Build Up Plans

[ONE-VIA]

im new to these forums so im asuming im in the right section if not could a mod move this thred to the right one. im from NS.com and they are aboubroad minded persone gurus with CA's and SR's but not very bright (IMO) on the RB25det motor and if i post this thred on NS they will tell me to come here and ask, so i thought il save abit of time and come here first.

*note these are all future plans as i am currently on my P's

and plan on having a reliable 300kw daily with a few track days every now and then, this thred is focusing on engine so dont tell me about driveline

RB25det (model undecided just know im not geting a neo)

z32 afm

power fc djetro

splitfire coil packs

fmic

discoe potatoe? t3/4?, GT35? or any other u might suggest for what i plan, dont care if its a high mount or a low mount turbo as the engine will be roughly a 2 year project itself (plan on putting engine in when off P's)

264 cams intake and exhaust

remove VCT (if it has it still on)

rods?

gasket?

700cc injectors

fuel pump and reg

oil pump and cooler

and 3'' turbo back

*is the stock throttle body worth boring out or am i beter of buy like a after market 80mm

cant realy think of anything else, i know im probly missing a shat load of parts but its 3am and cant realy think of anything else that i might need.

Welcome... The NS.Com guys are right to send you here...

I think you need to do a lot more searching/reading however, as basically there is nothing 'basic' that hasnt been covered or touched on in fairly good detail when it comes to RB25's and under 300rwkw.

Some threads to get you started

Also have a read of the Dyno Sticky in this section:

End of the day however it think you should stick with the SR, as your Victorian so there is all sorts of legal issues you'll have to contend with the more you modify, the harder it is.

a RB owner telling me to go SR

the CA motor was engineered by nissan and the RB motor was designed off it or other way round cant remember

the SR motor is from a tractor (seriously)

and 300kw@w is a bare minimum i want from that motor and i want it as a daily so need to be bullet proof just not a shot in my pocket

"the SR motor is from a tractor " thats f in funny because thats exactly what all the ones in NZ sound like

Im Melb also, and im well across legalities after my many different conversions, setups and so on.

SR is simply easier to keep on the street.

Either way, do what you want, ive linked you to the threads you need to read on the topic.

You just need to come up with the $25,000 to get it done now.

thats why this build up will take roughly 2 years

Z32 + D jetro doesnt work because djetro is speed density (MAFless) and you will need to use a rb26dett PFC djetro if your gonna go that way as there are no rb25 ones.

if 300rwkw is a bare minimum than budget for a full rebuild, cams arnt necessary.

and to be honest if you deadset on a RB conversion id just go straight to the RB26 as it would be cheaper in the long run to get the power your after.

Nismoid.... just wondering, what are the legality issues regarding a rb26DETT (from a 33GTR) into a 33 GTSt. Is it ok if the motor is newer than the age of the body its going into or do you need engineering certificates?

Was discussing this with my mate the other day but neither of us was sure

300kw with reliability from an SR Ash, we all know thats going to be pretty street un-friendly, track un-friendly and pocket draining.

Why would you want more than 300 anyway? In a pissy little Silvia its heaps of power. Especially for drift if thats what you mean about track days.

A Standard RB25 with cams and a 3071R would be plenty. You dont need a huge peak figure, midrange is what you want for street and drift.

Be a man and go the conversion, maybe consider an Engineers Certificate, if you dont have the money prepare for the car to be taken off the road.

Ive got a RB26 in my HR31 - its very easy, easier in a GTS-t actually than my car (due to brakes, gearboxes etc etc, all of which i have upgraded, but if i didnt it would have been a no-no).

RB26 for a R33 is a good choice, but not one for the person on a budget... RB26's cost money if you chase power, same as RB25's i guess but to keep a RB26 legal-ish and chase power is far easier hence you can make more and overall costs more

Well thats what i kinda meant, built a nice 250rwkw SR, light balanced car - love

[SilverCal]

Making 300kw+ from an rb with mods like an aftermarket ecu, fuel system, gt35, cams, coils ect,ect is a walk in the park throw in a set of rods and pistons and it becomes relaible, honestly though if i only wanted 'street' power i wouldn't want any more than say 250rwkw it is plenty for the street..

[ONE-VIA]

when i say track days i mean like time trials and circuit

just because i have a silvia dont asume im D1 mang

im more into drags and dyno's then drifting
