hi.i have r33gts fitted with the rb20e.i would like to knw can i run the rb30e on the rb20e ecu with a piggyback to sort out the fuelling and ignition.just want abit of more power for now to move the heavy body.will the rb30 bolt straight in using the stock rb20 engine mounts.

forgot to mention im from south africa.want to do a rb25/30 at a latre stage.whats the difference between a r33 rb25de and arb25de neo.from what i've read the neo got smaller combustion chambers then the r33 rb25de so the comp should be high enough if you use the rb25 neo pistons

was thinking of doing that.how hard is it to fit a vh45 in a r33.i've read john's thread bt it dnt say if he had to mod a few things to fit it n most info u get is how to fit it into 300 zx n s13/14s n not much into skylines

It would be a pretty similar affair. Should be easier than a Silvia I would think as the bay would be bigger to start with.

should be an awesome car seeing what john done with his one but back to topic can my rb20e ecu run a rb30e.i'll be using everything on the rb20,inlet manifold,injectors,dissy and the exhaust manifold.i think it would run fine.im mostly after the extra touque of the rb30 till i upgrade later.

i think it should cz the rb30 in south african r31s ran with 21 deg timing.dnt knw if the injectors are the same size.it mite pick up a few extra kw cz the r33 rb20 inlet manifold seem to have bigger runners then the rb 30

Ive got an rb30e in my r33 and it smashes the pants off rb25de`s

the torque is good. Not so great on fuel tho

Engine mounts will be the same as the difference is in the block height

in terms of managment its best to use an rb30e loom and re wire it to suit the r33

Ebay has some cheap turbo kita for rb30e`s if u wanted more power later on

if u are serious pm me and ill send u some pics of my conversion and the wiring

contact nistune in australia who will be able to "chip" your rb20e ecu to run different fuel and timing maps to suit the rb30e.

my rb30 is n.a

basic mods: GTS style extractors 6-2-1, 2.5inch cat back zorst, pod filter, advanced ignition timing running premium fuel.

car has a 4.46:1 LSD, that helps ^.^ i dragged off a WRX to 100 km/h the other night

the car realistically has around 100 rwkw, with a cheap turbo kit it would have close to 170 rwkw

nice.im from south africa so my best bet will be to get a dastek piggyback ecu.currently got a pod n 57mm straight through exhaust with a rear can box.im making 85kw on da wheels.my best 1/4 mile is a 17.5 lol.with 100 on da wheels n more torque i mite get in the 16s

skit it will be hard for me to get the parts.i will be upgrading to a rb30det at a later stage just want sum extra power to move the heavy body.chris how high do u revyour rb30.seeing as the rb20e has a higher rev limiter i'll to let the piggyback ecu limit it to 6100rpm

    • 21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.
    • Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.
    • Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
    • @Rusty NutshI mate. Do you have a pinout diagram for the na neo auto ecu? 
    • Yeah thats the plan now. 🤞
