What do you guys thing the results are going to be like ? Is it worth while ? Porting and polishing the intake ( And also if it is advised doing the whole chop up of the various intake stages/chambers to make it one massive intake )

Thanks guys

- Not worth it since you need some engine management solution if you change engine internals so it becomes costly. 200hp JDM H22A/newer H22A4/8 could be "upgrade" if youre running older ones but Type S or H22A7 Typer R or aftermarket needs tuning to get the benefits.
- 70mm tb is too big.
- Also if youre doing work to intake manifold the effects might be negative if youre using stock ECU.
