Read this thread - ultimate RB "pull hard" setup, make numbers in the range of GT35R peak power but spooling similar to the smaller GT30 range turbos:

http://www.skylinesaustralia.com/forums/topic/426059-forced-performance-hta-turbos/

+1 for lithiums post. HTA turbos are weapons and will give you the best of both worlds. Will give you 400rwkw and the same response as a gt3076.

You'd be mad not to have a look basically

I disagree with both these clowns :ph34r:

LOL kidden, HTA or GTFO!

Was just trying to be helpful, was Garrett based and a lot of people don't know there is a bigger world than Garrett who have been all but left in the dust. But point noted, I have meant to have given up on trying to be "helpful" on these forums - just got a brief burst of enthusiasm for this place after finally actually meeting some SAUers... as you were :action-smiley-069:

Left in the dust is a little excessive, I love my GTX and the results are excellent imo. Keep your HTA fanboi speeches for the impressionable boys in the FP thread. Considering you all talk about them continuously I would find it hard to believe someone hasn't heard of FP, Precision or BW for that matter.

I think Garrett is still king of reliability in most peoples minds... for good reason. If that means they are a little slower in their design rollouts and test their turbo's for longer, I am all for it. I have a Precision 6766 on the bench at the moment, not sure I like how thin the compressor blades are. Hopefully they haven't gone too light weight just to beat the competition...

No need to sook about being 'helpful on these forums', everyone else is here for the same reason. If you don't like people having opinions that differ to yours, better stay off the interwebz.

Hi all

I read some comments here and it looks like people prefer GT30 for around 290-320rwkw power. GT30 will come on boost harder in the mid range. It looks like a more efficient option on paper.

One thing I don't understand is why would someone want harder pull in the mid range when it will create more problems with traction unless are on 3rd gear. I have rb25 with GT35 312rwkw and I have problems with traction on 2nd with 265s and shimmed diff. I've driven similar car but with a smaller turbo and it had even less traction.

Correct me if I'm wrong, since I'm new to this. If I floor it at ~3000rpm it will pull hard almost instantly and easily break the traction on a smaller GT30 turbo compared to GT35 which pulls from ~4500+ but has smoother transition from no boost to full boost.

I have read many threads about this but not many people are looking at it from this angle

Cheers

You'll find your traction control switch at the end of your right leg; when traction starts to break, lift right leg slightly.

Also on most good ECU's you can do boost by gear and just have less boost in 1st and 2nd.

No reason you can't just lift off slightly though...

Maybe of interest, I found this helped with controlling boost on my car:

http://www.gktech.com/index.php/v2-s14a-s15-eccentric-throttle-wheel.html

It will work fine on an RB25DET. The standard wheel opened the throttle quite a lot with little pedal movement, where as the GKTECH one is the opposite, ie a smooth logarithmic opening of the throttle, where 50% pedal may only be 30% throttle opening. (not sure about exact numbers)

Its good for peaky responsive turbos.

the best action ive had was with a GTX3076, 4000rpm's = Hammer time, 1st and 2nd at WOT =Black lines layed for 50meters which is f#$k yeah feeling.. 3rd= hold on

If you can do this then you know you got a wild ride, the rest is up to you and the tyres, suspension and right foot control, but personally this has set the bar for me... and now disappointed with anything less :(

Go with the Gt35. They are the bomb diggity.

They also have plastic cage bearings afaik, where as the GTX has steel cage. Hence the reason the old diesel designed GT35's have a higher failure rate. It's one of the Garrett turbos I wouldn't recommend.

Go with the GTX3076 imo for a similar power figure and quicker spool.

      yeah, that happens too.  I'm really enjoying 4WDing at the moment, seen a few beautiful spots and want to go explore more of this enormous country.  The 370Z got a clutch LSD in it and a track day, great fun.  Getting the back end sorted out really rejuvenated my enthusiasm for driving it hard, the viscous one is poo especially in such a short and wide chassis.  The VLSD unpredictability was more benign in a long and skinny Skyline.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      Yeah I would like to try and get a ADM car to reduce issues with insurance. I've decided if I end up getting this car I will set it up to be a sleeper build, leave it looking stock/dad spec on the outside I wonder if you can just drop in the 400r/Red/Z ECU or better still use a flashing tool to copy the map off one. Backup the factory map and then flash the 400hp cars onto the 300hp cars ECU?
