same....... thanks

 

Fabian had a 3.6 come in with a bad IMS that he will rebuild for me. porsche replaced the motor in the other car. i looked at the 3.8 but it was around $9k more than what i'll spend, and likely would require beefed up components. i suggest you call him or Jake Raby for upgrade pricing.

 

Just an update: Talked with Renegade. The Ls7 will fit the 996 but is still a few years away to work out the details. I'm waiting!! I plan on visiting their shop in Vegas in the near future and will get more info and might try to twist an arm or two to have them get on it sooner.

 

Then you'll own a chevy.I'm not going to flame you but why? Why not just buy a Corvette or save your pennies and get a GT?

 

3.8 all the way!!!!

 

I think it is an interesting concept. Porsche handling with Corvette muscle and price point. Not sure I would go this route but I would love to see it done as a potential option to a blown engine. My biggest concern would be the potential difference in engine weight distribution and the resulting effect on handling.

 

None.. The vette motor is actually lighter.

 

An engine swap is an engine swap - I'd rather put something back in there that is more reliable, is lighter, has almost double the horsepower and allows me otherwise to keep my Porsche. Call it what ever you want, but I might not be able to hear you since I'll be so far ahead.

 

Now that make it even more interesting.

 

How about a Mazda rotary turbo engine?

 

What about it? Is it capable of making 550 to 700 hp? Is someone else resolving the electrical connection issues? Have other people already installed it with proven results? Is it reliable and easily serviced? Will it fit? How much does it weigh? What's the cost? If you get favorable answers to all these questions, then go for it.

I think each individual has to do their own cost v benefit analysis. Like others have stated above, they would never put anything but a Porsche engine in their cars. That's fine. Some would rather spend $10k or so on a supercharger. I would rather get an entire engine built from the ground up made for a higher level of performance for less money than a supercharger, when, if at all, my engine blows.

 

Putting a rotary would have benefits and draw backs. The only benefit I see is that the engine is pushed closer to the center of the car. Even though it is a 1.3ltr engine, it is a bit heavier than the LS1. It is smaller though reason why engine placement is closer to the wheels and it might sit lower.

Now my main concern would be cooling. Rotaries run hotter than you piston engines so cooling would be an area of attention. Second the lack of torque unless you go with a small turbo but this will limit you to about 350-375 whp. Then the sound of a rotary in a Porsche would be weird.

Then there comes the inevitable question of engine rebuilding. It isn't a question of "is it going to need it?", more like "when will it needs it?". So you really are not moving in the right directing if you replace the flat 6 with a rotary. Even though the rotary cost $2500 to replace.
