This kit?

-20 cart is not a GTX

Good price then, GTX's are typically going for a few hundred more than their GT cousins

Edit, while i'm in the thread:

As another rb25/3071 owner who had a hell of a lot of trouble with boost control in a Garrett IW .63 housing i would strongly recommend a .82 with a GTX if you are staying internal gate.

I would probably still go a .63 if i was doing an external gate setup in either GT or GTX 3071

Did you try Street to Track? Thats where I ended up getting mine, he gets bloody good prices from Garrett Aus or ATP in the US.

I agree, run the .82 rear. I have the 1.06 and im very pleased with the way it comes on but the .82 is the pick.

Uncontrollable boost through the midrange and top end with the .63 housing

Enlarged the wastegate port and flap as much as possible to try and bypass more. It was partially successful in that it could now limit boost to 1.2bar through the midrange but would actually blow open up top. I concluded that the fairly large area of the flap and highish manifold prssure was simply able to apply too much force to the flap for the small actuator.

So next was going to be a big can actuator to replace the small garrett one but instead i crashed the car into the tyres at a race track...pretty confident that it would have done the job, but spending an extra 500 to mod the housing on a brand new turbo and buy a new actuator is a bit much.

Was going to upload a photo of the modded housing by photobucket is being a bitch

No i didnt try them scotty thought the price that i got was reasonable so i ran with it and unfortunately ive already the .63 rear housing so im just gunna roll with the punches and see how it all goes still waiting on delivery though

Just thought id post a pic up of my GTX3071 next to a size 14 nikes and my hairy leg lol

Hey Mick_o, what rear housing have you got? And can you please take and post a pic of that small plate with turbo part number?

And that doesn't look like big can WG actuator.

Nice shoes man, how much? :P

Now hurry up and get the turbo on the car and post results :)

Haha they were $220 mate i think and trust me im hangin to get it done not this weekend but the next me n jez are bolting her up and filling my tank up with e85! Yay!

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
