looks like my PFC has landed in melbourne and should be in my hands tomorrow morning :thumbsup:

It will be fitted along with some cam gears and a high flow cat and put on the dyno for a mild power increase,

other mods on the car include:

Nizmo cooler

Pods

3" from the dumps back

running .9bar

my question is, seeing drop in cams can be had for around $650 a pair these days is it worth dropping some in and spending a little more time on the dyno while my car is still running stock bottom end, stock turbines manifolds and dumps?

cheers for any suggestions

I spose that stands to reason, my tuner tells me that with stock cams they make most improvements by dialing in the intake and the exaust is not so impressive but lowers the spool time..

how many more hours is dialing in some cams going to take?

oh, and if I take off my piping to get to the dumps I'm going to replace manifolds, turbines and dumps. so not willing to do dumps alone atm.

No point.

Stock turbos, dump etc. Better bang for buck changing those first.

Interestingly there is a little debate atm as to whether my car has stock ceramic turbines (and indeed stock dumps)

Of the 2 tuners I have used both have commented that my turbos are slow to spool and much louder than stock turbos, and both have suggested they are possibly steel wheel busshed bearing jobies or atleast possibly but until identified have only been running .9 bar, the car also has tuned length front pipe and altho obscured but all the crap in the way the dumps look fatter than standard, I'll have another look to see if I can tell if they are cast or not,

Is there an easy way to identify the turbos without ripping my engine apart?

the exaust side is on the cards but I was hoping to get some more thrills buy doing the easy stuff first..

      Yeah, that's when. I guess you could say I'm as patient as I am foolish(or just a masochist?🤔). I've strongly considered throwing in the towel and calling it all quits many times, and have almost done so. It's a first-world problem for sure, but I've had a pretty rough go of it, as well as other factors; hoping something good comes of all this; it has to. It definitely is half the price of the ATS and performs great, but I'd like to try something different for once. I've sampled the ATS in a friend's 32 and it's solid👍

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!
