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!

Top stuff, nice to see someone pushing it & sharing setup/results for a change :devil:

send me the 26 ecu and i will set it up so it plugs in and fires up straight away.

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

to true ^^^

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:

What's the turbo kit worth?

yeah new i sell them for $4900.

ABU... buy ROYS, honestley this R31 with the L2 is the BEST rb20 i have ever driven........ and one of the most fun cars ive driven full stop.

send me the 26 ecu and i will set it up so it plugs in and fires up straight away.

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

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:

Do I have to buy MAP sensors separately or they are included with D-jetro vers. of RB26 power fc ?
they are all separate but i can supply the whole lot.

trent, have I ever told you you are a very attractive man. :down:

always enjoy your threads mate.

you have inspired me to put some cams in your old car to keep up with these RB20 buggers. :P

    • A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway. 
    • Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).
    • I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as 
    • Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement
    • This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too
