Yeh more details about the busted boxes:) Mine is alive and kicking after 175,000kms with an upgraded clutch and for the last 25,000kms runs between 180-230rwkws depending the boost level im running. I certainly row thru the gears but i dont mash gears....

What is braking on them?

For a street car im starting to think perhaps a HKS 2510 is a good setup. On paper spool would be as good as std if not better considering ppls claims that a 2530 in only marginally more laggy then std. Second to that the thing flows better then a std turbo and you can run 1.0-1.2 bar all day. And you will go damn close to 200rwkws.

To me that is good healthy power in an R32. Only problem is if you start doing circuit work you may lomg for a bit more pull up top, lol just stick to tight tracks i suppose.

With around 190-200rwkws (was runing lower boost then usual due to a miss) i was still able to run a 13.4 @108mph with a slipping clutch. (Xtreme clutch doesnt like beign ridden hard off the line:() So i would think a 2510 is able to get you into the very high 12s...which is a quick car.

Oh and HKS 2510s are unloved meaning that i see them from time to time at very attractive prices, and at 200rwkws you are a good chance of being able to use std injectors with pressure reg, std AFM and re-mapped std ECU. The money you save on the injectors, PFC, AFM etc etc can be spent on some cams that can be bought new for $900, i then think you would have an RB20 that would upset the established thinking....an R32 with a nice and punchy 200-215rwkws:)

I havent ruled out going to a 2510 myself if i come across one, as im looking at getting the engine bay looking a little more std then at present...and i like the idea of running a std manifold with std heat shields etc, perhaps with the std manifold extrude honed and match poerted to the head:)

I love the shape of the 32 so there's no way I could go to the r33 (no offence 33 owners)

I think that 220-240 kw's on a rb25 in a 32 would be a perfect street setup that would also be good to drive on the track.

Even with my mates car which probably had 190 or so it pulled like crazy!!!!

Take it easy

heh, i agree man, the r32 is the king !

feels much more nimble to me than the r33s/r34s do.

Its just a shame the rb20 is so gay. Its like a honda engine heh.

Meh its not that bad, i mean my car only makes serious power at 6000rpm, like really starts moving then... it makes power before hand but its true power is really late in the rev range... and if i drop below 4500rpm... forget it... i have to add in a filthy clutch dump to keep the revs up there.

makaveli i would personally go for the rb25 (from a r33) and bolt up a HKS GT-RS turbo or GT2535. I did heaps of research and reading into these set-ups and eventually went the gt-rs. that will see you easily at 240rwkw on a lower boost setting, and the setup is perfect for street driving. you will also need a bigger fuel pump, it ends up getting costly.

well for the hp you want a near std rb26det could be and option worth every scent and if you buy half cut you cut sell all the bits you dont want awd box, panels ,lights ,bumber and you get a heep of bit you can use for upgrade or sell brake calipers,cooler etc sometimes it worth sending a bit more money at the start and you wouldn't have to buy the exacts you would with the other options to gain the same power. Worth a good think hehe LONG LIVE THE RB26DETT

Hi Guys,

thanks for all the input! If you have any more to discuss about experiences and the rb20 or rb25 please go for it I want to have a full picture before i go jumping into spending alot of $$$.

Thanks for the advice Croat, I already have a bosch 044 pump in my boot :cheers:

yes matts car sounds offensive.

I dont think you should bother with his suspension upgrades, they were quite serious... his car was a test pig pretty much, the work they did to it, they hadnt done before, and it cost a fair bit.

matt is happy with it though, he hasnt said anything that suggests he isnt happy... so it all works well... i've had a few drives, and its very very nice. (i'm assuming you know its setup for drift... therefore, no traction what so ever)

he is running a GT2530 with a dump pipe that has a screamer pipe attached, and a 3" system from there with no restrictions =) STRAIGHT THROUGH.

Hi Guy's,

I have finally decided that I am going to do the rb25 engine and gearbox conversion, along with a power fc and dump pipe.

I will do the turbo and injectors most likely early next year.

I was wondering where would be a good place to source all my parts???

I don't want to go some where dodgy and get shit quality parts, I live in Melbourne and I'd like to know what places would be good without charging too much.

thanks

Id be speakign to workshops re/costs before buying gear.

Quality workshops charge money, they are able to for good reason. Speak to as many workshops as possible, and visit them and discuss what you want, pricing and make sure a deadline is set, and its realistic.

If your paying someone to do it i think you will eb shocke dby how much it is going to cost.

Say 16 hrs to remove engine. Ppl will say less, but reality is thats what they will charge by the time they have degassed aircon, dumped fluids, unplugged harness and removed enginegearbox and tailshaft.

So then you need to pay for all the new fluids, new tailshaft, mod loom to either run without variable timing on the inlet cam or install R33 loom, with added expense of buying R33 loom. So thats more time. I wouldbe very surprised if a reputable shop would charge less then $3000.

Thats a guess, based on what i was charged to remove and re-install an RB20 by a Melb workshop earlier this year, plus the extras like tailshaft etc etc.

Very interested to hear sort of dollar figures you get quoted...as most the stuff on the forum is based around the prices of ppl doing things themselves or by friends. Good luck, shold be a punchy/good package:)

lol....scratch up another unloved RB20, another spare one if i blow mine:)

Hi Roy,

My mate Sam (Horus) spoke to Benny from Chasers and Benny will do everything

for $2,500. I just have to supply the parts. He has done conversions like this before

so I feel very confident in his work and know I will get a quality job.

take it easy

Mark

Nice choice mark,

you'll love the rb25 =)

Young Benny is doing it hey? haha hes a good kid.

If you have problems with ECU or something like that... you can run the RB20DET ECU with an RB25DET... you just have to run rb20 injectors and rb20 fuel rail and then you can run the rb20det loom with the rb25 engine. Tailshaft has to be shortened and balanced but it will all work sweet.

I'm sure i'll see your car at chasers, good luck with it man.

Cool, i have heard a few good reports now about Chasers, so good luck with it:)

And what happens to the variable valve timing on the RB25DET if you use the RB20 ECU? And last question, does the $2500 cover things like tailshafts etc etc, or is that included in your supplying parts?

Hi Roy,

I was told that $2,500 will do everything, although I have to go buy an engine, gearbox, loom and ecu.

I just got off the phone to my local mechanic whom I am mates with and have done all my mechanical work on my car to date, they told me $1,000 will do everything.

They will swap the engine, fit gearbox, fit the loom and ecu, put new irridium plugs, oil, oil filter, fuel filter etc... The will also shorten the tail shaft, fit my boost controller, catch can and dump pipe.

I think thats a good deal.

:cheers:

Also I just spoke to a mate that will supply me an engine for $2,500

provided that I trade in the rb20.

It is a 98 s2 r33 rb25 40th anniversary edition with 34,000k's

I can't wait I just have to pay my rego and then ill go visit the bank.

The wheels will be in motion in about 3 weeks.

well... what happens to the variable valve timing when you start modifying your car extensively?

Pretty much becomes irrelavant.

I was speaking to Jarus from D1 NZ who came down and had a drive in our last Drift Competition and he competes in a Nissan Cefiro with an Rb25DET running rb20 ecu and he says it works a treat.

    • 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"
