Vipec is basically a Link and i have been running Links for years. Awesome ECU. Numerous motorsport options which are all unlocked, they only require a small cost motor sport harness be purchased, options of up to a 7 bar map sensor, runs well with the Ross Balancers crank trigger system I see no reason to not use one

Thats my problem, 11.006@136.5mph with a 2.0 60 footer. I think the best i have seen 60 wise was a high 1.7 lol I actually need more power off the line as 7500rpm bogs so hopefully the 2 step will sort it out. I could rev limit it but i dont like the sound of 9000rpm. I am guessing the tyres Marko is using would be the 255/50/16's i think they are, it whats most use on Nissan's. Its what i use.

Daniel used to race it all the time though and was pretty damned good on the launch. I reckon the ET Streets on a car with your power would almost be more of a hindrance than a help

A 2 step is a kind of launch control. Allows you to set a launch rpm as well as muck around with the tune to produce boost in neutral. It can be pretty brutal on both oil pumps and driveline though Throw a couple of washers between the nose of the diff and the cradle where the bolts are It makes quite a difference for tractions believe it or not. I find even launching ours with the ET STreets on i need about 7500rpm or it bogs down 11.1 with 320 in a 32 GTR is about right. A car i work on does it on a set of Bob Jane All Runders lol

Its still at Sydney Dragway. Your R33 has a Link G4 it in doesnt it? Get Yavuz to hook up the 2 step

Thanks Charlie. Its been a while but the car has the 2 step set up now so hopefully i can better my 2.0 60 foot times lol

So how many oil pumps can we count that have failed with a Ross balancer?

the only way you will know if everything was ok is to check it through a laptop. The dash gauges will noramlly look fine. I know for a fact that Yavuz is pretty tight on the safety side of things and doesnt leave much to chance. Do they still scrutineer cars these days? if they do, go through the left lane into the shed as it has a weigh bridge which they normally are happy for you to use. Just gotta make sure the car behind you doesnt follow you in Give us a yell next time you race it. We should be out next Friday night at the Full Throttle Friday. Hopefully we are asked not to come back until it has a roll cage and a parachute

I dont know how quickly the guy plans on upgrading the turbo, but a customs from Unigroup, also a member on here, is planning to upgrade his T04Z to a 6766. It sounds like he will be running the same turbo as ours only it will be a 26 versus a dirty 30 with a 25 head. Hopefully he does it some time soon so i will see if i can get a dyno graph of the 2 cars to compare the difference in power and torque

I will try and scan it up tonight. Mark used to always bring the car in to Advan for his work. I left there about 4.5 years ago and since then he has obviously switched workshops. Yavuz and his team know whats going on and he is a gun tuner Maybe he changed his mind on the 6766 after tuning our one. I know he has used the 6466 on a few cars and he has been happy with them. With your car being an RB30 i would think the 6766 would be a better option. Its slightly larger, but so is the RB30 Given the power levels its capable of its super responsive and provided you can screw the boost into your engine they will continue to make power well into the 30psi range Congrats on the times last night. The ET is awesome though the mph is a little low for the power level. How warm was it out there last night? I am wondering whether your ECU is picking something up and pulling some timing out to compensate for it, hence the lower mph. With 425rwkw I ran an 11.00 but it was at 136.5mph. The car constantly traps in the mid 130's. I would have expected your car to running quite similar mph. A mate had a problem like i am describing at Jambo a few years ago. Was driving it to the staging lanes and the engine was getting hot. The car had previously run an 11.3 so i put some cams in it to see if we could get it to run a 10, but it went backwards. Yavuz went for a drive with my mate and found the car was pulling timing out due to heat soak. We pushed it in the staging lanes and it straight away went 11.1 at 128mph What does it weigh? Do you know? It sounds like the track was really good last night. There was some decent cars out testing so it sounds like they prepped the track a bit better than normal for a Wednesday night

I didnt see torque to be honest. I also dont read a lot into dyno graphs as they are only a turning tool. It was just pretty easy to compare these two cars as its the same operator in very similar weather conditions I do know however that the car weighs in at 1440kg's with me in it and has run 137mph. That was with the old T78 so with an extra 55 odd rwkw i am sure its going to go 140mph plus fairly easily. Not bad for a car that gets driven to the track, put on some ET Streets and drive it home. I dont even take out the sub box

Thanks mate. Although its changed a lot i spent quite a bit of time working on your car back in the days when Mark took it to Advan, it was a neat car back then and i am sure its just as neat now Direct comparison is pretty easy here, same dynos, same operator We have a 6766, 1.0 split pulse exhaust housing on a Trust T88 manifold, high boost we made 485rwkw at 25psi 4400rpm, we make 19spi and 200rwkw, your making 20psi and about 260rwkw 4500rpm we are making about 20psi and about 225rwkw, yours is making 5000rpm we are making 25psi and about 360rwkw, your making 25psi and about 390rwkw but its when we get up into the revs that it makes a difference where yours pretty much flat lines at 5600 and 440ish rwkw and 25psi, ours continues to climb. At 6400rpm we have 450rwkw and it continues to make power through to the 485rwkw peak and 8500rpm redline. We used to rev it to about 9000rpm but i told Yavuz to back it off a little lol In all honesty its probably easier to get Yavuz to overlay the power curves on the dyno to gain a decent comparison The Precision turbos are an awesome thing. You will be pretty impressed i reckon.

