R32 did come with rb25de in the later models. GTS 25.

The cefiro and laurel also came out rb25de.

No rb25det though.

pretty sure you can fit rb20 cam covers and timinng belt covers on a rb25

nice and easy way to avoid trouble

yeah but that doesnt change the engine numbers

cant put the cam and timing covers on because of the VCT, the cover has a large bulge to get over it..

yeah RB25DE did come out in late model r32's, many people have told me they have got away without the engineers because of this.. the engine number does not say DET on it so thats what has made me think i might get away with it... engineers is only $450 depending weather or not the breaks need to be changed.. wich i dont think because i have a type m.

but.... would it be worthwhile taking the VCT away and running ajustable cam gear on both the intake and exhaust?? then i can put the rb20 covers on... will i get any loss out of doing this?? or would the car run better anyway?

i have heard that rb20 inlet cam needs to be put in to do this, is this true? if so is it an easy process, straight swap??

thanks leigh.

take off the coilpack cover and dont run custom cooler piping ie; keep the usual fmic piping that goes infront of the cam cover(this will 'hide' the vct buldge and wont make it so obvious that your cam cover nolonger says rb20.. wtf??. Cops wont know the difference unless they check your engine numbers, ive been pulled and they havent blinked twice, also went to mcleod to get my epa removed and they said nothing about it (granted they dont care about that stuff, its a vicroads thing). That being said if you get pulled by tmu you will get done. You can ring vic roads and say you blew your engine, give them your rb25 engine number and they will send you out a new rego sticker etc, again with this you run the risk of getting a operator who knows what they are doing and with your nice new rego sticker will come a roadworthy check and an epa notice. Engineers certsdont mean anything to the police, even with it they can still send you to the epa at their disgression. If you want pm me and ill tell you what i did - it worked aswell (all legal ofcourse!)

The R32 RB25DE's were non-vct so no lump. Externally look wise they look identical to an rb20. EVERYTHING (bolt on) apart from the inlet manifold (note there is 2 parts to the inlet, the plenum and the inlet manifold/runers) are interchangable with the rb20de/det motor.

IF you were to use the R33 VCT RB25 head and removed the vct simply throw an adjustable cam gear on it and either set it up with the same centerline as the r32 rb20det cam or what ever makes the sort of power you are after.

Here in SA dropping an R33 RB25DET or RB26DETT motor in an R32 GTST requires the R33 GTST/R32 GTR front callipers, stock ecu, turbo etc.

i thought the bolt pattern was different and the ajustable camgear does not fit.. cant remember exactly but something to do with 4 bolts or something.. so you can put a rb20 inlet cam in it and then you can bolt the ajustable cam gear on..i cant remember.. i will pull it off the rb25 on the weekend and have a look..

the reason being for all this is i bought a rb25 that was in a front accident.. it basically came with everything except whats on the front of the engine.. so all pullies, cam covers water pump.. all smashed even the backets on the block that hold the water pump on.. but i do alot of fabrication work so i can fix all that... i want to be able to use everything from the rb20 to replace what is missing which from alot of searching i am 90% sure i have everything i need.. i dont care about the engine number...

a couple of questions regarding this.. the rb25 is a series 1

- using rb20 coilpacks.. and the little box on top of the coilpack cover?

- the sensor thingy that bolts to the outside of the cam cover on the exhaust side of the cam..???

- alternator, powersteering pump, aircon stuff, etc i know this bolts on..

- the main drive for the belts that goes on the crank.. along with harmolic balencer.. etc.. ????

- upper and lower cam covers..??

- maybe the sump if i cant fix it...

the only thing that is ok on the front of the engine is the oil pump and the cam gears.. lol. everything else i need to replace salvaging as much as i can from the rb20 i already have...

i know this sounds like alot but everything else is with the engine.. i only paid $500 for it so i think it was worthwhile and i dont mind a little project..

any help would be much apreciated..

i think i have most of the loom so i am still summing up weather or not to go for a rb25 computer but i dont have it, or to do this and get the rb20 computer remapped.. i have r31Nismoids old gt30r waiting to go on it along with all other goodies... i am hoping for around 300rwkw...

I assume you are asking what you can use?

- using rb20 coilpacks.. and the little box on top of the coilpack cover?

coilpacks = yes.. ignitor box = no

- the sensor thingy that bolts to the outside of the cam cover on the exhaust side of the cam..???

I assume you mean crank angle sensor = no

- alternator, powersteering pump, aircon stuff, etc i know this bolts on..

yes, yes it does

- the main drive for the belts that goes on the crank.. along with harmolic balencer.. etc.. ????

Don't you mean the harmonic balancer? not sure, don't think so..

- upper and lower cam covers..??

no.. rb25 has the extra lobe coming out for the VCT.. rb20 top cover is flat, therefore won't fit from what I remember. Bottom, think it's not tall enough.

- maybe the sump if i cant fix it...

pretty sure sump is different too, never tried swapping that though

didnt the 4 door come with a RB25DE?
