My result

Almost identical to mine, except you made 7-8hp more with 3psi less boost

I made 318rwhp (237 odd rwkw) on 20psi. On a dyno dynamics too.

Did the tuner do any runs on 20psi?

Is it the internal gate? if so which actuator did you get? Cheers.

This might be off skyline topics but any one know any good ecus or perferred plugin ecus or flash software that I can run with a VW Golf GTI 2L turbo DSG motor? Got a offer to develop bigger bolton turbo for that car but its totally new to me. cheers.

Bluefin. Similar to the cobb port on R35s

Gold Coast.

I thought yours was making 300rwkw but was just lazy without VCT or something?

I made 392.8rwhp on a hub dyno with correction enabled. On a Dyno Dynamics roller dyno I made 318rwhp@18psi, so very similar to you and Luke.

Looks fairly consistent with all the other results from the turbo (that are not a Hypergear test result)

Yes, unfortunately it's looking that way...

I always thought that the ATR43 G3 was suposed to be good for around the 280+rwkw mark on 20psi for r33/r34 running PULP?

Kasko, let me know how you go with you're turbo install!

Edited by Mitcho_7

The new FNT version should be more than that too, around 300rwkw. Stao made 320rwkw@20psi.

Will see how my car goes when it gets retuned without the ECU errors sometime this month, after the Plazmaman, HKS fuel rail, and ID1000's go on. Hopefully getting that done this weekend so will see where things are at next week, hopefully a retune will be sooner rather than later.

Am I the only one who saw that boost maxed at 17psi and bled off to 15psi? Definitely something there, holding you back...look how fast power climbs up and dies in the ass as the boost bleeds off.

Have my car booked in with Racepace on Monday/Tuesday...I look forward to bringing you all the results of my experimental, SS1PU high flow :D

I noticed that aswell.. Goodluck with the experiment!

Its pretty hard to sort as every car is pretty unique in its own way of modification.

The turbocharger it self is exactly the same as they all milled through the same machine to the same specifications on the same programe. Reason for diversity in power level that ranges from 320rwkws to 201rwkws can only depend other supporting mods, engine condition and the tune.

I found most consumers whom purchases Bolton turbos are likely to purchase bolton street legal or cop friendly parts, then modify their cars that way, such setup will not produce power. Plus some tuners not been able to tune for its best, per back to back result comparison from tunning shown in previous pages.

The G3 in similar setup as test car on factory engine produces around 280~300rwkws at 19~20psi as norm and there are plenty of people getting that. For people whom resulted below average, compare your car's mods based on:

Intake <== Same diameter as inlet of turbo

Exhaust <== Bell mouth minimum3 inch turbo back straight through

Intercooler <== No return flows (specially CN return flows), Use quality 600x300x75mm core.

Engine <== Even compression within OEM Specifications, Correct initial timing.

Tune

To the test car and this thread has plenty of information on caused affects from various parts.

Obviously people don't post unless they need assistance. The problem solving information are very helpful for other modifiers.

Need high pressure actuator to hold boost straight. This is result of swaping for a soft 14psi actuator, the effects were has been told before the downgrade.

My car has had the intake side sorted out with proper 3 inch to the pod. I'm going back to get it tuned soon. My compression is good (155), exhaust is good (will do a dropped exhaust run), my intercooler is a nice big genuine hybrid cooler. Fingers crossed.

I run the PU high flow, its just a G3 with factory comp housing and that pulled 287rwkws on 19psi. Simon I remember you were pulling 260rwkws with same turbo on a RB20det? I'm sure it can make the power, just need to sort out every thing else, Stao's already advised parts to get and what not to get.

I spoke at length with Tao about this after collecting the car and he believes that the intercooler is the main thing holding power back.

I specifically asked my tuner if this was the cause and he doesn't think so. In fact he seemed pretty certain that this was around the best result that I could get with 98 fuel on this setup, despite me raising these other G3 results on the forums. I haven't got any inlet temp readings so can't confirm either way.

What he did say is he had to spend the better part of 8 hours tuning, because initially the timing was normal, but after 2/3rds the way through the power run the car would ping, so he removed two degrees of timing & added fuel at that part. Then run again and the car would ping at a different point in the rev range. Remove timing etc again. Then because the timing was so retarded the coils were being put under much more strain be trying to fire at a much closer highest point of pressure ATDC, making the car was misfire. He then re-gapped the plugs and try again. Then up the boost and start seeing ping/misfire all over again. The car did not sound as though it was particularly easy to tune, but I don't know how hard or easy other G3 equipped cars have been to tune.

My tuner's opinion is that I can reach 300kw probably, but only with e85 being that it is much more resistant to knock, and he feels that the way the car responded with the amount of timing he was adding and removing, the car can take another 6 degrees of timing at least with e85.

I was aware of the fact that the softer actuator would bleed a bit up top, and I'm fine with that, most of the results I've seen have been doing that if they're under 20 psi.

I do not want to run over 20 psi, and I instructed the shop that I had chosen 18psi as my target. So when the turbo was being run up on the dyno 1st time they noticed the boost still climbing at 23 they stopped and took it off and called me to confirm. They bench tested it and found it started to move at 29 psi which Stao tells me is the required spring pressure to get around having any dip at high rpm in boost, however since the tuner directly saw it still climbing at 22-23 I told them not to use this because it was too far above my target (daily driver).

I then organised with Stao to have him send a 14psi actuator which I originally wanted and his new rear housing flange plate design which I thought could go on at the same time. Unfortunately the actuator assembly arrived was sent in 2 parts, the actuator itself sent first, and the flange plate and gold thread that the actuator rod screws into sent second. Since my car was going on 4 weeks in the shop they had to get it finished & couldn't wait for the 2nd part to arrive, so they bolted up a 14psi actuator from MTQ and began tuning with that.

