Non Seq Porting??

How many of you guys have done the real non seq and didnt port there wastegate!! I have heard if you dont port it youll have boost spikes, but i want to know from someone who hasn't ported it!! The problem is that there is a big crack and i dont think any shop will be willing to take a shot at porting it!!

If thats the case, wouldnt it be worth your while just getting a new wastegate?

The wastegate is an integral part of the turbine housings. Do not go true non seq without porting the wategate, there is too much flow. I doubt you'd be able to stay under 16-17 psi.

i didn't do the full conversion, but my wastegate isn't ported and i never get boost spike, it holds constant til up top and then drops off maybe 1 or 2 psi at the very top

Actually, porting the wastegate is mainly for boost "creep", not spikes.

Check out this thread for some more info on the topics of boost spikes and creep:
