It's $2400 drive in drive out (sorry about the cliche). And yes, everything that Nizpro sells is covered (except under ridiculous situations - scenarios whereby abuse will be obvious). I hope you understand what I mean. Greg Brindley.

Geez Mate I'm sorry to hear that! When the box was refitted did it shift as hard as the old box?? As you posted in another thread, I was also under the impression that the only stronger part available for these boxes was the kelvar band. Maybe some of these shops are having their own parts manufactured. Where is the trans serial number located? Cuspub, what is done to auto to make it handle 800nm (Not the specific details, just general info) ?? Mick Mick, you're right, I can't go into too many specifics. I say this becasue Nizpro in conjunction with its transmission partner, has spent lots of time on R&D (including various melt downs, slicing and dicing) to acheive a desired result. Bottom line is there are more than 100 changes - with solenoid pressures virtually untouched for the simple reason that this is not - from our research - where the problems stem from. The upgrade includes various unique manufactured parts, massive valve body mods, numerous heavy duty parts and of course a thorough rebuild (whether new or old). Hope this assists Mick. Greg Brindley.

Can't comment about the GT - whether the speed sensor may play havoc on the dyno as suggested - however having put various XR turbos through their paces on the dyno - including some 600 - 700 runs with our own cars (that's not taking into account the many hours on the engine dyno), we have never been a problem as described by Falcoon.

Great achievement Craig!

Nizpro has an upgrade they are happy to place behind their 800Nm Stage 3 kit.

I hate to say it, me being Nizpro's mouthpeace and all, but the APS exhaust would have to be the best looking, neatest mass produced system available in OZ. That said, lots of testing has suggested to us that the only real protagonist in the factory exhaust system is the catalytic converter. Replace this with a quality version - such as is supplied by APS - and as suggested by Vik351, you can achieve extremely good power levels without backpressure problems. Sometimes it's worth stepping back and sussing where it's best spending money. If performance is paramount, then spend your money on things that deliver power. If a nice note is everything, you know what to do. Greg Brindley.

I road tested an AU111 XR8 220 for a week culminating in a stack of laps at Winton Raceway. It all went well (apart from running out of brakes a couple of times on Winton's easy on brakes track) After virtually losing the pedal and suffering significant shake (as one does on the race track), over the day following Winton the brakes returned to normal with no shudder whatsoever. My 2 cents worth. Greg Brindley.

Da Hulk, as a matter of interest, were you having stalling problems prior to fitting the kit? It certainly seems to be a problem with some cars, but not others, and as far as Nizpro/Chiptorque has been able to decipher, it has something to do with the factory PCM. Testing will continue. Finding an appropriate clutch can be a problem, and I suspect that you are not the only one with that drama. As to the rough idle, I can guarantee you that we could get rid of that drama for you - if you were local it would simply be a case of dropping into a dealer or us, and we would fix it for free - of course. Great to hear that you concur with all others with the Stage 2 kit, it really does work well, and yep, on cold nights they can be a little scary. Excellent work, and if anything else comes up of interest, would love to hear from you. Greg Brindley.

Any more recent mods Brian?

Bcl and vik351, couldn't agree more. If you give your Turbo a hard time, I believe that the oil should in fact be changed at least every 5000k or even less. I attended the launch of the new Mobil 1 Syn, at which it was claimed that you could in fact run their oil in a turbo vehicle for 20,000 clicks. Which is all good and well, however IMHO and from the myriad of tests I have been involved with and published over the years (while taking into account that not every engine is tuned well hence the potential for fuel to wash down the bores and therefore deteriorate the viscosity), I would always recommend 5000k changes. Okay, if all a vehicle is used for is long country drives, yep, you could get away with fewer changes. Stop start driving, lots of cold starts intermingled with foot to the floor driving is definitely hard on any oil. Greg Brindley.

