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

[Beer Baron]

there is no better way to keep an engine or gearbox in one peice than buying a spare and keeping it in the garage. invariably you wont need it!.

I had the same thing happen with my GTI-R. I bought a spare box as they are notorius for breaking them. and sure enough I never needed it.

[legend01]

The rev limiter was set to 7800 which i used to take it to often in first 2 gears.Low boost was set at 14 psi for everyday driving that said though it was more or less just a weekend car and I only got to drive it for 9 months b4 it went all outa shape but every time it went out boost got wound right up at the very least twice during each outing so fairly often Id say just not for long periods.

Actually same oil as you though cant remember what is was though I do remember looking up one of your old posts to suss out what oil you were running as I new you did a lot of track days

cheers Peter

Stock RB20DET internals, HKS 2530 turbo, 550cc injectors, fuel pump, dump/xorst, fmic. Pulls 220 rwkw on dyno and blows 6.0 ltr SS holdens off the track.

Runs 18psi boost all day long.

Dyno report attached.

Rgds, Grippy.

nice work grippy

i'm running a very similar setup on mine

i made 207......but yours looks punchier and larger power band

[legend01]

thats awesome power graph looks like an rb25 one power all the way

[Rolls]

Yeah is that just the scale or does it come on at 3k ?

booked in for a retune next friday because the stock cat is replaced with a decat pipe (stock one melted and wouldnt let me boost past .9 bar)

[yogi000]

hey grippy,

is that a chipped stock ecu??

was that around the same time as when dr drift was around at mrc?

[silver gts-t]

that afr is shocking.. definatley more power to be had there

Afr looks like a ride on the big dipper

[AD4M]

it did the 330 run at a show, they had the dyno (2 dynos) setup in a tent back to back with a divider wall, a few cars had feedback in the afr charts becuase the probe was so close to the wall...

its tuned better than that chart says

I will get a printout in RPM for the next tune to show how laggy the thing is, 5k it hits full boost

[AD4M]

only change was the decat pipe, oh and more boost

[Roy]

Whats the story with the turbo? Is it a 20G or a 16C. Looking at the power and the lag i would say it may not even be a 20G, perhaps bigger again. Is a Greddy/Trust turbo or a Mitsu turbo?

[AD4M]

rear housing is stamped 16c inside.comp cover has 20g on the plate(its a trust)

comes on around 3ish full boost by 5k

[Roy]

16c is referring to the exhaut housing size. It seems the turbo is the same as mine except it has an A/R exhaust housing off an RB25 or a 13B.

Grab a 8cm or 10cm housing and you will be making over twice the power at 4,200rpm then you currently are.

[AD4M]

spot on roy, turbo was purchased from a guy that had it on a 25

issue i have with changing the rear housing is, it has been modded to mount the tial 38mm gate

im currently building a 30/26 for it so im happy to leave it how it is for now

[iz32]

grippy, yoggi and any other gt2530 owners....

when do you guys get max boost?

[AD4M]

ran it up again on a shootout mode approved dyno so i could get an rpm printout, i left the factory rubber inlet pipe on for the run, once it hit full boost(24psi) it sucked shut so it wasnt a full power run. biggest limiting factor atm is that damn pipe but once we get time we'll knock a hard pipe up

she cracked 366.3 at only 5500rpm but as u can tell from my sheet above it has a slight incline so 370 might have been acheived

afr's go into the 9's once she hits boost :S but i want it safe so not to worried about that

the dyno operators say 400hp is very possible if it gets retuned back into a leaner ratio but like i said im happy to keep it safe where she is

dont have a copy of the sheet atm but heres the rpm/power ratio

2500 rpm = rwhp 54

3000 rpm = rwhp 63

3500 rpm = rwhp 81

4000 rpm = rwhp 117

4500 rpm = rwhp 198

5000 rpm = rwhp 342

it actualy boosts earlyer than i thought, full boost by 4700 and cosindering the power/turbo its pretty good

[Roy]

Another track day done and dusted. Im making a bit more power then previously and it feels like it to. Pulling really hard. I think i was running about 16-17psi.

Engine did not skip a beat all day and still is not breathing a drop of oil at 230-260rwkws. 10,000kms in and a general inspection of the motor is its still in perfect health and not showing any signs of trouble. So next track day in a few weeks is Sandown where the extra bit of power will help so will be running about 19psi.

I will try and get a vid up...i cant believe how well it now pulls in 4th and 5th gear. You can see on the early laps im coming out of corners going for the next gear and im going for where the lever would be if its in 3rd only to find im in 4th and need 5th. Its amazing how well the thing pulls in the top end....lol, the TD06 is no longer for sale. TD06 for life

[Cubes]

Definitely a good thing Troy. If you do the new motor simply give it a freshen up and throw the larger turbine housing on the td06.
