Rb20det Into Cefiro Help !

[riyad]

hey guys, my names riyad and im from across the ditch looking for some help !

been on here for quite a while and have learned quite a fair bit and that everyone on heres pretty friendly.

now to what i need help on, im dropping an RB20det out of a R32 gtst into my cefiro what i basically need to know what to look out for ? whats gonna be a pain for me to do etc ?

also if someone could tell me whether the RB20de starter motor will work with the det motor ?

At present ive only started to disassemble the wiring, fuel lines and all the other crap from the engine.

Sorry if ive asked dum questions as in still only 17 and studying automotive engineering atm so i dont know everything, but i have to learn the hard way thats why im doing it myself (and with the help of a few mates of course )

any help will be appreciated guys and i definitely wil have more questions to come your way.

cheers riyad.

the starter bolts straight up mate .... actually , everything bolts straight up (note: r32 rb20 wiring is slightly different to cefiro on the engine , under the dash is the same though in memory)

ECU is fit,

accessories (near the ECU plugs) are different.

Engine acc. are different as well, shit like angle sensors, AFM, etc

[ENEMIE]

if its a 20de already you dont need to change then harness jusy plug the turbo computer in as the turbo and non turbo harness are the same

[Nic_A31]

Yes but the sensors still differ between early and mid model A31, and R32 GTST.

i believe late model Cefiro's have same wiring harness plugs and AFM as R32.

My Ceffy was turned turbo, they used the 20DE loom and everything on it, even the air flow meter, and just swaped in the bare motor...when I got an R32 AFM it didn't fit the Cefiro plug.

sweet so my starter motor will work ? even tho mines a factory manual cefiro ?

Yeah ive been told that the harness is quite similar thanks alot dude.

One more thing im after a nine bolt flywheel, ive been told the the RB30e one will work but is slightly bigger ? if true will a 9.5"/240mm clutch work with this and clear my gearbox ? what other options do i have as ive been told the RB20DE clutches are not worth it in the long run.

Try d1nz.com forums they have a full rite up on doing the conversion it helped me out good and proper when i did my conversion,

I think i used a rb30 flywheel and its been sweet as using excedy clutch, dont bother using de clutch as ive just heard clutches r crap n dont last

^^ as above the D1NZ guide is perfect for someone doing it first time, are you getting an engine loom with the engine ? if so it will plug straight into the body loom of the car, you only need to change a few wires under the fuse box.

Link... this is all you need..

RB20 and RB30 gearbox bellhousings are basically the same (different webbing) so a 30 flywheel will be fine.

hey guys, thanks for all the help its helped me get through the conversion pretty sweet. just a few more questions now. you guys that are running thick alloy rads, do you have any issues with the engine fan, as i trial fitted mine today and had about 3-4mm clearance between the 2 items. So i now im thinking i might need to run a electric fan to over come this problem... any thoughts ? also im going to be running a R32 front mount intercooler kit, i have a fair idea about where the holes need to be made for the piping but i would just like to reassure myself and if someone has pics it would be great.

any help would be appreciated, thanks alot guys.

[esky_mad]

do your best to avoid an thermo fan, how thick is you rad ? going to thick can actually make the car run hotter...

where you cut the holes, depends on how you mount the cooler, just take your time and you'll fine.

this is the same conversion im about to do, again but, I see the R32 runs an injector resistor where as the cefiro does not, is that an issue?

[esky_mad]

are you thinking of R32 GTR's that run a ballast resistor ? because RB20 powered GTST's do not have it. nor do cefiro spec'd RB20's

yea I see the GTR one is different but Im just trying to figure out what the silver doofa is on a R32 L/H strut tower, Im thinking some sort of fuel control
