Top RB20 Club... do you have over 260rwkw?

[predator]

guys, just a quick question, anyone fitted a rb25turbo gcg hiflow to there rb20? If not what would be a guesstemate on how much power it could make at the wheels?

around 190rwkw..

[rb20powersilvia]

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

[R31Nismoid]

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

[rb20powersilvia]

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

[R31Nismoid]

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

[silver gts-t]

i got my HKS fconV Pro tuned by the good people at bd4's today..

they do fantastic work, me bleed valve was my set back.

only could boost to 15psi, and even then could do it evenly

[Cubes]

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.

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

[silver gts-t]

sounds like what mine was doing, but hopefully can be solved though

<{POST_SNAPBACK}>

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.

[RB power]

i have a turbonetics 60-1 but cant be much help cos my engines not tuned yet lol

[Roy]

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

So what was the result?

[rb20powersilvia]

RBpower how much power you aiming/hopeing for with your setup? Is yours the ball bearing series and how much did you pick it up for?

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.

[yogi000]

nice work dude

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

[yogi000]

i think its now a hi flowed gcg r33 unit

it taking me 17psi t make 207rwkw and a 2530. so 211 @ 14psi is pretty good i reakon. (i understand dynos are abit diff too)

[Roy]

Yeh BD4s use one of those thingie type dynos too. They were saying it reads a bit higher then that other type of dyno thingie that most places use...i really dont know what im talking about:)

[kwazza11]

So whats your cold starts like with the fcon silver gts-t? mine has very doughy throttle response until its atleast had a couple minutes to warm up.
