Maybe we can make this Sticky?? Have a comparison against other GTR's with mods or in stock form.

Got my car dyno'd today, after fitting the PFC & Cam Gears, here's the result & my list of mods.

MODS: GTR Series 3 98model

Power FC & Hand Controller

Cam Gears (Settings +4 & -6)

Stock Turbos (14psi ~<1bar)

Turbosmart bleed valve

Exhaust - stock dumps, 2.5 front pipe into 3inch, stock Cat, 3" from cat back

HKS Pods (No CAI)

Total 249.1kw @ ALL FOUR WHEELS

Thanks to:

1. boys at ICE for help & advice

2. Merli from SAU for letting me know it's kw@all four wheels, & not rwkw.

'95 Series 1 GTR

  • Apexi Front pipe, 3" Cat, 3.5" Catback
  • Standard turbos and 'cooler
  • Boost @ 1.0 bar (Blitz Dual SBC)
  • Power FC
  • HKS pods

234.8kw at the rears

So, theoretically, with cam gears i should get a 15kw increase.. that sounds about right.

If you think these figures are overinflated, that's because they were done in RWD...

If the driveshafts were left in and the cars dyno'ed on a 4WD dyno, they would read about 20kw lower.

But a GTR is in rwd mod until traction is loss so in the real world that figure is probably correct, unless of course your doing 8K luanches :D

that seems a bit high for stock turbos!

u should have used ben at race paces dyno it gives much more realistic dyno readings

Hi INASNT,

They're stock as they come.. The car will be at ICE later this week or next. I'm getting the HKS EVC IV fitted, & need new spark plugs.

Hi Merli,

The dyno was done in 4WD!! "shootout mode, I think??".. not 2WD. It was done at Subaru Docklands, in Victoria. In fact it hit around 265rwkw, but that's when we dropped the boost back.

Intersting my PFC Hand Controller, shows my knock levels to average around the 13mark, max I hit was 21... is this OK?

Thanks

Yup... absolutely true...

That's why a GTR that spins up 250kw @ wheels will be faster than another RWD car that spins up 250kw @ wheels...

Because when you actually take them to the road, the GTR is making more than 250kw @ wheels :) :) :D :D

Sorry mate, you said in your first post (and this one): 249rwkw, which means "249 rear wheel kilowatts"... Got GTRs dyno'ed on an 4WD dyno, we usually say "249 kw @ all four" so we can differentiate ;) Hope that helps!

Excellent power figures for those mods! I think we all need to get some cam gears for our GTRs soon too! Did they make a big difference in spool up time as well as a good power increase?

Oh, and great choice on boost controller! Let us know how it goes and how it compares to the bleed valve!

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
