good stuff. post up the graph?

Thought about cam gears, but I like the fat low-mid range and am not really chasing peak power. Not sure if they'd make much difference for what I'm after.

Yeah, it was Stu (and friend) who installed all the parts, and did the tune.

He did an awesome job, and is a top bloke as well. I couldn't thank him enough.

Hey Guys,

i got my 260 tuned the other day after running it in after the rebuild.

Basics of the work, full forged internals, sump and rocker baffles, oil restrictor, Sard Injectors, malpassi fuel reg, in tank walbro feeding 2 litre swirl tank then to 044 bosch external, Garrett 2860rs-5 turbos, ems 8860 computer running 20psi it made 420rwhp (313rwkw)

Need to get a set of splitfires to increase the spark then we'll wind it up to 22psi and hopefully reach mid 320's at the wheels, that way completely ensuring it has 300awkw.

congrats on your newly acquired power. How much did you spent on total?

I was planning on the same mod myself but i have to scrap it cos im being restationed overseas. Will have to wait till i get back in oz.

How does the Jim berry's clutch feel? Any hard slamming like a sledge hammer?

Yudy

Very nice work Grim. How did you manage the rwkw figure? (front driveshaft out?)

Jim Berry clutch is a rebuilt factory item. Slightly shorter travel than standard but really smooth (wife can easily drive it).

Nice work guys. It inspires me to begin the mods to mine :)

How do you find the GT-SSs? Not too laggy?

From my knowledge, the GTSS is just right for it. Probably you are refering to the GTRS. That will be too laggy.

Yeah I know the GTRS is laggy as all hell, but the GT-SSs are still going to be slightly laggy. I was wondering how they compare with stock turbos. I really wouldn't want much more lag than stock. The stockers can support another power for what I would want, it's just a shame the turbine wheels are ceramic, otherwise I'd keep them.

Hey Andy,

Yeah dropped the front shaft and pulled the fuses then ran it in rwd as my tuner only has a rwd dyno, waiting to sort a few things then will drop it back into 4wd, i must say, 313kw in rear wheel drive is ALOT of fun though, the "wow did you see that volvo go sideways" looks i get are pure GOLD! :D

Mine with the 2860rs's isnt too laggy, real boost starts to come on by 3500rpm, then acheives full boost by around 4200rpm, so it comes on fairly hard. Its even more fun when it hits peak torque around 6000rpm and breaks traction in all but 5th gear! lol!

GT-SS's feel like they spool up just as fast as the stockers. Don't have exact rpm numbers, but by seat of the pants they are very impressive. Almost feels like a big cube NA motor.

My old RB20 with 450hp bb turbo, had lag. These are light years ahead.

Do miss the sudden boost hit and manic wheel spin though, (damn ATESSA, sometimes i wish i had a switch to turn that off)

Hmm been reading this with interest as i went for the 2860-7's as i wanted the response (there the same as GT-SS??). I wanted 300rwkw with them, might get it. Mine's a built motor with cams, so hopefully be responsive. Will know shortly.

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
