Hi,

The long and short of it is am after as much power as i can from an engine with only minor mods.

I have my heart set on an RB25 engine and was wondering what sort of power figure i would be looking at with the following mods :

Pod Filter

Intercooler

Exhaust

Boost controller : 12psi

Engine managment of some kind (remap/powerfc/emanage ultimate)

Thanks in advance.

Yeah it has to be a turbo back exhaust, then you would be looking at about 200rwkw...... hope your getting good tyres!

Pod filter wont do anything but sound kool, i am seriously considering going back to standard air box.... the pod is just a hot air filter! But I am addicted to the sound of induction....

have a search for some of the dyno days results on the threads in this forum but in general:

RB25 (non Neo)

pod (covered with an air feed)

exhaust (3" with good cat and split front/dump pipe)

intercooler

12psi boost

Power FC (with good tune)

=at least 200rwkw. (more likely 210-215)

If you want a quick and fun car you should focus on the mid range power instead of top range. Also remember even though RBs are better then SRs in general they cost more and cost more to mod/maintaine as they are 6cyl not 4 (eg. 6 spark plugs, 6 injectors, bigger intake manifold, etc...).

Also Apexi stop making the Power FC for the RB25. As the PFC was the best ecu (in comperison to the prices of other ecus) for basic mods you may need to spend more to get another ecu and tune (eg. Wolf).

Hi,

Thanks for the reply.

The cost is not an issue. The main thing is keeping it as stock as much as possible and achieving 200rwkw. If a PFC is not available, I will go the Emanage Ultimate.

If price is not an issue get a RB26. Stock makes close to 200rwkw for the R32 version and about 200rwkw for the R33. You wont be able to beat it for response as its twin turbos spool up quick and it has individual throttles. Plus a Power FC for a RB26 can be picked up for around $900 new. Its the ultimate Nissan engine. :-)

Very true, the Rb26 is an awesome engine, but engineers cert and insurance are factors in choosing the RB25, fairly easily engineered and insurance and happy with a 2.5 single turbo. You could hear the chicks voice crack when twin turbo was mentioned, "sorry sir we probably wouldn't cover that".

So the Rb25 is the next best thing.

U should have told her it came from an Aus delivered R32 GTR so its legal in Aus... lol...

Anyways good luck with the conversion. A RB25 in a light 180 would be a lot of fun. Just make sure u do some suspension mods and get fat rubber so u can keep the car under control.

Yeah, hopefully its lots of fun. Getting coilovers, etc, etc to cope with the weight and tyres and rims will be coming as well.

      Pops when backing off throttle, rough-ish sound through rev range.

      By Duncan · Posted

      It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....

      Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.

      Looking for a part number for this part here

      By Duncan · Posted

      So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

      Duncan's V37.......race car?

      By Duncan · Posted

      Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
