Most definately yes it's a good idea. A lot of people on these forums have done it and haven't looked back. The lighter weight of the 32 and the extra power the RB25 gives equals a hell of a lot more of a fun ride. Do a search on the forums, I'm sure you will find a fair bit of info, I know for a fact I saw a thread today about it but for the life of my I can't find it!

Not sure on the price buddy, I haven't looked into it myself but keep in mind, does that include the RB25 gearbox also?

As for Regency, I don't think it's a problem as long as...

A) You let them know

and

B) Make sure your brakes are capable

But just to be sure, call them and find out :mellow:

i put an rb25det in my 31. Best thing i ever did. rb25s are such great motors. Id check with regency also, may need to get engineers cert coz of increased in motor capacity, power etc. Definetly worth getting rb25det box. rb20det one will last a while but not forever!

if u buy a Rb25det box make sure the synchros between 3rd and 4th aint f**ked. if so ull be using red line shock proof like me till u need a rebuild of the trans or just new synchros put in and still a >1500 job.

ok jms have quoted me $5500 for rb25 supplied and fitted!! is that good or do u recomend somewhere else???

Yeah thats not a bad price but still shop around at Nisswreak and Zimports for prices

But just to be sure, call them and find out :happy:

Bigger brakes are always a good thing and with regency I thought all you had to do was swap the engine numbers over but could have changed now and need to get the engine converstion approved

Hope it goes well :stupid:

Yeah Ive done my research on the r32 rb25 conversion, 5500 is a bit much for just the engine supplied and fitted. You can pick up an rb25 + gearbox for 3000-3500 and most places charge between 1200-2000 for labour. Contact predator, he has his own site for the conversion and can help with any questions. The gearbox isnt essential unless you plan on going over 200rwkw.

hey thanks heaps guy looks like u have gone out of ur way to help! its much appreciated! thanks guys!!! ALSO.... d1 garage quoted 5200 for series 1 rb25det with rb20det 5speed, and 5500 for series 2 rb25det with rb20det 5speed....

QUOTE:

To give you more accurate price we will need to see the vehicle here at the workshop to check everything is in good order to complete the conversion.

The conversion price will include new engine oil / filter, spark plugs, coolant, fuel filter, gearbox oil, and diff oil.

To drive in drive out fitting an RB25DET complete engine package and using your original RB20DET 5 speed box (providing its manual) will be $5200 for a RB25DET series-1 engine and $5500 for a RB25DET series-2 engine.

thats what they had to say!

ALSO is the engineers cert extra ontop of the engine/install?

      @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣

      I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
