Basically been right through the car.

Had a small amount of rust in the front of the chassis.

That was cutout and plated with the whole underneath of the car proofcoated before the car was complied and licensed.

All new suspension with Koni shocks and king springs.

Selby swaybars

Bigger turbo with front mount intercooler and Autronic computer.

Retrimmed interior with WRX seats

Heaps of other things that I've forgotten over the last 2 years :)

WOW, what a difference a tuner makes.

After the new turbo and autronic fitting dramas I was never that happy with the performance of the car.

Something was just not right but the tuner assured me it was as good as it could be.

It was running out of injectors and needed upgrading so that limited the power to 220rwhp.

The power was OK but the delivery was woefull.

Problem was that changing from first to second near the redline resulted in some lag until the revs built up again.

It was not really pleasant to drive that way and made it difficult to use in the tight circuit as per the above youtube video.

So the car has been sitting in my Son in laws workshop since June as I have no space left at home (too many toys).

We changed the injectors and returned the car to the same tuning workshop (the tuner had loked the Autronic so I had to go back (another story))

Anyway the well renowned tuner only worked contract for the workshop and is unreliable. He started working on the tune encountered a problem then dissappeared for weeks at a time.

i asked the workshop to get their new tuner to look at it instead of waiting so he went right through the car and found a number of problems that the other guy had overlooked. First off the turbo actuator was not operating correctly , there was an issue with the timing causing the missfire that the other tuner walked away from. To the new tuners credit he rang Autronic over east and sought some advise and fixed the problem the supposed Autronic expert tuner couldn't.

Anyway the results are amazing. Not only was there a power increase ,when changing into second this beast tries to shred the tyres :O:):D

This car is so torquey now by comparision. Felt like a new car when I drove it back to my Son in Laws workshop.

He will service the car and we'll do a few other jobs over the next 2 weeks until his new house is finished and the DR gets a permenant home at his place. I can then house the DR or GTR at his place so I can get to drive which one I feel like.

So to summarise

Tuner 1 =220rwhp

Tuner 2 =288rwhp :P

The tuner got the car to post 320rwhp but backed it off at my request as he recommends an actuator change to a lower psi rating to control the boost better.

The engine is stock internally

I've fitted a KKR380 turbo and PI-1 intercooler.

plus a Autronic SMC computer and keeping boost to 17psi.

The 288hp is just a number so not sure what you'll get on another dyno.

Main thing for me was going from 220 to 288hp on the same dyno

      Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in

      Let's just fix the problem by f**king the rest of the gearbox.

      Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
