they reach max power at 6600rpm... so i guess there is no point taking it past that

the n/a rb30 power steering fits up.. just

why not post the wiring loom up on the web for all of us?? that would be a big help

hey boys i'm in the middle of finshing up my rb20det conversion does anyone know how to wire it all up in syd i'm very tight on cash but if anyone in syd on here wants to do it i'll be willing to pay you.but yes any help would be nice.

For some ppl who wanted to know last month I raced my car over the 1/8th(200m)mile , NOT 1/4(400m) I pulled off a 10.134@63.38MPH with 3"exhaust, CAI, and 14psi also the car has 4.11 gears and a minispool I will be goin out this weekend again to see if I can better it with the headlight removed and 20 deg of timing

I would imagine that it' would be a very similar process needed to fit a RB25DET. Am I right? Would be nice to know.

I doubt there would be much difference at all

The rb20 unit will not work mmmm beg 2 differ, run cold air retard timing a little and 12 pond up here running bp ultimate and she never pinged and she wasn't slow! just my experence! just didn't have the founds to put a front mount on at the time! just got 2 90 diagree bends and welded them together! didn't have much lag :P

Hey, Im currently doing a Rb20det conversion on my vl. I've helped mates do these b4. Im having trouble setting up my power steering pump! Can you help? Chalkie.

Sure can mate, its verry simple, remover the powersteering unit the RB20 comes with and simply replace it with the RB30 unit, bolt it up (it will just fit) put the rb30 p/s belt on and your powersteering will work fine The reason why we dont use the RB20 unit is they are a dual stage pump where the RB30 uses a single stage pump

hey fellas, i wanna do a similar conversion but with an rb25 det. why cant you use the rb25 ecu? also will the wiring between the rb25 and rb30 be similar to that of the rb20 to rb 30? wiring is the only thing i am worried about at this stage.

u can get kits, look on the internet u would use the rb25 ecu with the rb25, the only thing u have to wire up is the ignition etc to the ecu, so that car will start and power the computer, same as u would have to do with any conversion! hunt around and u will find it, i believe www.justjapautomotive.com (http://www.justjapautomotive.com) will sell u the wiring loom diagram for around $150-$200

i have done the rb20 conversion on my vl and its not as complex as your saying. i didn't have to change over any of the things you say. for all the sensors just wire them up properly from the ecu. i didn't change any of them. all the rb gearboxes are the same(except the 4wd ones) the gearboxs are just gear out differently, on a standard vl diff the rb20 gearbox puts the speedo out by 20kmph(4.11 fix this) i've gone through a couple of rb30 boxes and a rb20 box and they swap straight over, no physical difference, and rb25 boxs will bolt straight on also. clutchs are exactly the same too. with the rb20 powersteering pump just block off one of the lines or join them both together. it works fine. aircon works fine also with the rb20 one. if you change the harmonic ballancer the altenator will be out of alignment with the belt, hence you will go throught a belt a week. just leave the rb20 one on there. apart from doing a service, waterpump(which by the way is the same as a vl one) and timing belt. you don't have to change anything. just hook it all up. and if you have all the gear there and auto to manual conversion is easy too. i did my conversion in a day. really the hardest part is the wiring, but even thats not to hard with all the diagrams. this conversion is very easy to do.

just a question what computer r you's using cause i want to do this conversion on my vk

so no-one on here has a wiring diagram for an rb20det?? why wouldnt ya just post it up and help out a few lads.

the shifter is the same on the rb series of gearbox (not 30t). is the sr20 the same? now it looks identical (photos on net), but i dont want to buy one to find out it wont bolt up......
