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.
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 $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.
If you dont have the mechanical skills to do an engine swap then you probably dont have the skills to build a 15psi system from scratch. It would be more complex than a straight engine swap. Especially considering how many resources there are to help with the 7m swap.CST said:I don't have the mechanical skills for doing an engine swap on my own, so it would seem a lot more cost efficent to just keep the 5m.
20psi... yeah, thats wishful, lol... think I could get to 15 for about 4k? The body is in good shape and the transmission is fairly new (about 30k miles)
Chances are he gonna strap on a 150 shot of n20 onto it, and call it "Safe".CST said:Okay, I just got off the phone with a mechanic... he was sayin that I could get a safe 350bhp 5mge for around 2500, is he talking crap or what? Cuz from what you all say it sounds like it but I dunno, he knows more about cars than I do.
