Help a Turbo newbie out
Well I'm getting ready to do a NA TII conversion and I barely understand the dark side.
The Jspec will have a 2.5 DP CS or RB dunno yet. a CS single cat back.
I will have the stock TID on until I fab one myself and use my Cold Air box I made.
I am buying a HKS FCD for back up but I understand I am going to get some pretty good boost creep.
If anyone has pics or a write up on porting the Waste gate on the stock S4 turbo that would be awesome.
I understand you can make the hole a little bigger than the flapper itself so it doesn't get stuck.
I've never opened up a turbo before so I need to know if there will be any gaskets I need to replace when I open up the exhaust side to port it.

Well I can't save up since I have to drive this daily driver and as soon as I get it running I have to go to work.
If I have an entire engine our of the car it would be easier to port and I don't want the engine creeping when I'm driving to work and blowing.

Porting out the s4 wastegate is both easy and fun. I have done a few and you just need some kind of rotary cutting tool, preferably a die grinder with a carbide burr. I haven't taken it past the flapper but just a little under. The only gaskets there are the gaskets from manifold to turbo and turbo to dp. Also, a good tip for removing the turbine housing is to just back out the two bolts that but up against the flanges a little at a time and it will push the housing off nice and easy. Good luck.

You shouldn't have to replace any gaskets, unless they are litteraly falling apart. The easiest way to port the waste gate is to buy a 3/4" drill bit from Home Depot. I should take about 60 sec to drill all of the way through
And with a 2.5" DP you should not have any creeping prolems with the stock turbo.

I had a stainless steel washer welded onto my stock flapper. I posted a couple of pics in this thread https://www.rx7club.com/forum/showth...hreadid=242089 . I have a full turbo back RB exhaust and I can hold 5 psi of boost.
