I am pretty sure that 25 neo's can only do 195-205rwkw max from stock turbo.

Thats 261.50-274.90rwhp.

how is an older less powerfull rb25 going to put out more power with fewer mods?

it isnt, stop talking shit.

or point me in the direction of threads of people posting dyno sheets to show otherwise.

well to prove that my one is truthful here is the dyno sheet!!! 302rwhp!!!

here's a standard turbo running 7psi , standard spec rebuilt motor with a HKS 264 deg exhaust cam set at '0' deg. It has a S-afc and factory ecu, large bosch fuel pump (from when the motor ran nitrous). Runs a turbo back exhaust and factory intercooler.

The rich mixtures are due to the fact that I was selling it to someone and I wanted it to be reliable from the get go. He was also not yet used to the power so the very mild tune was to keep him alive long enough to allow him to re-tune.

The change to the exhaust cam took away the 'bump' even without the ecu upgrade.

This car wherever it is could easily be tuned to run walk in the park high 12's even without a decent launch.

Another example of how good the factory turbo is can be found in 2rismo's car, even without my old nitrous kit he was able to run into the 12's. With the kit switched on he runs 11's.

Pulp i dont know how it pulled that much

1st run Mods 3, mandral bent exhaust from turbo back and hfc

cypher pod fillter

Psi in wangara first run 242rwhp 10 psi

they spun out there was another customer there and he said i was pulling more than his r33 and he had piggy back ecu and frontmount + my mods and it was manual

2nd xspeed after front mount and eboost 240rwhp at 8psi and then 250 and 10psi

i told them about psi effort and they said psis dyno would have been stuffed then my baby busted out the 250rwhp

the turbo looks stock and i have not touched the it but i was told it MUST have been hiflowed to pull that power

i have all ways kept it serviced by the same mechanic

That dyno printout that Wildcat posted is of my car..... And as far as we are aware its still got the stock ECU, with just the piggy backed AVC-R to control the boost and a SAFC-II to control air/fuel mixtures... the timing and air/fuel was played around with and at some times the curve did smooth out a bit but it cost HP up the top end.... The curve might not look as smooth as the other one you posted but I dont find it a problem at all when driving....

its one thing to be able to make the power its another not to have too much knock and blow shit up in the car.. my r34 gtt made 297rwhp but had to be put a lil down to 268hp cuz my engin was knockin way too much and i have a very hevy foot.plus i would hait not to have a reliable car.. but gettin 319 outa a stock r33 sounds very sus as i have got a 3.5inch exohst all the way, fule regulator, pfc, ebc, pot filter,fmic and a few more mods to be able to make that power but i still need engin internals to be able to take push it a lil more.. i cant picture how a gtst r33 can make more than an r34 with less mods!! and the r34s have Veriable Valve timeing too wich should add some edge.. i agree with noise. newer car means better engin although the ciramic turbo in the r34s limts us to max of 15psi our engins start knockin alot at about 13psi with 98octane fule that is how ever the car u guys were talkin about doesnt have a pfc do u probebly dont know howmuch knockin u gettin unless ur usein a dig tool for it..

s2 33 has vvt also, not sure if s1 do.

friends ex r33 made well over 350 rwhp on stock internals, and for more then a week. 320 is a walk in the park.

13psi causes me motor to knock does it? is that 13 psi with a stock turbo? a gt30r? t88? because they all flow the equal same amount of air at 13psi....

a stock 34 turbo is out of puff before a 33 one. dont forget that.

dude if your engines start knocking at only 13 psi something is very wrong hey and as long as they're tuned right, the stock rb's can make very decent hp on standard internals

if i had those mods and i had knocking at 13psi i'd fire my tuner asap

No way in hell its making that sort of power with totally stock bits

cams, headwork ?

maybe more capacity ?

what sort of correction on the dyno?

is the dyno currently dyno dynamics accredited?

No Cams or headwork that we know of. Definitly standard capacity as NIB said the car looks like it has never been touched.

Has been running with the stated mods for more than 2years now at the same boost level and never had any engine troubles so reliable??? HELL YEAH... I guess we can all just say that this car is just a freak or posible hi flow turbo?? We wont know until we pull it apart I guess...

2rismo uses nos to make his power :thumbsup: CHEATER! :D

What time has this 33 set with 320 (sAfrican American) rwhp

thats got to be mid 12 with good mph....

runs 12's without nitrous tho' on the stocker turbo.......

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
