TurboCharged 2.5
OK I have my engine completely in pieces and finished inspecting all the bottom end components and now I'm suddenly thinking of turbocharging. I have to replace my pistons anyway so what I was thinking was to lower the compression to around 7.5:1, keep the existing rods, bigger valves, same cams (any ideas???), Bigger injectors, I currently have two mitsu turbos, megasquirt. Just wanted to get an idea from everyone what they think before I go in face first. Thanks Alfisti.

My goal for the car is 300 Hp and budget is around 2K if I choose to go down this route. I have been looking for a 24v 164 engine but have had no luck. I figured since I already have 2 turbos and am in the midst of building a megasquirt, that a setup is not going to be that bad but since I have never done it before it sounds like a challege. Please post the manual enzo I would love to see it. Thanks all.
I think that is not adequate for 300bhp with good power curve.
I haven't turbocharged anything before but from what I've read, to get the most power per lb of boost, you need to spend a lot of time building a good exhaust manifold (the details like, length, collector shape, etc are important), cams to match, intercooling, fuel and ignition mapping. You have MS, but you still need a better way to control spark advance besides the stock BOSCH ignition module.
The pistons alone may cost you $800. My J&E pistons cost $890 after discount (with rings, pins, clips etc).
I think with a log manifold and basic intercooling and if you just turn the dissy (retarding), 225 bhp should be achievable. I could be wrong though.
