If I were you, i'd throw like 15psi or so into that thing... screw if it blows up, 1.8's are cheap

With a good aftermarket engine management, I would think the 1.8L could take about 12psi. With a good turbo, rrfpr, fuel pump, intercooler... about 7psi on pump gas.

You do realise that an EJ-25 Long block is likely cheaper, and just about as much power as a mild Turbo 1.8?

Then you can start from the much better EJ-25 base later when you go turbo.

Why not be unique?

Plus, the 1.8 might be capable of higher revs with its smaller displacement... If we could just get past this damn 6000 redline

Sure the 1.8L could rev higher, if you could get a valve train to take it. Even so a EJ20 or EJ22 should be good for atleast 10K on a off the shelf built bottom end. (stock block, regular production aftermarket pistons and rods).

Even the EJ-25 has a very short stroke compared to such high reving motors as the B18C5, so even the marginal R/S ratio doesn't both its ablity to rev.

the ej25 thing is a good point. Even with the boost, I'm only a little faster than a new Mustang GT. On the other hand, if you get a turbo kit now, you could drop a 2.2L turbo motor in later and have a kickass setup.