You may be surprised. We have had two with big power bend their rods. But hey, don't think it is merely the more powerful engines that can break rods, we have in fact seen a number of stock engine throw rods out the side. Greg Brindley

Congrats 100% from Nizpro. GB

Congrats 100%. Now with your 375-380 kW your theoretical 1/4 mile time is approximately an 11.47 @ 119mph. GB

Ezy10z. Thanks for your enquiry. Cobra simply hasn’t the financial resources of some others in the game; hence creating additional combinations takes a little longer than one would hope. That said, we are extremely keen to debut a new combination at the Heathcote meeting, but once again it is a time thing. The one thing I can say is that – assuming we make It to Heathcote – that everyone will need to have some eye socket glue at the ready. Other than this, we now have ‘Cobra Entry’, which is a Xede fitted and tuned for approximately 210-220 rwkW. There is also Stage Two Plus which via the addition of valve springs and a new front pipe/cat combination is now reaping a genuine 325 rwkW or 390 flywheel kW. But this is about as far as we want to go for the average streeter, as with approximately 780Nm and that much power, you really are looking the down the barrel at possible driveline upgrades. Going to bcl’s Stage 3 process that by adding even more mid range and top end, the driveline simply can’t cope. Hope this info helps. Greg Brindley. Nizpro.

All good comments folks, thanks. Appreciate your thoughts and also understand the subscription issue with Autospeed can be off-putting for some. As to Julian Edgar, I find it interesting that there are concerns out there about him. From my perspective, it's that he is prepared to write the truth that tends to upset some people. For example, in the back-to-back test he did with the Nizpro and APS cars, Nizpro's had a problem, and he (Julian) rightly pointed that out. Ezy10z, I have no interest in getting involved in any untoward arguments about who's kit does what, or slagging other products. It is a shame that a distributor of ours got a little carried away - however I have already addressed that issue, and besides, human nature being what it is, I can't tell somebody how to live their lives. Instead I will keep everything 'clean' and as previously stated let our customer cars do the talking for Nizpro (Cobra), just like bcl, turbo6 and others. Once again, thanks for the comments. Greg Brindley. Nizpro.

I find it interesting that quite often when a Nizpro product is mentioned, people clam up. Just like in this thread. Is it just me? Could somebody explain this phenomenon to me? I mean I wasn't aware of the article irrespective of the fact that I promote the product. Once I was told I of course had a look and noticed that this time around with a working ECU or whatever it was that proved to be the problem with an earlier Autospeed article, the highly critical Julian Edgar (critical but fair I should add) praised the product. And yet there has been no comment coming from this. This being the case, can anyone tell me where, what or why people don't post to threads such as this? Seriously, I would like to know from a marketing point of view. Greg Brindley. Nizpro.

Geea. Only on the Cobra Stage 3 kit do we touch the wastegate. To ensure better control and flow, we modify the wastegate 'pocket' and add a different actuator. That's about it. By combining this modification with the Stage 2, adding an upgraded cat, high flow fuel pump, more boost but of course (around 1.1 bar max) and upgrading the engine internally (blueprinting, rods), you can have as much as Bcl (between 350 and 370 rwkW - depending on the dyno). Greg Brindley. Nizpro.

Whether its the Stage 1 or Stage 2 Cobra kit, apart from the valve spring issue whereby Cobra (Nizpro) agrees that the catalytic converter can be a little restrictive (once heat kills it resulting in vastly higher back pressure hence valve spring dramas), all of the points addressed by Unigroup are answered. But of course, the way Cobra goes about things is different to APS, as we don't bother changing the stock fuel pump given a rating that is certainly capable of handling at least 370fwkw. And as you know we also retain the stock exhaust. In stark contrast to how Cobra retains the factory exhaust, there has and continues to be massive dissention regarding retaining this item with many suggesting it simply hasn't the flow capacity (hence back pressure) required to cope with say 13 psi and in Cobra's case, 290 rwkW. If this is the case, how is it that Turbo6 has run a 12.63 @ 113.6 mph with an untouched Cobra Stage 2 kit (no exhaust, no fuel pump upgrade)? Facing facts, as mentioned earlier, we acknowledge that the cat can be a problem, however until such time as it melts or falls apart (as they do after some time), we have no concerns with the factory exhaust. This said, by replacing the stock catalytic converter with a genuine high-flowing item we can increase rear wheel power output to approximately 305 (depending on the vehicle) and as such Cobra is now offering a replacement cat for this specific reason. But hey, until such time as the stock cat dies, we don't believe it's worth replacing. In other words, why spend more than you have to? Geea, I hope this helps. Noting of course that all of the issues mentioned earlier in the thread relate to systems that simply endeavour to improve on the inherently flawed factory induction system. Cobra, as you know, does away with the factory system all together. Greg Brindley. Nizpro.

Appreciate your thoughts guys. And no, I am not interested in the scuff plates because as 100% said, there's no way they'd fit my car. Now to the dash...here's one.
