Do you think its worth vs forced induction upgrade?

Price? Are you referring to the head or the intake manifold? I think you should pass on these and go forced induction. You will not reap the rewards of these parts on a stock motor. Just guessing since I didn't see prices, but I would expect the head to be around 2k and the intake above 1k. Forced induction might cost more (a lot more) but it will make a huge difference, these will only make a small difference

 

Not a chance in hell. A 10k built engine might make 275hp, a 10k turbo setup can make 700hp. NA power is 10 times more costly for little to know gains. Get FI for real power. If your a baller, get both. A built motor and a turbo together is Godlike.

 

Yes, it won’t compare to a 700 hp turbo build, but a 10k Endyn engine will make 360+ hp NA.

It’s been done, see thread below:

Agree. Not to mention FI is not for everyone. If a person just wants a little more power on a road course then NA is a way better route. More linear power delivery and better throttle response. If building a drag car go turbo. It's all in what your goals are.
