[Yellowb1rd]

Yan... being one who has actually gone through this conversion ('79 911SC) from beginning to end (not LS1 but carburated), I have to tell you that this is not an easy conversion, and the expenses pile on quickly. Be prepared to spend a good deal of money on the project, and even more prepared for the countless little items that you will need to purchase that continue to add up into seemingly infinatum.

I am as we speak having to remove the motor for the fourth time, and I'm putting a much more mild 350 into it, as the fire-breather (500 HP) was just too prone to overheating, and was incredibly unreliable. So much, that I seriously considered going back to the basics and yanking this thing out and putting the original 3.0 liter back in. It's been a lot of fun when it actually ran well, and the issues were sorted, but I never felt comfortable driving the car further than 50 miles from home. The power this car possessed is indescribable, but it's no good if you're constantly looking at the temp guage. These conversions are very prone to overheating [and many are hack jobs] so you've got to have the right engine and more importantly, a well-designed cooling system. I purchased everything from renegade to do this conversion (including radiator, and water pump), followed their instructions (which you can print out when you buy the kit) closely, and STILL had overheating issues. I believe that most of those issues stem from the motor, as I do not believe that it was rebuilt correctly. I'm hoping a more mild motor will change all that. Even with a relatively mild 350, you should see similar performance as the 930's of your era.

All my items were purchased from Renegade, including the rebuild of the 915 trans-axle ($4500). Your G50 is even stronger than my 915 (neither as strong as the 4-speed 930 trans), but if your trans-axle is tired, expect it to wear out more quickly than it ever would with the 3.2 liter. Remember, it's the low RPM torque that these 350's generate are what really put a strain on the stock Porsche trans-axles. I would recommend checking out Renegade's site for more information. Again, this is just not a conversion for the feint of heart.

If I could do it again, I probably would have stuck to the stock set up and turbo-charged the motor, but the entire process/project was a great learning experience, laced with frustration.

I can provide pics of the car in different stages, if you would like...
