[ZENNON]

Manual R32 RB20DET

With

POD, FMIC, 3" Turbo back exhaust, empty Cat

on 11psi running on 95 octane (dont ask) got 140RWKW

Since then added

RB25 Turbo, RB26 Injectors, Nistune, cheap 3" Cat (to be legal)

And on 15psi running on 98 octane got 190RWKW

Yes tune needs a touch up but I'm happy with the results

considering how stock the engine is and how small the turbo is

[dato$2nv]

R32 GTS-T 1993-- Before i bought it 200.7 rwkw @16 psi

Since ive got it

Im measuring 550km on one tank (40L) with highway driving. 350km for city driving...

Thanks to the guys at Hyperdrive!

Retuned the motor last week at AllStars in Malaga.

Made 295whp @18 psi, 1.3 bar, pretty happy with that. made 20 odd hp across the board too.

the car felt better even from the carpark.

Changes made was,

Rb25 intake pipe before the throttle (bigger than 20) -$free

New pipe was made from the afm to turbo, made from truck intercooler piping (spools faster and makes impressive suction noise)-$free

Bosch 044 -$100 lucky score

2.5m longer vacum line to waste gate, open little later -$5

Cleaned air cleaner pod -$free

Cleaned intercooler core -$free

Leak free Bov!

and other air leaks fixed.

Run on 98ron fuel.

175-180rwkw at 14psi with slight misfire.

Getting retuned at 18psi once I have unfouled plugs and some Splitfire coils.

Got it tuned to today at 18psi with yellow jacket coilpacks.

Would only spike to 18psi and trail off to about 16psi.

Got 210rwkw, had a really bad batch of fuel though. Had to knock heaps of timing off compared to last tune and even then its pinging, siphoning the tank tonight and getting some better stuff.

Just so everyone knows only buy Synergy 8000 from Mobil, don't buy the '98' that some of them are selling as it seems to be completely different.

RB25 turbo @ 13.5psi

NPC 5 puk clutch

Pod filter

500hp walbro internal fuel pump

cooling pro Fmic

greddy catch can

oil cooler and oil filter relocation kit

That dyno chart is not quite a full run as the car was having trouble at the time with boost and a misunderstanding with the mechanic thinking it was running 28 psi when infact it was only running 14. so he backed off in the top end.

The car has since been fitted with a std series 2 rb25 turbo and seems alot more responsive and angry up high. I am just waiting to get a fuel pressure reg and I will get her back on the dyno.

Ford Lightning MAF blow through, Tomei 270 cams, Tomei valve springs, Tomei headgasket, Rips intake manifold, Protech-fabrication turbo manifold, Stainless 02 housing made by Protech-fabrication, Precession SC61 turbo, Tail 40mm gate, Sard 800cc injectors, Supra TT fuel pump, Nistune Type 2 board, HKS EVC 4 (not hooked up at the time)

398Hp @ 16.8psi Couldn't get my nistune to listen to me so basically it was set for the injectors and maf on the stock map. Ran really rich then started to go lean up top so I'm going to rewire the fuel pump for next time. If I can get control of my map I'm sure I can hit over 400hp at the same boost levels. Pump gas used for the runs.

3" straight through with 5/6" cannon muffler

Manual Turbosmart Boost T

A touch laggy but mainly using as drift car at Barbagello so a track specific setup anything or anywhere else would use same turbo 0.63 rear or 3071r with 0.63 rear housing or Trust TD06g for little more response

alot of time etc spent on oil system to get that right and up to standard for harshest conditions

Am pretty happy with the setup .. has 400hp in it may go there if put a 25 g box in it... only really want to add a Plazaman plenum to shorten cooler piping and possibly increase response and mid range a touch and a 6boost just because
