How strong are the n/a common blocks?

[Jack's Dodge]

we all at some point need to build up our blocks. Some have been honed which wears down the cylinder walls. I'd like my engine to have a fresh start. Just to run this by you guys, the internals are the only difference between the n/a nd turbo blocks. So the transition should be fairly straight foward. My idea is simply to get an n/a block, and have it rebuilt with t2 rods, t3 pistons, and all new berrings. Seems like a sound concept.

Are you thinking of going one of the later TBI blocks since they are cross drilled. If you do go the later TBI block it will the reinforcement between the back freeze plugs. You say that you are going to use T2 rods with T3 pistons? You know about how the valve relives won't match up and that you will have some hefty compression. If you already checked out this thread T3 pistons in a T1 block
and you are going to use the G-head with some chamber work and the TIII pistons have fun. I bet that would be a tough cheep engine.

N/A CB block is same as c/b turbo block.

That was an interesting read. T2 pistons are still doable, but I was looking for a cheap way to use forged. As long as the car is tuned, there won't be an issue. Still want a CB though.

i used a N/A common block this time, and i drilled a hole for the turbo oil drain back. that is the only difference in blocks.

check my post in the parts fs section.

Yes, theres a drain plug installed in the N/A's.

[MrBelvedere]

where do you drill for the oil return at on an na block

[turbovanman]

You drill the round pan under where the turbo should sit!