We recently had our car tuned by Unigroup and made 485rwkw on 25psi and E-Flex. Didnt put any more boost into it due to stock head studs and the guys didnt want to risk lifting the head. The car is running a 6766 split pulse with a 1.0 rear end. It used to make 425rwkw with the old T78 at 25psi so we are very happy with the new turbo. Response is very similar which is the main thing Mark Robinsons old car You were picking your car up when we were dropping the S14 off from memory. Wil be nice with the 6466 on it though get Yavuz to overlay your graph with ours and see if the 6766 may be a better option You will make slightly more power with the 6766 with very very minimal difference in response

Ross upgraded our balancer when they designed the kit so i believe it should be a simple upgrade. It was a current balancer and was yet to be fitted to the engine though so dont know if this changes things I guess you would need to call Ross and ask if they are all able to be upgraded Piggaz, that really does show how reliable and rock solid it can be. It makes a big difference to timing values when your signals are a lot cleaner and makes it that much safer to make decent power

Mark doesnt even race the car at these events anymore does he?

Its all about how its built if you ask me. Put a high powered motor in a poorly setup car and its going to be slow. Put a lower powered engine in a well setup car and its likely to be faster. Yes, torque is great, but at the end of the day its not worth having if you cant use it. Perfect example is my old mate Frosty's Mazda 3. Extremely well setup track car with minimal engine mods. Most Eastern Creek track days he would get out in this car and play with the likes of E46 M3's and so forth. The only time they beat him was down the straight. As soon as turn one came up he was all over their ass again and ready to pass them at turn 2. All the torque in the world that the E46 made was not going to help them against this Mazda 3 because it used everything extremely well. Obviously it was part driver, but most people would not believe that a $150k M3 would be slower through the twisties than a $20k Mazda 3 If i was the OP, put the motor back in and sort the chassis out and suspension. Get it sorted and worry about the motor when it needs attention.

Try giving Maatouks Racing a call. I am sure Anthony will be able to sort it out for you. May very well have an intercooler kit sitting on the shelf for you to fit. As for damaging the engine/turbo whie testing it. A drive around the block with some light boost, even one reasonable load up, will be fine. Just make sure that it doesnt run much more than about 12psi as these turbo's dont like staying together at much past that

I can assure these things work, it was designed on our car by Unigroup Engineering and Ross. I will admit that we only run the bottom half as its a 26 in an S14 and the CAS Sensor Ross designed wont fit in our car as its simply too bulky We had around 500rpm worth of incorreect singnals in the upper rpm range and this fixed it straight away. It works a charm with the Link G4 that we run in the car.

If all you want to do is test the turbo just do a bodgy on it and join those two pipes together somehow

I have never understood how someone can actually think that running a fuel tank low on fuel will make the dirt suddenly lift off the bottom of the tank and float around lol

Easy as Above pic is the front of a turbo. The middle section is where your air cleaner needs to go. Either by way of an intake pipe or by directly bolting the air cleaner to the turbo. Being an RB25 in a VL it may have an air flow metre, if it does you will need to put that between the front of the turbo and the air cleaner The outlet of the turbo, that bit at the bottom left, is where your intercooler pipework starts. It should end at the throttle body. Somewhere between the outlet of the turbo and your throttle body is where your intercooler goes.

We went with the 6766 as the response is pretty much the same as the 6466 and it has the ability to make a bit more power. Its also made more power at lower boost which is always a good thing. Comparing it to the T78 we had on it its quite a bit more power for the same boost levels. The plan isnt to stay that way trust me. Next step is to get some head studs, an ethanol sensor and get it all sorted. Will put more boost in it and see where it goes. It ran 137mph on ET Street with about 420rwkw so see what it does with the new setup

Standard head studs and we dont want to lift the head. We are only using E-Flex without an ethanol sensor so had to leave some room for safety, and its only a street car I know many will say stock head studs should be fine but honestly, 485rwkw in an S14 is way more than enough for now. It leaves us some more power for when we get bored

unfortunately not. Yavuz and my girlfriend went through the previous dyno runs so i am not exactly sure why they couldnt find something that was comparable. It was also becoming quite time consuming as we have used Unigroup for years and there are loads of runs that have been done on their dyno over that time so we kind of gave up on looking It does drive a lot different and i am sure the drag strip will tell me its a different car.

Got the car tuned the other day at Unigroup and the Precision 6766 is a weapon of a turbo. We opted for the 1.0 T4 split pulse rear end. We used to have a good old T78 on the engine, its an RB26, and at the same boost the 6766 is about 55rwkw up. All we changed was the turbo and dump pipe We ended up with a consistant 485rwkw at 25psi on E-Flex which is currently showing around E60. Going to get some United E85 and see if we can crack 500rwkw with a bit more timing. I dont want to run any more boost so what it makes at 25psi is what its going to make
