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

[Roy]

Low rev limit? LOL look at the boost he is running! I wouldnt rev it that hard either especially since its making nice power relatively early. Especially with a bottom end that is worth dollars...std bottom end. Hell why not rev the ass out of it and wind boost into until your ears bleed as it only owes you $400-600

[Wheezy]

That power curve looks fierce.

Does it come on like a light switch or what?

[huddy]

i've only driven it home from dyno in stealth mode...lol i did gas it once... but it's hard to gauge as i was too worried about everything around me (especially coz i was on a trade plate)...

I'm on the track saturday for testing

It's only a little bit laggier than my setup with the hks2540 according to the graph

[Roy]

So its killing me...what was the prob that has had it go from tame to "can i have my teeth back please"

[turboedsloth]

MARCH 11th is tuning day for me. cannot wait to drive this thing again its been a long 11 months. will post dyno sheets up when shes done

So its killing me...what was the prob that has had it go from tame to "can i have my teeth back please"

if the thing cant spin to 8000 it doesnt deserve to be called an RB20 (hybrid or not)

[huddy]

haha... ahwell... it works for me (i hope) lol.

ROY - not 100% sure hey... i reackon it came down to the wastegate leak/exhaust leak... i could be wrong - but thats what i reackon!

[yogi000]

I didnt make 260rwkw but i thought i'd share my rb20 powah!

Finally managed to install 256 tomei cams in my rb20 and have it tuned.

Previously made 207rwkw @ CRD with 1.25bar (without cams)

Without any cam timing it managed 225rwkw @ CRD with 1.25bar

With cam timing tweaked for response and torque it made 215rwkw but gained everywhere else.

The map is running much richer.

I dont have a print out, i will ring jim and ask him to fax me one so we can compare against the old tune.

[huddy]

good results!!! i've got my tomei poncams on the way also

How much did those cams set you back mate?

PM me if you don't want to post it up

[AD4M]

for a laugh on the weekend we decided to run mine on the dyno to see what would happen, the motor is tired and breathing hard... but we still decided to give her 25psi

366rwhp and afr's that were below 10.0 across the run hahaha, we're still laughing that it held up!!!

[turboedsloth]

300.2hp at 20psi with the wastegate spiking and no boost controller. need to go from 38mm to 44mm to help it out. apparently my 6boost manifold is TO good, love the sound of gate, hits boost early and hard, have to go back as soon as i can afford another gate to get it retuned and a few niggles sorted out. mick recognised the car aswell adam. hes a champion

top work mate! should have let me know you were coming down i would have loved to see the finnished setup

get a profec b spec II on it if you havent got an ebc, mick can get it to come on a bit earlier that way. spewin bout the gate being too small, ive heard of 26's with 6boob manis doing the same thing so i can only assume it might be the way the collecter is plumbed?

which ecu did you use on it aswell dude?

[lilmissr32]

My RB20 made 393rwhp or 292rwkw and was pretty much at its limit. It had (to cut the list way short) GT3540R, forged bottom end, LINK ecu, 555cc injectors, 550hp in tank Bosch fuel pump..... It also had stock rods, stock head and stock plenum. Was very laggy and also had very little torque unfortunately so was very strong at the mid and top ends but lacked bottom! Best quarter mile was 12.9 @ 123mph with 2.8 sec 60 footer - the mph was up there for an 11 but you can tell with the 60 footer that I could never get the power down! Now I've gone Tomei-prepped RB25.......

[turboedsloth]

has a profec b spec 2 he disconnected it to stop it goin to 30psi at 4grand, its running straight off engine vaccuum atm. got a EMS stinger in it. yeah mick was saying he's had some xr6t's do the same thing. just reckons there way to efficient. should be back up there in a month

[legend01]

Been A while since ive been in here so how many have cracked the 300rwkw now ?

[yogi000]

i got them from nengun, 2 years ago.....i think it was $800

[Justa32]

got my tune, i rkn its a pretty responsive setup with nice mid range, but im looking at dumping the apexi turbo and upgrading to a 3037s pro

tune was done on 18psi

Any modifications needed to fit HKS 256/264 camshafts 10.5m to an RB20 motor?

Is it just a matter of pulling the old ones out and putting the new ones in and would it be best to get adjustable cam gears or will just camshafts + tune be ok?

[limpus]

No...that amount of lift will require heavy duty valve springs...

Cam gears will give very little adjustment but a tune is usually sufficient...
