aw/rw = same shit anyway.

Not really but to certain extend yes.

There's someone I know of in Brisbane that dyno-ed his 32 GTR on rwd and awd mode the same day on the same dyno. The difference in reading is around 10kW. But the difference isnt THAT great and definately not worth the extra money for awd dyno tuning.

Thats prob why Racepace (Working on mostly GTRs) have only a rwd dyno instead of awd...makes sense...i always wondered why dont they have a awd dyno when all the GTRs are 4wd...

10kw is the same shit to me :P

Its been proven by a number of people with over 400rwkw/awkw that any differences are so negligebile its not worth splitting hairs over.

This is with a factory transfer case etc.

With a modified transfer case, its a different story but most punters are not in that category

Hi Guys,

Wanted to know that how much kW can you get on standard turbo and engine, but with below mods :

- Exhaust (Highflow)

- PowerFC

- Cam Gears

- Bleed Valve

Any idea anyone??? Car is GTR33....

Got 264.6rwkW after the above mods!!!!!

very impressed......

RPM cam gears supplied by racepace....

14psi boost and chris from racepace tuned it.....

nice....did the cam gears make much different? i am thinking of getting them too...but not sure of their exact use on the car yet...still due to researching that...lol

it makes difference.....

car accelerates and takes off faster than usual......

surely you have to get it dialed in once you fit it.....

ask chris at racepace....he'll let you know.....

thought it did make difference in response....but when i am rebuilding my engine to hold more power ill be putting the HKS variable cam in which come with cam gears too i think...so thats when i am planning to put them in...but still need to look around for the best combo i can use to make my baby "fly"...lol.. :P

You do know that HKS V-Cam is $5000 on its own, just for the variable timing.

Thats not including the 8-10k for the rebuild and all the rest :woot:

HAHAHA!!! YUP :P itll be done one day...if i get hands on a blown up RB engine to practise on..i might do it myself with my machanics guidance otherwise i am planning to spend around the 20k mark on the engine for my car to pull SAFE 400+awkw...might even make it a bigger block..but will do as my machanic instructs...then work on suspension and make is a nice quick track car..(my dream) :P

There was a test done with VCAM on/off lap times, didnt make much of a difference. But the test car already put out 650HP irregardless, so i guess the argument to have one is marginal

Yes i did watch that video when i was researching about the combo of mods i should do on the car...but the guy who tested it and the comparision video did show a VERY quick response time and the engine was able to rev much quickly with the Vcam on...thats why i am PLANNING to get that done too...but its still in the planning mode...when the time comes for me to do it, new things might arrive that might interest me...lol..

Try it on a different Dyno and you might get the same result, i wouldn't worry about that 20 odd kw differ.

+1...all dyno does give out different readings..so gives more others give less...if the difference is around 20 kw...its more likely both the cars are pretty equal in power...

and peak rwkw is a single figure at any one time

it hardly explains the cars acceleration and how it performs on the street

if johnny where you said it makes 232rwkw and the other makes 264kw

it could be dyno differences, how it is strapped down, air temp correction etc

as long as it feels quicker on the street its all good

the only comparison that is useful is your same car on the same dyno each time

when you do mods, you check before and after, as long as the power goes up, all good

its only if you add mods and get no gain then you need to check it

id perfer to make less rwkw (vs higher for bragging rights) and have quicker times

:) +1...spot on...numbers mean nothing as long as you can get the times better...and its only 20 odd kw diff...so nothing really to stress about...

      Rob's S Chassis track cars. Now with more s15 and less 180sx

      By robbo_rb180 · Posted

      A little more work this week.  Fitted astra power steering pump in the boot with a lowe fabrication bracket. Gave the pump a good clean, fitted Anderson plug and high pressure fitting. With the intercooler being flipped under rad support factory headlights weren't going to work. Ordered a set of origin battle lights, they arrived so got them test fitted. Will require some fiddling to fit nice but was an easy quick option for now. And today we pulled out the manual Rb gearbox and test fitted a ZF 8HP50. It will fit with some casting tabs cut off and small tap of the tunnel with a hammer. Pick up the adapter plate Wednesday so hopefully all bolted in Friday and measure for tailshaft which will be a 2 piece. Been doing a lot of ecu, pdm and tcu loom design so when comes to wiring it in a few weeks will all go smoothly.

      FYP. Sadly. Even bolt cutters wouldn't take 2 sec. But in the days of 18v angle grinders, nothing is safe.

      One piece driveshaft I would recommend a dual CV setup otherwise stick to OEM. I have heard most one piece driveshafts cause excess vibration otherwise. The transmission grind I'm quite familiar with. You can try shockproof gear oil, otherwise you need a new transmission. The shifter is extremely simple on these cars. If you want pull apart the assembly and replace the plastic bushing but I doubt that fixes anything. The tail light issue is very common, unfortunately new tail lights are long discontinued. The trunk antenna going up always is because your radio doesn't have a true power antenna control, just remote amp power signal. There is a blank switch plate that you can pop out and install a switch for this or alternatively source a head unit that has proper antenna control. Throttle body sticking you have to disambiguate by disconnecting the cable and seeing if the linkages are the problem or something else. There is a procedure to adjust them, refreshing them is also somewhat involved if that's the issue. I have dealt with many of these issues. Old cars really are fractals of problems. The more you fix the more you discover there is to fix.

      Welp, you've got a long list of experiences right there. I'd say you're on the right path.

      That's correct, suits my requirements a bit better. Sure there are also numpties there, however it's generally a different vibe and more my kind of vibe.
