If you do the exhaust I first discribed with 1bar of boost ( 3 psi over stock, which is what you get if you pull the restrictor out ) and a good tune you should be around the 240-250rwkw range, so a gain of close to 100rwkw, if you are going to go that way do cam gears also, I have a few different settings for the cam gears on stock cams depending on what kind of power delivery your after

On 1 bar on a stock motor my 32 make 261rwkw

Doing the dump pipes on any GTR is a turbos off job, big job, and I would recommend at that point you install -9s while its apart with 600-1000cc injectors and make getting it tuned worth while

Have you pulled the restrictor yet ?

Yeah restrictor is off the car.

Haha now your geting too technical for me im only just learning haha... Ill just start off with a turbo back system and go on from there. Im not looking for big hp just a little more oomf! :D ill be happy with 20kw let alone 100! Haha thats sick.

How much gains (kw) did you achieve from your exhaust system?

Yes from full stock, IF, you do full exhaust with tune and cam gears and 1 bar boost

My car had 140rwkw @ 12psi ( stock boost ) when I first brought it and I now have 261rwkw @ 15psi and 293rwkw @ 19psi

Power mods on my car are

CES factory dump pipes and front pipe

MetalCat metallic cat convertor

HKS catback

I have pod filter with Z32 AFMs, but the stock box is fine at these levels

Cam gears

Boost controller

Apexi Power FC

I still have the stock ceramic turbos and untouched manifolds

Yeah 11.13 @ 123mph, I've had my 32 since 2002 and have done a few hundred passes plus a few hundred laps of various circuits, so I have learnt how to get the best out of that car

160rwkw for a stocker is very good, front pipes, cat and cat back plus a good tune should see you over 220, the dump pipes are a big job to change ( took me 10hrs go change turbos ) and best done when the motor is out or while changing turbos, I spun a big end at Wakefield and put the dumps on while changing the motor

I can replace the rear dump on my 32 with the turbo in place pretty easily now :D. Haven't touched the front turbo yet (thank Rajab for that).

You're making impressive numbers though. There's still hope for the ceramics!

I would NEVER push that much through stock ceramic turbos..... they will go pop

19 PSI through stock R32 Ceramics? FK that. I would run 15 PSI max. Recommend 14 psi to keep it "Safe". Even then they still go. I spat mine out my cat runing 8 PSI. Ticking time bomb.

Coming on 12 years now, I wear one set out ( bearings ) and am on the second set that have been in the car since 2008

I figured it was how you drive more then anything so I pick my moments and never hold them there long, ie no burnouts or trackdays on 19psi just drags and dyno runs

    • I swear at my GKTech ones every time I have to take them apart and replace a spherical. But I wouldn't swap them for anything else. They absolutely slay every other option, at least in terms of how they actually work. You sure you don't want to live with bearings? I mean, they don't have "ball bearings". They are rod ends and sphericals throughout. Tough as nuts, even though I have found more than one way to wear them out.
    • From when I was looking at getting the 86 engineered for the turbo, the joint said to put in a few euro 5 or 6 cats, then tune the car on a nice clean E85 tune When I was looking at a turbo for the MX5, it was basically the same thing, a couple of cats and a nice clean tune Although, it will depend on the year of the Jeep IRT emmisions standards required, and what mods are done, especially if it has a newer engine installed that requires a higher Euro
    • Yeah - but it's not actually that easy. There are limits for HC, CO, NOx and particulates. Particulates shouldn't be a concern in any petrol engine unless trying to comply to the very latest Euro standard. But getting a tune right so that all the others stay within limits AT THE SAME TIME is not a trivial exercise. You couldn't possibly get it right by just guessing at the tuner's dyno, unless he had a 4 gas analyser up the pipe, which is not often the case these days. It used to be. Every decent shop that did "tune ups" (as opposed to tuning) would have a 4 gas analsyer. Perhaps there's still quite a few of them around these days. But most "tuners" are only watching O2 and power readings.
    • Slight segway but the most expensive part of the whole thing which I would have thought would only be required for an engine size/type swap, not a VIV test, is emissions testing.  That's when you get into the big bucks.  I can't remember the exact price now but I got quotes for the GT-R based on swapping to RB30 (not that anyone bothers doing it legally anymore...) and it was around $4500 just for that alone.  The guy that does them manipulates the tune on the vehicle to make sure it passes.  The cheaper option is to book into Kangan Batman Tafe (I think that's where it was) and hire their tester.  Allegedly you're not allowed in there with the car though so not in a position to tweak anything to make sure the vehicle passes.  I'm sure in this day and age of ultra tuneable ECU's you could get the tuner to program a special efficiency (clean) tune that emits the lowest amount of particulates possible that would pass the test.  It might only make 50kW's but as long as it passed who cares!
    • I'm sure he has left signs, or, he is looking down, laughing That's my cunning plan for when I leave, lots of half finished projects, with no rhyme or reason of where I was actually up to, just to keep everyone on their toes
