Porsche Killer Build

Jayhovah

Seems like a lot of reports of the old GTM manifolds cracking.
You could probably move to the new GTM/Gamma manifolds / o2 housings. They flow significantly better (according to GTM) and are easier to install (compared to what I saw in the install manual for the older style kits).

One thing to note though... the flange positions from the o2 housings seem a little off to me. I can't confirm this because I also installed cheap ebay test pipes at the same time and my exhaust didn't fit quite right. I don't know for sure if it is the gamma o2 housings or the test pipes (or both) that are causing the issue for me... but I do know that GrooveStyle has Z1 test pipes (and the same Gamma V3 kit) and his exhaust also didn't fit quite right.

edit: I have some old GTM test pipes waiting to go in to see if the fit improves. If not, I will just have a custom exhaust shop cut/modify them to fit properly. Should be a relatively inexpensive job.

Not trying to troll you but... why call it a Porsche killer build? Sounds like you are trying to build a dragster to race a car that is in a completely different class. Porsches are known for handling, not speed. Hell, even as a 911 owner, I see those videos of the 1200hp 911 Turbo builds and can't figure out how they are still so damn slow! lol. Go find a Hellcat to beat up on.

Anyhow, good luck with your build and stay safe.

Chiming in with my 2 cents...I always wanted a P car GT3, but entry cost alone is quite prohibitive. So, I always dream of my car out sharp, our corner, out brake , out last a stock 996 GT3. Close enough HP, a fair target to reach with some bolt-on's. But I know, at the end of the day, engine won't sound the same, feel won't be the same, forward visibility won't be the same, etc.

So in some ways, I kinda know where squid is coming from, but I also understand what tigger is saying. it will always be Apple vs Orange, won't ever be the same.

Best of luck with the build

Both great points! I hear that the Z is a poor man's Porsche, alot. I was just poking back. Nothing too serious,
