[amosite]

'90 model, 85,000 klms with up to date log books

Near stock, currently sitting at 286 rw kw (approx 383 rw hp)

Currently being tuned for more mid range as it seems the turbo's are

at their max.

Mods:

Kakimoto 4'' from dump pipes

Roguepi Hard pipe intake and cross over pipe

Apexi 115mm intercooler (couldnt find a 130mm one)

F.E.T ignition coils

IRIWAY plugs (could be iritop, cant rememeber)

At this stage, the car was making 240 rw kw (321 rw hp)

Added an original Profec B- now making 260 or so rw kw (252 rw hp)

on 1 psi less then previously

Added Power FC Dejetro (AFM's still fitted) 286 rw kw (383 rw hp)

Cam belt being done along with cam gears, waiting to hear back from tuner

but probably wont make any more power. Hopefully it wil have a bit more

mid range.

Looking to get 400 hp atw with stock turbo's but not sure what I can do next.

My brother is suggesting alloy pulley kit (Water, powersteering, alternator)

along with a billet 5.2kg flywheel which should free up some power putting

it close to the mark. Everyone on here laughed when I said I wanted 300 rw kw

(400 rw hp) with stock turbo's. Im not far off my mark and havent done half the

shit they said I would need to do.

I will update this with a scan as soon as I get the car back (next week maybe)

P.s Ramp rate is 100, should be good for a flat 12 if the clutch holds it. This is also

a summer tune. It might get closer to 400 rw hp in winter but thats not the point....

Update to Post #13

I've had my GT-SS turbos and JUN cams fitted and fettled. Mid range power improvement is dramatic. This is like a new car, almost no turbo lag whatsoever. The car pulls hard in any gear. I use for daily driver and occasional track day. The dyno run speaks for itself. 500Nm of torque at 3000rpm! The tuning was done on a Dynapack 4WD hub dyno. 488hp @ A4W. Turbos running at 1.5bar.

Further to my previous post above here is the finial figure

With the addition of cam gears and finishing the tune it broke 300 kw (403 hp)

on 11.8:1 AFR

Paul (Pulse Racing) double checked that I wanted it richer. I confirmed- FAT in the mid range,

around 11:1, then to Mid 11's and above 6500 keep dumping fuel to cool it. That he did and the

result was 6 rw kw less.

I would say that this particular car would probably make 305, maybe 310 rw kw on 12.2:1

but I would rather be safe.

After driving the car, its fast but not really as fast as previous cars. I will drive it tonight to

get a better impression of what its capable of. If I keep it I will put the 550cc injectors in,

SARD Fuel reg and the GT3040R on it- but limit it to 350 rw kw as per Pulse/Advans advice

(stock rods). Only problem with is with the next stage I will need to change EBC's as I want

to run 22-24 psi as it spools up then taper the boost curve back to 18-19 psi above 5000 RPM.

We have retuned the car on the street and will be putting it on the dyno tomorrow now with 100octane shell fuel and more timing with 1.5bar boost we hope to make around 430rwkw with bucketloads of power as fullboost is by 4500rpm

Some big numbers in here, makes my figure look lame...

1990 R32GTR

77'000kms

It did run 400rwHP, and suprisingly had plenty of injector duty cycle left (And Boost), but 2 degrees was pulled from the timing as at the end of the day it is an old motor and no point in killing it just yet!
