I would just really hate if I spend over $1000 on an Sti Vf turbo, Sti tmic, injectors, fuel pump etc, flash the stage 3 map and blow my ej205 within a year.

That's going to be your problem.. it doesn't matter what shortblock you use, if you have a crap tune on the car it's only going to be a matter of time. Replacing a stock block with another stock block isn't going to make your engine any stronger. There's no reason to build the engine for a VF turbo.. in fact, I expect you will a lot more likely to have engine troubles if you change things out, rather than leaving it how it is. There's really no point to what you're wanting to do, the ej207 short block won't be any stronger, and you're introducing a lot of new things to go wrong.

You're going to have a hard time finding someone running that combo, because there's no point to doing it.



IF you really want a block that "can hold way more power than I have".. then you need to build the engine (forged rods/pistons/etc). Of course you should realize that built engines last significantly shorter than OEM engines. You can build your block to handle 600whp, but it's not going to last more than 30k-50k miles (at most).

To reiterate, the more power you build your engine to handle, the less reliable it will be. If you're worried about reliability, first thing you need to do is stay away from ****ty OTS maps and get a real tune.
