944 engine weaknesses

You know how a pipe bomb works, right?
Well, when you're trying to contain pressure, you don't just need to shore up the weakest link, you need to shore up every link that isn't strong enough. Otherwise, what you have (very briefly) is an external combustion engine.

I know i came in late and i and repeating other guys but i say every thing about the block is bad. the bottom end internals are good the 8'v flows good for a 2v head the 16v flows heaps .
the 8v valve chain is a bit clunky . oiling is a big issue beyond 7000 rpm from most accounts
944 engines are a good thing up to 400whp beyond that many other things make sense .
but a 944 with more than 400whp needs heaps of chasis work
the 8v valve chain is a bit clunky . oiling is a big issue beyond 7000 rpm from most accounts

I think you also should ride in someones 500-600hp car. I have ridden in a late model corvette with a stroked 427 cubic inch LS series engine. Even with very large tires the car has severe traction issues. You should re anaylze your HP goals. If you want a dyno queen go buy and modify an old Integra or a Supra, make 1000hp and try not to get killed when it brakes traction at well over 100mph.....
Go drive in a bonafide high HP ride and I think you will re=evaluate your goals.

From the "Cool Chevy Ls1 video" thread, I wrote about the money numbers for LSx conversions:
.... I am hardly an expert... but I wish to take part in the conversation to help get to the bottom of this.
I spent around $1,700.00 for new big blacks, rotors, pads, adaptors and bias valve and getting it all installed.

Here is an easier solution and probably cheaper too.
Buy this LS1

It comes with everything you need to make it run. You get an LS1 and even a transmission that will hold up. Oh, yes, and they are even throwing in 4 free tires and wheels. Don't forget the corvette that comes with it....

Exactly. If you want a V8 with a real trans, buy the Vette. Modify it, and have fun. ZR1 coupes are in the mid 20's now. Plenty of mods available, and you will have something to sell.
I saw that Tony's 958 is up for sale for close to 40K. I don't know why he is selling his car, but he seems to like to build cars, sell them, and enjoy the aggravation all over again.
I thought this post was about the weakness of the 4 banger 951 engines?

Also, if you already have a 944 thats been built up except for the engine it seems like an easy choice to me. LS1 motors can be had for very cheap.

That is way to broad of a question.
#2 Rod Bearings (More common on mid year 2.5L)
Rod Failure
Piston Slap failure/Block damage (usually from piston slap) S2
Headstuds (more common on 3.0L blocks)
Headgaskets are more common on 2.5L engines
etc.. etc...
There is to many varibles because there is so much difference between different years and styles.

Depends on the motor and moddifications...
