im new to these forums so im asuming im in the right section if not could a mod move this thred to the right one. im from NS.com and they are aboubroad minded persone gurus with CA's and SR's but not very bright (IMO) on the RB25det motor and if i post this thred on NS they will tell me to come here and ask, so i thought il save abit of time and come here first.

*note these are all future plans as i am currently on my P's

and plan on having a reliable 300kw daily with a few track days every now and then, this thred is focusing on engine so dont tell me about driveline

RB25det (model undecided just know im not geting a neo)

z32 afm

power fc djetro

splitfire coil packs

fmic

discoe potatoe? t3/4?, GT35? or any other u might suggest for what i plan, dont care if its a high mount or a low mount turbo as the engine will be roughly a 2 year project itself (plan on putting engine in when off P's)

264 cams intake and exhaust

remove VCT (if it has it still on)

rods?

gasket?

700cc injectors

fuel pump and reg

oil pump and cooler

and 3'' turbo back

*is the stock throttle body worth boring out or am i beter of buy like a after market 80mm

cant realy think of anything else, i know im probly missing a shat load of parts but its 3am and cant realy think of anything else that i might need.

Welcome... The NS.Com guys are right to send you here...

I think you need to do a lot more searching/reading however, as basically there is nothing 'basic' that hasnt been covered or touched on in fairly good detail when it comes to RB25's and under 300rwkw.

Some threads to get you started

Also have a read of the Dyno Sticky in this section:

http://www.skylinesaustralia.com/forums/Rb...yno-t55845.html

End of the day however it think you should stick with the SR, as your Victorian so there is all sorts of legal issues you'll have to contend with the more you modify, the harder it is.

:) a RB owner telling me to go SR

the CA motor was engineered by nissan and the RB motor was designed off it or other way round cant remember

the SR motor is from a tractor (seriously)

and 300kw@w is a bare minimum i want from that motor and i want it as a daily so need to be bullet proof just not a shot in my pocket

Im Melb also, and im well across legalities after my many different conversions, setups and so on.

SR is simply easier to keep on the street.

Either way, do what you want, ive linked you to the threads you need to read on the topic.

You just need to come up with the $25,000 to get it done now.

Z32 + D jetro doesnt work because djetro is speed density (MAFless) and you will need to use a rb26dett PFC djetro if your gonna go that way as there are no rb25 ones.

if 300rwkw is a bare minimum than budget for a full rebuild, cams arnt necessary.

and to be honest if you deadset on a RB conversion id just go straight to the RB26 as it would be cheaper in the long run to get the power your after.

Nismoid.... just wondering, what are the legality issues regarding a rb26DETT (from a 33GTR) into a 33 GTSt. Is it ok if the motor is newer than the age of the body its going into or do you need engineering certificates?

Was discussing this with my mate the other day but neither of us was sure

300kw with reliability from an SR Ash, we all know thats going to be pretty street un-friendly, track un-friendly and pocket draining.

Why would you want more than 300 anyway? In a pissy little Silvia its heaps of power. Especially for drift if thats what you mean about track days.

A Standard RB25 with cams and a 3071R would be plenty. You dont need a huge peak figure, midrange is what you want for street and drift.

Be a man and go the conversion, maybe consider an Engineers Certificate, if you dont have the money prepare for the car to be taken off the road.

Ive got a RB26 in my HR31 - its very easy, easier in a GTS-t actually than my car (due to brakes, gearboxes etc etc, all of which i have upgraded, but if i didnt it would have been a no-no).

RB26 for a R33 is a good choice, but not one for the person on a budget... RB26's cost money if you chase power, same as RB25's i guess but to keep a RB26 legal-ish and chase power is far easier hence you can make more and overall costs more :)

Making 300kw+ from an rb with mods like an aftermarket ecu, fuel system, gt35, cams, coils ect,ect is a walk in the park throw in a set of rods and pistons and it becomes relaible, honestly though if i only wanted 'street' power i wouldn't want any more than say 250rwkw it is plenty for the street..

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
