High compression pistons? You'll be lucky to hit 10psi before the motor blows apart. Stick to 8.8 early 5mge compression if you want to go turbo. 8-8.5 would be best if you wanna hit 20psi. 400 is doable, but not for 1500.

youre pesimistic, the pistons in a 5m suck, they gotta be replaced. I think I could hit 20psi with the right parts and equip... maybe 1500 is a little low, but I bet it shouldnt be too much more.

You'll spend close to that on fuel system alone to reliably put that kind of power down on a 5m. It can be done for less, but if you want reliable, its gonna cost ya. Add about 1000 for rods, 750 for pistons & rings, then you need a turbo capable of 20psi. ct26 won't do it. so now you need a manifold and turbo, throw in 1000-6000 (unless you get an adapter for the 7m manifold..then 700+), a decent IC 700+, plus bearings/gaskets ~350. And lots more $$$ for countless little things. It can get really expensive rather quickly. The only reason I see to build up a 5m to such high power levels is if you REALLY like the fact of using the original motor. However, if you look at cost vs gain, you are much better off doing a 7mgte swap. You can get 400bhp out of the stock engine with some decent boost/fuel mods. Sorry to burst your bubble, but the 5m is just not a good powerplant to get those kinda numbers for cheap. It's gonna cost $
