Top RB20 Club... do you have over 260rwkw?

[carl h]

some one needs cams.......

[Jago]

someone also needs allot of money

sponsorship anyone?

Anyway, full boost hits at around 6000-6500rpm

hot damn, some one really needs cams .

[1400r]

182 rwkw and full boost at 6,500 I know of a t88 32 rb24 with the same response and 320rwkw

seems like the twins were a waste of time?

you could have made 180 with a rb25 turbo?

[DRFTD_32]

anyway, put my RB20DETT R31 2 door on the dyno, for a full tune and bumping up the boost.

Got 182rwkw @ 7000rpm on 13psi of boost in 5th gear. Dyno wasn't a dyno dynamics and this dyno was known to read lower than dyno dynamics dynos so meh.

<{POST_SNAPBACK}>

Damn that is a cool sounding setup...

Do you have any pic's?

[FATGTS-R]

Well the GTSR recorded its highest ever figure yesterday arvo on the dyno.

Last tune made 235rwkw @ 16psi, graph is somewhere in this thread lol.

Had some ignition dramas and as I found out a blocked cat so a magic cat was thrown on along with a different ignion setup and they dialled in 22psi to see what it would do and it spat out 283rwkw. When I pick it up I will post the new graph.

[Roy]

That is awesome...its good to see the thing turn a good number after having put so much blood sweat and tears into it.

Are you planning on running that sort of boost? I recall talk that your engine had been opened and tweaked...? Personally based on all the hard work and coin you have thrown at it i would enjoy the thing at 18psi for the next 6 months

Again congrats!!

[yogi000]

nice work!

[Cubes]

Very Nice indeed.

[FATGTS-R]

What lies inside the engine is still an unknown quantity. It was supposedly an RB24 but the stroke is still as per factory.

A few mechanics have commented it has the "forged piston rattle" on cold start but the car is 19 years old so god knows whats rattling lol. Time will tell whats inside, hopefully not soon though...

And I will definately be pulling out some pressure. The gearbox was whining already so I dare say one run through third gear will result in failure.

[Jago]

very nice figure indeed, is it an original GTSR?

as for it being a waste of time(my TT setup), no i don't think it is, i think it could have some potential.

As for pics, engine bay pic is in my signature

and that's the car at the SAU xmas party

[FATGTS-R]

Yes it is an original GTSR.

Mods: 3 inch exhaust , A/M Ecu, Injectors, fuel pump, remote mounted falcon coil pack and thats about it.

Everything else i.e turbo, extractors and cooler is still factory.

[Jago]

get fked, no way they are factory, or are they?

[Bunky_r31]

gtsr came standard with front mount cooler stainless steel (bunch o bananas) manifold and i think a t04 turbo

hence the big figures

awesome results, and rare as car

i'm still to crack 200rwkw but i'm workin on it:)

That is so cool that the thing has finally punched out numbers....and considering it was a little more responsive then mine from memory, well that awesome

What did you end up doing for a dump pipe, as from what i have seen the std rear housings are difficult things to work on?!?!?

[kwazza11]

very nice fat-gtsr. what after market ecu are you using? i take it its not a pfc from the lack of afm? no porting or cams?

how did you measure the stroke without removing the head? verniers down the plug hole? could be just an rb20 crank with 82mm pistons?

and your right about the box. i'd be looking at a rb25 one very shortly. either that or use 205 tyres on the rear MAX.

my rb20 box has just about destroyed its main shaft bearings again with only 220rwkw.

Roy, I am yet to do anything with the dump as I dont know what to do myself!

The Ex group A racers are coming for a historics meet at the island in a few weeks so I am going along to try and have a peek at what they did on those things.

Kwazza, ecu is Autronic and no porting has been done. Cams are unknown but possibly factory as previous runs have made max power at 6,000-6,100rpm.

How was the stroke checked? No idea, I can ask the mech but no the head did not come off.

Didnt finish work in time today so will be picking it up tomorrow morning and will put up the graph.

[Roy]

If you like when im back in Melbourne we can go araound and have a look at the Grp A car of my friend , though i wouldnt be surprised if the rear housing is a bit different to what the road cars came with...i know he went to a lot of troubel and expense, and help from the right ppl to get a new version of the turbo the car use to run
