Punctuation is your friend :domokun:

If you are only aiming for 260 at the rears then just go out and buy a second hand motor. Stock internals will handle that power.

But obviously you will need all the supporting mods:

Power FC(or similar)

555cc injectors(or similar)

Bigger fuel pump

Intercooler

Highflowed turbo (or similar aftermarket turbo)

That will all come to about 5-6k (excluding labour)

pistons - $1400

rods (GTR) $150 (i forget ARP rod bolt prices, maybe $150 also)

Depending on what else is busted, like how bad the failure was etc will depend on other costs (like if the crank is stuffed and needs replacing)

Also depends what you want done at the same time like oil restrictors, what bearings you choose, head tidy up, head gasket etc etc -

You'd also do the turbo at the same time so manifold gaskets, new manifold studs (almost a required item IMO) and any other hoses that might be perishing etc etc

So could be as much as another 3-5k. Then $1k - 1.2k for motor in/out and so on, its really something thats hard to tell

I wouldnt use a hypergear turbo on a built motor though, its like building a drag car and putting 225 street tyres on it, does the motor no justice.

Put a nice GT3076 on it or something with some great midrange and top end.
