I have had a bit more of a think about it. MAKE SURE THE CLUTCH PLATES ARE AROUND THE RIGHT WAY INSIDE THE CLUTCH! It sounds obvious but our apprentice did this a while ago and thats what it turned out to be. This might help you out.

This is true for on/off/on throttle response. There is negligible difference when looking at dyno graphs at wide open throttle in terms of the boost line (unless the plenum has changed the result, not the piping).

I will try and post up some graphs but it might take a little while....I have a bit on and I am a retard with the scanner! At the end of the day, you need to choose a turbo that suits your goals. Don't pick one that people are raving about just because it is popular. Lets say for your build you might have a particular hp goal, or a full boost by XXXXrpm goal, so for your combination of parts that you are using, you need to pick a turbo that will perform how you want. EVERY PERSON IS DIFFERENT, so decide what is important to you and your goals, then work towards them. Hopefully you will get lots of advice from people like me, who do these modifications for a living. Our experience is your gain, so find a workshop that you feel comfortable with and give them as much information as you can and let them offer advice, examples of combinations they have done before and suggestions that can improve your setup. It will only aid your outcome. I guess the other thing you need to remember is BE REALISTIC with your goals. If you want 500hp, then go for it. If you want 300hp, then thats fine too. Don't get caught up in the ego dyno graph challenge. At the end of the day, YOU need to live with the car, so it has to please you. My job is to recommend solutions that are suitable for you. We build the car for YOU, YOUR DREAM, not for us. Its a big difference. We don't make millions of dollars in this industry, we do it more for the passion of it over just making money (trust me, I turned my back on a lucrative Engineering career to follow my passion of jap perf cars). So chances are, we love cars just as much as you, so we can talk about then non-stop, just like you.

There is a washer behind the pivot that can cause hassle with some twin plates. You might need to remove it to give the release bearing more room to engage/disengage. Second thing that springs to mind is the clutch pedal adjustment, see if you can move the pick up point that way. And I guess the other thing is make sure you don't have a leak in the clutch line itself, you did mention that you have done the slave and master, but perhaps you could be losing pressure through the line itself? It may not be the answer, but that might give you some more things to check out!!

Where abouts are you located buddy?

Gains vary from car to car as there are usually a bunch of things that can be improved to improve performance. If I was to quote a figure, I would say 10-20kw is possible, however the more power you are making, the more effective the upgrade becomes. I wouldn't personally run out and get one for a car with a standard turbo, but as part of a well put together package, the plazmaman stuff works really really well. We have a number of cars making big numbers with them. One is on a VC commodore that we are still developing that has a standard NEO RB25DET engine (plus a nitto dbs head gasket and arp studs) running a GT45R turbo on a 6Boost manifold and it is making 587hp @ wheels on 25psi (e85). The other is a RB25/30 with a GT4094R running 30psi on E85 making 633hp in a R32 GTST, which just ran a 10.4@135mph in full trim. Both of these cars use the plazmaman setup and both enjoy the response of the longer runners (yes the 45R is laggy, but we are fixing that with a ZEX nitrous spool kit!) Just another little note, the RB25/30 with the GT40R is more responsive than a standard RB25 with a GT3076R and makes heaps more power!!! Just goes to show that bigger doesn't have to be laggier!!

We are $495 for the pump, $12 gasket plus freight to wherever.

Another thing, make sure there isn't an autronic ecu or similar fitting up under the dash and wired in over the top of the standard ecu. Just because there is a standard ecu in the car, doesn't mean it is controlling the fuel and ignition side of things. I hate buying modified cars with unknown history. It makes issues like these much harder to deal with.

I make 940hp at the wheels on 37psi with an Autronic SM4, autronic CDI and splitfire coilpacks. How much more proven do you need?

Mercury Motorsport!! Sorry.....couldn't resist.

Unfortunately not (we generally go from standard straight to Hypertune (single throttle)), although I would expect there to not be a massive difference as the RB26 has short runners as standard so there isnt a dramatic difference like on the RB25. Actually, an interesting point, is that an RB25 with a GT35R on it will achieve full boost earlier than an RB26 with the same turbo kit, even though the RB25 has a smaller capacity. This is a combination of the VVTi and also the longer runners on the inlet manifold of the RB25. The RB26 will probably make more peak power and it also has more revs to work with.

The obvious area to investigate is the AVCR. I would suggest taking it to your local dyno and trying to run the car just on wastegate to see what it is doing, then tune the avcr on its low and high setting. Also, is it just recording a peak of 1.4bar or is it holding that throughout the rev range? Boost can be different in the higher gears, as it allows the engine to load up, which in turn works the turbo harder creating more boost on the same boost controller solenoid rate.

Hi Troy, I have this conversation with many customers and we have tested both back to back to determine the pros and cons. The main difference is that the Plazmaman retains the standard runners, where the Greddy has shorter runners incorperated into the unit. This design feature of the Greddy in simple terms, creates more top end power at the expense of mid range torque. The longer factory runners helps bring boost on at an earlier rpm (have seen 300-500rpm better spool!!!) so if you want your turbo to spool faster, make more useable mid range power/torque but miss out on a little bit of peak hp, then the Plazmaman is for you. If you only care about the number on the dyno, get the Greddy. I would sell 20 plazmaman plenums for every Greddy unit. NB: Do not buy a Greddy copy unless you have a guarantee from your supplier that is will not leak coolant. We had a number of customer supplied copies that were nothing but trouble and cost the customer heaps more by the time it was fitted. Hope this helps, if you have any questions feel free to PM me any time. Cheers, Trent Whyte MERCURY MOTORSPORT

AMEN!!

Would you let a stranger come to your house and pick up a $12k gearbox? I would be worried about being robbed, or having the place robbed in the not to distant future! People don't even list their address when selling a car for the exact same reason!

We (Mercury Motorsport) in no way condone not giving the money back and it is far from a scam! It is a large ticket item that 555kkk has for sale. People get nervous with this kind of cash and I have heard people being robbed for less. The only reason Mercury Motorsport is mentioned in this whole thing is because we are trying to help complete a sale that was between to other parties who obviously can't even sort themselves out. Well thats one way of paraphrasing my offer to help you get the gearbox in a hurry! I got a PM from gtr30beast asking for my assistance. I rang him and offered to mediate a solution that would help both parties (I was working under the assumption that Phillip still wanted the gearbox and that Ben still wanted to sell it). I didn't have to ring you and offer to help, but because I know Ben and that nothing sinister is going on I thought I could help out. I even offered to go and pick up the box and send it to Phillip to ensure that he had someone on his side up here (in Brisbane) to complete the sale for him! From what I can gather, BOTH parties are stressing about being ripped off (kind of ironic!), this has led to some very agro txting, each party doubting the other and then it was doomed from there. There is a peaceful solution and if that means I have to step in and help then that is what I am doing.

Have you paid entire 12k for the gearbox? Why would he send you a gearbox if you haven't paid for it? I have had many successful dealings with 555kkk and I am sure that he is not ripping you off. Sounds like there is more to this story than you are letting on!

I have an AVCR for sale.

I have a customer with a complete air conditioning setup out of an R33 which may fit. You can call him on 0401047460.

SOLD!

GOOD LUCK MARK!! Hope you reset the record, we will all be cheering for you.
