had my 1993 GTR dynoed on 4wd dyno 3 months back mods include(all done recently beore dyno): apexi power fc and avcr high boost 14 psi(1 bar), extremely large oil cooler, jasma 3.5 inch cat back exhaust and twin pods. everything else is stock

made 198 all wheel kw and 625 nm of torque...... torque seems good but the kw seem abit low compareing to other gtrs...

please pm with clarification

many thanks jenkies

R33 GTR

Garrett 2860r -5 turbos

RB25 AFMs

Apexi Power FC

Greddy E0-1 boost controller

660cc Nismo injectors

Nismo Fuel Regulator

Bosch 044 fuel pump

Turbo back Fujitsubo Exhaust

290.5kw @ all four.

I'm now going to save for some poncams and cam gears, as I'd like to have full boost a bit earlier (current = 4750rpm), and hopefully be able to put a bit more timing into it to make some more power. I'd love to get 320kw or so, which is max i'd like to run on a stock motor.

Ok got poncams 260/260 9.15mm lift...

I did a before and after run on the same dyno... see dyno sheet attached (green line is new power curve)

Pretty sure there's not too much more I can do unless I build the motor or change turbos.

Previously made 390hp 22degree 20degree intake with a Garagesauras tune at 10-12psi with loads of timing

New coil packs and cam gears and more aggressive tune should see more HP

car has managed a 11.7 with top mph of 120 in 37degree day

will post dynographs

Gday,

Just got my car tuned after being off the road for about 3 years. Ive put an RB26 engine (and an R33 gearbox) in an R32 gtst. The tune is a preliminary one, so ive gotta run the car in and go back in about 1500kms so they can turn the boost up.

The car made 345 rear wheel kilowats on 17 psi and 98 octane. There should be more to come, but after driving it home from Silverwater in the wet, im not sure more power is a good idea in a rear wheel drive application!

The specs are as follows:

R33 RB26 (prepped block etc, compression is 9.0:1)

ARP head studs and rod bolts

General head reconditioning but no porting or polishing

Standard cams

HKS cam gears

CP Pistons 20 thou over

Prepped standard rods

N1 oil pump

Tomei sump baffle and head oil restrictor

R33 gtst 5 speed

Jim Berry modified Nismo 5 puck clutch

Autronic SM4 computer

Autronic boost control

Garrett GT35r turbo with 1.06 turbine housing HPC coated

Tial 44mm external wastegate with 17psi spring

Tial 50mm BOV

600x300x100mm intercooler

Earls 16 row oil cooler

Stainless manifold bought from GCG. Modified with extra support brackets and HPC'd

3.5inch dump, HPC'd and wrapped

3.5 inch Trust exhaust

Walbro in tank pump (255l/hr i think)

Surge tank with Bosch 044 in line (i also used the HICAS lines as fuel lines)

Sard 700cc injectors

Edelbrock fuel reg and modified standard fuel rail

Ford falcon twin thermo fans with 50mm alloy radiator.

I think thats it.

Just gotta get it engineered and registered now.

Car is now running Haltech E11V2 with anti-lag, upgraded fuel system and upgraded coils also just dialed cam's correctly after finding out exhaust cam was advanced a tooth, waiting for re-tune. Should make 400rwkw on same or 20psi boost. New ORC triple plate clutch from CI Performance just installed.

****UPDATE****

problems sorted, retuned, my GTR now makes 424hp@19psi on pulp.

Mild tune for now to assess engines health (it was swung together before I owned it) and then we will lean on it for big numbers. But there is plenty of headroom left in it!

Now to the drags I go!!