So now I am considering whether to change to Stao's new rear flange plate myself (& what impact that might have on my tune since I can't afford any more tuning now). Then I just have to send back an unused flange plate and two unused actuators to Tao for the refund and go on my way to figure out the e85 conundrum, since more forum reading makes me think the Walbro won't do it happily.

The life of modifying cars. :)

is the z32 in the cooler pipe or before the turbo out of curiosity?

The new FNT version should be more than that too, around 300rwkw. Stao made 320rwkw@20psi.

you going down the E85 path now Han?

    • ATTAKD 356mm Brake Kit for R34 GTT or R33 GTST. Same brake kit as per here from JJ: https://justjap.com/products/attkd-brake-kit-nissan-skyline-r34-99-02?currency=AUD Can confirm these will bolt directly to a R33 GTST with 12mm bolts OR to a R34 GTT (which is what I had) with the supplied bolts and the collets for the 14mm bolt holes in the R34, which are included. Also included is a set of rotors and hats, as well as 2x brake pad sets. 1) DBA XP (street, hills) 2) Forza FR6 (track) These are radial mounted and bolt directly to R33/R34. You will need extended brake lines to avoid them being full stretch on lock - this is common for all BBK's with the bolt point being in the center. In my case I welded another stud about 25mm lower than the OEM one and retained stock lines and fittings. You'll want a BM57 BMC to get the most out of these. I speak from experience. $1800 (neg for SAU people), located SE Suburbs Melbourne.
    • Set of R33 GTST Calipers, Rotors and Pads. Calipers just taken off my car, rebuilt about ~30,000km ago. Rotors have done about ~20,000km total since new. Pads have plenty of meat. One set is DBA XP (road, hills) and the other set is Forza FR6 (track) Still working perfectly, not rusted, or seized or whatever the hell that greets used brakes. All clips, bolts, retainers, slide pins etc included. Also have OEM handbrake shoes I can throw in there if you're doing a conversion. $650 for the lot, SE Suburbs Melboune/VIC
    • I feel I have covid right now. I spent the time between Dec 21 and Jan 31 pretty much working 16 hour days on the car after it got back from paint. It turns out you generate a long list of "things to do" while the car is off the road but functional. After going to visit my mate for a "Couple of hour job" doing the brakes, 3 full days later I got home There was more on the list, (it got added to while sleeping on couches) but as everything on the list got enthusiastically crossed out as it happened, I've actually forgotten what they were. From memory there were bushes that had to be pressed in and out, washer jets to fit, etc. Some Gregging highlights: 1) The panel shop covered up my washer jets and painted over it. Good job, I think. We had to drill the new bonnet to fit new ones, which was understandably extremely scary. 2) My handbrake on the RHS is f**ked. After never adjusting it forever and learning on the fly, this one is still on my to-do list. It tightens when you pull the lever, but at about 10% of the tension that the passenger side does. Thoughts on what causes this would be great. 3) Pouring an entire liter of brake fluid over the reservoir because I forgot how to use my pressure bleeder. DON'T PUT FLUID IN THE RESERVOIR. IT WORKS BY USING PRESSURIZED AIR NOT PRESSURIZED FLUID.   471907729_9242915229093447_2708910336906717367_n.mp4  I can confirm the vents work great though. 4) Some of the bodykit fixings were f**king awful. I'm talking screwed in with what was at most a 2mm screw, and could flap the kit around by hand. Too many others to mention. They came in, went out of my brain forced by other stupid tiny things that came up and "While the car is on the damn hoist we can fix them" which was a mission in and of itself, because the car has skirts and is thus a pain to put on hoists. Because we had to buff the windscreen to get rid of the overspray, I also had to very gently wash the car. The "Run 3 wires" task was to re-attempt another gregging thing which was: The LS1 ECU in Australia does not have oil pressure wiring because the Commodores do not have a 'real' oil pressure switch The Corvettes in the USA do have oil pressure wiring because Corvettes have a real oil pressure switch. The ECU is the same physical ECU. So what I could do is pull the ECU apart, run 3 more pins and run it to the OEM oil pressure ECU, and the ECU should do this. What actually happened is that Greg did this with some not-so-proper-wiring/connectors to the ECU pins which 'might?' be okay put the car back together, and then the fuel pump wouldn't prime. So you can imagine I immediately undid all this work, put the ECU back into it's original configuration, thought I'd do some more research about what connectors the LS1 Ecu actually uses... and try again later. Except still no fuel pump prime. After a lot of sadness and checking/double checking it turns out it was the relay in the boot that controls the fuel pump. All I did was switch the trigger wires and it worked fine. I looked at the relay and it was covered in bog dust and was unknown years old. It's since been replaced and working fine. After I got the actual connectors, and the wires were ran I gathered my strength and repinned the ECU and Voila! I apologize for these MMS  472164532_8829400773820369_5410969472548349643_n.mp4  And even via ODB2 on the headunit, woo. Now Torque Pro can raise hell on track if it gets too low. It has a wonderful EMERGENCY_DISTRESS_SINGAL style warning if it goes below a certain threshhold. 472585876_9345134268844369_146554337148747327_n.mp4 TLDR: Car great. HFM kit works. So much cleaning. Buy my old stuff. Thanks.   
    • That's a hell of a question right there and so broad that you could get 100 different answers and have them all be correct.  To avoid me typing up a 2000 word thesis that doesn't answer your question, do you have specific things you are unsure of? Does the car currently handle in a way that you don't like? Or is it closer to, you think the car drives fine currently. But you'd like it to be better, but you don't know what that 'better' is or what that 'better' feels like?
