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.

    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
