turbo 2.3
i wrecked my 91 5.0 so i bought another 4 cyl. body to transplant and drive while i biuld my motor again. the 2.3 is so slow and i got a turbo manifold and turbo yesturday so how much boost can i run on a stock 2.3 and what are the specs on the motor.

The stock turbo motors had forged pistons with 8.5:1 compression ratio while your N/A motor has cast pistons with 9:1 ratio. Rods and crank are the same
The turbo block is basically the same except for the oil return fitting for the turbo on the right side of the block (a bit of trivia, all 2.3's had the boss for the oil return, as the blocks were coming down the assembly line, they were weighed. The heaviest blocks were set aside to have the oil return drilled. Ford's theory being the heavier blocks were stronger). You could either drill and tap your block for the oil return or drill and weld the pan.
What year is your 2.3 car? If its 91 or newer, it will have the DIS (Distributorless Ignition System) which isn't as flexible as the older distributor style.
Either way you'll need the computer, vane meter (like a mass air meter) and injectors from a turbo car. You may be OK for low boost with the stock injectors and pump, but the timing curve will be all wrong for the turbo setup.
Basically I'm politely telling you to save your time and money for the 5.0. I wouldn't recommend trying to turbo a N/A daily driver as it won't be worth it in the long run.

way to let em down easy Dave 
.... But i would like to know how much a stock bottem end Merkur block can handle... I have a cam, good valve train n such... I currently have it turned up to 15lbs... on pump gas.. whats the limit you think?

BTW, does your brother still have that other XR4Ti for sale?

I've been running 23-24 lbs on pump gas with the cold weather. It usually runs about 22 during the heat. Of course I have full control over my timing and fuel and I'm not sure how different it is from the stock EEC. But many people are running low 20's with stock electronics on pump gas.

I have to say that the pistons are not the same...... obviously the difference in compression is due to the pistons, and the Turbo motors had Forged pistons....

The compression is 8.0:1 for the factory turbo forged pistons. And I don't think ALL of the 2.3 blocks have the undrilled boss, just some of the non-turbo ones.
And I don't think you'd need all that other stuff to turbocharge a 2.3, although that IS how the turbo cars came *from the factory*. The pistons are pretty essential, but the other stuff can be used in one way or another. For example, a lot of V8 guys will use their stock stuff when they put turbos on, and you should be able to as well. There's no reason an FMU can't work on a 2.3, you know.

you could do it with just an fmu or something of that nature,but the pistons and the valves WILL NOT hold up under any kind of boost,the non turbo motors don't have hardened valve seats and the stock cast pistons do not hold up well either.
also,if it is a dis setup there is no way to retard the timing for the turbo,don't retard timing and you will get detonation.
The 5.0 mustangs can get away with it because they have forged pistons and hardened valve seats factory,and you can retard the timing
hope this helps
