My chick has a GTS R33 with RB20e engine in it. The engine is an absolute toy. I was thinking of throwing a RB30 in there as they are cheap as chips and everywhere. What mods if any are required to drop it in. I'm asuming the ECU and loom will need to be changed. Do the two engines share the same flywheel? Will the trans mount bolt up if I use the original RB20e 5 speed? Sump the same? etc. Someone would have done this for sure. Please post all your comments cheers.

damn sucks for yous over there with all your emitions stuff.

you could put a rb30e in. swap to the nissan cam cover and nobody would ever be the wiser as it would look exactly the same as the rb20e.. just a little taller.. plus you will gain torque and atleast 10kw at the wheels..

i wish i could have put a 26head now on my rb30.. just like im wishing i had put oil restrictors in the head as well... too much damn blowby!!

depending on the state u live in they might argue that the rb30 is too big

but put that aside im pretty sure the motor should bolt straight up to your existing box... you would use the clutch out of the rb30 aswell as the flywheel... and to drop it in you'd have to put the engine mount brackets off ur rb20 onto the rb30...

most rb30s have seen their day... unless you get a reco motor expect the annoying ticking of the lifters or just dont thrash it...

gearbox will bolt up. use your r33 engine mounts.

the thing is tho.. who is actually going to be able to tell it is a rb30? unless they look at the engine tag on the bottom of the block... cus if you put the 20e cam cover on nobody will be the wiser. even with my rb30de the mechanic thought it was a rb25de. even tho the intake pipe just touches the bonnet..

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
