I've seen over 300rwkw from a stock bottom end R33 with GT-RS and cams.  There is a thread on it somewhere here.

can anyone link to this thread? i cant find it via search. OVER 300rwkw from a GTRS is a very big ask, i will believe it only when i see the dyno graph! Thats over 500hp at the engine from a 400ps rated turbo. even with a conservative rating thats still a big ask!

well i quess you have your dyno reasults and it was in fast fours as i said But with people on the forum only making 360-390rwkws with two on a gtr :(

So if I go to the GT-RS (more than likely) what should be considered while the turbo is being done ??

GT-RS turbo

Dump pipe (HKS Extension pipe)

Tomei Poncams (264s?)

Fuel Pump

Injectors (Blitz seem to be the only direct fits i can find)

Headgasket (Tomei 1.6/1.8mm)

Oil Cooler

Splitfire Coils

adjustable cam gears ?

Z32 afm ?

can't seem to think of anything else.

nope the 33 greddy plenum doesnt fit the neo......you either need an adapter plate which is almost impossible to get a hold of or drill new threads in the cylinder head to make the 33 one fit. The second option is not one I would like to take....so im still searching for that elusive adapter plate.

Correct on the Greddy plenum... I also investigated this and found the same information. The stock plenum works fine though up to about 600hp, it just doesn't look as cool as the greddy plenum :lol:

hahha your car will be right if you just run 0.6 bar of boost ie stock boost. I have been to wakie many times with my car and have never had a problem. But I have heard of reports of 34s running stock turbo and running 0.8 bar or more and blowing up their turbos.

lol then i must have some kind of freak turbo because mine sees 0.9 Bar every time i drive it, and it's been fine at that boost level for over 18months, with a few track days too B) New HKS GT series turbo coming soon though :D

O/T guys but you could rate the GT-RS (esentially badge engineered Garrett GT2871R 52T with T3 flange and Skyline specific dump pattern) as ~ 420Hp compressor and 330 Hp turbine side . That exhaust housing is only .64ARR so 300Kw of exhaust flow ?

That GCG Hi Flow would be very cost effective particularly as you already have the R34 Neo type exhaust housing , one out one in and no orphan bits needed . Will look dead stock and is rebuildable . How easy is that .

Cheers A .

you going for an internal gate or an external ?

I think the Plazmaman one might fit the 34s.....as it uses the standard runners.

Just need to find out of the runners are the same on 34s are they are for 33s.

You'll need to find out if its chrome coated too... after all A/M plenums are more cosmetic than performance based unless your making something over what a stock motor is going to handle

:D

480cc will be pushing it @ 300rwkw.

Get the Nismo 550. Bolt it and gives you the required head room

stock boost on a 34gtt is 0.8-0.9 bar. provided it isnt pinging :D

I was lead to beleive its 0.6 or 0.7 ?

I turn it up to 0.9 when I feel like giving it a hit...

R31Nismoid: AFAIK nismo dont have 550cc for 34s.

I think next step up will be 740cc which is a little bit overkill.

Stock boost is 0.5 bar.

I have also never heard of 550cc Nismo injectors for the R34.

Not that I've done the calculations but I think 480's might be a bit small for 300rwkw too.

Are you sure you've got the right GT-RS there discopotato? That doesn't seem right based on what we are seeing on the dynos.

I thought the 0.64 turbine was the GTR one and the GTST was 0.8'ish.

Based on what I have seen HKS compressors seem capable of around 10% more than their rated capacity. So my feeling would be that the 420 bhp tops out around 460 bhp. That's 285 rwkw (using the usual 2wd Skylines losses of ~60 kw). It wouldn't take much of a "happy" dyno to read 300 rwkw.

:) cheers :D

Especially as the 300rwkw was on a dynojet dyno.

In "Ls1-land" we find the dynojet figures to be generally around 10-15% higher than dyno dynamics figures for the same mods.

    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.

    • Thanks buddy.. the standard one needs to be about another inch or inch and a half longer. Thanks anyway
