Crank and Revs

[Typrus]

Q...
How much power is the factory crank good to?
How fast can you get a 5SFE to till with a good set of rods (Crowley comes to mind?) forged pistons, HP bearings, World Cams cams and a good balance job?
I was just looking at the cost of doing a decent performance build without a turbo or super.

With 11:1 compression and good internals... What would a 5SFE likely produce? Is the stock 95 ECU capable of keeping up or would I have to MegaSquirt it or something?

if you go through the trouble to change the compression and internals you would be cheating rourself if you didnt upgrade fuel system and ignition, all parts of a N/A upgrade.

i cant remember hearing of anyone who did an N/A build on a 5s but id say at the most you could squeez 225whp oiut of it...and thats a very generous guess with a total build. it would likly be closer to a stock V6 and at that point the cost to just swap a v6 would be cheaper.

Then comes the next Q.
1, 2, or 3 VZ?
Any here turbo or s/c'd any of them?

Power, revs, cost.. etc...

I'll do some forum searching when I get home (heading to work) but if someone could get me started it'd be awesome.


Also, whats the engine weight difference between the 5SFE and a given V-6? I know the 5SFE is Iron-blocked, aluminum head, but I'm not sure about the VZ's. I thought I had read somewhere that they were iron-sleeved aluminum.
