So, I am coming up on the final purchase of my beater car. And the J2 will be going away for the winter to get some engine work done. I was debating on rebuilding the engine with a whole bunch of stuff. But had another oppurtunity come my way that I may take. I'll break down both and let you folks chime in from there.

The engine rebuild would cost me around 800-1200 dollars. This includes:
Shot-Peened Rods
Low Compression Pistons
New Gaskets
Headwork
Balance, Clean, Magnaflux Engine
Hone Cylinders

Mind you, this is on a engine that is coming up on 100,000 miles, along with the automatic transmission. The transmission would stay the same, and would hopefully take the abuse of 15+ psi driving.

My other option came to me from a friend over at RDTiburon, who can get me a Complete engine and manual transmission sway for around 1,100 dollars shipped to my door. The BetaII motor has been found to fit directly into the chassis of the J2/RD with little modification, and would use the old ECU and sensors I already have.

Option B seems like a better bet at this time, as the engine has around 30,000 miles on it, and would come with a manual transmission so I could run higher boost, and not have worry.

Now, there would be some modifications done to the BetaII engine if I chose that option. I would be installing a decompression plate, and installing a clutch and flywheel at a later date.

Thoughts and Comments are appreciated.

Thanks,
Sean

Do the 5spd swap...and later on down the road if you want to you can rebuild the new one.
The 5spd swap will make ur car so much more fun to drive. I used to have an automatic..I don't know how I could stand it.

If you rebuild your motor it's almost like having a new motor.
and low.comp pistons are much more reliable than a decomp. gasket.

I say rebuilt+manual swap
