Used this to try a quick theory i had regarding d-jetro and other rb engines so i fired one up on a R33 first then fiinally fitted it up into this R31.

Std Rb20

Rx7 injectors

Thai plenum

Trust TD06-l2 -20g (2 litre nirvana)

rb26 d jetro

277rwkw @1.2bar

408Nm@6100

Real nice car to drive, lots of usuable power and screams like crazy over 4500 and has phenomenaly strong mid and top... will interesting to see it lap winton this weekend,

Nice work uras, as a matter of interest, in reference to your first post. what was/is your theory regarding the Djetro.

Hey, URAS, can you tell me via PM about the modifications needed to run rb26 on rb25 and or rb20 ? I'm not in australia. So no intention to harm ur bussiness. I'm just having the dilema which way to go. rb26 PFC are way cheaper than rb25 new one. Is there a big difference in basic maps ? Like would rb25 start up with rb26 d-jetro with minor changes to inj. cc size and something else ? or ? If it possible of course ! Thanks!

When you say std RB20, do you mean it was rebuilt to standard specs? or just as is completely standard with just turbo, injectors and plenum? Obviously there are other accessories like catch cans/oil coolers and what-not, but they are more reliability accessories.

this engine has never been opened it is a wrecker special.

LOL, wrecker special :rofl:

This is the 3rd std RB20 with this turbo setup making about the same power, the other two have plenty of kms under their belts with plenty of drift, track and motorkhana work to prove they are reliable at this power. I expect this setup will continue the trend :D

New the kits are worth between $4500 up to $7,000. I think it depends on where you buy them and who from. Second hand if you find a full kit then they are usually about/under 3k with all the piping etc.

I am considering selling mine is for sale as my car is getting parted out in preparation for Track R32 EVO II :/ Sad news is it will be off the road for a long time :wave:

Hey, Trent, whats the difference in tunning the D-jetro ? Will I be able to tune it myself like the normal L-jetro ? Also is there a way to make it work for rb20 and rb25 ? LOL.

I guess its even easier with MAP, you wouldn't have to make changes to the airflow correction etc.

What about the O2 sensor ? Will be able to use stock sensor ?

What about fuel economy ? Can I achieve the same fuel economy as with MAF and 02 closed loop ?

And the last, but not least: turn around time. How long would it take you to make all the necessary changes ? And how much money are we talking about for doing that job ?

Also if I send power fc without controller, its alright, right ?

Thanks!

Let me know here or pm.

P.S.

Do I have to buy MAP sensors separately or they are included with D-jetro vers. of RB26 power fc ?

The only differerence is the way the cursor traces through the maps, tuning is the same, RB20 and RB25 is no issue..... vg30 is also no drama :)

i guess its even easier with MAP, you wouldn't have to make changes to the airflow correction etc.

i really prefer to get my fueling tables spot on instead of using the arflow % adjusters but on some problem cars it can be handly for hunting idles etc... all things you need not worry about with the d-jetro

What about the O2 sensor ? Will be able to use stock sensor ?

What about fuel economy ? Can I achieve the same fuel economy as with MAF and 02 closed loop ?

yes it still has o2 feedback (closed loop) but honestley you can tune them up good enough not to have to use it.

And the last, but not least: turn around time. How long would it take you to make all the necessary changes ? And how much money are we talking about for doing that job ?

i usually only do it as a drive in drive out operation but i can modify the the internal plug to suit either rb20 or rb25. Pm me for pricing.

Also if I send power fc without controller, its alright, right ?

yeah i dont use the hand controllers anyway, fc datalogit ftw :huh:

they are all separate but i can supply the whole lot.

      Stagea Front CV Axle Question

      By soviet_merlin · Posted

      Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...

      Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.

      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

      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.

      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?
