So, after talking to a handful of different shops who have all worked closely with the FA20, I'm hearing some say that the FA20 can handle a max of about 330hp before internals start to go.

I'm sure everyone has their opinions and experiences, but what is the general consensus here?

There are three main things I'm being told by shops who have worked with and tuned these themselves:

* No more than 330 (one even said no more than 220)
* No forced induction / Only go N/A with IHE
* No E85 unless Stock

The shop consensus is that these motors are blowing because of too much heat in the cylinders... Pistons are warping, etc. A couple say this is because of the 12.5:1 compression.

So, the real question is... Unless you fully build the internals (which apparently can't handle any FI at all), what are the alternatives to making more than stock HP? (the shop that said 220 max said he replaces one FA20 a week)

Is a swap really the only alternative to completely building the internals?
