i thought the rb25's were making atleast 230-240kw atw with this kind of gcg hi-flow turbo, about $2000 that i seen in another post. I maybe wrong so please correct me. Just thought it would make a bit more power than that on an rb20. thanks

Yeah, thats on the RB25, 500cc more.

unless you screw a stupid stupid amount of boost into it you might get close to 230/240rwkw.

I noticed another post your trying to build a 280rwkw RB20... good luck as its a mission with the best advice i can give of... drop 40rwkw of your peak and you'll make it a lot easier/cheaper

Thanks R31NISMOID ill think about the advice.ill still wana try for 280 - 290. but if it becomes to much of a task, price and brain-muddling wise 240 maydo. What is the rb20 gearbox rated at, what type of power could it take? It wont be thrashed as i would only use that power occasionally.Also what do you reckon about these turbo's both from turbonetics to make this power? Im after something that will spool fairly quickly and stong up top. I haver all my other parts sussed but the turbo is the main concern.

The 60-1 Performance Turbocharger

Representing the careful marriage of a unique high flow/high efficiency compressor section teamed up with a T4 turbine section the 60-1 has proven itself in every competitive motorsport application from drag racing to bonneville. Available with either the standard (4” inlet, 2.5” discharge) compressor housing or the 60-1 HI-FI ( 2 3/4” inlet, 2” discharge) compressor housing, the 60-1 will outflow any standard T04B with ease! (The 60-1 HI-FI will deliver approximately 90-95% of the flow capacity of the standard 60-1.)

OR

All T3/T4 Hybrid Turbochargers are available with the patented Ceramic Ball-Bearing option highlighted in the Ceramic Ball Bearing page. The Ceramic Ball-Bearing T3/T4 Hybrid series offers the fastest spool-up available. Coupled with extreme durability, the Ceramic Ball-Bearing concept provides unparalleled performance never before experienced by the turbocharging aftermarket. All T3/T4 Hybrid's are custom matched for specific applications. Airflow ratings from 250 HP to 500 HP are available. Contact a TURBONETICS Turbo Specialist for application assistance and availability.

The first one my mechanic told me is a ball bearing and is rated at 500hp.

Any help would be awsome. Cheers

I suggest (again)

read this thread, all 48 pages of it.

Posts by a number of users in this thread (Roy is one) will give you the turbo specs and what you need to get it to 240rwkw or there abouts.

60-1 comes in both bb and plain bearing

Had mine on the dyno today. A few problems but won't go in to it as its not an RB20DET.

Besides the point.. We were talking about a nice little R32 there.

THey bolted a GT3040 up to it with a .48 turbine housing from GCG, boost control was erratic, multiple forms of boost control were tried, boost would constantly peak up then fade of peak up fade off..

It was put down to a bad match turbine housing/wheel match.

A GT28 of some sort is going on it. :D

With the GT3040 .48 it made 6psi by 4000rpm, not too bad, just a pitty it didn't perform. :huh:

60-1 comes in both bb and plain bearing

Yea i think he said 1200 or $1300 for the plain bearing and 1950 for the ball bearing what do u think about it? I just wana try something a lil different than the usual 230-240kw, not saying that its bad or nething, i might end up doing it myself, I wana see what else can be done with the rb20 and give use some feedback how it goes.I just need some answers for the time being as i wish to have all the work complete within these 2months.

I have gone through all these pages but there are new things people are trying each week and wana be upto date.

thanks for any help u will bring foward. :huh:

I have to say, BD4s were pricey at times, but like anything you get what you pay for and the guys were always great. They dotn do anything by halves and dont do band aid fixes (My experiences anyway over 4-5 years of using them)

In my eyes one of the better places in Sydney...and one of the few that would work back late on a Wednesday night welding up control arms for me as i had to be at the track the next morning :huh:

yeh Tom was working back on mine aswell, other guys looked like they wanted to go home, hahaha

i couldnt believe how detailed the HKS software was, u get what u pay for but Tom wont over charge you, he will just expect a lil more $ for alot more work.

i ended up with 211rwkw @ 1 bar, no point tunring up the boost cause it would only result in larger pressure drops..

next time ill be there with a EBC @17psi, should do 220 easy.

What turbo? I thought you were running an R33 RB25 turbo?

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
