Ok so i took the car for a run yesterday and thought it was off the show (not able to keep it straight and just lighting up the rears) anyway i dont have my boost gauge yet and wasn't 100% sure what it was running. Figured it to be around 12 -14psi so i borrowed Griffo's boost gauge and "BOY" was i off.

The little old RB20 was boosting at slightly over 1.5 bar.

So we turned the boost back to 1bar and is MUCH better, still very easy to loose the rear end from time to time, just have to moderate it with the right foot.

Im going for 240rwk's once i get the FMIC on an exhaust but i think TimmyB can back me up on this as i think i have one of the toughest sounding cars getting around on Tassie roads

Pics to come guys.

240rwkw from an rb20 with fmic and exhaust??? dont you mean 140....even 140 is a good effort, an rb20 is lucky to reel out over 100rwkw. and if you dont have an exhaust...how does your car sound tough??? does the car have any other mods??

Sorry guys was in a bit of a rush when i posted this yesterday. Realised i had posted it in the wrong section and then reposted it in here. Just realised though that i cut over half the original post off.

Hope this helps to clear it up a little now.

Car mods as follows:

TD-06 turbo with external waste gate (50MM i believe)

bigger injectors (with extra injector for high boost)

GReddy injector equaliser control (is what i've been told it is)

aftermarket ECU

electronic boost controller

upgraded fuel pump and swirl pot

adjustable fuel regulator

Z32 AFM

GReddy BOV (currently venting to atmosphere

GTR intercooler (replacing stock intercooler) want a FMIC

3' dump from the turbo into rear muffler which is standard at the moment, with extractors.

GTR rotors and calipers (is what i've been told)

irridium plugs and upgraded ignition coils

rods and pistons have been done as well as bearings (is what i was told)

set of race springs and HKS front and rear strut brace.

Apexi air intake with modded CAI /Heat shielding (thanks to SAU thread)

button racing clutch and locked diff (want to change diff)

Have not dyno'd the car yet as im still getting it on the road and everything sorted out. When i do i'll let you know how it goes.

Talking to the tuner yesterday and he said if didn't have a couple of hundred kilowats after driving it he said he would eat his hat

Can not wait to get it on the road although i have been re thinking it as a daily driver now!!!

I'm more interested to know why you decided to post this dribble in more than 1 section.

You haven't given any details or asked any questions. Whats the point?

As mentioned above i cut over half the post off after realising it was in the wrong section. Sorry to dribble BHDave, wont let it happen again :cuddle:

My question are:

other people with similar mods just wondering what kinda or power your putting out and how have you got the car tuned?

What is it like on fuel? ( as this is my daily driver)

Any tips on suspension set up and what tyres are people running?

I have other questions but iahve been told that i dribble on so dont want to get anyone's back up at all.

Cheers GMB

You better not :chairshot

Now 1.5 bar without exploding seems plausible.

Im guessing you have one of the original style td06 highmount kits with the extra injector mounts in the cross over pipe. Nice one.

Should easily be capable of 200rwkw plus, closer to 250rwkw actually.

Yeah tell me about it. As i only really just picked the car up (after importing it from Japan) it appeared to be running high boost.

As the boost gauge didn't work (split line from the joiner under the hood) i didn't know what it was running althought figured it around 12-13psi, but after hooking up my tuner's boost gauge it was actually boosting at slightly just over 1.5bar.

Yeah i got one of the original TD-06 high mount set up's with extra injector. (can see in pics)

My tuner recon's 240rwkw's should be pretty easy once we know what the car is doing.

Im still confused, u have all these mods, and dont have a boost guage?  wouldnt u think to put a boost guage on before slapping cash on other mods. ?  It can you know, be sorta handy ...

All the gauges that came with the car dont work. As i have only had the car for a couple of days im slowly working everything out.

As for slapping cash at other mods, the car came like imported from Japan. The only money i have spent is purchasing the car and importing it.

As for smart arsed remarks like that, keep them out of my posts. You got something like that to say, PM me. For any other advice/comments or questions then post away.

a GTR intercooler IS a FMIC...

:confused:

you've had all this work but it hasn't been on the dyno?

something doesn't sound right...

or did you buy the car already modded?

The GTR cooler is where the original intercooler is normally situated. It has been modified slightly to fit.

I will be buying a new FMIC when i can find either a kit or a good price on the cooler and piping.

So if you have the heads up then let me know.

WazR32GTSt i have bought the car as is from Japan, so all work done was buy the previous owner/s from over there. Im trying to get some info on everything on/in the car so when it comes time to tune and dyno then it will make life a little easier.

well the GTR cooler is normally quite a large unit, not sure how it would fit in the side of the front bar even with extensive modifications. must be a tight fit!

you could pick up a FMIC in the group buy section for like $300 i think. go have a look. or keep your eyes out in the for sale part...

the hardest part is piping. my suggestion would be to get an exhaust shop to custom-make you some pipes. works out the cheapest (if you are on a budget). if you aren't on a budget then check out www.modyourcar.com.au i think they have piping kits there...

oh, now i see

you should have said at the start of the thread that the car just came from japan!

i think we just asumed that you did the modifications yourself

yeah these cars can be a mystery sometimes with what has actually been done to them when they arrive.

it seems a bit of a coencidence that ALL gauges aren't working... including the stock ones?

if just the aftermarket ones maybe they were unplugged? or all linked somehow? i don't know.. maybe someone pulled a fuse? i'm not much of a gauge expert...

i hope you can manage 250rwkw will be nice to see the 'ol rb20 pull some nice figures

:(

yeah i would prefer to buy a kit that included everything, then there is no messing around. Been looking around and i think the cheapest i can find one is a R32 Hybrid copy kit with piping and clamps for $650 plus shipping.

Or i can buy the same core for $299 then piping???

Either way i'll look into it.

The intercooler is an extremly tight fit at the moment and thats why i want to sort that out asap.

Yeah sorry about the mixed post. I left so much out when i realised it was in the wrong area. :chairshot

omg that's a tiny rear muffler... what size is the exhaust??

i would attend to that too if i were you...

:(

BWAHAHAHAA yeah its the stock muffler it appears at the rear.

Exhaust is 3" off the turbo then into the stock system. As previously mentioned it has the extractors set up on it and the external waste gate.

Want to look into an exhaust but very expensive in Tassie. :crazy:

      Stagea Front CV Axle Question

      By dbm7 · Posted

      Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents

      Stagea Front CV Axle Question

      By Duncan · Posted

      I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.

      Stagea Front CV Axle Question

      By soviet_merlin · Posted

      One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?

      Stagea Front CV Axle Question

      By S1_C34 · Posted

      I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.

      Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
