Hey guys,

If you had 5g's to spend with this base:

RB20DET

Stock motor

HKS SSQ BOV

Coilovers

FMIC

What parts would you buy / how would you modify this car with the available funds.

Really just looking for direction, I know I could spend alot more than this but this is all im really willing to.

Not looking for any particular power figures, just a bit more poke and for it to still be reliable at the same time.

Thanks :)

Sorry forgot to mention I also have full 3" zorst & rims.

So far it seems the 25 is the way to go. Any one have approximate costs for an engine and install? The gear box is on the way out how much extra do you think it would be if i got a 25 box as well?

Keep Checking the trader section for a motor and box they come up cheap from time to time and theres an R33 Power FC for 1k forsale in there right now.

im gonna throw up another option for you here,

HKS GTRS turbo Kit, GTR injectors, Z32 AFM, Re-Map the ECU and get a decent clutch, Thats If you dont want the hassle of swaping motors out etc,

If it were me, Id do the RB25+Box+PFC swap then do the above later on when some funds return.

If you dont have long term big plans for the car then i say do not do the RB25 conversion. Getting the car registered with an RB25 can be problematic.

I doubt a person who has done a 5K RB25 conversion would end up with any more performance then a modded RB20. Grab a 2530Kai, an ecu or a tune and your 220rwkws RB20 will be mega reliable, registerable, wont pop gearboxes and you will have change from the 5k to spend on subtle tweaks like perhaps a diff, some nicer suspension parts or better rubber. All round far better solution.

I cant believe people are suggesting a 5k RB25 conversion to someone who just wants to play around a little, by his words "I know I could spend alot more than this but this is all im really willing to." Unless he has the tools and know how the conversion wil cost more then 5k:( Would be nice and punchy on the street though,

Fark, talking RB25 conversion is like resorting to the use of a shotgun to get a 6yr old to brush their teeth :cheers:

I fail to see the relevance of trying to do a 25 for 5k... Its so gonna cost more than that and its gonna end up at a stockish level. Keep the 20, and work that fer sure! You'll end up with more power and money left to beef up your suspension so you can actually enjoy the power! Get an exhaust cam gear to bring the power band down a bit.

HKS2530

GTR injectors

REMAP + tune

Fuel pump

Turbotech bleed valve

All the above shouldn't cost you any more than $2,500 + labor if you can't do it yourself

That should see you 220rwkw as Roy said, plenty of reliability and fun street power

Spend the rest on a good suspension setup, diff as well as after-market clutch if you don't have one already and you will have plenty of fun with it

    • @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.
