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

[Interloper]

Hi Roy, thats a great result with the 8cm TD06-20G, where did you take it to get tuned? was it ben from racepace?

[Roy]

Thats the one, very happy, hell i even got good fuel economy coming back from PI. I estimate ill get over 400kms from a tank of sedate driving

And how big do you call a tank??? 40L? Or do you run it dry?

[Interloper]

And how big do you call a tank???  40L?  Or do you run it dry?

If i may.

A tank i would consider something around the area where the empty fuel light would be almost, or just on.

Thats pretty good Troy, i can get about the same or just over 400km if all i do is mostly highway, but thats in a heavier GTS4 so i'm not compliaining

[Roy]

A tank is when the fuel light comes on having filled it up:) From experience i can usually get another 50kms after the light come son, in fear of runing out of gas i have never pushe dit any further.

Though with the std turbo/ECU driving from Sydney to Mudgee and back i did get 610kms before the light come on, i wont try and repeat that with the current setup and tune:)

I only just found this thread so i thought i would post up where my engine is at.

Last dyno run it made 240.6KW at the rears. That was on a max tune with the mods at the time. I have since been upgrading parts and all i need now is a better turbo.

I have been told that 300rwkw should be "a walk in the park" for my engine. So as any logical person would do i am aiming at 350rwkw. I am hoping to have this done before compac attack in April but unfortunatally parts are taking there time to turn up.

I have no 400m times yet as this is my everyday driver and i have not been able to get down to WSID and had the money to not care if it breaks.

[Roy]

Good power, whats been done for 300rwkws to be a walk in the park?

Very interested to hear what if anything has been done to the head?!?!

[DCIEVE]

I fairly sure it was in hpi, has 26 rods, 2535 etc. A very nice z

[Trust33]

a 2535 isnt big enuf for 300atw.

[Trust33]

i want that sort of power ohh.

The light means 100kms man Thats weak

So how big is an r32 tank tho? I would have thought with a bigger turbo tho you would be spending less time on boost and therefore saving more petrol?

What motor are u talkin about here?

What sort of mods do you have?

"300rwkw should be "a walk in the park" for my engine "

Man thats a milestone on a RB20.... Thats a Giant leap for mankind !!!

[KIL.08S]

DCIEVE yes it is the one in HPI, when it was featured in hpi it had not been tuned yet but made 220rwkw shortly after, i got the car retuned without any mods and it made 240rwkw. when it made that figure that was as high as it could go as it was being restricted by the injectors and fuel pump (all GTR gear). i am now in the process of replacing these pieces and have just bought a new turbo. i will be getting the car tuned in the next few weeks so i will post up the final readout. If i dont manage to break 320rwkw then i will be getting a nitrous kit to make up the difference.

as for the other modifications this is a short list (you can understand that i do not want to advertise what is under the bonnet for thiefs)

hks 272 cams

tomi 2.3 stroker (apparentally)

hks cam gears

ECCS plenum (changed from NCIS)

i am assuming some head work

mangled exaust (also getting repaired)

[Roy]

What turbo to make 240rwkws? Any dyno chart

[KIL.08S]

i'll see if my scanner is working if it is i'll post up the dyno sheet.

the turbo was a HKS 2535. i think the car used to be a track car thats why there is still a smallish turbo on it... that problem should be solved by monday GOT LAG lol

[rednut]

I haven't reached 200rwkw but that it is certainly the next goal in my project...

My RB20DET now looks like this after about 5k

Turbo Back 3" exhaust system (catco muffler & cat)

modyourcar 600x300x76 FMIC

Apexi Power FC

Sard adj Fuel Pressure Regulator

Walbro 550hp 250lph in-tank fuel pump

stock injectors (about 80% duty cycly i think)

stock turbo

With 1.0 bar boost, all this netted me a max of 166.3 rwkw with about 6 other runs between 160 - 166 rwkw. I'll scan the dyno chart up tonight if I can because the power lump below 3.5k is awesome, it's really torquey and just pulls from 3k all the way to 6k - very smooth and very strong. The next item on the shopping list is a GT2530 or similar turbo, so stay tuned...!

[DCIEVE]

kil.08S Nice work! what snail have you chosen to replace the 2535? I look forward to your results.. Running td06 hybrid myself but plenty of other problems holding it back:(

[FATGTS-R]

KIL.08s.

You mentioned the plenum was changed over to an ECCS type from the previous NICS type.

Is this power being made on the older red top RB20, 12 port head?

[KIL.08S]

no, it has the new head but still has the red cover. i have been asked a few times "is that a CA18?" you just nod your head and agree its jsut easier sometimes.

the turbo is the equivelent to a garrett T61. If the turbo is a hunk of shit i might just get a 3040 or something simmilar.

[Roy]

Well, i refuse to let this thread die, its turning into a bit of a 'Tales of a thrashed RB20DET':)

Tonight went to Calder drags, did 7 passes in total, using 7,800 shift point for all gears on all but the first run where i used 7,000rpm rev limiter. Was running 15 psi and bagged a best run of 12.9 @ 112mph with a 2.2 60ft time.

Did two 114mph runs but 60ft were both in the 2.4sec bracker:( Need to learn how to drive.

So in th epast 3 weeks the car on the same sump of oil did a Sprint day at Phillip Island, Drift afternoon at Calder and drags tonight at Calder...thing is still runing perfectly adn g'box still lives.

The past 3 weeks are restoring my faith in the old RB20s, last year i encountered problems everytime i turned the key.

If ppl are getting the sh1ts with dribble then let me know, and ill stop posting, but i thought some would be interested in reading about an engine that is getting driven regularly at various events... baby steps into how durable these things are...next Saturday Phillip Island again, Sunday Sandown, but before then soem fresh engine, g'box and diff oil:)
