We don't modify many OE diff centres anymore mainly because the jap LSD's are now very well priced.
However, if a customer feels the aftermarket units are a little aggressive for everyday use, we will do one to suit.
The A-LSD units can be a problem. There is NO room for more clutches, which limits its LS torque capability.
So V-spec cars that make a lot of grip usually end up with a mechanical LSD in them.

Really?
Racepace did mine years and years ago now. Before i pulled my car off for the RB26 motor conversion.
The diff did approx 12,000km's (9-10 months) which included lots of burnouts @ the drags as i was racing every 2nd or 3rd week
Lots of dyno work, street duties any anything else you car to think of.
Certainly worked ok if you ask me
We dont just shim it, Ash.....
We re-machine it, add more clutch plates (most important) and then reshim... they then work really well and last.....
cheers

I'd call a fairly good result....only 1.25bar, DTS 4wd dyno, (DTS dyno ie. non shootout, DD shoot always gives a nicer number), and looks like the attessa is chasing the front wheel speed a little, causing the bumps. Drive it and see how it performs...........
-
R34GTT Neo VCT is simply switched just like the earlier R33 RB25. No it is not infinitely variable...I wish...
The VCT gear is different tho and does seem to "switch" on-off more gently than the earlier versions, giving a nicer transition. But we have tested and they are definitely only on-off....
cheers.

mine has a 3" exaust and it does not cause me any issues.. i am looking for around 320 - 350rwkw
Power curve is looking nice.
See how it goes as you wind up the boost.
When you have 350rwkw and NO knock, let us know...........

The Standard RB25 inlet manifold is fine, very good even! We have RB30/25's with GT3540 .82 making 350kw @ wheels on 20 psi pump gas no problem. Power peaks at around 7000rpm and hangs on nicely. The gains are to be had on the exhaust side. 3" aint gonna cut it at those power levels. A lot of GTST guys run into trouble as they slowly upgrade. Bigger injectors, bigger turbo, 3 litre bottom end, all supported by bolt ons (intercooler, exhaust etc) only ever intended to make 200-250kw. Check the VCT is working correctly and the cam timing is correct also.
Cheers.

Just a note...
The GT-SS specs you listed are in fact SR20 Gt-SS specs..
The GTR specific Gt-SS are quite a bit smaller ...much more like R34 N1 or -7 Garretts.
cheers,
Ben
The GT28060R-5's are nearly identical to the HKS GT2530's.I would personally go the Garrett if i were comparing the two.
Listed are the HKS GTSS specs also which uses the same turbine as the GT2530's but slightly smaller compressor wheel although the GT2530's much like the GT2860R's turbines are usually clipped to increase exhaust flow.

All RB cams are easy to snap regardless of brand. A little care and attention when installing is all that is needed. Get your installer to replace the cam FOC, and I bet he will never snap another.....

Turned out to be a great afternoon at Sandown!...........JFK and Jack went at it together for several sessions of 3 really hot, nose to tail laps. The times tumbled throughout the day with JFK finishing on FTD 1:18.4, and Jack an amazing P2. 1:18.7 (PB by nearly 3 secs!!)......Was awesome to see/hear them driving the wheels off 2 very evenly matched cars.

Pics would be great,

Thanks dude,
but we don't need turbs, ex manifolds, dumps, afms.....but just about everything else is required!!

Still looking.....

Superb demonstration of detonation!! Best get it looked at or it will be new engine time very shortly......

If you are only after 280-300kw@wheels, go GT-SS or Garrett -7's. Normal PFC, std afm's, std injectors, std air box, std fuel pump, adj. cam gears, std dumps, front pipes and decent exhaust. Get a good tuner and it will drive/start/idle like stock (surprise!!), but go like 300kw should. IMO, one of the best street set-ups, and only requires an ecu and exhaust change and she will pass epa..
-
Require all the twin turbo piping, AFM rubber hoses, GTR intercooler, intercooler hosing, oil/water lines, bovs, return pipes, etc.
We are returning a single turbo car back to TT, so need everything except turbos, manifolds,dumps, AFM's and pods!
