Gday all,

A real quickie here, just wondering if anyone knows what power an RB20DET, pref out of an R32 GTST, makes at the wheels - when she's completely STOCK STANDARD...

I've just the below mods done to my baby and she now puts out a tidy 166.3 rwkw running 1.0 bar boost. :(

Apexi power FC

Greddy Profec B elec boost cont.

3" turbo back exhaust (catco hi-flo cat & dump pipe, X-force cannon muffler)

600x300x76 FMIC with full custom plumbing

HKS pod filter in FL guard - best cold air intake i've ever seen!

Sard adj fuel pressure regulator

Walbro 550hp 250 lph in-tank fuel pump

stock injectors - about 80% duty cycle i think...

Unfortunatley I didn't get the chance to dyno it beforehand so i'm interested to find out what the power difference is. I'm guestimating they make around 100 - 110 rwkw but if anyone's actually dynoed a stocker, i'd love to here what they really make!

Cheers

Why such low power figures?

Is your car 1989, or does it have a series 1 rb20 in it??

Those mods should see atleast 180rwkw, if not more...

Stock standard ive seen one dyno at 104rwkw to help you out!

Yeah the bloke at Unique Auto Sports says those mods should see 170 - 180 rwkw, but then he said that i am only running 14psi plus its a stock turbo...hmmm. I've got to back and see him for a few tuning tweaks and i need to double check the injectors so i'll see if there's any difference then...

104rwkw - cheers!

Ye... you could run 1 bar (0.7psi more) but wud of thought u wud of got more.

Maybe u have a series 1 turbo, these are a fair bit weaker and have different inlet manifolds too!

No stress... bigger turbo time :( Esp with those supportin mods!

Why would you have thought he would make more power?

As for different manifolds and differences in turbos, Series I and Seies II R32s :confused:

From what i would have gathered, 166rwkws is on the money:)

Meant engines dude! Not the actual car... lol

From what ive seen those mods WITHOUT a power FC can make up to 250rwhp... hes got that ontop..

Im yet to see a std turbo R32 GTST make 250rwhp, big thing with the Pfc is that the power curve/tractability of the engine should be improved...the turbo can only flow what it can flow, but the Pfc can help improve mixtures and response.

Another thing, i dont know how true this is as its just an observation, but the R32 ECUs appear to be far more flexible then the later R33s which insist on doing silly things with fuelling and ignition when you wind up the boost with a few breathing mods.

The R32 on the other hand does a pretty good job of adjusting to the new airflow requirements of the engine....

lol...That said, does the car drive any different with the tuned PFC now:)

Bigger turbo time = nothing makes me more moist!!!! :aroused:

in time an HKS GT RS will grace my exhaust manifold...

mines a 1992 build so its definitely a series 2 engine & turbo...very odd that the power figures are less than what others are gettin with similar / less mods

also i am running quite wide rear wheels & tyres - 9" wheels, 255 tyres - would that affect dyno figures?

No stress... bigger turbo time :P Esp with those supportin mods!

I had mine when it was bog stock standard on 2 different dyno dynamic dyno's.

D&T Performance - 113rwkw (hot day 98RON BP Ultimate)

RPM Performance - 115rwkw (cool day, 95RON BP Premium)

Check out some of the dyno run scans on the D&T Performance website.

It gives you an idea how the stocker rb compares to the ls1's, 200sx's etc.

I later had mine on the RPM Performance dyno, ran 1bar with a FMIC, 3" Turbo back exhaust, a little bit of extra ignition timing and fuel leaned out slightly via fuel reg modification. It made 164rwkw.

A turbo can only flow so much air before it begins dropping efficiency.

This is why RB20 turbo's tend to drop boost UNLESS you run a good ebc that can vary the duty cycle at higher rpm. (AVCR or Blitz SBC-ID)

With 1bar holding to the redline it should be up around 170rwkw, and maaaybe 175rwkw if its a cool day. It all depends on the tune, how rich it is running and how agressive the tune is (ignition timing)

this is strange my car with front mount. 12PSI and zaust has 141 KW at the wheels. i am sure u should get more then 166KW. maybe something worng with his dyno. The Power FC should atleast give u 20 - 30 KW on its own

i just wish ppl would stop comparing their dyno results to someone who has dyno'd their car on a different dyno in a different state. workshops can make a dyno read as high or low as they want it to. run it down the strip, at least that gives you a better indication of how quick your car is imo.

    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
    • The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.
    • Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
    • Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
