T2 Swap

[kain]

What is the S5 capable of?

the block? the rear iron doesnt crack. people make 800 wheel hp in those, but thats with new studs and other mods to reinforce it. the s4 iron cracks in a certain spot as the engine wants to twist, it cracks. not bad, but still, enough to piss you off and have to remove the iron. still... 450 or 500 wheel hp till it cracks is pretty safe for daily driving.

the harness is chewed? remove the NA harness and see how much of the actual chassis and other harnesses are actually chewed.if the chasis harness is chewed, then that can be rebuilt and not worried about.

the difference between s4 and s5 t2 engines is a lot. the s4 has lower compression rotors, crap turbo and crap waste gate, and the intake is on the small side. not to mention the s4 rear iron. also, the spark plug locations on the s4 vs the s5 rotor housings are slightly different. s5 is basically the better engine hands down. turbo is better (compressor wheel is better with a better waste gate in the turbine housing ), rotors are higher compression, the iron doesn't crack, and the intake manifold has huge ports.

as i have suggested many times over and over, just ditch the stock electronics man. new wiring harness with new clips is SO nice to have. especially when they dont break when the wind blows wrong.

Wow, you are very knowledgeable, and I appreciate the help and the advice. The S5 engine will come with a new harness, so that might be the safe bet. It sounds like the S5 might be the way to go, especially if I have future plans to add more power to the car. I am grabbing the car from my mom's the weekend of the 13th, next month. That being said. As soon as it get's here, I will try to find an engine hoist to use, or buy, pull the engine and see how bad the damage is to the rest of the harnesses. I also have to pull all carpeting out of the car too for either cleaning or replacement, so it might be pretty easy for me to re-route a new harness anyway. As I said before I might ask you to come by to get your input.
