Engine Replacement

[SOLOR_ECLIPSE]

I am purchasing a 97 GST (5 speed) that has lost compression in 1 of the cilinders. This is the original stock motor from the factory in this car. Rather that having this engine rebuilt, would it be more efficiant for me to swap with a used motor? Can anyone tell me if this comes stock with the 7 bolt or 6 bolt? I know one is better than the other. Thanks!

Well, if it is indeed the factory motor still in the car, then your car is a 7bolt. As for being better, that's disputable. Most people (obviously) will tell you the 6 bolt is better because it is more reliable in the way that it is a lot less likely to get crank walk which will destroy the engine. As for the repair/ replace debate, that is up to you. The restrictions come down to the time/money available to you. If you are going to replace the motor, try and go with a 6 bolt. Of course, that's just IMO.

You need price things out and compare, with buying a used motor and just swapping it in your just gambling on when that motor will go out. A 6 bolt would be ideal but then again if your not trying to make over 400hp then a 7 bolt can be very reliable.

I appreciate the info! Looks like a 6 bolt will be what I am looking for then. Will a 1st gen 6 bolt drop right in w/o any major mods?

There is much info about 6 bolt swaps, you will need to search and read as much as possible before attempting it.

Neither of the motors are better than the other, they both got their ups and down, and as for crankwalk it is was overrated. It all depends on your money, and goals. As for swapping look here http://www.magnusmotorsports.com/tech/1gina2g.pdf
