Hey there guys

I'm not sure if this has been asked, and if so can you lead me in the direction..

It's finally come time for me to swap out my beloved and molested RB20E and put in a RB25DET. So (assuming that the RB20E box (FS5W71C) isn't rated for the power output of a RB25DET) I'm kinda stuck at a predicament. From my knowledge, the RB25DET gearbox doesn't fit into a R33 GTS housing, so what gearbox? Does a RB30 box bolt in at all, or a RB20/RB25DE?

Cheers for any help

Huh, I thought the r33 rb25det box would fit.

rb30 box is smaller than rb25det box, much the same as a rb20 box.

Try and get a Series 2 box from an RB25DET. Some improvements were made and they're stronger.

Can anyone confirm wether a 25DET box will fit into a R33 GTS? And if not, what sorta work am I looking at doing?

If it fits easily, then I'll def. go with a S2 25DET box.

    • I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.
    • The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?
    • I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.
    • I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
    • Yeah, I would have said the same. It makes me suggest that there are other things wrong, such that the ECU is totally unhappy with the broken sensor. The only other thought here is that maybe it is shorted, which might cause a different issue to the typical "disconnected" sensor.
