Good thing I'm easy on it.
Belts are a normal wear and tear item that you expect to replace, especially on an LSx because chevy opts to put poor quality dayco belts on their motors from the factory. A quality serpentine belt will last you much longer than the dayco belts that the factory likes to provide you with. Belts going bad has nothing to do with the reliability of the motor. When was the last time you heard about the timing chain failing, or a siezed piston, rod thrown through the block, cracked block, rod bearings going bad due to oil starvation in cylinder x, etc etc?

It was a joke....... Meaning....... 55K miles, a dozen DE's, performance mods, daily driven, and all I've had to do is change the belt. I've got quite a bit of experience with the LS motors and they are very reliable.

Yeah, thank God.

Not that I would ever want to admit to it, but I think I speak for a few others here when I say I regret not starting with an LSX motor from the beginning. After all the engine pulls, rebuilds, breakdowns, mods, etc because of the 951 motor. It can be a long and expensive road. 350 to 400 whp is nothing to sneeze at. To make that power and be extremely reliable (road course reliable) is definitely something to respect. Not to mention instant torque. I wouldn't mind that.

Actually I think everyone is on the same page in here just the sarcasm meters are acting up.


IMO once the novelty of the turbo 4 wears off.... reality bites

and who says turbo and LSX are exclusive from one another

BTW why are you building a 3.0 Jeremy??

To be honest ??????????.......because I can and have nothing better to do. It would have been much cheaper to drop in a LS motor but anyone can do that.

I still want my p-car to have a p-motor. A 500 HP v-8 does little for me these days but a 500+ Hp 80's technology 4 cylinder makes me grin. The goal for the 951 is 500+ Hp, the goal for the chevy motor build (early parts collection phase) is 1,000.

The chevy gets a new motor and the LS-6 will eventually make its way into the spec car. That way everyone's happy......except the wife.

Yep. The LSx is the best explored option because it's the best option, which makes it the technical path of least resistance.

That makes it score low on "cool and interesting project", but high on "good results for minimal risk and effort".

you can get a turbo kit for the LS1 thats good for over 1000whp. you will blow up the engine after a little but it will still get it. were at 480whp @ 4lbs boost with this turbo kit on our GTO

It would be a nice comparison between a 500+hp i4 and 1000hp V8. For some reason I wonder about traction. Around the circuit it could be closer than you'd expect.

Mine will be a bit more involved then just dropping in a turbo kit. At this point of the parts collection phase it'll be a 8.5:1 402 CI TT based on a LS2 block and will probably still be cheaper then my 3.0L......maybe not. The wife thinks I'm nuts but she doesn't bitch about it too much.

Chris-

Just some friendly advice from a BTDT. Start with the nicest possible 944 series car you can find....period. When the swap is done, you will be obsessed with the car, and will deeply regret having started with a turd.

Find a conversion locally that you can drive or take a ride in. This will eliminate any hesitation you may have, and keep you motivated during the swap process. As far as resale, the LS motor will expand your potential buyer base tremendously. I can tell you from first hand experience, that the GM guys are enamored over this combination.

Reliability?? My swap has been my commuter AND weekend weapon for the last two years and I've never been late to work, and the only money I spend is on mods.
