Nistune S14 / RB25DET
(running RB20DET ECU / Type 2),
308 rwkw
Simon, Morpowa, South Australia
S14 with RB25DET + RB20DET loom and ECU.
Turbo was a Garrett GT3076R with 0.63 rear housing. It was running Z32 AFM with
550cc injectors. It made 308rwkw.
Nistune RB20det 373rwkw
Jeff, The Speedlab, Turbotune, South Australia
Std Pistons and Rods
Std Camshafts
ACL rings and bearings
Metal head gasket
GTR inlet plenum
T04z Approx 33psi
850cc injectors
Nistune R32 board tuned by The SpeedLab
This was a workshop experimental project to see how much power could be made
with a standard rb20det. Personally i was surprised that the standard pistons
could handle more than 500hp. Somehow the engine is still running and shows no
signs of blow-by or failure. However it was only ever run on the dyno at a fast
ramp rate. I am sure if it was loaded up hard on the road it would fail
eventually.
Some special cam timing and other little tricks were used... No problems
controlling this with a standard ecu. Is there a more powerful standard internal
rb20 out there?

Nistune S14 board tuned by The SpeedLab
This was tuned a year ago. About 2 weeks ago the same car was run again and made
315rwkw on 23psi. Reliable and consistent tune with Nistune.

Nistune RB30E+T
Standard Comp fitted to VN Commodore (Type 1), graph for 274rwkw, peaked @
286rwkw
Luke, Victoria. Home tuned at final tuning performed at Status Tuning,
Victoria
The car did end up making
286rwkw @ 20psi on a 100% internally stock RB30 high comp motor. - although it
tried to squeeze the gasket out the side of the block the next day! (no
detonation marks on the flame rings, just stretched!) - but not until it ran a
12.3 and a highest of 116mph. Only managed to save the dyno sheet for 274rwkw @
20psi, but thought it might be worth chucking it up on the results page
The full specs and details of the hi-comp boost experiment are on the
calaisturbo forum http://calaisturbo.com.au/showthread.php?t=143539
but in brief, 100% stock 250,000km rb30 motor. only two maintenance items i'd
done were ACL monotorque head gasket (aftermarket stock replacement) and some
fresh valve springs i had lying around. - moreso preventative maintenance
really! - Standard N/A cam, no head work at all etc. Motor was a little down on
comp accross all cylinders, just a little tired I think. Z32 AFM and 750cc
siemens 3145 injectors.
Anyway - The turbo is a GT3582R with .82 rear. I have a "4800"-ish
stall converter (intended for the built motor I'm putting in now) - it seems
that by the time my foot touches the floor, it's at full boost! - for e.g: http://au.youtube.com/watch?v=UWwXYXq_S9w
Not only did the car pull a good peak power number on the dyno, Trent @ status
tuning (I highly recommend them) did a remarkable job at making the car drive
smoothly and happily! - no grumpiness, and he managed to smooth out any
reversion issues with a few magic tricks! - after it was tuned professionally, I
would have been happy to throw the keys to my girlfriend (in the dry) - which is
testament to the tune-ability of the system!
NIStune-powered 200SX
S13,
382rwhp @ 1.7bar
Noel Uhure, United Kingdom
Just a bit of feedback on my NIStune-powered 200SX S13. Had NIStune installed for 2 days (no issues whatsoever), and managed 382.8bhp & 326.2lbft @ the hubs on a DynaPack dynamometer. The run was cut short due to mechanical sympathy. Quick spec: 1030kg, standard 1.8 CA18DET (2 x standard headgasket + over-torqued head), T70 (Garrett T61) @ 1.7 bar, 510cc injectors @ 2.8bar. No knock at all. The AFRs are lean off-boost due to a leaking V-Band. Just like to say a big 'Thank You' to Matt for designing such a wonderful management option. This could well be the highest power from a non-forged CA, trying to find out what else is out there. Having a lot of fun exploring how far I can push the standard engine. With a new (fully forged) build on the way, I'm going to stick with NIStune (obviously) and standard ECU with a twin-MAF set-up.
NIStune Results on RNN Pulsar GTI-R, 418rwhp @ 1.5bar
Ed, Fusion Motorsports, United Kingdom
Well had my first car with
a map near completion dyno'ed today. Its a RNN14 Pulsar GTi-R with Fusion 3071
turbo, 800cc injectors, Q45 MAF, Front mount intercooler, forged engine, 2.5
inch exhaust etc. Tested on a dyno dynamics rolling road using SHOOT_44 dyno
mode. Could have got more, but clutch is near its limit. Looking good I'm quite
pleased.
Results: 418bhp@ 7250 rpm 1.5bar boost. 380lb/ft @ 5250. 328bhp @ wheels. 310ish
lb @ wheels. Q45 MAF tops out (about 417HP / 310rwkw)
NIStune on VL Commodore RB30ET, 215rwkw @ 9psi
(standard RB30ET AFM)
RB30ET with GTR injectors, Current result is
about 215rwkw @ 9psi. Michael found that factory RB30ET MAF peaks out at
190-200rwkw on this run. He is getting a Z32 MAF which can measure up to about
320rwkw.

here from SRs that he has tuned.
