@asvpzane I haven't bought another turbo yet as the engine was damaged as well, engine is almost done now. I'm leaning towards the turbosmart 6262 turbo as it's slightly bigger then g30-770 and hopefully still similar in response. I'll fit in a speed sensor as well and update this section once it up and running.

Thankyou for that data it is all helpful and taken on board. How did you find the 6258 in drive ability and response aposed to the 5855 I did pressure test it once i fitted the pulsar turbo but it did have chinese cooler and std exhuast manifold with 3in exhuast very primitive low cost setup. On the street it was full boost 26pd at 4440rpm.

Rob Novak from definition motorsport, he been tuning my cars since 2004.

Differently genuine garrett this time around and will start looking into what tables I can build to monitor/control turbine speeds. The car runs a similar setup to your Komdotkom with two rotary switches one for power and one for traction control at 2% increases. 6-8% slip seems to be the fast as it just starts to slip but doesn't take too much power to control in the lower gears. I'm really impressed with the motec this far, step learning curve for me with ecu's but motec support has been very helpful with any questions or help.

It is GPR + paddle shift. Good point lithium, I noticed when using the traction control the boost would spike quickly during Cut events when looking at the data. Might be worth monitoring it against a speed sensor.

I2 Pro, I used it every time I take to circuit racing so a very basic understanding.

Im Slowly learning Lithium. At this stage I'm leaning towards replacing it with another g30 770 and fitting a speed sensor/possible a EMAP will its apart. Once it's back together I'll get some data and post it up. The ecu is fully unlocked so I will see if I can work it out.

Thankyou for doing that. A lot different to what I plotted but again I'm very new at this. Looks like there is still a bit of head room in that turbo, or am I looking at this incorrectly? It's running a motec m130 gprp.

Sorry should of mentioned that e85.

I did try to plot a turbo map of g30 770 using match bot but it was my first go at using it and I could be way out on this. It seemed to be out of the map by a large amount at 8500rpm with 26pd

Thanks for the detailed reply Lithium Okay first thing, I'll find some photos of the turbo failure. The night it failed we were at the drags and it was on the fourth pass of the night and it does have traction control which was on during the passes but only active in 1st and 2nd gear. The front wheel has made contact with the hosuing and snapped the shaft sending debris through the cooler and into the engine. One weird thing I did notice just before it failed was the intake temp in the airbox went higher then it ever has by 15 degrees (peaked 65c). Oil line is clean and seems to flow normal I checked that once the turbo was removed. The only reason I was going to go a bigger frame turbo was I was concerned it was overspeeding and failing again and I'm sure one day I'll want to turn it up some more. The g30 770 was great on the street and circuit, I will fit a speed sensor this time.

Hi Guys, Just wanting to replace my current turbo (pulsar g30-770)which has catastrophically failed, I believe it was from over-speeding but can't confirm that. The car S13 with rb25 neo with Tomei procams type b, rod bolts, metal headgasket, plasmaman plenum, standard exhuast manifold with external gate welded on and pulsar g30 770 .83 housing. Car made 591hp at the hubs on just over 26pd The purpose of the car is some street driving but does a lot of circuit racing and tarmac events. The car is great to drive super responsive on the street and track, as the engine is getting built as we speak and the turbo has failed I want to replace it with a garrett unit and a 6 boost manifold. Question is would a twin scroll g35-900 1.06 be as responsive? Or do I stay with a g30-770 and move up to a larger rear housing. Yes I know it's been covered in other sections but haven't found and real back to back information. Thanks Russell

Hey guys, Just after some advice on tyre pressures. I have ordered some nankang ar1 in 235/45/17 and 255/40/17 for my s13. Car weights 1320kg with me in it and most track work is at lakeside. Previously ran federal rsrr an they seemed happy around 37-39 psi but have seen robb_rb180 mention ar1 s like lower pressures around 28-29.

We test drove a heap of new cars such as the narava, amarok, ranger etc. We bought the trailblazer (wagon version of colorado). It has the mod cons, drives well, auto works well and its cheap to run its average fuel consumption is 8.8lts since we bought it. We tow a horse float with two horses which is 2700kg and it does it pretty good its a little done on power but most small capacity diesel are. Remember the new 4wds are not really designed for heavy terrian work, if you want to do that stuff look at patrols, landcruiser or old hulixs. As for the skyline put it in the garage and fix it later if you own it.

Well done!! Lookkng forward to seeing it out at the next roll racing night.

Yes that is a short nose crank in the photo I can second that. My neo was also a short nose crank. We fitted a crank collar why it was apart.

No they do everything from circuit cars to old school twin turbo v8s.

Definition motorsports mt gravatt Good honest people and have decades of experience

Being following your build for a while, such a great build. Seen you out at roll racing last night. It hooks up really well, you had some good races.

My setup is similar s13 with rb25 with just under 400hp, we orginally fitted a complete r33 rear end for the brakes and more strenght but the viscous lsd was still poor as the car does a lot of circuit work (not drifting) Recently fitted a 1.5 nismo pro diff and it completely changed the car for the better. For example before the 1.5 way it would spin in 2nd on accleration, now it has no wheel spin. The first track day it went 1.6 seconds faster a lap with no other changes. Do yourself a favour and buy a proper lsd

How was the day mike??

Hi guys, Is anyone doing the mid week sprint series this year at lakeside?? It is my first go at racing so would be great to meet a few members and learn some more about different setups. Ill be in a white s13 silvia come say hello.

Welcome to the forum. Nice to see another s13 rb25 neo. Looks really clean. Any more details??
